Answer:

D. 54/n¹¹

Step-by-step explanation:

(6n⁻⁵)(3n⁻³)²

<em>Note that (ax)ᵇ=aᵇxᵇ</em>

(6n⁻⁵)(3²)(n⁻³)²

(6)(n⁻⁵)(9)(n⁻³)²

54(n⁻⁵)(n⁻³)²

<em>Note that (xᵃ)ᵇ=xᵃᵇ</em>

54(n⁻⁵)(n⁻³⁽²⁾)

54(n⁻⁵)(n⁻⁶)

54(n⁻⁵)(n⁻⁶)

54(n⁻⁵)(n⁻⁶)

<em>Note that (xᵃ)(xᵇ)=xᵃ⁺ᵇ</em>

54(n⁻⁵⁻⁶)

54n⁻¹¹

<em>Note that x⁻ᵃ=1/xᵃ</em>

54/n¹¹

What is the measure of angle x?
Kitty [74]

The two horizontal lines are parallel.

This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.

This means x + 20 needs to equal 80.

X = 80-20 = 60 degrees.

Paki answeran naman po​
Bogdan [553]

Answer:

For the 1st one the answer is 2/3 x 1/2 = 0.333 repeating and the 2nd one is 3/5 x 1/3 = 0.2

Step-by-step explanation:

The amount of boxes in total is the denominator and the amount of boxes shaded is the numerator, so if you put those to together it creates a fraction. So multiply the first fraction and the second fraction and you get your answer.

Identify the domain and range of each graph
vova2212 [387]

Answer:

Step-by-step explanation:

You didn't mark your graph but I'm assuming the point is (1,2)

You notice how the function stops at the point? x and y can not be above that point because there is no line above it.

The domain of the function means what can x possibly be.

The maximum value of x in this function is 1 because that's the x value of the point where the function ended. This means x can at most be one or x≤1. So the domain is x≤1.

The range of the function means what can y possibly be.

The maximum value of y in this function is 2 because that's the y value of the point where the function ended. This means y can at most be two or y≤2. So the range is y≤2.
