Answer:

Step-by-step explanation:

The squaring function x^2 and the square root function √x are inverses of one another. Because of this, the square of the square root of a number is the number itself: [√x]^2; this is identical to √[ x^(1/2) ]^2 = x^(2/2) = x^1.

If we are given the square root of a number, then the number itself is the square of the given square root.

Example: Given x with the info that x is the square root of a number, then the square of that x is x^2.

A quadratic function has zeros at 1 and -8. Which of the following could be the function?

3241004551 [841]

Answer:(x-1)(x+8)

Step-by-step explanation: You need to set it up as (x+y)(x+z) format. To get that you need to flip the zeroes making them the opposite. So the answer in this case would be (x-1)(x+8).

The number 1.3,1/1/3,1.34 in least to greatest

elixir [45]

1.3, 1 1/3, 1.34

The decimal version of 1 1/3 is 1.333 (so on)

so 1.3 is less than 1.333 and 1.333 is less than 1.34

1.3<1.333<1.34

Write an exponential equation that represents the given situation. You invest $1000 and it increases 12% each year. Can you teac

IrinaK [193]

Answer:

FV= 1,000*(1.12^n)

Step-by-step explanation:

Giving the following information:

Initial investment= $1,000

Increase rate= 12% = 0.12

We need to formulate an exponential equation to show the value in n years.

To calculate the Future Value, we need to use the following formula:

FV= PV*(1+i)^n

Being:

FV= Future Value

PV= Initial Investment

i= increase rate

n= number of periods

FV= 1,000*(1.12^n)

For example, for one year:

FV= 1,000*(1.12^1)

FV= $1,120

For 3 years:

FV= 1,000*(1.12^3)

FV= $1,404.93
