F(x) = –x2 – 3
B.
F(x) = x2 – 3
C.
F(x) = –(x + 3)2
D.
F(x) = –(x – 3)2
Answer:
the answer is A
Step-by-step explanation:
The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has been changed somewhat. Which of the following could be the equation of F(x)?
The function that represents the situation is F(x) = -x² - 3.
The correct option is A.
What is transformation on the graphs?Let the functions f(x) and g(x) be two real functions.
And g (x) = f (x) + k, where k is real numbers.
The function can be sketched by shifting f (x), k units vertically.
The value of k can find the direction of shift:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
Given that the parent function is g(x) = x².
To find the transformed function F(x):
The function's diagram is in the opposite direction.
That means the function is -x².
And the function is shifted 3 units down vertically.
From the definition the required function is,
F(x) = -x² - 3.
Therefore, F(x) = -x² - 3.

The coordinates of 4 points are A(0,9), B(k + 1, k + 4), C(2k, k + 3) and
D(2k + 2, k + 6). Find the value(s) of k if
(a) the points A, B and C are collinear,
(b) AB is parallel to CD.
9514 1404 393
Answer:
(a) 2 or 3
(b) -13
Step-by-step explanation:
(a) A, B, and C are collinear if there is some constant 'c' such that ...
B - A = c(C - A)
This will give rise to two equations in 'c' and 'k'.
(k +1, k +4) -(0, 9) = c((2k, k+3) -(0, 9))
(k +1, k -5) = c(2k, k -6)
And the two equations are ...
k +1 = 2ck
k -5 = c(k -6)
From the first, we find ...
c = (k +1)/(2k)
From the second, we find ...
c = (k -5)/(k -6)
Equating these expressions for c gives ...
(k +1)/(2k) = (k -5)/(k -6)
(k +1)(k -6) = 2k(k -5) . . . . . . . multiply by 2k(k-6)
k^2 -5k -6 = 2k^2 -10k
0 = k^2 -5k +6 = (k -3)(k -2)
Solutions that make the factors zero are ...
k = 3 or k = 2
There are two values of k that make the points collinear: 2 and 3.
__
(b) AB is parallel to CD when the slopes of the lines between them are the same
slope of AB = (k+4 -9)/(k+1 -0) = (k -5)/(k +1)
slope of CD = ((k +6 -(k +3))/(2k +2 -2k) = 3/2
Equating these slopes and solving for k, we get ...
(k -5)/(k +1) = 3/2
2(k -5) = 3(k +1)
2k -10 = 3k +3
-13 = k
AB is parallel to CD when k = -13.

A computer cost $800. It loses 1/4 of its value every year after it is purchased. complete the table to show the value of the computer at the listed times. Write an equation representing the values, v, of the computer, years after it is purchased. Used your equation to find v when t is 5. What does this value of v mean?
Answer:
The value after 0 years = $ 800
The value after 1 year = $600
The value after 2 years = $450
The value after 3 years = $337.5
The value after n years = computer cost at (n-1) year -
Step-by-step explanation:
he cost of computer = $ 800It losed 1/4th of value every year.The value of computer after 0 years = cost of computer = $ 800The value after 1 year = 800 - ( ) = $600The value after 2 years = 600 - ( ) = $450The value after 3 years = 450 - ( ) = $337.5The value after n years = computer cost at (n-1) year -We can conclude that -
the equation representing the value {v} of the computer, years after it is purchased as → v{x} = 800(1/4)ˣ.For {x} = 5, the value of {v} would be 0.39.What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that a computer cost $800. It loses 1/4 of its value every year after it is purchased.
We can write the equation representing the value {v} of the computer,
years after it is purchased as -
v{x} = 800(1/4)ˣ
For {x} = 5, we can write -
v{5} = 400(1/4)⁵
v{5} = 400 x 0.0009765625
v{5} = 0.39
Therefore, we can conclude that -
the equation representing the value {v} of the computer, years after it is purchased as → v{x} = 800(1/4)ˣ.For {x} = 5, the value of {v} would be 0.39.To solve more questions on functions, visit the link below-

