Find the product and simplify your answer. -n(-2n4+9n-5)

Harman [31]

Answer:

$+2n^5 - 9n^2 + 5n$

Step-by-step explanation:

To solve the expression

$-n(-2n^4+9n-5)$

first we will multiply -n with each term and then find their products.

When doing multiplication the powers will be added and co-efficient will be multiplied.

$-n(-2n^4+9n-5)\\-n(-2n^4) -n(+9n) -n(-5)\\+2n^5 - 9n^2 + 5n$

A Web music store offers two versions of a popular song. The size of the standard version is 2.9 megabytes (MB). The size of the

GrogVix [38]

s +h = 1070 ( total number of downloads)

Rewrite as s =1070 - h

2.9s + 4.4h = 4393 ( total download size)

Substitute:

2.9(1070-h) + 4.4h = 4393

Simplify:

3103 - 2.9h + 4.4h = 4393

Combine like terms:

3103 + 1.5h = 4393

Subtract 3103 from each side:

1.5h = 1290

Divide both sides by 1.5:

h = 1290 / 1.5

h = 860

Replace h with 860 in first equation to solve for s:

s + 860 = 1070

s = 1070 - 860

s = 210

There were 210 standard downloads and 860 high quality downloads

Help with this question please!

vova2212 [387]

V = 120 in^3

Here is why:

The volume formula for a pyramid is:

$V=\frac{1}{3}Bh$

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:

$A=\frac{1}{2}bh$

Plug in the numbers.

$A=\frac{1}{2}*9*10$

A = 45

Now we have found the area of B, we can plug it into the volume formula for the pyramid.

$V=\frac{1}{3}*45*8$

V = 120 in^3
