Answer:

see below

Step-by-step explanation:

we are given a exponential function

$\displaystyle y = \left(1/5\right) ^{x}$

we want to figure out the missing values of y for x i.e (-2,-1, and 2) to do we can consider substituting so,

when x is -2 y should be

$\displaystyle y = \left(1/5\right) ^{ - 2}$

rewrite ⅕ in exponent notation:

$\displaystyle y = \left((5) ^{ - 1} \right) ^{ - 2}$

by law of exponent we obtain:

$\displaystyle y = (5) ^{ 2}$

simplify square:

$\displaystyle y = \boxed{ 25}$

when x is -1:

$\displaystyle y = \left(1/5\right) ^{ - 1}$

rewrite ⅕ in exponent notation:

$\displaystyle y = \left((5) ^{ - 1} \right) ^{ - 1}$

use law of exponent which yields:

$\displaystyle y = \boxed5$

when x is 3:

$\displaystyle y = \left(1/5\right) ^{ 3}$

by law of exponent we obtain:

$\displaystyle y = 1/ {5}^{3}$

simplify square which yields:

$\displaystyle y = \frac{1}{ \boxed{125}}$

The perimeter of a standard basketball court is 288 ft. Find the dimensions of the basket ball court if its length is 44 longer

Vinil7 [7]

Answer:

w = 50, l = 94

Step-by-step explanation:

l = w + 44, to find perimeter we need 2l + 2w = 288 and we know l so substitute 2(w+44) + 2w = 288, so 2w + 88 + 2w = 288 so 4w = 200, therefore w = 50
