A cylinder has a height h, and a radius (3h-2)

tekilochka [14]

Answer:

$V= 4\pi (9h^2 -12h + 4)$

Step-by-step explanation:

Given

Shape: Cylinder

$Radius = 3h - 2$

$Height = h$

$Base\ Area = \pi (3h - 2)^2$

Required

Simplify the volume

The volume is calculated as:

$Volume = Base\ Area * Height$

Substitute values for Base Area and Height

$V= \pi(3h-2)^2*h$

Expand the bracket

$V= \pi(3h-2)(3h-2)*h$

Open brackets

$V= \pi (9h^2 -6h - 6h + 4) *h$

$V= \pi (9h^2 -12h + 4) *h$

$V= 4\pi (9h^2 -12h + 4)$

Please help me i have a hw

aalyn [17]

Answer:

1.B 2.H 3. A

Step-by-step explanation:

1. First, find out the percentage of people who voted for Mathematika in survey one.

The total amount of people who voted is 14+17+19, which equals 50. 17/50 people voted for Mathematika, 17/50 = 0.34.

To find out how many people out of 300 will vote for Mathematika, multiply the 0.34 by 300. 300 x 0.34 = 102, so 102 people will vote for Mathetika.

2. You use the same logic for number 2. 14+17+19+20+19+11 = 100, so 100 people voted in total. 34 people voted for Infinitus. 34/100 = 0.34. Multiply 0.34 by 750 to get 255 people will vote for Infinitus.

3. The mean = the average. To find the average, add up all of the numbers, then divide that number by the amount of numbers added together.

7+9+11+13+15 = 55

5 numbers were added together so you divide 55 by 5

55/5 = 11. The mean is 11

9+10+11+12+13 = 55

There were 5 numbers added together

55/5 = 11. Both the means were the same

Evaluate g(p)•h(p) by modeling or by using the distribution property

Nataly [62]

$g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4$

Solution:

Given data:

$g(p)=(p-2)$ and $h(p)=\left(p^{3}+4 p^{2}-2\right)$

To find $g(p) \cdot h(p)$ :

$g(p) \cdot h(p)= (p-2)\cdot \left(p^{3}+4 p^{2}-2\right)$

Distributive property: $a(b+c)=ab + ac$

$= p\left(p^{3}+4 p^{2}-2\right) -2\left(p^{3}+4 p^{2}-2\right)$

$= \left(p^{4}+4 p^{3}-2p\right) +\left(-2p^{3}-8 p^{2}+4\right)$

$= p^{4}+4 p^{3}-2p-2p^{3}-8 p^{2}+4$

Arrange and add/subtract same powers.

$= p^{4}+(4 p^{3}-2p^{3})-8 p^{2}-2p+4$

$= p^{4}+2 p^{3}-8 p^{2}-2p+4$

Hence $g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4$
