Answer: $22 per shirt and $14 per sweater

Step-by-step explanation:

     Let x be shirts and y be sweaters.

     We will write equations for the given situation.

5x + 8y = $222

6x + 5y = $202

     Next, we will graph both of these equations. The point of intersection will give the prices of one shirt and one sweater.

(22, 14)

➜ $22 per shirt

➜ $14 per sweater

According to given equations, any value of x less than 15.6 will result in the shopkeeper spending less than $100 on electricity.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, a left-hand side and a right-hand side, separated by an equals sign (=). The left-hand side and the right-hand side of an equation may contain one or more variables, and the equation is true only for certain values of these variables.

Let E be the amount the shopkeeper spends on electricity. Then, we have:

Total monthly expenses = Rent + Electricity = 8x + 15

Rent = 3x - 7

Substituting the value of Rent in the equation of total monthly expenses, we get:

8x + 15 = (3x - 7) + E

Simplifying this equation, we get:

5x + 22 = E

Therefore, the shopkeeper spends 5x + 22 dollars on electricity.

To find the value(s) of x for which the shopkeeper spends less than $100 on electricity, we can set up an inequality:

5x + 22 < 100

Solving for x, we get:

5x < 78

x < 15.6

Therefore, for any value of x less than 15.6, the shopkeeper will spend less than $100 on electricity. To verify this, we can plug in a value of x less than 15.6 and see if the resulting amount spent on electricity is less than $100. For example, if we let x = 10, then:

5x + 22 = (5 * 10) + 22 = 72

Since 72 is less than $100, we have verified that any value of x less than 15.6 will result in the shopkeeper spending less than $100 on electricity.

Answer:

Since the vertex is (0,-3), we know that the equation of the parabola will have the form:

y = a(x - 0)^2 - 3

where "a" is the coefficient that determines whether the parabola opens up or down.

To find the value of "a", we can use the fact that the parabola passes through the point (4, -7):

-7 = a(4 - 0)^2 - 3

-7 + 3 = 16a

-4 = 16a

a = -1/4

Substituting this value of "a" into the equation for the vertex form, we get:

y = -(1/4)x^2 - 3

So the equation of the parabola in vertex form is y = -(1/4)x^2 - 3, with vertex (0, -3) and passing through (4, -7).

There are 90 distinct arrangements of the letters in SPINNING.

In mathematics, permutation refers to the arrangement of objects in a specific order. A permutation of a set of objects is an ordered arrangement of those objects. For example, if we have a set of three objects {A, B, C}, then the permutations of this set would be {ABC, ACB, BAC, BCA, CAB, CBA}. The number of permutations of a set of n objects is denoted by n!. Permutations are commonly used in combinatorics, probability theory, and other areas of mathematics and science.

In the given question,

The word SPINNING has 8 letters, out of which two letters appear twice.

Let's first consider the distinct arrangements of the 6 unique letters (ignoring the repeated letters).

There are 6! ways to arrange these 6 letters in a row.

However, we need to adjust for the repeated letters. The letter "N" appears twice, so we divide by 2! to account for the fact that the two N's can be arranged in 2! = 2 ways without changing the arrangement of the other letters. Similarly, the letter "I" also appears twice, so we divide by another 2!.

Therefore, the total number of distinct arrangements of the letters in SPINNING is:

6! / (2! x 2!) = 360 / 4 = 90.

So there are 90 distinct arrangements of the letters in SPINNING.

Answer: the radius of the circle is 14 cm. :)

Step-by-step explanation:

To find,

The radius of the circle.

Solution,

The radius of the circle will be 14 cm.

We can easily solve this problem by following the given steps.

According to the question,

Length of a rectangular wire = 32 cm

The breadth of a rectangular wire = 12 cm

This wire is bent into the shape of a circle.

