If q(x)=7x^2-1 find q(-9)
liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:


q(x)=7x^{2} -1


q(-9)=7(-9)^{2} -1


q(-9)=7(81)-1


q(-9)=566


Now we know that q(-9) is equal to 566.

Using the following picture which side is the hypotenuse?
mylen [45]

Hi!

A <u>hypotenuse</u> is the longest leg in a right triangle.

A <u>right triangle</u> is a triangle that has one 90 degree angle.

The hypotenuse is always directly across from the right angle.

In pictures, right angles are represented by a square.

<u><em>Therefore, the side with the hypotenuse is side 3</em></u>, because we can see that the angle between side 1 and side 2 is the right angle, and the hypotenuse would be directly across.

Nutka1998 [239]
Given the frequency table on the relationship between red hair and green eyes.
                       Green Eyes            Eye Color other than Green             Total
Red Hair                18                                       29                                    47

Hair Color
other than             114                                     650                                  764
Red

Total                     132                                     679                                   811

The relative frequency table is obtained from a frequency table by dividing each entry of the requency table by the overall total of the frequency table.

The relative frequency table of the frequency table above is given below.
                       Green Eyes              Other Eye Color                    Total
Red Hair   18/811 = 0.02 = 2%      29/811 = 0.04 = 4%    47/811 = 0.06 = 6%

Other Hair
Color       114/811 = 0.14 = 14%|650/811 = 0.80 = 80%|764/811 = 0.94 = 94%

Total        132/811 = 0.16 = 16%|679/811 = 0.84 = 84%|811/811 = 1.0 = 100%

Given that x is the relative frequency of people that have other hair color and have green eyes, thus, the value of x is 14%.

Therefore, <span>the value of x in the table = 14%.</span>
