8n = -3m + 1; n = -2, 2, 4

bogdanovich [222]

I am assuming you want to solve for m in each case

8n = -3m + 1

8(-2) = -3m + 1

-16 = -3m + 1

-3m = -17

m = $\frac{17}{3}$

8(2) = -3m + 1

16 = -3m + 1

-3m = 15

m = -5

8(4) = -3m + 1

32 = -3m + 1

-3m = 31

m = $\frac{31}{3}$

A tennis ball is in a cylindrical container. The ball has a radius of 5 inches and the cylinder has a height of 8 inches. How mu

Nostrana [21]

Answer:

104.7 in^3

Step-by-step explanation:

Step one:

given data

The ball has a radius of 5 inches and

the cylinder has a height of 8 inches

Step two:

The volume of the cylinder

$v= \pi r^2 h$

substitute our data

$v= 3.142*5^2*8\\\\v=628.4in^3$

The volume of the ball

$v=4/3 \pi r^3$

substitute our data

$v= 4/3 *3.142*5^3\\\\v= 523.7 in^3$

The space will have a volume of

=628.4-523.7

=104.7 in^3

(6u^2+5u^2v^2−3uv^2)−(4u^4+5u^2^v^2−5uv)

Aleksandr [31]

Answer:

$-4u^{4}+6u^{2}-5uv-3uv^{2}$

Step-by-step explanation:

When subtracting polynomials, first start with distributing the negative sign to the second polynomial:

$6u^{2} + 5u^{2} v^{2}-3uv^{2}-4u^{4}-5u^{2}v^{2}+5uv$

Simplify by combining like terms:

$-4u^{4}+6u^{2}-5uv-3uv^{2}$
