Answer: See explanation

Step-by-step explanation:

We are going to use the formula used in calculating direct proportion which is equal to:

y = kx

where,

x = speed of a processor in GHz

y = the cost in pounds

Therefore, y = kx

500 = 2k

Therefore, y = 2k

Dahasolnce [82]

I belive it is S=2C. Even if it was three years ago, if Sherman was twice as old then, then he would be twice as old now. So you can get rid of the three years ago. if someone is twice as old, it is the same as doubling it.

Angles C and D are acute angles of a right triangle.

Flauer [41]

Answer:

The answer to your question is cos C = $\frac{5}{7}$

Step-by-step explanation:

Data

sin D = $\frac{5}{7}$

Formula

sine Ф = $\frac{opposite side}{hypotenuse}$

- If sin D = $\frac{5}{7}$

the opposite side = 5

the hypotenuse = 7

- We can find the adjacent side of angle D using the pytagorean theorem

7² = a² + 5²

a² =49 - 25

a² = 24

a = $\sqrt{24}$

- To find the cosine of angle C

Cos C = $\frac{adjacent side}{hypotenuse}$

Cos C = $\frac{5}{7}$

<u> sin D = cos C</u>
