if f(x) = -x^3 + x^2 + x, find f(-2)​

Answer:

x = 2.55 miles per day

Step-by-step explanation:

In English:     5 days * 'x' miles per day = 12 & 3/4 miles total

In algebra:    5x = 12.75

                       x = 12.75 ÷ 5

                      x = 2.55 miles per day

Answer:

{9} Slope: -1

Y-intercept = 0

Step-by-step explanation:

Slope-----

Recall slope-intercept form

y=mx+b, with slope m and a y-intercept of b. With this in mind, we can rewrite our equation as y=−x+0

We see that our slope, or coefficient on x, is −1.

Y-intercept-----

We can rewrite this equation as:y=1x+0

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

For this equation:y=1x+0

Therefore:

The slope is m=1

The y-intercept is b=0 or (0,0)

The 1st option

Step-by-step explanation:

Because x can be anything that's not imaginary and y has to be below 2 always because of the negative value added before the 3. Also it's impossible to reverse the sign of the negative because negative x would only result in 3 becoming a fraction.

Answer: correct answer is C

Step-by-step explanation:

The value of m in the figure is √126.

Option C is the correct answer.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

ΔABD is similar to ΔBCD.

This means,

The corresponding sides ratio is equal.

AB/BC = BD/CD = AD/BD

AB/m = BD/7 = 11/BD

Now,

BD/7 = 11/BD

BD² = 77

BD = √77

Now,

ΔBDC

BC² = CD² + BD²

m² = 7² + 77

m² = 49 + 77

m² = 126

m = √126

Thus,

The value of m in the figure is √126.

Answer:

The average rate of change is two feet per second.

Step-by-step explanation:

The height of an arrow shot up into the air from a height of three feet is given by the function:

[tex]h(t)=-2t^2+12t+3[/tex]

And we want to find its average rate of change from one second the four seconds.

The average rate of change is synonymous with the slope. Therefore, we can evaluate the height of the arrow after the first and fourth seconds, and find the slope between them.

After the first second, the height of the arrow is:

[tex]h(1)=-2(1)^2+12(1)+3=13[/tex]

And after the fourth second, the height of the arrow is:

[tex]h(4)=-2(4)^2+12(4)+3=19[/tex]

This yields two points: (1, 13) and (4, 19).

The slope between them is:

[tex]\displaystyle m=\frac{19-13}{4-1}=\frac{6}{3}=2[/tex]

Therefore, the average rate of change from one second to four seconds is two feet per second.

Answer:

Step-by-step explanation:

Given system:

Substitute z in the first two equations with z = 3 - kx:

In order the two equations above not to have a solution, the lines should be parallel. Parallel lines have equal slopes.

Solve the following equation for k:

Hi there!

[tex]\large\boxed{\text{ L = 6 ft, w = 5.5 ft}}[/tex]

Use the following equation for the area of a rectangle:

A = l × w

Since the length is 5 ft less than twice the width, we can write an expression for the length in terms of the width:

l = 2w - 5

Plug the given area and expression into the equation:

33 = (2w - 5) × w

Distribute:

33 = 2w² - 5w

Move everything over to one side:

0 = 2w² - 5w - 33

Factor the equation:

0 = (2w - 11)(w + 3)

Find each w value by setting each expression equal to 0:

0 = 2w - 11

11 = 2w

w = 5.5

0 = w + 3

-3 = w

Since dimensions must be positive, the width is 5.5 ft.

Plug this value into the initial equation to solve for length:

33 = 5.5l

33/5.5 = l

l = 6 ft.

The dimensions are length = 6ft, and width = 5.5ft.

Answer:

B. Same-side interior angles

Step-by-step explanation:

Angle w and angle x lie on the same side of the transversal that cut across the two parallel lines, and are also within the two parallel lines. They are therefore regarded as same-side interior angles. Same-side interior angles are supplementary.

Step-by-step explanation:

The green gems are red gems divided by three. The red gems are gold gems divided by six. Make the number of gold gems, g. The red gems would be g/6, and the green gems (g/6)/2=g/18. So, the total marbles would be g+g/6+g/18=18g/18+3g/18+g/18=22g/18=11g/9. Now you have to find what percent of 11g/9 is g. (11g/9)(percent)=g. The percent as a fraction is 9/11.

Step-by-step explanation:

The women who see the commercials without celebrities is in the controler group. Correct option is A.

In an experiment, the control group is a group of individuals who do not receive the specific treatment or intervention being studied. The purpose of the control group is to serve as a baseline for comparison, allowing researchers to evaluate the impact of the treatment by comparing it to the group that did not receive the treatment.

In this scenario, the clothing manufacturer is trying to determine whether celebrity endorsements influence a customer's decision to buy its products. To evaluate this influence, they are conducting an experiment with two separate groups of potential buyers:

Group A: Potential buyers (women) who will see a series of commercials without celebrities.

Group B: Potential buyers (men and women) who will view a series of commercials with celebrities.

The control group, in this case, is Group A - the women who see the commercials without celebrities. They do not receive the treatment (celebrity endorsements) being studied. Their responses and behavior will serve as a baseline against which the effects of celebrity endorsements on the buying decision can be compared in Group B.

By comparing the responses and behavior of the two groups, the clothing manufacturer can determine whether celebrity endorsements have a significant influence on the customers' decision to buy their products. The control group is essential for ensuring that any observed effects in Group B are not due to other factors but rather can be attributed to the presence of celebrity endorsements.

Step-by-step explanation:

Chance is also referred to as probability

probability = Number of event/Total samples space

If there are 6 black socks,8 white socks,2 red socks, and 4 blue socks in a drawer, the total number of socks will be the sample space

Sample space = 6 + 8 + 2 + 4

Sample space = 20socks

Total number of blue socks is the event

Number of event = 4 blue socks

Chance that the socks is blue = n(E)/n(S)

Chance that the socks is blue = 4/20

Chance that the socks is blue = 1/5
