Answer:

11sqrt(33)

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

9

Step-by-step explanation:

(11/3)^(3/2)

Apply the cube to inside:

(11^3/3^3)^(1/2)

Recall (x^3)^(1/2)=sqrt(x^3)=sqrt(x^2)×sqrt(x)=x×sqrt(x)

So we have:

11sqrt(11)

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

3sqrt(3)

Rationalize denominator by multiplying top and bottom by sqrt(3):

11sqrt(11)sqrt(3)

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

3sqrt(3)sqrt(3)

=

11sqrt(33)

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

3(3)

=

11sqrt(33)

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

Write an exponential function for the value, y, after x years
Anon25 [30]

Step-by-step explanation:

<u>Step 1:  Set x equal to 0 to find the y-int</u>

y = 10000(1 - 0.40) → Not an exponential equation

y=10000(1-0.40)^0 → 10,000 → Works for first test

y = 10000(1-0.60)^0 → 10,000 → Works for first test

y = 10000(1+0.40)^0 → 10,000 → Works for first test

<u>Step 2:  Set x equal to 1</u>

y=10000(1-0.40)^1 → 6,000 → Works for second test

y = 10000(1-0.60)^1 → 4,000 → Does not work for the second test

y = 10000(1+0.40)^1 → 14,000 → Does not work for the second test

Answer:  The answer is Option B

step 2: 8 m + 2 = 3 12 - 4m move the terms

step 3: 8m+ 12m= 36 - 16 collect like terms and calulate

step 4: 20m=20 divide both sides