Abigail is going to cover the label on a Pringle's can and decorate it for
Mother's Day. The can has a diameter of 4.5 inches and a height of 14
inches. What is the minimum amount of paper that she needs for the
project?
Answer:
[tex]Area = 229.6125in^2[/tex]
Step-by-step explanation:
Given
[tex]h = 14in[/tex] --- height
[tex]d =4.5in[/tex] --- diameter
Required
The minimum amount of paper needed
This implies that we calculate the surface area of the can (cylinder)
This is calculated as:
[tex]Area = 2\pi r(r + h)[/tex]
Where
[tex]r = \frac{1}{2}d[/tex]
So, we have:
[tex]r = \frac{1}{2} *4.5[/tex]
[tex]r = 2.25[/tex]
This gives:
[tex]Area = 2 * 3.14 * 2.25(2.25 + 14)[/tex]
[tex]Area = 2 * 3.14 * 2.25*16.25[/tex]
[tex]Area = 229.6125in^2[/tex]

Yes they are equivalent. You get -3 when you try solving the actual equation.
The point-slope form of the equation of the line that passes through (–4, –3) and (12, 1) is y – 1 = y minus 1 equals StartFraction one-fourth EndFraction left-parenthesis x minus 12 right-parenthesis.(x – 12). What is the standard form of the equation for this line?
Given:
The line passes through the two points (–4, –3) and (12, 1).
The point-slope form of the equation of the line is:
[tex]y-1=\dfrac{1}{4}(x-12)[/tex]
To find:
The standard form of the equation for this line.
Solution:
The standard form of a line:
[tex]Ax+By=C[/tex]
The given point-slope form of the equation of the line is:
[tex]y-1=\dfrac{1}{4}(x-12)[/tex]
Multiply both sides by 4.
[tex]4(y-1)=(x-12)[/tex]
[tex]4y-4=x-12[/tex]
[tex]-4+12=x-4y[/tex]
[tex]8=x-4y[/tex]
Interchanging the sides, we get

If you place a 38-foot ladder against the top of a 32-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.
Answer: 20.5
Step-by-step explanation:
The distance between the bottom of the ladder from the bottom of the building will be 20.5 feet.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
In the event that you place a 38-foot stepping stool against the highest point of a 32-foot building.
Let 'x' be the horizontal distance on the ground. Then the equation is given as,
38² = 32² + x²
Simplify the equation, then we have
1444 = 1024 + x²
x² = 420
x = 20.5 feet
The distance between the bottom of the ladder from the bottom of the building will be 20.5 feet.

What is the combined area of the four blades, in square inches?
Answer:
[tex]Area = 24\ in^2[/tex]
Step-by-step explanation:
Given
Let
[tex]a, b \to[/tex] opposite sides of each trapezoid
[tex]h \to[/tex] height
[tex]a = 2; \ \ \ b = 4 \ \ \ \ h = 2[/tex]
See attachment for trapezoids
Required
The combined area of the 4
First, we calculate the area of 1
[tex]Area = \frac{1}{2}(a + b) * h[/tex]
So:
[tex]A_1 = \frac{1}{2}(2 + 4) * 2[/tex]
[tex]A_1 = \frac{1}{2}*6 * 2[/tex]
Using a calculator
[tex]A_1 = 6[/tex]
The combined area is:
[tex]Area =n * A_1[/tex]
Where
[tex]n = 4[/tex] --- 4 blades
So:
[tex]Area = 4 * 6[/tex]
[tex]Area = 24\ in^2[/tex]
A line for tickets to a Broadway show had a mean waiting time of 20 minutes with a standard deviation of 5 minutes.
What percentage of the people in line waited for more than 28 minutes?
Answer:
5.48% of the people in line waited for more than 28 minutes
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean waiting time of 20 minutes with a standard deviation of 5 minutes.
This means that [tex]\mu = 20, \sigma = 5[/tex]
What percentage of the people in line waited for more than 28 minutes?
The proportion is 1 subtracted by the p-value of Z when X = 28. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{28 - 20}{5}[/tex]
[tex]Z = 1.6[/tex]
[tex]Z = 1.6[/tex] has a p-value of 0.9452.
1 - 0.9452 = 0.0548.
As a percentage:
0.0548*100% = 5.48%
5.48% of the people in line waited for more than 28 minutes
