Can Someone Please Help Me With This Problem?Use The Information Given In The Figure To Find The Length

Answers

Answer 1

Answer:

BC = 62

Step-by-step explanation:

There are 3 triangles total in the figure shown, one large triangle, and two smaller triangles created by the segment BC. Now, look at triangle ACD and see that is a scaled version of common right triangle.

Some common right triangles are 3-4-5, 5-12-13, and 7-24-25. You may be able to see a pattern here where the square of the smallest side length is equal to the sum of the other two side lengths. Triangle ACD happens to be a scaled form of a 5-12-13 triangle. The triangle is scaled by a factor of 3. So the respective side length of AD is 12 * 3 = 36.

Now look at triangle ABD. We have two of the three side lengths.

AD = 36

AB = 85

We want to find BC, so we will use the pythagorean theorem, with (x + 15) to represent the length of BD.

35² + (x + 15)² = 85²

1225 + (x + 15)² = 7225

(x + 15)² = 6000

x + 15 = ±√6000

x = -15 ± √6000

Our equation provides two answers, but the negative value doesn't make sense because length can't be negative, so use the positive length for this application.

x = -15 + √6000

x = 62.4596

Rounded to the nearest whole number, the length of BC is 62.

Reflect (6,-4) across the -axis. Then reflect the result across the -axis. What are the coordinates of the final point?”

Answers

The coordinates of the final point after the reflections across the x-axis twice is (6, -4)

What are the coordinates of the final point?

Reflecting a point across the x-axis means that we keep the x-coordinate the same, but change the sign of the y-coordinate.

So reflecting (6,-4) across the x-axis gives us the point (6,4).

Reflecting this result again across the x-axis means that we keep the x-coordinate the same, but change the sign of the y-coordinate again.

So reflecting (6,4) across the x-axis gives us the point (6,-4).

Therefore, the final point after both reflections is (6, -4).

Using function notation, write the formula for the function g(x) whose graph is obtained by
morizontally stretching the graph of f(x) by a factor of 2.

Answers

The function notation  formula is given as g(x) = f(x/2)

Function notation explained.

Function notation is a way of representing a mathematical function using symbols and variables. It is a shorthand way of writing the rule or formula for a function, which specifies how the input values (usually denoted by x) are transformed into output values (usually denoted by y or f(x)).

In function notation, a function is typically represented by a letter (usually f, g, or h) followed by parentheses that enclose the input value or variable, such as f(x), g(t), or h(y). This notation indicates that the function takes an input value (x, t, or y) and produces a corresponding output value (f(x), g(t), or h(y)).

Assuming we want to horizontally stretch the graph of f(x) by a factor of 2 to obtain the graph of g(x), the function notation for g(x) can be written as:

g(x) = f(x/2)

In other words, we plug in x/2 instead of x in the formula for f(x) to get the corresponding value of g(x) that is horizontally stretched by a factor of 2. This is because when we substitute x/2 in f(x), it effectively multiplies the input (x) by 2, which horizontally stretches the graph by a factor of 2.

The length of a rectangle is twice its width. If its perimeter is 60 m, then its area is (a) 600 m², b) 400 m², c)150 m², d) 200 m²​

Answers

Answer:

The answer is (d) 200 m².

Step-by-step explanation:

Let's denote the width of the rectangle as w. Then the length of the rectangle is twice the width, which means the length is 2w.

The perimeter of a rectangle is given by the formula:

P = 2l + 2w

Substituting the values, we get:

60 = 2(2w) + 2w

Simplifying the equation, we get:

60 = 6w

Dividing both sides by 6, we get:

w = 10

So the width of the rectangle is 10 m and the length is twice the width, which is 20 m.

The area of a rectangle is given by the formula:

A = lw

Substituting the values, we get:

A = 10 x 20

Simplifying the equation, we get:

A = 200

Therefore, the area of the rectangle is 200 m².

If Jean, Stellah and Dee’s respective contributions to the start-up capital are R225 000,00, R150 000,00, and R75 000,00, and Dee’s share of the profit in the company’s first year of operation is R40 000,00, what was the total profit made by the company that year?

Answers

According to the given rate the total profit made by the company in the first year is R240,000.

What is rate?

