Well let's check

√32 = √8*4 = 4√2

Yes it can

Hey!

First, we have to break 32 into its primes.
32=2^5
=\sqrt{2^5}
Since we don't want an odd number, we can split it into two.
=\sqrt{2^4\cdot \:2}
=\sqrt{2}\sqrt{2^4}
Since we want to remove one of the square roots, we have to do something like this: \sqrt{2^4}=2^{\frac{4}{2}}=2^2
We would be left with,
=2^2\sqrt{2}
Simplify the exponent.
=4\sqrt{2}
This tells us that the square root of 32 can be simplified.

Thanks!

How to solve the equation 8b - 12 = 5b
Virty [35]

Answer:

b = 4

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

8b - 12 = 5b

<u>Step 2: Solve for </u><em><u>b</u></em>

  1. Subtract 5b on both sides:                    3b - 12 = 0
  2. Add 12 on both sides:                            3b = 12
  3. Divide 3 on both sides:                          b = 4

<u>Step 3: Check</u>

<em>Plug in b to verify it's a solution.</em>

  1. Substitute:                  8(4) - 12 = 5(4)
  2. Multiply:                      32 - 12 = 20
  3. Subtract:                     20 = 20

And we have our final answer!

Anybody know how to work on decay rate? I'll give brainliest. THIS IS DUE SOON SO PLEASE HELP
artcher [175]

Answer:

28%

Step-by-step explanation:

In the function the .72 means that each unit of time 72% of the value is retained. This means that 28% percent of the value is lost or decays because 1-0.72=0.28 or 28 percent.

The test statistic of z= -2.39 is obtained when testing the claim that p&lt;0.52.
krek1111 [17]

Considering the situation described, we have that:

a) The critical value is of z = -1.645.

b) Since the test statistic is less than the critical value, we should reject the null hypothesis H0.

<h3>What is the critical value?</h3>

We have a left-tailed test, as we are testing if the proportion is less than a value. Hence the critical value is z with a p-value equals to the significance level, hence z with a p-value of 0.05, hence z = -1.645.

<h3>What is the decision?</h3>

Considering the test statistic, for a left-tailed test, we have that:

  • Less than the critical value: Reject H0.
  • Equal or greater: Do not reject.

In this problem, z = -2.39 is less than -1.645, hence we should reject the null hypothesis H0.
