The answer is 50 feet. If 1in = 2.5 ft, then 20in is 50 ft.

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-4, -6)

Point (8, -10)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

Substitute [DF]: $d = \sqrt{(8+4)^2+(-10+6)^2}$
Add: $d = \sqrt{(12)^2+(-4)^2}$
Exponents: $d = \sqrt{144+16}$
Add: $d = \sqrt{160}$
Simplify: $d = 4\sqrt{10}$
Evaluate: $d = 12.6491$
Round: $d \approx 12.6$

Vertex = -b/2a = -(44)/2(-1) = -44/-2 = 22
To find the x-intercepts, set the function equal to 0 and solve for x

a students work to simplify is shown below select the statemt which best applies to the sample.mathematical work

Molodets [167]

Answer:

D. The work shown above is correct and $x\times \sqrt[6]{x^{7}}$ may not be simplified further.

Step-by-step explanation:

The expression is given as,

$\sqrt[6]{x^{13}}=\sqrt[6]{x^{6}\times x^{7}}$

i.e. $\sqrt[6]{x^{13}}=x\times \sqrt[6]{x^{7}}$

Then, $\sqrt[6]{x^{13}}=x\times \sqrt[6]{x^{7}}$

Thus, we can see that above calculation is correct.

The right side of step 2 gives, $\sqrt[6]{x^{6}\times x^{7}}=(x^{6})^\frac{1}{6}\times (x^{7})^\frac{1}{6}=x\times \sqrt[6]{x^{7}}$

So, the work shown is correct and $x\times \sqrt[6]{x^{7}}$ may not be further simplified.

Hence, option D is correct.
