8 is the answer because when you add 11+4 you get 16 and then you would subtract that from 24 which would give you 8. Idk where you got "PA" ?
162 / 2 = 81
the answer is D
Answer: Distributive because 6 has to be multiplied by x and 7
Answer:
Step-by-step explanation:
Given that a rectangle is inscribed with its base on the x-axis and its upper corners on the parabola

the parabola is open down with vertex at (0,2)
We can find that the rectangle also will be symmetrical about y axis.
Let the vertices on x axis by (p,0) and (-p,0)
Then other two vertices would be (p,2-p^2) (-p,2-p^2) because the vertices lie on the parabola and satisfy the parabola equation
Now width = 
Area = l*w = 
Use derivative test
I derivative = 
II derivative = 
Equate I derivative to 0 and consider positive value only since we want maximum
p = 
Thus width= 
Length =
Width = 
Model of Statue of Liberty is 30.6 feet tall.
<u>Step-by-step explanation:</u>
Given the Statue of Liberty is 306 feet tall. If the model is 1/10 the actual size of the Statue of Liberty.
Actual size of the statue = 306
Model is
of the actual size of the Statue of Liberty
Height of model =
of the actual size
=
* 306
= 30.6 feet
Model of Statue of Liberty is 30.6 feet tall.
