Answer:

h'(x) = -10x + 20

Step-by-step explanation:

To get the derivative of $ax^{n}$ , simply use the following formula:

$a(n)x^{n-1}$

We have the function, h(x) = -5x^2 + 20x

Using the formula, we get the derivative to be:

-10x + 20

so h'(x) = -10x + 20

John wants to buy a new laptop computer the computer store sells laptops for $480 or 9 credit payments of $58 how much interest

Neko [114]

First you would need to find out how many 9 payments of 58$ would be and that is 522. Then you would need to subtract the 522 and the 480 and your answer would be 42$ so the interest would be 42$

Which are the solutions of x2 = –7x – 8?

vovangra [49]

Answer:

The solutions are:

$x_1=\frac{-7+\sqrt{17}}{2}$ $x_2=\frac{-7-\sqrt{17}}{2}$

Step-by-step explanation:

We have the following quadratic equation

$x^2 = -7x - 8$

We can rewrite the equation as follows

$x^2+7x + 8=0$

Now we use the quadratic formula to solve the equation

For an equation of the form $ax ^ 2 + bx + c = 0$ the quadratic formula is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

In this case:

$a=1,\ b=7,\ c=8$

Then:

$x=\frac{-7\±\sqrt{7^2-4(1)(8)}}{2(1)}$

$x=\frac{-7\±\sqrt{49-32}}{2}$

$x=\frac{-7\±\sqrt{17}}{2}$

$x_1=\frac{-7+\sqrt{17}}{2}$

$x_2=\frac{-7-\sqrt{17}}{2}$

The height of a cylinder is 3 units. Its radius is 10 units. What is the volume of the cylinder, in cubic units? (Use π = 3.14)

serg [7]

The answer would be 942.
since the formula for volume of a cylinder is the area of the base times the height you would need to multiply pi times 10^2 and then times the height of 3.

3.14 * 10^2 = 314
314 * 3 = 942

I hope this helped :)
