Answer:

X = 34, Y=56

Step-by-step explanation:

BOA is an isosceles triangle.

Angle CBO = 90°

Angle DBO = 90 - 56 = 34

Angle ODB = 34° and ODB is x

Angle EBD is also 90°

Y = 180 - (90+34) = 56

The value of x is 34 degree and y is 56 degree.

Tangents to circles are lines that cross the circle at a single point. Point of tangency refers to the location where a tangent and a circle converge. The circle's radius, where the tangent intersects it, is perpendicular to the tangent. Any curved form can be considered a tangent.

We have, BOA is an isosceles triangle.

< CBO = 90°

So, < DBO = 90 - 56

<DBO = 34

and, <ODB = 34°

Now, let the angle ODB be x

As, from the figure < EBD is also 90°

So, <y = 180 - (90+34)  (Angle sum property)

<y = 56

Yes, all rational and irrational numbers have decimal expansions. Rational numbers can be expressed as terminating or repeating decimals, while irrational numbers have non-repeating, non-terminating decimal expansions.

In decimal form, rational numbers have a finite or repeating pattern of digits after the decimal point, while irrational numbers have an infinite, non-repeating pattern of digits after the decimal point. For example, the rational number 1/4 is expressed as 0.25, while the irrational number pi is expressed as 3.14159265358979323846... where the decimal goes on infinitely without repeating. In conclusion, every real number can be represented in decimal form, either as a terminating or repeating decimal, or as a non-repeating, non-terminating decimal.

Kaleb and Gage are standing approximately 12.72 feet apart from each other based on their angles of elevation to a basketball hoop that is 10 feet high.

Let's assume that Kaleb and Gage are standing on the same line perpendicular to the basketball hoop. Let's also assume that the distance between Kaleb and the hoop is x, and the distance between Gage and the hoop is y.

Using trigonometry, we can set up two equations based on the angles of elevation:

tan(40) = 10/x

tan(30) = 10/y

Solving for x and y:

x = 10/tan(40) ≈ 12.72 feet

y = 10/tan(30) ≈ 17.32 feet

Therefore, Kaleb and Gage are standing approximately 12.72 feet apart.

Answer:

To determine the cost of the shirt, we can set up an equation using algebra. Let x be the cost of the shirt in dollars. We know that Marissa spent a total of 45 on the hat and the shirt, and the hat cost 10. Therefore, we can write the equation:

x + 10 = 45

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 10 from both sides:

x = 35

Thus, the cost of the shirt is $35.

The nurse will advise the patient to take 1 ml of medication with each dose.

The physician orders medication at 400 mg po twice daily. The pharmacy supplies medication with a dosage strength of 2 grams per 5 ml.

How many milliliters does the nurse advise the patient to take with each dose?

The nurse should advise the patient to take 1 ml of medication with each dose.

To find the number of milliliters, the following formula will be used.

The length and width of the roof can be used to calculate the total square footage of the roof. For example, if the roof is 20 feet long and 10 feet wide, the total square footage would be 200 square feet.

Once the total square footage is known, the number of sheets of plywood needed can be calculated. Each sheet of plywood is 4 feet x 8 feet, or 32 square feet. Therefore, 200 square feet of roof would require (200/32 = 6.25) 6.25 sheets of plywood. In order to cover the entire roof, 7 sheets of plywood would need to be used.

Step-by-step explanation:

The diameter of circle C is [tex]x[/tex], which is [tex]5[/tex].

A circle is the collection of all points on a plane that are at a specified distance from another point (the radius) (the centre). A radius is any distance separating a point on a circle from its center. Any two radii are equal in length under the concept of a circle.

A semicircle is a half circle produced by splitting a circle into two equal parts. It is created when a line pierces the circle's center and touches its two ends.

Since [tex]CE[/tex] is a radius of the circle and the diameter is [tex]30[/tex] units long, we know that [tex]CE[/tex]is half the length of the diameter:

[tex]CE = 1/2[/tex](diameter)[tex]= 1/2([/tex]30 units)[tex]= 15[/tex] units

We are given that [tex]CE = 6x[/tex], so we can solve for [tex]x[/tex]:

[tex]CE = 6x = 15[/tex]

[tex]x = 15/6[/tex]

[tex]x = 2.5[/tex]

Now, we can use the fact that angle [tex]CED[/tex], where [tex]D[/tex] is the center of the circle, is a central angle that intercepts arc [tex]CD[/tex], to find the measure of angle [tex]CED[/tex].

