Answer:

for 15 the answer is 61 and

16 the answer is 82

Step-by-step explanation:

First you need to know that these are vertically opposite angles and that the vertical opposite angles are always the same.

therefore in qn 15.

- the 125 degrees angle is vertically opposite to the 64 + x angle therefore we make an equation

64 + x = 125 (then minus 64 on both sides)

(64 - 64)+ x = 125 - 64

x = 125 - 64

x = 61

the same goes for qn 16.

85 + x = 167 (then minus 85 in both sides)

85 - 85 + x = 167 - 85

x = 167 - 85

x = 82

Answer:

the domain of the function is y-2vx-5 is 0x25

The domain of the function  x≥ 5.

The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f(x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.

The domain takes all of the potential input values from the set of real numbers, while the range takes all of the function's output values.

We have the function y = √(x- 5)

The domain is the x values operate, often known as the horizontal axis.

The Range is y values on the vertical axis.

As, the radical never gives Negative Value.

So, x- 5 ≥ 0

and, x≥5

Thus, the domain is x≥ 5.

Answer:

Step-by-step explanation:

The marked-down price is ...

  $50 × (1 - 20%) = $50 × 0.80 = $40

Barry gets a 10% discount on that price, so his discount is ...

  $40 × 0.10 = $4

Barry pays $40 -4 = $36.

__

Barry would be correct if the "additional 10% off" were based on the original price, but it isn't. It applies to the already-discounted price.

Answer:

The answer is =−7

Step-by-step explanation:

This is a composition of functions

f(x)=x+8

g(x)=x2−6x−7

Answer:

angle3 and angle4 are complementary.

A. true

B. false

Answer is B False

Step-by-step explanation:

Complementary angles are two angles whose measures add up to 90°

The coordinates of the figure W'X'Y'Z' are W' (5, 4), X' (4, 1), Y' (1, 6) and Z' (3, 8).

The coordinates of the quadrilateral WXYZ is W(-4, 5), X(-1, 4), Y(-6, 1) and Z(-8, 3).

We need to find the coordinates of the figure W'X'Y'Z', in which figure WXYZ is rotated 90° clockwise.

To rotate the figure 90° clockwise about a point, every point (x,y) will rotate to (y, -x). Let's understand the rotation of 90° clockwise about a point visually. So, each point has to be rotated and new coordinates have to be found.

Now,

W (-4, 5)→W' (5, 4)

X (-1, 4)→X' (4, 1)

Y (-6, 1)→Y' (1, 6)

Z (-8, 3)→Z' (3, 8)

Therefore, the coordinates of the figure W'X'Y'Z' are W' (5, 4), X' (4, 1), Y' (1, 6) and Z' (3, 8).

Answer:

80 days

Step-by-step explanation:

Start off by making the two equations.

t = total cost

d = days

Robert Downey Jr.'s equation would be:

t = 8d

Chris Evans' equation would be:

t = 6d + 160

Now, set them equal to each other:

8d = 6d + 160

Then, solve for d:

8d = 6d + 160

Subtract 6d from both sides:

2d = 160

Divide both sides by 2:

d = 80 days

Answer:

The radius is multiplied by 5.

Step-by-step explanation:

The radius of the circle is multiplied by 5 times the radius of the old circle

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the radius of the old circle be r₁

Now , the area of the old circle A₁ = π( r₁ )²

And , let the radius of the new circle be r₂

where area of new circle = 5 x area of old circle

And , A₂ = 25A₁ = π( r₂ )²

On simplifying , we get

25A₁ / A₁ = π( r₂ )² / π( r₁ )²

( r₂ )² = 25( r₁ )²

On further simplification , we get

Taking square roots on both sides of the equation , we get

r₂ = 5r₁

Therefore , the value of r₂ = 5r₁

Hence , the new radius is 5 times the old radius of circle

Given:

Initial ice sheet's thickness = 2 meter

After 3 weeks, the ice sheet's thickness = 1.25 meters

To find:

The equation for the relationship between the thickness and number of weeks.

Solution:

Let y represent the ice sheet's thickness (in meters) after x weeks.

Initial ice sheet's thickness = 2 meter

It means, the equation of relation must be satisfy by the point (0,2).

After 3 weeks, the ice sheet's thickness = 1.25 meters

It means, the equation of relation must be satisfy by the point (3,1.25).

If a linear function passes through two points, then the equation is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-2=\dfrac{1.25-2}{3-0}(x-0)[/tex]

[tex]y-2=\dfrac{-0.75}{3}x[/tex]

[tex]y-2=-0.25x[/tex]

Add 2 on both sides.

[tex]y=-0.25x+2[/tex]

Therefore, the required equation for the given relation is [tex]y=-0.25x+2[/tex].
