Answer: 800 feet²
Step-by-step explanation:
Lets remove the brackets from the function's expression
A(x) = -2x²+80x
So we got the quadratic function and we have to find the x that corresponds to function's maximum. Let it be X max
As we know Xmax= (X1+X2)/2 , where X1 and X2 are the roots of the function A(x)
Lets find X1 and X2
x(80-2x)=0
x1=0 80-2*X2=0
x2=40
So Xmax= (0+40)/2=20
So Amax= A(20)= 20*(80-2*20)=20*40=800 feet²
Answer:C
Step-by-step explanation:
First club
y= 40 + 10x y= 40 + 10(8) =120
Second club
y= 15x y= 15(8) =120
now plug a number of the answer choices in each equation until you get the same result for both
The answer is C
Answer:
49 million if I'm not mistaken.
Step-by-step explanation:
The equations that represent the salary that Chloe's receive under the different options are:
1) Option 1: $600
2) Option 2: $ 350 + 8% * x, where x is the sales.
Using the fact that 8% = 0.08
Option 2 = $350 + 0.08x
A) If she has $3200 weekly salary:
Option 1 gives $600 (it is a constant salary)
Option 2 gives: $350 + $ 0.08 (3200) = $350 + $256 = 606.
Then, she will earn more money with the option 2.
B) The equation that can be used to determine when she earns more is found by making the two options equal:
Optio 1 = Option 2 =>
600 = 350 + 0.08x
C) Option 1 wiil lead to a greater earn when 600 > 350 + 0.08x
=> 600 - 350 > 0.08x
=> 250 > 0.08x
=> (250 / 0.08) > x
=> 3,125 > x => x < 3,125
Then, the answer is that she will earn more money with option 1 when x < 3,125
