A circle has a circumference of 50.24 units
What is the radius of the circle?

Answer:

-10

Step-by-step explanation:

x has to be less than -5. Since -10 is further away from 0 than any number it is the smallest. Also, -10 is more to the left.

7 to 8 = -15

8 to 9 = =17

x = 6

Explanation:

use the pythagorean theorem which is a^2 + b^2 = c^2. 8 goes in either the a or b position and 10 is the longest side so it will go in the c position.

Answer:

$57

Step-by-step explanation:

95*0.4=38

95-38

57

In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. the length of r, to the nearest 10th of an inch, is 365.9 Inches

Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.

a/Sin A = b/Sin B = c/Sin C

Where a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.

Hence,

58/Sin 19 = r/Sin 115

r = 58 Sin 115/ Sin 19

= 365.9 Inches

Therefore, In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. the length of r, to the nearest 10th of an inch, is 365.9 Inches.

Answer:

864 squared

Step-by-step explanation:

Answer:

This is a right angle triangle so

[tex] {hyp}^{2} = {opp}^{2} + {adj}^{2} [/tex]

[tex] {42}^{2} = a {}^{2} + 30 {}^{2} \\ 1764 = a {}^{2} + 900 \\ {a }^{2} = 1764 - 900 \\ a { }^{2} = 864 \\ a = \sqrt{864 } \\ a = 29.39[/tex]

Given:

A right triangle on a coordinate plane.

To find:

The area of a triangle.

Solution:

We know that, the area of a triangle is

[tex]A=\dfrac{1}{2}\times Base \times Height[/tex]

From the given figure it is clear that the base of the triangle is 4 units and the height is 3 units. So, the area of the given triangle is

[tex]A=\dfrac{1}{2}\times 4 \times 3[/tex]

[tex]A=\dfrac{12}{2}[/tex]

[tex]A=6[/tex]

The area of the given triangle is 6 units². Therefore, the correct option is B.

Answer:

The area of the given triangle is 6 units²

Spinner 2

Probability helps us to know the chances of an event occurring. Sam should use the second spinner.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that Sam plans to use a spinner to choose which friend to invite to the movies, he wants each friend to have a fair chance of being selected.

The term fair means that everyone or everything that is in the list should have equal opportunity.

Now, since Sam wants each friend to have a fair chance of being selected, therefore, the area on the spinner for each friend should be equal.

Hence, Sam should use the second spinner.

Answer:

I suppose we start with sin³(2*x) and we want to get:

(1/2)*sin(2*x)*(1 - cos(4*x))

Here we will use the relationships:

cos²(x) + sin²(x) = 1

and

cos²(x) = (1 + cos(2x))/2

Now let's start:

sin³(2*x) = sin(2*x)*sin²(2*x)

and we can write:

sin²(2*x) = 1 - cos²(2*x)

replacing that in the above equation we get:

sin³(2*x) = sin(2*x)*sin²(2*x) = sin(2*x)*(1 - cos²(2*x))

now we can use: cos²(2*x) =  (1 + cos(2*2*x))/2

cos²(2*x) =  (1 + cos(4*x))/2

if we replace that in the equation above we get:

sin³(2*x) = sin(2*x)*(1 - cos²(2*x)) = sin(2*x)*( 1 -  (1 + cos(4*x))/2)

sin³(2*x) = sin(2*x)*( 1 -  1/2 - cos(4*x)/2)

sin³(2*x) = sin(2*x)*( 1/2 - cos(4*x)/2)

sin³(2*x) = sin(2*x)*(  1 - cos(4*x))/2

sin³(2*x) = (1/2)*sin(2*x)*(  1 - cos(4*x))
