3. Use the given information about the polynomial graph to write out the equation.
Degree 5, Roots of multiplicity 2 at x = 3 and x = -2 and a root of multiplicity 1 at x = 4,
y-intercept at (0,12).

Answers

Answer:

[tex]f(x)=-\frac{1}{12}(x-3)^2(x+2)^2(x-4)[/tex]

Step-by-step explanation:

The standard form for a polynomial equation in its factored form is:

[tex]f(x)=a(x-p)(x-q)...[/tex]

Where p and q are the zeros and a is the leading coefficient.

We know that the degree of the polynomial is 5.

We are also given roots at x=3 and x=-2. Hence, our factors are (x-3) and (x+2).

These have a multiplicity of two, so we will square them.

We also know that there is a root at x=4. Hence, the factor is (x-4). This has a multiplicity of 1.

Therefore, our polynomial is now:

[tex]f(x)=a(x-3)^2(x+2)^2(x-4)[/tex]

We know that the y-intercept is 12. Therefore, if we substitute in 0 for x, we should get 12 for y. Here, we are solving for our a. Therefore:

[tex]12=a(0-3)^2(0+2)^2(0-4)[/tex]

Evaluate:

[tex]12=a(9)(4)(-4)[/tex]

Evaluate:

[tex]-144a=12[/tex]

Divide both sides by -144:

[tex]a=-1/12[/tex]

Hence, our entire polynomial is:

[tex]f(x)=-\frac{1}{12}(x-3)^2(x+2)^2(x-4)[/tex]

If angle M is represented by x + 16 and angle G is represented by
X – 40, and angles M and G are complementary, what is the
measure of angle M?

Answers

Answer:

the measure of angle M is 73 degrees

Step-by-step explanation:

the sum of complementary angles is 90 degrees. so set up the equation as:

x+16+x-40=90

combine like terms and you get:

2x-24=90

add 24 on both sides and you get:

2x=114

divide by 2 on both sides to isolate x and you get:

x=57

since the equation for angle M is x+16, you substitute 57 for x and you get:

M=57+16

M=73

The quadrilateral shown is rotated 90° clockwise about the origin. In which quadrant is the image of the quadrilateral located?

Answers

Answer:

Option (2). 1

Step-by-step explanation:

Coordinates of point A, B, C and D are,

A(-4, 4), B(-2, 4), C(-2, 1) and D(-4, 3).

Quadrilateral ABCD when rotated 90° clockwise about the origin,

Rule for the rotation of the vertices,

(x, y) → (y, -x)

Following the rule of rotation coordinates of the image points,

A(-4, 4) → A'(4, 4)

B(-2, 4) → B'(4, 2)

C(-2, 1) → C'(1, 2)

D(-4, 3) → D'(3, 4)

Since all image points have the positive coordinates (x and y coordinates), image quadrilateral A'B'C'D' will be located in 1st quadrant.

Option (2) is the correct option.

A coffee distributor plans to mix some Rift Valley coffee that normally sells for $12.10 per pound with some Mexican Shade Grown coffee that normally sells for $13.10 per pound to create 50 pounds of a new coffee blend that can sell for $12.62 per pound. How many pounds of each kind of coffee should they mix? Answer: pounds of Rift Valley coffee? pounds of Mexican Shade Grown coffee? Round your answers to the nearest whole number of pounds.​

Answers

Answer:

24 pounds of Rift Valley coffee

26 pounds of Mexican Shade Grown coffee

Step-by-step explanation:

If R is pounds of Rift Valley coffee, and M is pounds of Mexican Shade Grown coffee, then:

R + M = 50

12.10 R + 13.10 M = 12.62 (50)

Substitute:

12.10 R + 13.10 (50 − R) = 12.62 (50)

12.10 R + 655 − 13.10 R = 631

R = 24

M = 26

A teacher estimates there are about 600 students at their school. If there are actually 625 students, then what is the percent error of this estimate?

Answers

Answer:

4%

Step-by-step explanation:

(|600-625|)/625 x 100

=4%

Answer:

The percent error for this estimate was 4%.

Step-by-step explanation:

Teacher's estimated students = 600

Actual students = 625

625-600 = 25 students are more than the teacher's estimate.

In other words, the measurement error = 25 students

Now the percent error can be calculated by dividing 25 (measuring error) by the actual students.

Percent error = 25/625 = 0.04 which is 4%

Therefore, the percent error for this estimate was 4%.

Which of the following pairs of functions are inverses of each other?

The answer is (B).

Step-by-step explanation:

A). y = f(x) = 6(x - 2) + 3 ⇔ y = 6x - 12 + 3 ⇔ 6x = y + 9 ⇔ x = [tex]\frac{y+9}{6}[/tex]

g(x) = [tex]\frac{x+9}{6}[/tex] is inverse function of f(x) and ≠ [tex]\frac{x+2}{6}[/tex] - 3

B). y = f(x) = [tex]\frac{5x}{4}[/tex] - 3 ⇔ 4y = 5x - 12 ⇔ x = [tex]\frac{4y+12}{5}[/tex]  

g(x) = [tex]\frac{4(x + 3)}{5}[/tex] is inverse of f(x)

Karl is making a pot of chili. The recipe calls for 3/8 cup of chili powder, but Karl only wants to use half as much so it won’t be so spicy. How much chili powder should Karl use?

Answers

Answer:

KArl should use 3/16 cups of chili powder

Step-by-step explanation:

Given that:

Recipe's requirement : 3/8 cups

Karl wants to use half : 1/2

The given question involves fractions. When the number of cups has to be divided into half, it will be multiplied with 1/2.

So,

Multiplying the chili powder requirement of the recipe to 1/2

[tex]=\frac{3}{8} * \frac{1}{2}\\= \frac{3}{16}[/tex]

Hence,

KArl should use 3/16 cups of chili powder

You've developed a protein drink that you think cures arthritis. to test it, you find 200 volunteers (100 men and 100 women) and test them to measure the amount of discomfort they feel from their arthritis. then you give the treatment to half the subjects and a placebo to the others. you then test them all at regular intervals and measure their improvement. you find that the subjects who received the treatment show marked improvement. the people performing the tests are not told that they're studying an arthritis medication. you excitedly report your findings in an infomercial that is seen by millions of people, and sales skyrocket. but were the test results truly useful for determining the effectiveness of the treatment? why or why not? a. no, there was no control. b. yes, it's a blind-study. c. yes, it's a valid before-and-after design. d. can't be determined without knowing how much improvement was measured. e. no, there was no replication.

Answers

Answer:

I would say C

Step-by-step explanation:

In this experiment the subjects do not know whether they are being given the real treatment or a placebo. Also the testers do not know that treatment for arthritis has been given. The subjects being given the treatment "show marked improvement" according to the tests. Therefore this is a valid double blind experiment, making C the correct choice.

0.3 is greater because it is a positive number. The other one is a negative.

Answer:

0.3 is greater than -0.7

Step-by-step explanation:

If you look at the number line, -0.7 is on the left side of 0, which means is less than 0.
