Answer: -1 and 1

Step-by-step explanation:

i gotchu, no worries!

first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)

then, evaluate it.

x^2 - 9 = -2^3

next, move the constant to the right.

x^2 - 9 = -8

next, calculate it.

x^2 = -8 + 9

simplify it.

x^2 = 1

finally separate the solutions.

x = 1

x = -1

Can a triangle be formed if the side<br> lengths are 10, 23, and 10?
FinnZ [79.3K]

Answer:

No.

Step-by-step explanation:

No, because 23 > 10 + 10.

If any side is equal or greater than the sum of the other 2 sides no triangle can be drawn.

PLEASE HELP!! I need this completed ASAP but I don't understand any of it!! It's due very soon!
lidiya [134]

Answer:

Step-by-step explanation:

a) you know interest is 22 and principal is 1000 and number of months is 1

b) I = rPm

   r = I/Pm

c) r = 22 / 1000(1) = 0.022 /month or 2.2% per month

or 12(0.022) = 0.264 or 26.4 % per year.

d) interest is $15, loan period is 2 weeks which occurs once during the loan, interest rate is 10% per two weeks.

P = I/rm

e) P = 15 / 0.10 = $150

Notice that there are 52 weeks/yr / 2week loan period = 26 period in a year.

This means that the APR is 0.10(26) = 2.60 or 260% annual interest rate. Pretty good return on investment if you are the lender and can keep your money lent out. Not so good if you are the borrower.

In a batch of 440 water purifiers, 8 were found to be defective. What is the probability that a water purifier chosen at random
LiRa [457]

Answer:

1.8% or 1.818181%

Step-by-step explanation:

If in a batch of 440 water purifiers, we find 8 to be defective.

Then the probability of the next purifier being defective is 8/440

In percentage = 8/440 * 100

=> 8/44 * 10

=> 8/22 * 5

=> 40/22

=> 20 / 11

20/11 is roughly 1.8181818

Rounding it to the nearest tenth, we get 1.8%

If my answer helped, kindly mark me as the brainliest!!

Thank You!!
