Let w= the length of the side perpendicular to the barn
300-2w= length of the side parallel to the barn
A=w(300-2w)
A=-2w^2+300w
The formula for the w-value of maximum is:
=-b/2a
thus our value will be:
300/4
=75
and
300-2(75)
=150
thus the dimensions to maximize the area is 75 by 150
Answer:
$3.33
Step-by-step explanation:
Divide 20 by 6
Answer:
the third one and the last one is correct
Step-by-step explanation:
we already know the second one is wrong because of it's set up.
just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)
Answer:
The complex numbers have opposite real numbers.
Answer:
Amy worked for 128 hours while Brayden worked for 112 hours
Step-by-step explanation:
Given
Let A represents Amy and B represents Brayden
A = 16 + B ------(1)
A:B = 8:7------- (2)
Required
Find A and B;
Convert (2) to fractions

Cross Multiply


Substitute A = 16 + B in the above expression

Open Bracket


Subtract 7B from both sides



Recall that A = 16 + B
Hence, 

<em>This implies that Amy worked for 128 hours while Brayden worked for 112 hours</em>
