You could draw a pie graph, I'm assuming you know how to draw one but I'll tell you anyways. draw a circle with sixty slices, like pizza. shade in 15 percent, or nine sclices. that's my favorite way to model percentages.

an angle measures 24° less than the measure if a supplementary angle . what is the measure of each angle​
vagabundo [1.1K]

Hey there!

If two angles are supplementary, that means that the measures of the two angles have a sum of 180.

If the two angles were of equal measure, they would both be 90 degrees.

The easiest way to get this would be to subtract 12 degrees from one 90 degree angle and add them to the other 90 degree angle so one angle has 24 more degrees then the other.

90 - 12 = 78

90 + 12 = 102

Let's check to make sure this works.

102 + 78 = 180 That checks out.

102 - 24 = 78 That also works.

So, the measures of the angles are 102 and 78.

Hope this helps!

What are the zeros of the polynomial function? f(x)=x^3+x^2−9x−9
ella [17]

Answer:

1: x = -1

2: x = 3

3: x = -3

Step-by-step explanation:

f(x)=<u>x^3+x^2</u>−9x−9

f(x)=x^2<u>(</u>x+1) <u>−9x−9</u>

f(x) = x^2<u>(x+1)</u> - 9<u>(x+1)</u>

f(x)= (x+1)<u>(x^2-9)</u>

f(x) =(x+1)(x-3)(x+3)

The graph below is a portion of a complete graph. Which graph below is the complete graph assuming it is an even function?
Ierofanga [76]

Answer:

Option b

Step-by-step explanation:

A function is even if and only if f(-x) = f(x).

This means that there is the same value of y for x_0 and for -x_0

Where x_0 is any point belonging to the function .

Therefore you must select a graph whose ordered pairs are of the form (x_0, y_0) and (-x_0, y_0)

Therefore the correct answer is option b. Assume that each box in the graph equals 1 unit. Then, for x = 2 y = -3 and for x = -2 y = -3. Then it is shown that the function is even.
