Suppose you have 48 feet of fencing to enclose a rectangular dog pen. The function

Rufina [12.5K]

Take first derivative of area function and set it to zero

da/dx=24 - 2x=0

Now it is set to zero add -2x to both side

24 - 2x = 0

24 = 2x

Now divide by 2 in both sides

12 = Width

Your width now is 12

Plug 12 into you equation like this:

24 (12) - 12^2= A

288 - 144 = A

144 = Area

144 feets is the maximum area using the width 24

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.

KengaRu [80]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals $5^{10}$ or not

Take for instance:

$5^5 * 5^5$

Using law of indices:

$5^5 * 5^5 = 5^{5+5$

$5^5 * 5^5 = 5^{10$ ---- equivalent

$\frac{5^5 + 5^5}{2 * 5^{-5}}$

Factorize the numerator

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}$

Cancel out 2

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}$

Apply law of indices

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10$ ---equivalent

$125 * 78125$

Express as exponent

$125 * 78125 = 5^3 * 5^7$

Apply law of indices

$125 * 78125 = 5^{3+7$

$125 * 78125 = 5^{10$ ---- equivalent

$5^3 + 5^7$

Solve exponents

$5^3 + 5^7 = 125 + 78125$

$5^3 + 5^7 = 78250$ ---- not equivalent

Solve for xxx.<br> Your answer must be simplified.<br> x/7≥−6

uysha [10]

Answer:

x ≥ −42

Step-by-step explanation:

Let's solve your inequality step-by-step.

x/7≥−6

Step 1: Simplify both sides of the inequality.

$\frac{1}{7}x\geq -6$

Step 2: Multiply both sides by 7.

$7*(\frac{1}{7}x)\geq (7)*(-6)$

x ≥ −42
