9. a company’s marginal cost function is where x is the number of units. find the total cost of producing units 144 to 625.

total cost is $2444

Step-by-step explanation:

A company’s marginal cost function is where x is the number of units

Marginal cost function is the derivative of cost function

to find the total cost of producing units , take integral of marginal cost function

with intervals 144 to 625

now plug in the values

total cost is $2444

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
