The figures are similar. Find the value of the variable. A) y=36
Dovator [93]

Answer:

D y= 81

Step-by-step explanation:

Since the triangles are similar, the ratios of similar sides must be equal.

30/54 = 45/ y

We can use cross products

45*54 = 30*y

2430=30y

Divide each side by 30

2430/30 = 30y/30

81 =y

Evaluate the function at each specified value of the independent variable and simplify. (if an answer is undefined, enter undefi
tekilochka [14]

For this case we have the following function:

h (t) = t ^ 2 - 8t

What we should do is evaluate the function for the different values of the independent variable.

We have then:

For x = 8:

h (8) = (8) ^ 2 - 8 (8)

h (8) = 64 - 64

h (8) = 0

For x = 1.8:

h (1.8) = (1.8) ^ 2 - 8 (1.8)

h (1.8) = 3.24 - 14.4

h (1.8) = -11.16

For x = x + 8:

h (x + 8) = (x + 8) ^ 2 - 8 (x + 8)

h (x + 8) = x ^ 2 + 16x + 64-8x-64

h (x + 8) = x ^ 2 + 18x

Answer:

The results of evaluating the function are:

h (8) = 0

h (1.8) = -11.16

h (x + 8) = x ^ 2 + 18x
