Answer:

exponential function, cool

Step-by-step explanation:

looks like f(x) = e ^x

So f(3) would be e^(3)

you can work this out on your calculator.

press [2ndf] [e^x]] [3] = 20

Best thing is draw a line up from x-axis to the curve, where it hits the curve you will have your answer

Car Rentals rents cars and trucks for $25 and $30 a

Sladkaya [172]

Answer:let x be the number of cars, and 7-x be the number of trucks.

25x + 30(7-x) = 195

25x + 210-30x = 195

5x = 15

x = 3

So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks

4 Trucks were not rented.

Which of the following are roots of the polynomial function?

Bingel [31]

Answer:

1 and -5

Step-by-step explanation:

$~~~~~x^3+3x^2-9x+5=0\\\\\implies x^3-x^2+4x^2-4x-5x+5=0\\\\\implies x^2(x-1)+4x(x-1)-5(x-1)=0\\\\\implies (x-1)(x^2 +4x -5) = 0\\\\\implies (x-1)(x^2+5x -x -5) = 0\\\\\implies (x-1)[x(x+5) -(x+5)] =0\\\\\implies (x-1)(x-1)(x+5)= 0\\\\\implies (x-1)^2(x+5) = 0\\\\\implies x = 1,~~ x = -5$

Given a circle with an area of 25 pi in^2 <br> What is the exact circumference?

Taya2010 [7]

Answer:

31.4

Step-by-step explanation:

C = 2πr OR C = πd

But, we need to find r first.

$A = \pi r^2\\25\pi = \pi r^2\\\sqrt{25} = \sqrt{r^2} \\r=5\\\\C=2\pi r\\C=2\pi (5)\\C= 10\pi \\C= 31.4$
