To find the mean, or average, we add up all the numbers to get the total number of siblings (16), and divide by the number of classmates she surveyed (12). 16/12 = 1.3

Please LMK if you have questions. Have a good day.

Can you help me!!!!!!!!

Answer:

Yes, this is A Linear Function!

Step-by-step explanation:

This is a linear function beacuse linear functions are straight lines on the graph as you may know. So when we graph these numbers it turns up as a straight increasing linear line.

If the length of a pool is 8 more than twice the width and the total area is 960 square feet, find the length and width of the r

melomori [17]

Answer:

l=48, w=20

Step-by-step explanation:

Let the width of the pool be w feet, then the length will be:

$l = 2w + 8$

The area of the pool is 960 square feet.

This means that:

$w(2w + 8) = 960$

Expand and rewrite in standard form to get:

$2 {w}^{2} + 8w - 960 = 0$

${w}^{2} + 4w - 480 = 0$

${w}^{2} + 24w - 20w- 480 = 0$

${w}(w+ 24) - 20(w + 24) = 0$

Factor to get:

$(w+ 24)(w - 20) = 0$

$w = - 24 \: or \: w = 20$

We discard the negative value because magnitude is positive.

This means

$l = 2 \times 20 + 8 = 48$

If your accelerator suddenly gets stuck what should you avoid doing?

Vika [28.1K]

I guess you should not break. The friction heats up the pads and drum and could start a fire.
Put into neutral, have the emergency lights on, blink other drivers and when possible pull off to safety.
Also you should not JUMP... .

If (3-4i) (x+yi) = 1 + 0i. The value of x and y is

Black_prince [1.1K]

Step-by-step explanation:

$\textsf{\large{\underline{Solution}:}}$

<h3><u>Given That:</u></h3>

$\rm: \longmapsto (3 - 4i)(x + iy) = 1 + 0i$

$\rm: \longmapsto 3(x + iy) - 4i(x + iy)= 1 + 0i$

$\rm: \longmapsto 3x + 3iy - 4ix +4y= 1 + 0i$

<u>On rearranging the terms, we get:</u>

$\rm: \longmapsto (3x + 4y)+ (3y - 4x)i = 1 + 0i$

<u>Comparing both sides, we get:</u>

$\rm: \longmapsto 3x + 4y = 1 --- (i)$

$\rm: \longmapsto 3y - 4x = 0 --- (ii)$

<u>Multiplying (i) by 4, we get:</u>

$\rm: \longmapsto 12x + 16y = 4--- (iii)$

<u>Multiplying (ii) by 3, we get:</u>

$\rm: \longmapsto 9y - 12x = 0 --- (iv)$

<u>Adding equations (iii) and (iv), we get:</u>

$\rm: \longmapsto25y = 4$

$\rm: \longmapsto y =\dfrac{4}{25}$

<u>From (ii), we get:</u>

$\rm: \longmapsto 3y - 4x = 0$

$\rm: \longmapsto 3y = 4x$

$\rm: \longmapsto x = \dfrac{3}{4} y$

$\rm: \longmapsto x = \dfrac{3}{4} \times \dfrac{4}{25}$

$\rm: \longmapsto x = \dfrac{3}{25}$

<u>Therefore:</u>

$\rm: \longmapsto (x,y)= \bigg( \dfrac{3}{25}, \dfrac{4}{25} \bigg)$

★ <u>Which is our required answer.</u>

$\textsf{\large{\underline{More To Know}:}}$

$\rm1.\ i^{4n} = 1$

$\rm2. \ i^{4n+1} = i$

$\rm3.\ i^{4n+2} = -1$

$\rm4.\ i^{4n+3} = -i$
