If it is:

(-2)^2 = 4

If it is:

-(2)^2 = -4

We use math everyday in every way. Your brain uses math just to brush your teeth! :)

idk

You get two chances of getting 6, which is already 1/6, You have a 1/3 chance of at least rolling a 6

Portia has 9 more pennies than quarters. Altogether she has 2.95 in pennies and quarters. How many of each coin does Portia have.

Let the number of quarters =Q

Number of pennies =Q +9

0.25Q + 0.01[Q + 9] =2.95, solve for Q

0.25Q + 0.01Q + 0.09=2.95

0.26Q =2.86 divide both sides by 0.26

Q =2.86 / 0.26

Q =11 Number of quarters

11 + 9 =20 Number of pennies. So that:

[11 x 0.25] + 0.20 =$2.95

No -2^2 does not equal 2i, the square root of -2 is 2i. This if you are not in algebra 2 yet is because they made up a number that is equal to the square root of -1=i. -2 squared however is just positive 2.

FV = PV[1 + R]^N

FV = 15,000 x [ 1+ 0.06/365]^(3*365)

FV = 15,000 x [1 + 0.00016438356]^1,095

FV = 15,000 x        1.19719965....

FV =$17,957.99

2+2*5-545+965*55/3-5+8*45/33-0=

if x is the length of the rectangle and y is the width of the rectangle then:

x = 2y + 3.

Then you are able to say:

2x + 2y = 48.

Substituting x and simplifying, we get:

6y + 6 = 48. Or

y = 7.

Then we can figure out x:

x = 2*7 + 3 = 17.

So, the final answer is:

Length = 17.

Width = 7.

I assume this to be a loan of $22,395 to be paid off in 72 months, or 6 years, at $440 per month. If this is correct, then you have to use this formula to find the interest rate:

PV=P{[1 + R]^N - 1.[1 + R]^-N} R^-1

22,395 =440 x {[1+R]^72 -1 x [1+R]^-72} x R^-1

It turns out that there is no direct solution using logs. However, the computers are programmed to use iterations and interpolation to find the interest rate R.

So, the computer comes out with a rate of: 12.19% compounded monthly.

This happens alot. dont worry. Who is Mekenzie.

try multiplying .35 by 60 c;

thank you you think you can help me some more ?
