4. A line with the preimage equation y = 12x is translated 4 units to the right along the x-axis and 25 units up along the y-axis. Which is the equation of the image line?
Answer:
(d) y' = 12x -23
Step-by-step explanation:
The transformation that translates function y = f(x) by h units right and k units up is ...
y' = f(x -h) +k
__
Your function is ...
y = 12x
and you want to translate it by (h, k) = (4, 25). That makes it ...
y' = 12(x -4) +25 = 12x -48 +25
y' = 12x -23

Which equation represents the circle described? the radius is 2 units. the center is the same as the center of a circle whose equation is x2 y2 – 8x – 6y 24 = 0. (x 4)2 (y 3)2 = 2 (x – 4)2 (y – 3)2 = 2 (x – 4)2 (y – 3)2 = 2² (x 4)2 (y 3)2 = 2²
The equation of the circle x² +y² – 8x – 6y + 21 = 0 is equal to the equation (x + 4)² + (y − 3)² = 2². Then the correct option is C.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
x² + y² – 8x – 6y + 21 = 0
The equation can be written as
x² – 8x + 16 + y² – 6y + 9 = 4
(x + 4)² + (y − 3)² = 2²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.

Natasha is a regional manager for a chain of supermarkets. she has been tasked with researching the weekly sales records of two branch locations over the past month, which she must present to her board of directors. she was able to assemble the relevant information in the table below, but it is scrambled and hard to read. sales are listed in thousands of dollars. week 4 1 1 3 4 2 3 2 sales 16.3 17.8 23.1 15.2 20.2 23.4 22.9 17.6 branch north south north south south north north south in order to make the data more readable, natasha has decided to put it into a graph. which of the following graphs accurately matches the information in the table? i.a bar graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, from 15 to 23. week 1 north, 23.1; week 2 north, 23.4; week 3 north, 22.9; week 4 north, 16.3. week 1 south, 17.8; week 2 south, 17.6; week 3 south, 15.2; week 4 south, 20.2. ii. a line graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, going from 15 to 23. iii.a graph has week on the x-axis and sales (dollars times 1,000) on the y-axis, going from 15 to 23. points are plotted all over the graph. iv. a pie chart titled sales (dollars times 1,000). north 1, 16.3; north 2, 17.8; north 3, 23.1; north 4, 15.2; south 1, 20.2; south 2, 23.4; south 3, 22.9; south 4, 17.6. a. i b. ii c. iii d. iv
The graph which accurately matches Natasha's data for the chain of supermarkets is a bar graph.
How to read the data from the table?A table is a way to represent the data of two or more variables.
To read the data from the table look for the value of one variable, and get the resultant value of another variable from the corresponding block.
Natasha was able to assemble the relevant information in the table below,
Sales are listed in thousands of dollars.
Week - 4 1 1 3 4 2 3 2
Sales- 16.3 17.8 23.1 15.2 20.2 23.4 22.9 17.6
Branch- North South North South South North North South
To show the sales with respect to the time period, the best data chart is the bar graph. In a bar graph, the height of the bars is proportional to the data value it possesses.
Here, for the sales by the Natasha the bar graph should be used as, the bar graph has a week on the x-axis and sales (dollars times 1,000) on the y-axis, from 15 to 23.
Week 1 North, 23. 1; week 2 north, 23. 4; week 3 north, 22. 9; week 4 north, 16. 3. Week 1 south, 17. 8; week 2 south, 17. 6; week 3 south, 15. 2; week 4 south, 20. 2.
Hence, the graph which accurately matches Natasha's data for the chain of supermarkets is the bar graph.

Which statement best describes how to determine whether f(x) = x4 – x3 is an even function? determine whether (–x)4 – (–x)3 is equivalent to x4 – x3. determine whether (–x4) – (–x3) is equivalent to x4 x3. determine whether (–x)4 – (–x)3 is equivalent to –(x4 – x3). determine whether (–x4) – (–x3) is equivalent to –(x4 x3).
Since f(x) ≠ f(- x) then f(x) is not an even function. (–x)^4 – (–x)^3 is equivalent to x^4 – x^3.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
We need to find f(x) = x^4 – x^3 is an even function
If 2 functions are even, then
f(x) = f(- x)
f(x) = [tex]- x^3[/tex]
f(- x) = [tex]- (- x)^3 = + x^3[/tex]
Since f(x) ≠ f(- x) then f(x) is not an even function.

The first equation in the system models the height, h, of a falling volleyball as a function of time, t. the second equation models the height, h, of the hands of a player jumping up to spike the ball as a function of time, t. which statement describes the situation modeled by this system?
The volleyball is 14 feet above the ground at the instant the player begins her jump.
What is the equation of motion?It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.
We have two equation for two different situations:
[tex]\rm h(t) = 14 - 16t^2\\[/tex] (falling volleyball as a function of time t)
[tex]\rm h(t) = 7+24t-16t^2[/tex] (the hands of a player jumping up to spike the
ball as a function of time t)
First, we have to find the height of the ball above the ground at the instants the player begins to jump:
At t = 0 when the player begins to jump
Put t = 0 in the second equation, we get:
[tex]\rm h(0) = 7+24\times 0-16\times0^2[/tex]
Height of the hand, h = 7 units
Now put t = 0 in the first equation, we get;
[tex]\rm h(0) = 14 - 16\times0^2[/tex]
h = 14 units.
Thus, the volleyball is 14 feet above the ground at the instant the player begins her jump.

Where,
r refers to the radius of the cone.h refers to the height of the cone.Now, we will substitute the values in the formula :
