Acompany manufacturers fuel tanks for automobiles. the total weekly cost (in dollars) of producing x tanks is given by c(x) = 10,000 + 90x- 0.05x^2
-find the marginal cost function

-find the marginal cost at a production level of 500 tanks per week and interpret the results

-find the exact cost of producing the 501st item

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
