5x2/11. how do i find simplest form
adelina 88 [10]
Assuming you are multiplying 5 times 2/11 then you just put 5/1 because anything divided by 1 is still one, and then multiply 5/1 by 2/11. Meaning, 5 times 2 is 10. And 1 times 11 is 11. So it would be 2/11. You multiply the numerators(top number) and denominators(bottom number). 2/11 is already simplified

A=130(1.05)^x by what percent does the balence increase each year?
frosja888 [35]

Answer:

5%

Step-by-step explanation:

The question showing a growing function that commonly used in compound interest calculation. The formula for compound interest is:

A = P (1 +r) ^ t

A= amount of the balance after a period of t

P= principal, the initial money deposit

r= rate

t= time

The percent of balance increase should be represented by the rate(r). In this equation, the principal will be 130, (1+r) will be 1.05, and time will be x.

The value of rate (r) will be:

(1+r) = 1.05

r= 1.05-1= 0.05 = 5%

PLEASE HELP ITS AN EMERGENCYYYYYYYYYY!!!
lorasvet [3.4K]

Answer:

The value of k is 1.

Step-by-step explanation:

x – 1 is a factor of f(x)

This means that:

x - 1 = 0

x = 1

That means that when x = 1, y = 0. We use this to find the value of k.

f(x) = 3x^3 - 4x + k

3*1^3 - 4(1) + k = 0

3 - 4 + k = 0

k = 1

The value of k is 1.

Find the slope of the line that passes through the ordered pairs (-2,8) and (-9,19)
Ilia_Sergeevich [38]

Answer:

slope: -11/7

Step-by-step explanation:

Slope is equal to the change in yy over the change in xx, or rise over run.

m=change in ychange in xm=change in ychange in x

The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).

m=y2−y1x2−x1m=y2-y1x2-x1

Substitute in the values of xx and yy into the equation to find the slope.

m=19−(8)−9−(−2)m=19-(8)-9-(-2)

Simplify.

m=−11/7
