2 W + 5 L = 750 ft
5 L = 750 - 2 W
L = 150 - 2 W / 5
A ( W ) = W * ( 150 - 2 W / 5 )
A function that models the total area:
A ( W ) = 150 W - 2 W² / 5
A` ( W ) = 150 - 4 W / 5
150 - 4 W / 5 = 0
4 W / 5 = 150
W = 187.5 ft
The largest possible area:
A = 150 * 187.5 - (2 * 187.5² ) / 5 = 28,125 - 14,062.5 = 14,062.5 ft²
Remember this! The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.
Answer:
f(x)= 3x-8,
f(x)=-17
so
-17 = 3x -8
3x= -17+8
3x = -9
x =-3
Step-by-step explanation:
The result of the exponential expression is 81
<h3>Indices expressions</h3>
Indices are written in term of exponents
According to the expoenent law of indices
a^4 = a * a * a * a
Given the expression
(-3)^4
This means the product of -3 in four places. Mathematically
(-3)^4 = -3 * -3 * -3 * -3
(-3)^4 = 9 * 9
(-3)^4 = 81
Hence the result of the exponential expression is 81