The problem statement does not provide enough information to determine the rate of return or interest rate. In the absence of this information, it is not possible to calculate the rate of return or interest rate earned on the capital contributions or on the profit made by the company.

According to the given information:

According to the agreement, the profit made by the company should be divided among the partners in the ratio of their capital contributions, which in this case is 225,000:150,000:75,000 or 3:2:1.

Let's assume that the total profit made by the company in the first year is P. Dee's share of the profit is R40,000, which is 1/6 of the total profit, since her capital contribution is 1/6 of the total capital.

So, we can set up the equation:

1/6 * P = R40,000

Multiplying both sides by 6, we get:

P = R240,000

Therefore, according to the given rate the total profit made by the company in the first year is R240,000.

Given the above conditions with regard to Rolle's Theorem, the answers are:

Therefore, the solution is:

F(0) = 0

f(4) = (-8) e^4

C = 1

What is the explanation for the above response?


To find F(0), we can simply substitute x=0 into the expression for f(x):

f(0) = (0^2 - 4(0)) e^0 = 0

To find f(4), we can substitute x=4:

f(4) = (4^2 - 4(4)) e^4 = (-8) e^4

Next, we need to find the critical point(s) of f(x) on the interval [0,4]. To do this, we find the derivative of f(x) and set it equal to zero:

f'(x) = (2x-4) e^x + (x^2-4x) e^x = (x^2-2x) e^x

Setting f'(x) equal to zero, we have:

(x^2-2x) e^x = 0

Since e^x is never zero, we can divide both sides by e^x to get:

x^2 - 2x = 0

Factoring out x, we have:

x(x-2) = 0

Therefore, the critical points on [0,4] are x=0 and x=2.

Since both critical points are in the open interval (0,4), Rolle's Theorem applies. This means there exists a number c in (0,4) such that f'(c) = 0. To find this value of c, we can simply take the average of the critical points:

c = (0 + 2)/2 = 1

Therefore, the solution is:

F(0) = 0

f(4) = (-8) e^4

C = 1

The result of the matrix multiplication for  F³  is determined as [[1,0],[-2,3]].

What is matrix multiplication?

Matrix multiplication is a mathematical operation that takes two matrices and produces a new matrix.

Given two matrices A and B, the resulting matrix C is obtained by multiplying the elements of the rows of matrix A with the corresponding elements of the columns of matrix B, and summing the products.

To calculate F³, we need to multiply the matrix F by itself three times:

F² = F * F = [[1,0],[2,-3]] * [[1,0],[2,-3]] = [[11+02,10+0(-3)],[21+(-3)2,20+(-3)(-3)]] = [[1,0],[-4,9]]

F³ = F * F² = [[1,0],[2,-3]] * [[1,0],[-4,9]] = [[11+02,10+09],[21+(-3)(-4),2*0+(-3)*9]] = [[1,0],[-2,3]]

equation of oscillating circle of curve y=1/4 x^2 +2 at (2,1)

Answers

The equation of the oscillating circle of the curve y = ¹/₄ x² +2 at point (2,1) is (x - 5/2)² + (y - 1)² = 1/4.

What is the equation of the oscillating circle?

To find the equation of the oscillating circle of the curve y = ¹/₄ x² +2 at point (2,1), we need to follow these steps:

Find the first and second derivatives of the given curve:

y = ¹/₄ x² + 2

y' = ¹/₂ x

y'' = ¹/₂

Use the first and second derivatives to find the equation of the tangent line to the curve at point (2,1):

y - 1 = 1/2(x - 2)

y = 1/2 x + 0.5

Find the perpendicular bisector of the tangent line at point (2,1):

The slope of the tangent line is 1/2, so the slope of the perpendicular bisector is -2.

y - 1 = -2(x - 2)

y = -2x + 5

Find the intersection of the perpendicular bisector with the x-axis:

When y = 0, -2x + 5 = 0, so x = 5/2.

Find the center of the oscillating circle:

The center of the oscillating circle is (5/2,1).

Find the radius of the oscillating circle:

The radius of the oscillating circle is the distance between the center and the point of tangency, which is:

r = √[(2 - 5/2)² + (1 - 1)²]

r = [1/4 + 0] = 1/2.

