A cereal company's cost, in thousands of dollars, is represented by the function C(x)=2x+4500 and its revenue, in thousands of d
jekas [21]

Given , revenue function : R(x)= 5x

Cost function C(x) = 2x+4500

Profit  = Revenue - Cost

Hence, P = R(x) - C(x)

Total revenue for x = 12000 is R(12000) = 5(12000) = 60000

Total cost for x = 12000, C(12000) = 2(12000)+4500 = 28500

Profit = 60000-28500 = 31500

Answer = 31500

A dime is dropped from a building at a
Rasek [7]

Answer:

8 seconds

Step-by-step explanation:

Given :

h(t) = -16t2 + initial height

Initial height = 1024 feets

By the time it hits the ground, h(t) = 0

Equation becomes :

0 = - 16t² + 1024

Solve for t

-16t² = 1024

t² = 1024 / -16

t² = 64

t = √64

t = 8

Hence, it will take 8 seconds

What is the equation of the circle with center (4, 4) that passes through the point (10, 14)? HELP MEEEEE PLEASE
Gemiola [76]

Answer:

The equation of the circle can be written as:

  • \left(x-4\right)^2+\left(y-4\right)^2=136

Step-by-step explanation:

The general equation of a circle with center (h,k) and radius r is:

\left(x-h\right)^2+\left(y-k\right)^2=r^2

In our example, we know \left(h,k\right)=\left(4,4\right), as we just have to make sure we need determine \:r^2.

\left(x-4\right)^2+\left(y-4\right)^2=r^2\:\:

As the circle passes through (10, 14), that pair of values for x and y must satisfy the equation. So we have:

\left(10-4\right)^2+\left(14-4\right)^2=r^2

\mathrm{Switch\:sides}

r^2=\left(10-4\right)^2+\left(14-4\right)^2

r^2=6^2+10^2

r^2=36+100

r^2=136

Thus the equation of the circle can be written as:

\left(x-4\right)^2+\left(y-4\right)^2=136

What is a terminating decimal?
Arte-miy333 [17]
A terminating decimal has digits that end. They do not go on forever. For example, 0.125 has only 3 decimal digits and does not keep on going like 1/3



A rational number is a number that canbe expressed as p/q where p and q are both integers. But q cannot equal to 0.



All terminating decimals are rational numbers, but not all rational numbers are terminating decimals. For example 1/4, which equals to 0.25 is both a rational number and a terminating decimal. On the other hand, 1/3 is a rational number but is not a terminating decimal.