So,

The perimeter of the rectangle = Circumference of the circle

We know the formula for the perimeter of a rectangle is as follows:

P = 2(Length+Breadth)

P = 2(32+12) cm

P = 2(44) cm

P = 88 cm

We know that the formula to find the circumference of the circle is given as follows:

C =

2πr = 88 cm

2×22r/7 = 88

44r/7 = 88

Using the cross multiplication method,

44r = (88×7)

r = (88×7)/44

r = (2×7) cm

r = 14 cm

Hence, the radius of the circle is 14 cm.

Answer:

14.01 cm

Step-by-step explanation:

The length of the wire is equal to the perimeter of the rectangle. So, the length of the wire is:

When this wire is bent into a circle, its length becomes equal to the circumference of the circle. The formula for the circumference of a circle is:

(let r = radius)

2 × π × r

So, we can write:

Solving for r, we get:

So, the exact value of the radius of the circle formed by bending this rectangular wire is 14.01 cm.

The dimensions of each half rectangular brick are, length 15 cm, and height 10 cm.

Let the original dimensions of the rectangular brick be length L, breadth B, and height H.

According to the problem statement, each dimension of the original brick is 5 cm larger than the desired dimensions of each half brick.

Therefore, the dimensions of each half brick are;

(L-5)/2, (B-5)/2, and (H-5)/2.

Since the two half bricks have identical dimensions, we have:

(L-5)/2 = (B-5)/2 = (H-5)/2

Simplifying this equation, we get:

L-5 = B-5 = H-5

Therefore, L = B = H + 5.

Now, the volume of the original brick is L x B x H, and the volume of each half brick is [(L-5)/2] x [(B-5)/2] x [(H-5)/2].

Since the two half bricks have the same dimensions, their volumes are equal. Thus, we have:

(L-5)/2 x (B-5)/2 x (H-5)/2 = (L x B x H)/2

Substituting L = B = H + 5, we get:

(H+5-5)/2 x (H+5-5)/2 x (H-5)/2 = (H x H x (H+5))/2

Simplifying this equation, we get:

(H+5)/2 x (H-5)/2 x H/2 = (H x H x (H+5))/2

Cancelling out the factor of 1/2, we get:

(H+5)(H-5)H = H x H x (H+5)

Simplifying this equation, we get:

H³ - 125H = H³ + 5H²

Subtracting H³ from both sides, we get:

-125H = 5H²

Dividing both sides by 5H, we get:

H = -25 or H = 0

Since H represents the height of the brick, it must be positive. Therefore, we have H = 0, which implies that the original brick has zero height. This is not a valid solution, so we reject it.

Therefore, the only valid solution is:

H = 25 cm

Substituting this value of H in the equation L = B = H + 5, we get:

L = B = 30 cm

Therefore, the dimensions of the original brick are:

Length = L + 5 = 35 cm

Breadth = B + 5 = 35 cm

Height = H + 5 = 30 cm

And the dimensions of each half brick are:

Length = Breadth = 15 cm

Height = 10 cm

The tension in cable B is 400 N.

What is tension in cable ?

Tension is the force transmitted through a string, rope, cable, or wire when it is pulled taut by forces acting from opposite ends. It is the pulling force that exists between two objects that are connected by a rope or cable and is usually measured in newtons (N) or pounds (lbs). The tension in a cable or rope can be calculated using the principles of equilibrium, where the sum of the forces acting on the object is equal to zero. In other words, the tension in a cable is the force that must be applied to the cable in order to keep it taut and maintain its position or prevent it from breaking.

According to the question:
To solve this problem, we need to use the fact that the sum of the forces acting on the sign must be zero in order for the sign to be in equilibrium. We can break down the weight of the sign into its components parallel and perpendicular to the cables:

F_parallel = 800 N * sin(30°) = 400 N

F_perpendicular = 800 N * cos(30°) = 693.2 N

The tension in cable A must balance the perpendicular component of the weight of the sign, so we have:

Tension_A = 693.2 N

The tension in cable B must balance the horizontal component of the weight of the sign, so we have:

Tension_B = 400 N

Therefore, the tension in cable B is 400 N.

In the function k(x) = 3(2^(-8x)), the domain is all real numbers (-∞, +∞) and the range is all positive real numbers (0, +∞).

