Hello there.
What is the height of the second rectangle?
12.
Answer:
11 feet wood will tenly use to make the frame.
Step-by-step explanation:
As given
Tey is making a square frame for her painting.
She is using 4 pieces of wood that are each 2.75 feet long.
Tenly uses wood to make the frame = Number of pieces of wood × Length of each pieces
Here
Number of pieces of wood = 4
Length of each pieces = 2.75 feet
Put in the above
Tenly uses wood to make the frame = 4 × 2.75
= 11 feet
Therefore 11 feet wood will tenly use to make the frame.

Answer
Step-by-step explanation:
You read the question and follow and like me.
<span>Ans : f(x)=xe^(-x^2/8)
differentiating by applying product rule,
f'(x)=x(e^(-x^2/8))((-2x)/8)+e^(-x^2/8)
f'(x)=e^(-x^2/8)(-x^2/4+1)
f'(x)=-1/4e^(-x^2/8)(x^2-4)
Now to find the absolute extrema of the function , that is continuous on a closed interval, we have to find the critical numbers that are in the interval and evaluate the function at the endpoints and at the critical numbers.
Now to find the critical numbers, solve for x for f'(x)=0.
-1/4e^(-x^2/8)(x^2-4)=0
x^2-4=0 , x=+-2
e^(-x^2/8)=0 ,</span>