Since the diameter of the circle is a straight line, it forms a [tex]180[/tex] degree angle at its endpoints. Therefore, angle [tex]CED[/tex] is half of this angle, which is:

angle [tex]CED = 1/2(180 degrees) = 90[/tex]degrees

We are given that angle [tex]CED[/tex] is [tex]30[/tex] degrees, so we can set up an equation:

angle [tex]CED = 30 = 6x[/tex]

Simplifying and solving for [tex]x[/tex]:

[tex]6x = 30[/tex]

[tex]x = 30/6[/tex]

[tex]x = 5[/tex]

Therefore, [tex]x[/tex] is equal to [tex]5[/tex].

Answer:

15 yards and 2 feet

Step-by-step explanation:

There are 3 feet in a yard

The points where the tangent line is vertical are (13/16, -5/16) and (-13/16, 5/16) and The slope of the tangent line is positive on the intervals t < -1 and t > 1, and negative on the interval -1 < t < 1.

(a) To find where the tangent line is horizontal, we need to find values of t where the derivative of y with respect to x (dy/dx) is equal to 0.

We have:

dy/dx = (dy/dt)/(dx/dt) = (5t^4 - 5)/(12t^2 - 3)

Setting dy/dx = 0, we get:

5t^4 - 5 = 0

t^4 = 1

t = ±1 or t = ±i

Substituting t = 1 into the parametric equations gives us the point (1,-4). Substituting t = -1 gives us the point (-1,4). Substituting t = i or t = -i gives us points on the imaginary axis, which are not part of the real plane.

Therefore, the points where the tangent line is horizontal are (1,-4) and (-1,4).

To find where the tangent line is vertical, we need to find values of t where dx/dt is equal to 0.

We have:

dx/dt = 12t^2 - 3

Setting dx/dt = 0, we get:

t^2 = 1/4

t = ±1/2

Substituting t = 1/2 into the parametric equations gives us the point (13/16, -5/16). Substituting t = -1/2 gives us the point (-13/16, 5/16).

Therefore, the points where the tangent line is vertical are (13/16, -5/16) and (-13/16, 5/16).

(b) To determine the intervals where the slope of the tangent line is positive or negative, we need to examine the sign of the derivative dy/dx.

From part (a), we know that dy/dx is equal to:

dy/dx = (5t^4 - 5)/(12t^2 - 3)

The denominator is always positive, so the sign of dy/dx is determined by the numerator.

For t < -1, we have 5t^4 - 5 > 0, so dy/dx > 0.

For -1 < t < 1, we have 5t^4 - 5 < 0, so dy/dx < 0.

For t > 1, we have 5t^4 - 5 > 0, so dy/dx > 0.

Therefore, the slope of the tangent line is positive on the intervals t < -1 and t > 1, and negative on the interval -1 < t < 1.

(c) To determine the intervals where the curve is concave upward or downward, we need to examine the sign of the second derivative d^2y/dx^2.

We have:

d^2y/dx^2 = ((d^2y/dt^2)(dx/dt) - (dy/dt)(d^2x/dt^2)) / (dx/dt)^3

Calculating the second derivatives, we get:

d^2y/dt^2 = 20t^3

d^2x/dt^2 = 24t

Substituting these into the expression for d^2y/dx^2, we get:

d^2y/dx^2 = (20t^3)(12t^2 - 3) - (5t^4 - 5)(24t) / (12t^2 - 3)^3

Simplifying this expression, we get:

Answer:

Hello! Yes, when completing the square, you are essentially transforming a quadratic equation from standard form to vertex form. The vertex form of a quadratic equation is given by:

y = a(x - h)^2 + k

where (h, k) represents the vertex of the parabola and 'a' is a constant that determines the shape and direction of the parabola.

To convert a quadratic equation from standard form (ax^2 + bx + c) to vertex form, we follow these steps:

1. Divide both sides of the equation by 'a' to make the coefficient of x^2 equal to 1.

2. Move the constant term (c/a) to the right-hand side of the equation.

3. Complete the square by adding and subtracting (b/2a)^2 on the left-hand side of the equation.

4. Factor the left-hand side of the equation as a perfect square trinomial.

5. Write the equation in vertex form by identifying the values of 'a', 'h', and 'k'.

Simple interest is a type of interest that is calculated only on the principal amount of a loan or investment, without taking into account any additional interest that may be added over time.

Simple interest is calculated as a percentage of the principal amount and is usually expressed as an annual rate.

The formula to calculate simple interest is:

Simple Interest = Principal x Rate x Time/ 100

Here we have

You are going to receive $2,000 in 6 years from now

The annual simple interest rate is 5%
