Problem 1

Answer:

  1. The square root of the <u>   expression   </u> of the <u>   difference   </u> of <u>   x^2   </u>  and 11.
  2. The <u>   quotient   </u> of <u>   2   </u> times a number and -1
  3. The <u>   sum   </u> of the <u>   square root   </u>of two times a number and 11.

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

Explanation:

The term "difference" is the result of subtraction. We're subtracting the x^2 and 11. Then applying the square root to the result.

Question 2 has the blanks filled correctly.

For the last sentence, we have a sum of the terms \sqrt{2x} and 11.

===========================================================

Problem 2

Answer:

The value of an algebraic expression depends on its <u>   variables   </u>

  1. Substitute the known value for each variable.
  2. Simplify using the <u>   order   </u> of <u>   operations   </u>
  3. Use the work to answer any word problems related to the expression.

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

Explanation:

The variables are placeholders for numbers

So for instance, saying x+5 is like saying "some unknown number plus 5".

We could replace it with something like x = 10 to get x+5 = 10+5 = 15

Once the variable is replaced, you use the order of operations PEMDAS (some books refer to it as BODMAS).

The inequality written in interval notation is therefore -4<x<-1  or (-4, -1)

<h3 /><h3>What are inequalities?</h3>

Inequalities are expressions separated by the mathematical inequalities ≤, ≥, < and >

For instance a < b is a form of inequality.

<h3>What is a number line?</h3>

A number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.

From the given number line, we can see that closed circles are on -4 and -1. The inequality written in interval notation is therefore -4<x<-1  or (-4, -1)

Hector invests $20,000 at age 21. He hopes the investment will be worth $200,000 when he turns 40. If the interest compounds con
KiRa [710]

Answer:

12.12%

Step-by-step explanation:

We have that the formula is given by:

A = p * e ^ (r * t)

From here, we know that A = 200000; p = 20000 and the time we can calculate 40 - 21 = 19

if we replace we have:

200000 = 20000 * e ^ (19 * r)

we must calculate r:

e ^ (19 * r) = 200000/20000

e ^ (19 * r) = 10

19 * r = ln 10

r = ln 10/19

r = 0.1212

In other words, the rate of growth is 12.12%
