Answer:
(0.5,0)
Step-by-step explanation:
The line of symmetry is if you drew a line straight down the middle (vertically) of the parabola and where it would hit the x-axis
The volume of a rectangular box is equal to the area of its base times the vertical height. Thus,
V = Ah = 80
Since the base is a square with side x, then the area is equal to x². Hence, we can express h in terms of x.
80 = x²h
h = 80/x²
Now, each lateral side of the rectangular box is in the shape of a rectangle with a length of h and a width of w. Hence, the equation for the total cost would be:
Total Cost = Cost per area of lower base + Cost per area of upper base + 4(Cost per area of lateral side)
Total Cost = 0.45x² + 0.28x² + 4(0.10h*x)
Total Cost = 0.73x² + 0.4hx
Since h = 80/x²,
Total Cost = 0.73x² + 0.4(80/x²)(x)
Total Cost ($) = 0.73x² +32/x
Answer:which one..?
Step-by-step explanation:
1/8 is the answer when you subtract 4/8from 5/8
Answer:
question 1 aca the one with an area of 6 answer: B=5.
question2 answer: B=14
Step-by-step explanation:
Question 1- to set up question 1 do 1.2(B)=6. Then divide both sides by 1.2. The side that is 1.2(B)/1.2 will cancel out so it will now just be B. the side that = 6 will be divided by 1.2=5. So the answer is B=5.
Question 2- to set up the problem do 0.5(B)=7. Then divide both sides by 0.5. The side that reads 0.5(B)/0.5 will cancel out so it will not just be B. the other side that reads =7 will be divided by 0.5= 14 giving you B=14.
