babunello [35]

F(x) = x^2 - x + 2
f(x) = x^2 - x + 1/4 + 2 - 1/4
f(x) = (x - 1/2)^2 + 7/4
Therefore, vertex = (1/2, 7/4)

A company rents water tanks shaped like cylinders. Each tank has a diameter of 8 feet and a height of 3 feet. The cost is $5 per

BARSIC [14]

Answer:

$754.05

Step-by-step explanation:

We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.

The volume of a cylinder is:

$V = \pi r^2h$

where r = radius

h = height

Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.

The volume of the tank is therefore:

$V = \pi * 4^2 * 3 = 150.81 ft^3$

The cost of renting is $5 per cubic foot.

Therefore, the cost of renting a tank is:

150.81 * 5 = $754.05

It costs $754.05 to rent a tank.

madreJ [45]

Answer:

Fast train speed: 69 km/h

Slow train speed: 39 km/h

Step-by-step explanation:

Fast train:

-Time: 4.33

-Speed: x

-Distance: 4.33x

Slow train:

-Time: 7.66

-Speed: x - 30

-Distance: 7.66(x - 30)

7.66(x - 30) = 4.33x

7.66x - 229.8 = 4.33x

3.33x = 229.8

x = 69