Write the equation of the oscillating circle in standard form:

The equation of the oscillating circle is:

(x - 5/2)² + (y - 1)² = (1/2)².

Answers

The composite function [g . f](x) when evaluated has its value to be 4x² + 20x + 22

Calculating the composite function

Given that, we have the following functions

f(x) = 2x + 5

g(x) = x² - 3

To find [g . f](x) we make use of g(f(x)), where we first need to find f(x) and then plug it into g(x) in place of x.

Given, f(x) = 2x + 5 and g(x) = x^2 - 3.

So,

g(f(x)) = g(2x + 5) [Substitute f(x) in place of x in g(x)]

g(f(x)) = (2x + 5)² - 3 [Substitute 2x + 5 in place of x in g(x)]

g(f(x)) = (4x² + 20x + 25) - 3

g(f(x)) = 4x² + 20x + 22

Krystal throws a rappelling rope at a speed of 10 m/s down a 50 m cliff.

When will the rope hit the ground?

Use the drop-down to put the correct order to solve for when the rope will hit the ground. (In the Image below)

Answers choices for each equation are: 1 , 2 , 3 , 4 , 5 , 6

Answers

Answer:

  3 6 4 2 1 5

Step-by-step explanation:

You want to know the sequence of solving the problem of finding the time until the rope hits the ground when thrown at 10 m/s down a 50 m cliff.

Setup

The equation describing the height of the rope is of the form ...

  h(t) = -4.9t² +v₀t +h₀

where v₀ is the initial upward velocity (meters per second), and h₀ is the initial height (meters).

Here, the initial velocity is described as 10 m/s downward, so we expect v₀ to have a value of -10. However, the offered equation(s) show v₀ = +10, so we will be solving the problem assuming the rope is initially thrown upward.

For v₀ = 10 and h₀ = 50, the equation for the height of the rope is ...

  h(t) = -4.9t² +10t +50 . . . . . . . step 1

Solution

We want to find the time (t) when the height is 0, so we substitute h(t) = 0 into the above equation:

  0 = -4.9t² +10t +50 . . . . . . . . step 2

This can be solved nicely using the quadratic formula. We recognize that a=-4.9, b=10, c=50, so the filled-in formula is ...

  [tex]t=\dfrac{-10\pm\sqrt{10^2-4(-4.9)(50)}}{2(-4.9)}\qquad\textsf{step 3}[/tex]

Simplifying this and taking the square root, we have ...

  [tex]t\approx\dfrac{-10\pm32.86}{-9.8}\qquad\textsf{step 4}[/tex]

Evaluating this expression gives ...

  t ≈ -2.33  or  t ≈ 4.37 . . . . . . . . . step 5

Writing the answer as a sentence is the last step:

  The rope will hit the ground in about 4.37 seconds. . . . . . step 6

The sequence of step numbers is ...

  3 6 4 2 1 5

__

Additional comment

The equation assume ballistic motion, with no air resistance or other impediment to the rope falling only due to gravity. We assume that Krystal plans to use the rope for rappelling, so it is probably coming uncoiled as it falls. That process usually changes the motion from one that is purely defined by the force of gravity.

We also note that if the initial throwing direction is downward, then the solution to the equation h(t) = -4.9t² -10t +50 is actually t ≈ 2.33 s.

What is differential calculus?

Differential calculus is the part of calculus that is concerned with the rate of change of quantities.

The steps to determine the intervals where f(x) = x⁴ - 2·x³ is increasing or decreasing, or constant are presented as follows;

The derivative of the function is first found using calculus, differentiation as follows;

f'(x) = 4·x³ - 6·x²

The critical points at which the slope of the graph changes from increasing are found at the points where f'(x) = 0 as follows;

f'(x) = 0 = 4·x³ - 6·x²

4·x³ - 3·x² = 0

2·x²·(2·x - 3) = 0

Therefore, at the critical points, x = 0, and x = 3/2

The first derivative test can be used to determine the interval the function is increasing or decreasing as follows;

f(x) is increasing at x < a, if f'(x) > 0 for x < a and f(x) is decreasing at x > a if f(x) < 0 at x > a, where a is a critical point

f(x) is decreasing at x < a, if f'(x) < 0 for x < a and f(x) is increasing at x > a if f(x) > 0 at x > a,

