Step-by-step explanation:
Let width and length be x and y respectively.
Perimeter (32in) =2x+2y=> 16=x+y => y=16-x
Area, A = xy = x(16-x) = 16x-x^2
The function to maximize is area: A=16 x-x^2
For maximum area, the first derivative of A =0 => A'=16-2x =0
Solving for x: 16-2x=0 =>2x=16 => x=8 in
And therefore, y=16-8 = 8 in
Step-by-step explanation:
The water level is 8 feet below your dock.
The tide goes out, and the water level lowers
2 foot. A storm surge comes in, and the
water level rises 3 feet. Write an addition
expression to find the new water level.
First, replace all variables with the given values.
12(9) + 9(2) + 2(12)
This should then equal 150, then the formula says to multiply this answer by 2. Doing so, should give a final answer of 300.
Let’s convert all their jumps into inches.
Breanna’s is already in inches (62)
Myquisha jumped 5 feet 4 inches
There are 12 inches in a foot, so
5 feet * 12 inches= 60 inches
Then add the 4 inches
60+4= 64
So Myquisha jumped 64 inches.
Ariana jumped 1 yard, 2 feet, 7 inches
1 yard is equal to 3 feet.
So, she jumped 5 feet 7 inches
12 inches in a foot, so
5*12=60 inches
Add the 7
60+7= 67 inches
So Breanna jumped 62, Myquisha 64 and Ariana 67
In order of shortest to longest:
Breanna, Myquisha, Ariana
