Answer:

check 2nd and last box. :))

Step-by-step explanation:

Ok, so I would work out the Area, then rule out a few of these options.

First of all, if you look closely, you can see that instead of an l(x), it's an l(w), which means that what l(w) equals, is a product of whatever l(x) is with w serving as its x (if that makes sense lol). so, we need to divide by w to figure out what l(x) is.

<u>3x³+2x²-4x+5</u>  <u>(3x³+5)+(2x²-4)</u> <u>(3x³+5)+2(x+2)(x-2)</u><difference of two squares

      x+2         ⇒      x+2          ⇒         x+2                  so then the (x+2)'s cancel

and you're left with 3x³+5+2x-4 ⇒ 3x³+2x+1 which is l(x). Now you're ready to see what A(x) equals.

x(3x³+2x+1)+2(3x³+2x+1) =

[(3x^4)+2x²+x]+(6x³+4x+2) =

(3x^4)+6x³+2x²+5x+2=A(x)

So now you can rule out the answers. <u>Number one</u> can be done mentally, and it's <u>not correct</u>. <em><u>Number 2 is definitely true</u></em>. Number three we need to work out.

<u>(3x^4)+6x³+2x²+5x+2</u>     <u>[(3x^4)+6x³]</u> (the rest doesn't matter)⇒ <u>3x³</u><u>(x+2)</u>

             x+2                ⇒                                                                    x+2

So then you're left with 3x³+2x²+5x+2 which is<em> not</em> equal to l(x), so the third option is false and ruled out. The <u>fourth one</u> you can just look at A(x) and conclude <u>it's false</u>, and the <u>third one is very obviously true</u>.

zoey made 5 1/2 cups of trail mix for a camping trip. she wants to divide the trail mix into 3/4 cup servings. ten people are go
Andreas93 [3]
A.) Number of 3/4 cup servings in 5 1/2 cups = 5 1/2 / 3/4 = 11/2 / 3/4 = 11/2 x 4/3 = 44/6 = 7 1/3
Therefore, Zoey did not make enough 3/4 cup serving to go round everybody.

b.) For, every one to have a serving, we have 5 1/2 cups which we want to go round ten people, so each person should get 5 1/2 / 10 = 11/2 / 10 = 11/2 x 1/10 = 11/20.
So the serving should be 11/20 cup for every one to get serving.

c.) If she uses the 3/4 cup serving, then she will need 3/4 x 10 = 30/4 = 7 1/2 cups altogether.
Therefore, she will need to make extra 7 1/2 - 5 1/2 = 2 cups of trail mix.

HELPP ASAP I WILL GIVE 14 POINTS
jek_recluse [69]

Given:

A box-and-whisker plot of data set.

To find:

The percentage of the data values that are greater than 80.

Solution:

From the given box-and-whisker plot, it is clear that:

Minimum value = 8

First quartile = 60

Median = 68

Third quartile = 80

Maximum value = 92

We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.

Therefore, about 25% of the data values that are greater than 80.

Help please I don’t know the answer
icang [17]

Answer:

$16,534.95

Step-by-step explanation:

To compute interest on loans, we use the compounded interest equation. We use the equation A=P(1+\frac{r}{n})^{nt} where

  • P is the principle or starting value
  • A is the total amount after interest and a period of time
  • r is the rate at which interest gathers as a decimal
  • t the time in years
  • n is the number of times compounded in a year.

For this problem, we know P=$8000, r=19%=0.19, t=4 years and n=2. We substitute into the formula and simplify to find the total amount A.

A=P(1+\frac{r}{n})^{nt}\\A=8000(1+\frac{0.19}{2})^{2(4)}\\A=8000(1+0.095)^{8}\\A=16,534.95