The concavity of the function at x = a if f'(x) = 0 at x = a can be determined using the second derivative as follows;

f''(x) = 12·x² - 12·x

f''(x) > 0 at x = a if f(x) is concave up

f''(x) < 0 at x = a if f(x) is concave down

When a = 0, we get;

f''(0) = 12 × 0² - 12 × 0 = 0

f''(0.5) = 12 × 0.5² - 12 × 0.5 = -3 (Concave down)

f''(-0.5) = 12 × (-0.5)² - 12 × (-0.5) = 9 (Concave up)

f''(0) = 0 at x = 0, therefore, x = 0 is an inflection point

f'(-1) = 4·(-1)³ - 6·(-1)² = -10

f'(1) = 4·(1)³ - 6·(1)² = -2

Therefore, the graph changes from decreasing and is also decreasing at x > 0

Similarly we get;

f'(2) = 4·(2)³ - 6·(2)² = 8 (Increasing)

Therefore;

f'(1) = 4·(1)³ - 6·(1)² = -2

There

f''(3/2) = 12 × (3/2)² - 12 × (3/2) = 9

The second derivative at x = 3/2 = 9 > 0, therefore;

The function, f(x) is concave up at x = 3/2

Therefore, we get the following table;

*ITS NOT 288 I ALREADY TRIED!*

Answers

The total garden area obtained by adding the new area of the garden is obtained as 36  sq. ft.

Explain about the rectangular shape?

Your polygon's four sides must be two congruent pairings in order to have two pairs with parallel sides.

The length of the left and right sides, as well as the base and top, will be equal. A four-sided polygon with two sets of parallel, congruent sides with four internal angles of 90° each is required to be a rectangle.

Given data:

current area of garden = 24 square feet.

Coordinates of other garden:

(−17, 15), (−20, 15), (−17, 11), and (−20, 11)

Length of new garden = -20 + 17 = 3 ft.

Width of new garden = 15 - 11 = 4 ft.

Area of new garden = length * width

Area of new garden = 3ft * 4 ft

Area of new garden = 12 sq. ft.

total area of the garden = current area +  new garden area

total area of the garden = 24 sq. ft. + 12 sq. ft.

total area of the garden = 36  sq. ft.

Thus, the total area of the garden obtained by adding the new area of the garden is obtained as 36  sq. ft.

a) Write the next two numbers in the number chain. 1 ► 3 ► 11​

Answers

The next two numbers in the sequence are 35 and 107.

What are the next two numbers in the sequence?

The given number chain seems to be following the pattern of adding the previous number multiplied by a specific factor.

To find the next two numbers in the sequence, we will use the same pattern.

1 ► 3 ► 11 ► ?

To get the next number in the sequence, we multiply the previous number by 3 and add 2.

So, the next number in the sequence would be:

11 x 3 + 2 = 35

Therefore, the next number in the sequence is 35.

To get the number after 35, we apply the same pattern:

35 x 3 + 2 = 107

Therefore, the next number in the sequence is 107.

Hence, the next two numbers in the sequence are 35 and 107.

So the complete number sequence is: 1 ► 3 ► 11 ► 35 ► 107 ►

What is area of Rhombus?

To calculate the base of the rhombus, we will follow the steps below;

write the formula for calculating the area of a rhombus

area of a rhombus = b × h

where h is the height of the rhombus and b is the base of the rhombus

Given:

Base = 21 cm

Height = 17.3 cm

We know area of Rhombus =  base x height

                                             = 21 x 17.3

                                             = 363.3 cm²

So, the area of Rhombus is 363.3 cm².

Answers

Answer:23200cm^3

Step-by-step explanation:

we are going to watch this figure as 2 different prisms. 1st-parallelepiped

and 2nd-trapezoidal prism;

The volume of the parallelepiped is equal to a*b*c which is the product of its sides(width, height, and length) and in this case, it is equal to V1=a*b*c=10*12*80(because the trapezoidal prisms side is parallelogram and facing sides of parallelogram are equal so c=80cm)=9600cm^3;

V2=Area of base*h

area of base is equal to area of transpazoid which is

A=((a+b)/2)*h=(12+22)/2*10=34/2*10=17*10=170cm^2

and as i said earlier h=80 because its a parallelogram so,

V2=170+80=13600cm^3

V=V1+V2=9600+13600=23200cm^3

When concentrations of formaldehyde in the air exceed 33 μg/ft3 1 μg=1 microgram=10−6 gram, a strong odor and irritation to the eyes often occurs. One square foot of hardwood plywood paneling can emit 3365 μg of formaldehyde per day. A 5 ft by 7 ft sheet of paneling is attached to a wall in a room having floor dimensions of 10 ft by 10 ft and height of 7 ft.

