Step-by-step explanation:
a. the zeroes of the function :
x = 2 or x = -2
b. the y-intercept :
g(0) = -3(0-2)(0+2)
= -3(-2)(2) = 12
the coordinates => (0, 12)
c. the g(x) = g(-x) => this is the even function

three different purposes for determining the derivative.
Answer:
A derivative is a slope function. If you want to find the slope anywhere along the function, you can.
Explanation:
Given: What is the purpose of a derivative?
A derivative is a slope function: m=f'(x=value). If you want to find the slope anywhere along the function, you can.
If you want to find a tangent line at a specific point along the function you can, using the slope and the point: y−y1=m(x−x1)
Answer:
See below
Step-by-step explanation:
A derivative is a slope function, so it allows you to find the slope anywhere along a function where it's continuous.
For example, the derivative of velocity is acceleration, which is applicable in real life.
You can also find a tangent line at a specific point by finding the slope of the function at that point and then using point-slope form [tex]y-y_1=m(x-x_1)[/tex] to get your tangent line.
At a high school, the probability that a student is a senior is 0.20. The
probability that a student plays a sport is 0.15. The probability that a student
is a senior and plays a sport is 0.05.
What is the probability that a randomly selected student plays a sport, given
that the student is a senior?
• A. 0.05
• B. 0.25
• C. 0.33

What would be the most logical first step for solving this quadratic equation?
x²+2x-11=4
A. Add 11 to both sides
B. Take the square root of both sides
C. Divide both sides by x
D. Subtract 4 from both sides
Answer:
D. Subtract 4 from both sides
Step-by-step explanation:
When you're solving a quadratic equation you want to use the quadratic formula [tex]\frac{-b+ \sqrt[]{b^{2} -4ac } }{2a}[/tex].
To get the quadratic equation into this form, you first need to convert it into [tex]ax^{2} +bx+c=0[/tex] which means the first step would be to subtract 4 on both sides.

Explain how you know 1 5/8 is little greater than 1 1/2.
Answer:
1 5/8 is 1/8 greater than 1 1/2
Step-by-step explanation:
if we take off the one from both expressions, we're left with
5/8 and 1/2.
To better compare the fractions, we can make them have equal denominators. To do this, multiply both the numerator and denominator of 1/2 by 4: (1*4)/(2*4) = 4/8.
5/8 is larger than 4/8 by 1/8, therefore, 1 5/8 is larger than 1 1/2 by 1/8.
Step-by-step explanation:
1 5/8 is greater than 1 1/2 because if you draw 1 5/8 and on the bottom 1 1/2 you will see that 1 5/8 is greater.

Mega Movers charges $19.50 per day for truck rentals, plus an additional mileage fee of $0.95 per mile. U-Move-It charges $42.00 per day for truck rentals, plus an additional mileage fee of $0.45 per mile for mileage over 20 miles. Which of the following systems of equations could be used to find the total mileage, m, that will make the cost, p, of renting a moving truck for one day equal at each rental company, assuming m≥20, is greater than or equal to, 20?
The equation used to find the total mileage, m, that will make the cost, p, of renting a moving truck for one day equal at each rental company is 45 miles
EquationTotal mileage = mCost = pMega movers:
Fixed cost per day = $19.50
Additional cost per mileage = $0.95
p = 19.50 + 0.95m
U-move:
Fixed cost per day = $42.00
Additional cost per mileage =$0.45
p = 42.00 + 0.45m
Equate the cost of both company19.50 + 0.95m = 42.00 + 0.45m
0.95m - 0.45m = 42.00 - 19.50
0.50m = 22.50
m = 22.50 / 0.50

scale factor = 2
X'' = (8, -4)Y'' = (-6, -10)Z'' = (2, 14)Part (c)
Reflect across the x-axis: (x, y) → (x, -y)

