Find the domain of f(x) = 2x for the range {-8, 4, 12, 20).

olga2289 [7]

Step-by-step explanation:

So technically, your replacing the x, with -8, 4, 12, 20. So bassically it would be 2*-8, 2*4, 2*12, 2*20. And those answers you get will get you, your range, so 2*-8 would be -16, 2*4= 8, 2*12=24, 2*20=40

So your ranges would be, -16, 8, 24 and 40.

Find the square root of 3.6 upto 2 decimal places. *With Solution I need*

almond37 [142]

Answer:

The square root is 1.90

Step-by-step explanation:

Given

$x = \sqrt{3.6}$

Required

Find x

Express 3.6 as 36/10

So, we have:

$x = \frac{\sqrt{36}}{\sqrt{10}}$

This gives

$x = \frac{6}{\sqrt{10}}$

Rationalize

$x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}$

$x = \frac{6\sqrt{10}}{10}$

Using a calculator

$\sqrt{10} \approx 3.16$

So, we have:

$x = \frac{6*3.16}{10}$

$x = \frac{18.96}{10}$

$x = 1.896$

Approximate

$x = 1.90$

A fence on a hill uses vertical posts L and M to hold parallel rails N and P. If m∠1 = 115, then what is the measure of ∠16?

kiruha [24]

Step-by-step explanation:

Given information:

A fence on a hill uses vertical posts L and M to hold parallel rails N and P

The diagram is attached below

Here lines N and P are parallel lines

Transversal line for parallel lines N and P is line L

Calculation:

angle 1 and angle 16 are consecutive exterior angles

If parallel lines are cut by a transversal then consecutive exterior angles are supplementary

So measurement of angle 16 = 65 degrees