Answers

Since the limit is just 33 μg/ft³, it exceeded the given limit. Thus, with this condition, there would be strong odor and irritation of the eyes.

What do you mean by volume?

A cube's volume is defined as the total number of cubic units that it takes up in its entirety. To calculate the cube's volume, we need to know how long each cube side is. In order to compute volume, use the following equation: Side x Side x Side equals volume.

33 μg/ft³ is the maximum allowed formaldehyde concentration. Our foundation should be this. It is now assumed that wood panelling generates 3,365 μg of formaldehyde per square foot. The wood panelling measures 5 feet by 6 feet; therefore the area is equal to 30 ft². As a result, the formaldehyde emission is calculated as follows: Emitted formaldehyde = (3,365 μg/ft²) (30 ft²) = 100,950 μg

The size of the room is then measured:

V = 10 ft × 10 ft × 6 ft = 600 ft³

Let's compare the ratio to our basis:

Ratio = 100,950 μg/600 ft³ = 168.25 μg/ft³

Since the limit is just 33 μg/ft³, it exceeded the given limit. Thus, with this condition, there would be strong odor and irritation of the eyes.

The mapping diagram represents a relation where x represents the independent variable and y represents the dependent variable.
(PLS HELP 100 POINTS)

Answers

We can conclude after answering the provided question that Because each element in the domain is paired with exactly one element in the range, this mapping diagram represents a function.

what is domain?

The domain of a function is the range of possible values that it can accept. These numbers represent the x-values of a function such as f. (x). The domain of a function is the range of possible values that can be used with it. This set includes the value returned by the method after inserting the x value. A function with y as the dependent variable and x as the independent variable has the formula y = f. (x). When a single value of y can be produced successfully from a value of x, that value of x is said to be in the function's domain.

Each element in the domain (set of x values) is paired with exactly one element in the range (set of y values), as represented by arrows connecting the two sets in the mapping diagram. For example, the domain element 2 is paired with the range element 4, and the domain element -1 is paired with the range element 1.

Because each element in the domain is paired with exactly one element in the range, this mapping diagram represents a function. The function is not one-to-one because multiple domain elements are paired with the same range element (for example, both -2 and 3 are paired with 1).

Find the volume of the solid whose base is a triangle with vertices (0,0), (0,3), and (5,0). Slices perpendicular to the x-axis are semicircles. Enter answer using exact values.

Answers

The volume of the solid whose base is a triangle with vertices (0,0), (0,3), and (5,0) is 25π/12 cubic units.

What is a triangle?

A triangle is a closed geometric shape that is formed by connecting three line segments. These line segments are called sides, and the points where they meet are called vertices. A triangle has three sides, three angles, and three vertices.

To start, let's graph the triangle to get a better understanding of the problem:

(0,3)   *

       |\

       | \

       |  \

       |   \

       |    \

(0,0)   *-----*-----> x

        (5,0)

The height of this slice is given by the line from the point (x,0) to the point (0,3), which has equation y = 3/5 * x + 0. The radius of the semicircle is half the height of the slice, which is given by the equation r = 3/10 * x.

The area of a semicircle is πr²/2, so the volume of this slice is:

V(x) = π * (3/10 * x)² / 2 * dx

To find the total volume of the solid, we need to integrate this expression over the range of x values that covers the entire base of the solid, which is from x=0 to x=5:

V = ∫₀₅ π * (3/10 * x)² / 2 dx

V = π/20 * ∫₀₅ x² dx

V = π/20 * [x³/3] from 0 to 5

V = π/20 * (5³/3)

V = π/4 * (25/3)

V = 25π/12

Therefore, the volume of the solid is 25π/12 cubic units.
