How do you find the inverse of a function?

Ty is at Home Depot and must decide whether to buy paint in 10 individual quart cans or to buy it in both gallon and quart cans.

Ulleksa [173]

Find the cost of 4 quarts:

$ 6.99 [Cost of 1 quart] x 4 [Number of quarts] = $27.96 [Cost of 4 quarts]

Find the difference in price between 1 gallon and 4 quarts.

$ 27.96 [Cost of 4 quarts] - 20.99 [Cost of 1 gallon] = $ 6.97 [Difference]

One gallon of paint is less expensive than 4 quarts. The amount you save, $6.97, is just about the price of 1 quart of paint. When you buy the gallon, you get nearly 1 quart free.

Find out how many gallons to buy. Divide the total number of quarts needed by 4. This answer will tell Michael the number of gallons and quarts he needs.

10 ÷4 = 2 Gallons, 2 quarts

Two gallons and 2 quarts are equal to 10 quarts.

Find the cost.

$ 20.99 [Cost per gallon] x 2 = $41.98 [Cost of 2 gallons]

$ 6.99 [Cost per quart] x 2 = $13.98 [Cost of 2 quarts]

$ 41.98 [Cost of 2 gallons] + 1 3.98 [Cost of 2 quarts] = $ 55.96 [Total cost]

10 individual quarts cost $69.90 vs $55.96

So answer is C/2 gallons 2 quarts

A cooling tower for a nuclear reactor is to be constructed in the shape of a hyperboloid of one sheet. The diameter at the base

zaharov [31]

Okay so the equation you need to use is (x2/a2)+(y2/b2)-(z2/c2)=1

So an equation describing the shape of the tower in the coordinates where the origin is at the center of the narrowest part of the tower would be:

x^2 / 100^2 + y^2 / 100^2 – z^2 / 2 * 100^2 = 1

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corr

Vesnalui [34]

Answer:

Step-by-step explanation:

Given that the possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corresponding probabilities 0.15, 0.35, 0.35, and 0.15 respectively.

X 1 2 3 4

p 0.15 0.35 0.35 0.15 1

x*p 0.15 0.70 1.05 0.60 2.50

a)E(x) = 2.50

By linearity property

E(5-x) = 5-E(x) = 2.50

b) If fees it 75 then charges would be $75(2.5) = 187.50$

Else repair charges = $\frac{150}{E(5-x)} \\=60$

II one is better