Hi! I'd be happy to help you find the domain and range of the function k(x) = 3(2^(-8x)). The domain of a function is the set of all possible input values (x-values) for which the function is defined, while the range is the set of all possible output values (y-values) that the function can produce.

For k(x) = 3(2^(-8x)), the function is an exponential function, and exponential functions are defined for all real numbers. This means that you can input any real number value for x, and the function will produce a valid output. Therefore, the domain of k(x) is all real numbers, which can be represented as (-∞, +∞) or R.

To find the range, we need to consider the behavior of the exponential function as x increases and decreases. As x goes to negative infinity, 2^(-8x) approaches infinity, and thus 3(2^(-8x)) also approaches infinity. As x goes to positive infinity, 2^(-8x) approaches 0, but since we are multiplying by 3, the minimum value of k(x) is 0. However, the function never actually reaches 0, so the range is all positive real numbers, which can be represented as (0, +∞).

Answer:

[tex]h(0) = -16(0)^2 + 128[/tex]

[tex]= 128[/tex]

Therefore, the rocket goes to a maximum height of 128 feet.

4. The axis of symmetry of the parabolic path of the rocket is the vertical line that passes through the vertex of the parabola. Since the coefficient of [tex]t^2[/tex] is negative, the parabola opens downwards, and the vertex represents the maximum point of the path. As we found in question 2, the time at which the maximum height occurs is t = 0, so the axis of symmetry is the vertical line passing through t = 0.

5. To find when the rocket hits the ground, we need to find the time t at which h(t) = 0. Substituting [tex]h(t) = -16t^2 + 128[/tex], we get:

[tex]-16t^2 + 128 = 0[/tex]

Solving for t using the quadratic formula, we get:

t = (0 ± √(0^2 - 4(-16)(128))) / (2(-16))

= (±√8192) / (-32)

= ±8

Since time cannot be negative, the rocket hits the ground after approximately 8 seconds.

6. To find how high the rocket is at t = 2 seconds, we can substitute t = 2 into the equation h(t) = -16t^2 + 128:

h(2) = -16(2)^2 + 128

= -64 + 128

= 64 feet

Therefore, the rocket is at a height of 64 feet at 2 seconds.

7. To find when the rocket is at a height of 252 feet, we need to solve the equation [tex]-16t^2 + 128 = 252[/tex]. Rearranging and solving for t, we get:

[tex]-16t^2 + 128 = 252[/tex]

[tex]-16t^2 = 124[/tex]

[tex]t^2 = -124/-16[/tex]

t^2 = 7.75

t ≈ ±2.78 seconds

Since time cannot be negative, the rocket is at a height of 252 feet after approximately 2.78 seconds.

8. The graph coordinates of the rocket's path can be plotted using the function [tex]h(t) = -16t^2 + 128[/tex]. The x-axis represents time t in seconds and the y-axis represents the height of the rocket in feet. We can plot points on the graph by substituting different values of t into the equation and plotting the resulting height. For example, some common points to plot include the vertex at (0, 128), the point where the rocket hits the ground at approximately (8, 0), and the point where the rocket is at a height of 252 feet at approximately (2.78, 252). We can also plot other points by substituting different values of t into the equation and plotting the resulting height.

The coordinates of the image if triangle ABC is translated 4 units down would be: A′(1, -6), B′(9, -6), C′(5, -2)

To translate the triangle 4 units down, we need to subtract 4 from the y-coordinate of each vertex.

Vertex A has coordinates (1, -2), so its image A' after the translation is (1, -2 - 4) = (1, -6).

Vertex B has coordinates (9, -2), so its image B' after the translation is (9, -2 - 4) = (9, -6).

Vertex C has coordinates (5, 2), so its image C' after the translation is (5, 2 - 4) = (5, -2).

Therefore, the coordinates of the vertices of triangle ABC after it is translated 4 units down are A′(1, −6), B′(9, −6), and C′(5, −2).

So, the answer is option A: A′(1, −6), B′(9, −6), C′(5, −2)..
