The numbers are increasing by positive 10 each time. So the rate of change is 10.
Answer:
C
Step-by-step explanation:
Note that <em>x</em> is opposite to the given angle and we are also given the hypotenuse.
Since we have an angle and the side opposite to it and the hypotenuse, we can use the sine ratio. Recall that:

The opposite side is <em>x</em>, the hypotenuse is 15, and the angle is 53. Substitute:

Solve for <em>x: </em>

Use a calculator (make sure you're in Degrees Mode!). Hence:

Our answer is C.
It's a, because an exponent means it's multiplied by itself that many times. so 3 times 3 is 9 then times 3 again is 27. but negative exponents are always fractions and since the normal number is positive it's D (sorry at first I didn't see d and c)
Answer:
C: 200
Step-by-step explanation:
Just multiply 12.5 x 8 x 2 to get the answer.
I think that the answers are 4, 4 and 25 respectively
