An aquarium wants to install a new fish tank with a parabolic glass dome fitted at its bottom to allow visitors to look at the marine life from below. The glass dome will be 60 feet in diameter and will have a depth of 4 feet. Find the equation of the parabolic cross-section of the dome.
y2 = 16/30(x)
y2 = 4/15(x)
y = 1/225(x^2)
y = 15/14(x^2)
y = 1/15(x^2)

3 ft = 1 yd
96/3 = 32
Answer: 32 yds
Answer:
A positive 3x
Step-by-step explanation:
since both parts have the same variable you could add them or subtract them together
(3x-7x)+(3x+4x)
You will subtract 3x-7x which will give you a negative 4x
You will do the same on the other side
Add 3x+4x and it will give you a positive 7x
-4x+7x=will give you an positive 3x

Answer:
The answer is "8 hours"
Step-by-step explanation:
by the given value we create the equation that is:
![\to 45x-40=300\\\\\to 45x=300+40\\\\\to 45x=340\\\\\to x=\frac{340}{45}\\\\\to x= 7.55\ \ hours \ or \ \ \ 8 \ hours](https://tex.z-dn.net/?f=%5Cto%2045x-40%3D300%5C%5C%5C%5C%5Cto%2045x%3D300%2B40%5C%5C%5C%5C%5Cto%2045x%3D340%5C%5C%5C%5C%5Cto%20x%3D%5Cfrac%7B340%7D%7B45%7D%5C%5C%5C%5C%5Cto%20x%3D%207.55%5C%20%5C%20hours%20%5C%20or%20%5C%20%5C%20%5C%208%20%5C%20hours)
