i^22

(i²)^11

(-1)^11 ( NOTE: i² = -1 )

(-1)^(10+1)

(-1)^10 × (-1)^1

((-1)²)^5 × -1

1^5 × -1

-1

How do you factor a polynomial when one root has been given

zloy xaker [14]

So first what you are going to do is divide synthetically your root aka factor into your given equation. Then you are going to kind of guess ands check to find the other factor by synthetically dividing what you have left which should be
x^2 +2x +1 by -5, 5 (to make sure there is no multiplicity), 1, and -1 until you get zero in your remainder spot. The number you used to divide will be your other root.

According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 in

Zolol [24]

Answer:

The probability that the person is between 65 and 69 inches is 0.5403

Step-by-step explanation:

Mean height = $\mu = 66$

Standard deviation = $\sigma = 2.5$

We are supposed to find What is the probability that the person is between 65 and 69 inches i.e.P(65<x<69)

$Z=\frac{x-\mu}{\sigma}$

At x = 65

$Z=\frac{65-66}{2.5}$

Z=-0.4

Refer the z table for p value

P(x<65)=0.3446

At x = 69

$Z=\frac{69-66}{2.5}$

Z=1.2

P(x<69)=0.8849

So,P(65<x<69)=P(x<69)-P(x<65)=0.8849-0.3446=0.5403

Hence the probability that the person is between 65 and 69 inches is 0.5403

PLEASE PLEASE HELP ME OUT! But i ask that you explain how you got your answer and not just give the answer.

rjkz [21]

ok so first we would do the function d(x) = 3(8)+2

which when solved turns out to be 26

we would then do the function h(x) = 2(26) +7

which when solved turns out to be 59

so he would need 59 dollars for the donuts

A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.

marta [7]

Slope intercept form is y = mx + b

7 tickets for $5 means that 1 ticket costs 5/7 dollars

So for part a, the slope intercept form would be:

$y = \frac{5}{7}x$

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
$y = 25x$

where x is the number of all you can ride wristbands you buy, and y is the total price.

Henry packed some apples in a box. The total mass of the box and the apples was 16 240 g. He packed some strawberries in a simil

icang [17]

Step-by-step explanation:

x = mass of apples

y = mass of strawberries

z = mass of the box

x = 3y

x + z = 16240

y + z = 6350

let's subtract the second from the first equation

x + z = 16240

- y + z = 6350

-----------------------

x - y + 0 = 9890

using the first identity in that result gives us

3y - y = 9890

2y = 9890

y = 4,945 g

x = 3y = 3×4945 = 14,835 g = the mass of the apples
