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

Officer Brimberry wrote 24 tickets for traffic violations last week, but only 15 tickets this week. What is the percent decrease

frosja888 [35]

Answer:

%37,5

Step-by-step explanation:

Last week = 24 Tickets

This week = 15 Tickets

Decrease = 24 - 15 = 9 Tickets

We should calculate the percentage of 9 in 24

Let's say %100 percentage is 24

İf 100 percentage is 24

Then X percentage is 9

100 * 9 = 24 * X

900 = 24 * X

900 / 24 = X

37,5 = X -----> It is the percentage of decrease

A window is 12 feet above the ground. A ladder is placed on the ground to reach the window. If the bottom of the ladder is place

murzikaleks [220]

You will need to use Pythagorean theorem a^2 + b^2 = c^2
the a and b values will be 12 and 5 feet. So just plug them in and solve for c.
12^2 + 5^2 = c^2
144 + 25 = c^2
169 = c^2 square root both sides
13 = c
so the ladder has a length of 13 feet.
