[tex]6\sqrt{32} - 12\sqrt{72}[/tex]
Required
Which option is true
Express 32 as 16 * 2 and 72 as 36 * 2
[tex]6\sqrt{32} - 12\sqrt{72} = 6\sqrt{16 * 2} - 12\sqrt{36 * 2}[/tex]
Split
[tex]6\sqrt{32} - 12\sqrt{72} = 6\sqrt{16} * \sqrt{2} - 12\sqrt{36} * \sqrt{2}[/tex]
This gives:
[tex]6\sqrt{32} - 12\sqrt{72} = 6*4 * \sqrt{2} - 12*6 * \sqrt{2}[/tex]
[tex]6\sqrt{32} - 12\sqrt{72} = 24 * \sqrt{2} - 72 * \sqrt{2}[/tex]
[tex]6\sqrt{32} - 12\sqrt{72} = 24 \sqrt{2} - 72 \sqrt{2}[/tex]
Since both term have the same radicand, then:
[tex]6\sqrt{32} - 12\sqrt{72} =( 24 - 72 )\sqrt{2}[/tex]
[tex]6\sqrt{32} - 12\sqrt{72} =-48\sqrt{2}[/tex]
Option (d) is correct

Give the domain and range of the relation then determine if the relation is a function (-3,3), (1, 1), (0, -2), (1, -4), (5, -1)
Domain:_____
Range:_____
Function?_____
PLEASE HURRY
Answers
*domain is the x-value, input, independent
Ranges: {-4, -2, -1, 1, 3}
*range is the y-value, output, dependent
LIST BOTH FROM LEAST TO GREATEST
Functions are when each input(x) has one and only one output(y)
If you were to graph a function, no points would line up vertically with one another.
This question would not be a function because an input (number 1 in this case) has more than one output (1 AND -4)
So function? No.

Find the area of the shaded area using the given dimensions:
The shaded area is divided up into two triangles, each with a base of 2 cm and a height of 2 cm. Use the following equation to solve for area:
A = 1/2(bh)
A = 1/2(2 · 2)
A = 1/2(4) = 2 cm²
There are two triangles, therefore:
2 × 2 = 4 cm²

Answers
Given:
The rate of interest on three accounts are 7%, 8%, 9%.
She has twice as much money invested at 8% as she does in 7%.
She has three times as much at 9% as she has at 7%.
Total interest for the year is $150.
To find:
Amount invested on each rate.
Solution:
Suppose x be the amount invested at 7%. Then,
The amount invested at 8% = 2x
The amount invested at 9% = 3x
Total interest for the year is $150.
[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]
Multiplying both sides by 100, we get
[tex]7x+16x+27x=15000[/tex]
[tex]50x=15000[/tex]
Dividing both sides by 50, we get
[tex]x=\dfrac{15000}{50}[/tex]
[tex]x=300[/tex]
So, the amount invested at 7% is [tex]300[/tex].
The amount invested at 8% is
[tex]2(300)=600[/tex]
The amount invested at 9% is
[tex]3(300)=900[/tex]
Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

You put $500 in a savings account. The account earns $20 simple interest in 6 months. What is the annual interest rate? Write your answer as a percent
Answers
Answer:
8%
Step-by-step explanation:
For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.
For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.
20 = (500)(r)(0.5)
20 = 250r
r = 0.08 = 8%
Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. For the scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.

Solve |x–1| = 6x + 12
Answers
Answer:
[tex]x = - \frac{11}{7} [/tex]
Step-by-step explanation:
1) Break down the problem into these 2 equations.
[tex]x - 1 = 6x + 12[/tex]
[tex] - (x - 1) = 6x + 12[/tex]
2) Solve the first equation. x - 1 = 6x + 12
[tex]x = - \frac{13}{5} [/tex]
3) Solve the second equation: -( x - 1 ) = 6x + 12.
[tex]x = - \frac{11}{7} [/tex]
4) Collect all solution.
[tex]x = - \frac{13}{5}. - \frac{11}{7} [/tex]
5) Check solution.
When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.
When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.We will drop x=-\frac{13}{5}x=−513 from the solution set.
6) Simplify.
[tex]x = - \frac{11}{7} [/tex]
Therefor, the answer is x = - 11/7.