The radius of a cylindrical construction pipe is 2.5 ft. If the pipe is 20 ft. long, what is its volume?
Use the value 3.14 for pi, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
Answer: The volume of the pipe is 412 cubic feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π x radius² x height (Length in this case)
Replacing with the values given:
V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet (rounded)
In conclusion, the volume of the pipe is 412 cubic feet
Feel free to ask for more if needed or if you did not understand something.
Answer:
V = 392.5 cubic feet
Step-by-step explanation:
[tex]v=\pi r^{2} h=\pi (2.5)^{2} (20)=\pi (6.25)(20)=125\pi[/tex]
[tex]\pi =3.14[/tex]

Answer:
[tex] I = \frac{1}{8} e^{4x^2} + C [/tex]
Step-by-step explanation:
This can be solved using substitution method. Let us work it out.
[tex] Let \: I = \int xe^{4x^2} dx[/tex]
[tex] \implies \: I = \int e^{4x^2} xdx[/tex]
[tex] Put \:4x^2 = t [/tex]
[tex] \implies 8x dx = dt [/tex]
[tex] \implies x dx = \frac{1}{8}dt [/tex]
[tex] \implies \: I = \int e^{t} \frac{1}{8}dt [/tex]
[tex] \implies \: I = \frac{1}{8} \int e^{t}dt [/tex]
[tex] \implies \: I = \frac{1}{8} e^{t} + C [/tex]
[tex] \implies \: I = \frac{1}{8} e^{4x^2} + C [/tex]
[tex] \implies \: \int xe^{4x^2} dx = \frac{1}{8} e^{4x^2} + C [/tex]

A box has 14 candies in it: 3 are butterscotch, 7 are peppermint, and 4 are taffy. (Each candy falls into only one of these categories.) Laura wants to select two candies to eat for dessert. The first candy will be selected at random, and then the second candy will be selected at random from the remaining candies. What is the probability that the two candies selected are taffy?
The probability that the two candies selected by Laura from the box are taffy which has 14 candies in it: 3 are butterscotch, 7 are peppermint, and 4 are taffy is 0.230.
What is the conditional probability?The conditional probability is the happening of an event, when the probability of occurring of other event is given.
A box has 14 candies in it: 3 are butterscotch, 7 are peppermint, and 4 are taffy. (Each candy falls into only one of these categories.)
Let A is the event of selecting taffy in first attempt. Thus, the probability of it is,
[tex]P(A)=\dfrac{4}{14}[/tex]
Now 13 candies remain, in which 3 taffy candies are present. Let B is the event of selecting taffy in again. Thus, the probability of it is,
[tex]P(B)=\dfrac{3}{13}[/tex]
The probability of happening both event is,
[tex]P(A\cap B)=\dfrac{4}{14}\times\dfrac{3}{13}\\P(A\cap B)=\dfrac{12}{182}[/tex]
The probability that the two candies selected by Laura from the box are taffy is,
[tex]P(B| A)=\dfrac{\dfrac{12}{182}}{\dfrac{4}{14}}\\P(B| A)=0.230[/tex]
Thus, the probability that the two candies selected by Laura from the box are taffy which has 14 candies in it: 3 are butterscotch, 7 are peppermint, and 4 are taffy is 0.230.

Answer: 3.8 vitamins
Step-by-step explanation:
First, we will find all the data values by looking at the graph.

Next, we will solve for the mean. This is where we add all the data values together, and divide by the number of values.
[tex]\displaystyle \frac{1+1+3+5+9}{5}[/tex]
[tex]\displaystyle \frac{19}{5}[/tex]
3.8
The mean is 3.8.
Answer:
3.8 vitamins
Step-by-step explanation:
Step 1: Determine the mean of the data
The mean of the data is also known as the average of the data. We get this by adding up all of the values and dividing it by the amount of values that we have.
In this example, we have two points on the 1 marker, one point on the 3 marker, one point on the 5 marker, and one point on the 9 marker.
We add up all of the values, 1 + 1 + 3 + 5 + 9 and we get 19. We then divide the number of values that we have which is 5. So we do 19/5 and we get 3.8 vitamins is the mean.
