Answer:
OCTAGON for question 1
Step-by-step explanation:
that's it an eight sided polygon is an octagon
B)-3 for the vertex, do u have to graph it?
Answer:
V(max) = 8712.07 in³
Dimensions:
x (side of the square base) = 16.33 in
girth = 65.32 in
height = 32.67 in
Step-by-step explanation:
Let
x = side of the square base
h = the height of the postal
Then according to problem statement we have:
girth = 4*x (perimeter of the base)
and
4* x + h = 98 (at the most) so h = 98 - 4x (1)
Then
V = x²*h
V = x²* ( 98 - 4x)
V(x) = 98*x² - 4x³
Taking dervatives (both menbers of the equation we have:
V´(x) = 196 x - 12 x² ⇒ V´(x) = 0
196x - 12x² = 0 first root of the equation x = 0
Then 196 -12x = 0 12x = 196 x = 196/12
x = 16,33 in ⇒ girth = 4 * (16.33) ⇒ girth = 65.32 in
and from equation (1)
y = 98 - 4x ⇒ y = 98 -4 (16,33)
y = 32.67 in
and maximun volume of a carton V is
V(max) = (16,33)²* 32,67
V(max) = 8712.07 in³
Answer:
Price for one pound = 50 cents
Step-by-step explanation:
Apples are on sale at the market 4 pounds for $2.00.
That is price for one pound = 0.5 $
We have 1 dollar = 100 cents
Price for one pound = 0.5 $ = 0.5 x 100 = 50 cents
Price for one pound = 50 cents
