89
Step-by-step explanation:
Just add the numbers, put them into the formula, and then divide. SO EASY!!!
The volume of a pyramid is
V=(l*w*h)/3=(35*4)/3=140/3=46.67 cubic feet , choice C
Answer:
y=6
Step-by-step explanation:
Differentiate the equation
dy/dx=2x-8
Find the value of x in equation form
2x-8=0
x=8/2=4
Now x=4 is the line of symmetry or the parabola of the quadratic equation.
Plug back x=4 into the equation to find the turning point(minimum value)
y=(4)²-8(4)+22
y=16-32+22
y=6
Height x Width = Area
Area divided by height = Width
31.5 divided by 6.3 = 5ft
