Let
x ----------> the height of the whole poster
<span>y ----------> the </span>width<span> of the whole poster
</span>
We need
to minimize the area A=x*y
we know that
(x-4)*(y-2)=722
(y-2)=722/(x-4)
(y)=[722/(x-4)]+2
so
A(x)=x*y--------->A(x)=x*{[722/(x-4)]+2}
Need to minimize this function over x > 4
find the derivative------> A1 (x)
A1(x)=2*[8x²-8x-1428]/[(x-4)²]
for A1(x)=0
8x²-8x-1428=0
using a graph tool
gives x=13.87 in
(y)=[722/(x-4)]+2
y=[2x+714]/[x-4]-----> y=[2*13.87+714]/[13.87-4]-----> y=75.15 in
the answer is
<span>the dimensions of the poster will be
</span>the height of the whole poster is 13.87 in
the width of the whole poster is 75.15 in
Answer:
is there a diagram?
Step-by-step explanation:
Answer:
558 cm^3
Step-by-step explanation:
V cone = 1/3 pi r^2 h
We know it is 186 cm^3
186 =1/3 pi r^2 h
Multiply by 3
558 = pi r^2 h
V cylinder = pi r^2 h
From above we know that pi r^2 h is 558 , so the Volume of the cylinder is 558 cm^3
