If y varies directly as the x^2 and y = 200 when x = 5, what is the value of y when x = -3?
gayaneshka [121]
As the variation is direct we have:
 y = kx ^ 2

 We must find the value of k.
 For this, we use the following data:
 y = 200 when x = 5
 Substituting values we have:
 200 = k5 ^ 2

 Clearing k:
 k = 200/5 ^ 2

k = 200/25

k = 8
 Then, the function is:
 y = 8x ^ 2

 We evaluate the function for x = -3
 y = 8 (-3) ^ 2

y = 8 (9)

y = 72
 Answer:
 the value of y when x = -3 is:
 c.

Which expression is equivalent to 7h^2-252k^2?
gulaghasi [49]

Answer:

c

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b²  = (a + b)(a - b)

7h² - 252k² =  7(h² - 36k²)

                   = 7(h² - [6k]² )

                  = 7(h  +6k)(h - 6k)

Which is bigger 2/5 or 4/9
Jlenok [28]
The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.

2/5 = 18/45
4/9 = 20/45

Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
