Answer:
g(x) = | x + 7 |
Step-by-step explanation:
The absolute value graph f(x)=|x| is a V-shaped graph with the vertex (tip, point) at (0,0). The graph shown has been translated (slid, shifted) 7 units to the left. Left or right shifts, horizontal shifts, are caused by an adjustment to the x. Horizontal shifts are also maybe the opposite of your intuition. Left shifts, you ADD to x. Right shifts, you subtract from x.
This is a left shift, so adjust the x by inserting a +7
f(x) = |x|
g(x) = | x + 7 |

point a: (-7, 8) what is the equation of the circle with a center at the point and a radius of 4 units?
The equation of the circle with a center at the point (-7,8) and a radius of 4 units is (x + 7)² + (x - 8)² = 16.
The standard form of a circle with a center at (h,k) and a radius r is
(x - h)² + (x - k)² = r².
Since we have center as a point A which is (-7,8) and radius of circle as 4 units ,
h = -7
k = 8
r = 4
Thus the equation of circle is,
(x -(-7))² + (x - 8)² = 4²
This equation simplifies to be ,
(x + 7)² + (x - 8)² = 16
A circle is a two-dimensional object made up of points that are spaced out from a given point (centre) on the plane by a fixed or constant distance (radius). The fixed point is referred to as the circle's origin or center, and the fixed distance between each point and the origin is referred to as the radius.

The mean decreases from the original value. The median stays the same.
how to determine what happens to the mean and median(a) To find the new mean, we need to add up all the numbers in the list (except for the 523 that changed to 424) and divide by the number of schools (which is still 9). So the new mean is:
(164 + 225 + 227 + 250 + 261 + 268 + 277 + 379 + 424) / 9 = 272.89
The mean decreases from the original value.
(b) To find the new median, we need to arrange the numbers in order again:
164, 225, 227, 250, 261, 268, 277, 379, 424
The median is the middle value, which is still 261. So the median stays the same.

Where:
x and y represent the data points.m represent the slope.First, we would find the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (6 - 3)/(2 + 1)
Slope (m) = 3/3
Slope (m) = 1.
At data point (-1, 3) and a slope of 1, an equation for this line can be calculated by using the point-slope form as follows:

At your school, 74% of students bought their lunch at the cafeteria. There are
1250 students in the school. How many students bought their lunch?
925
students who brought their lunch. YUM!!
Answer
925 students brought their lunch.
Explanation
First let's rewrite the equation.
You know that "of" means multiply and "is" means equal.
Okay, so let's break it down.
The question says, "At your school, 74% of students brought their lunch at the cafeteria. There are 1250 students in the school."
This means that 74% of 1250 students brought their lunch at the cafeteria.
You are trying to find how many students brought their lunch. This will be x.
So the equation would be this.
74% × 1250 = x
74% is 0.74.
0.74 × 1250 = x
0.74 × 1250 = 925
So 925 students brought their lunch.

The x-intercepts and the y-intercept of the cubic function f(x) = x³ - 9·x² + 20·x - 12 for which (x - 6) is a factor are;
The x-intercepts are; (6, 0), (2, 0), and (1, 0)The y-intercepts of the function is the point (0, -12)What is a function?A function is a rule that uniquely maps each value from the set of input variables to exactly one value in the set of the output variables.
The specified cubic function is; f(x) = x³ - 9·x² + 20·x - 12
A factor of f(x) = x - 6
The x-intercepts are the points on the graph of the function, where the value of the function, f(x) = 0, which are found as follows;
At the x-intercept, f(x) = x³ - 9·x² + 20·x - 12 = 0
x³ - 9·x² + 20·x - 12
Dividing the cubic function by the factor (x - 6), we get;
x² - 3·x + 2
(x - 6) | x³ - 9·x² + 20·x - 12
\({}\) x³ - 6·x²
\({}\) -3·x²
\({}\) -3·x² + 18·x
\({}\) 2·x
\({}\) 2·x - 12
\({}\) 0
The other factor of the cubic function is; x² - 3·x + 2
x² - 3·x + 2 = (x -2)·(x - 1)
Therefore;
f(x) = x³ - 9·x² + 20·x - 12 = (x - 6)·(x - 2)·(x - 1)
From which at the x-intercepts, we get;
f(x) = (x - 6)·(x - 2)·(x - 1) = 0
x = 6, x = 2, and x = 1
The x-intercepts are the points (6, 0), (2, 0), and (1, 0)The y-intercept are the points the x-values is zero, therefore, at the y-intercepts, we get;
f(0) = 0³ - 9·0² + 20·0 - 12 = -12

The equivalent inequality is 15x<1. Therefore, option D is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is 7x+5<-2(4x-3).

find the volume of the cylinder

Step-by-step explanation:
Answer:
Where is the cylinder?
Step-by-step explanation:
An arrow is shot from 3 ft above the top of a hill with a vertical upward velocity of 108 ft/s. If it strikes the plain below after 9.5 s, how high is the hill?
If the arrow is launched at t0, then write an equation describing velocity as a function of time?
The height of the hill is approximately 25.73 ft. Where v0 is the initial velocity (108 ft/s), g is the acceleration due to gravity \((-32.2 ft/s^2)\),
To find the height of the hill, we can use the formula for the vertical position of an object under constant acceleration:
h = h0 + v0t + 1/2at^2
where h is the final height, h0 is the initial height, v0 is the initial velocity, t is the time, and a is the acceleration due to gravity (-32.2 ft/s^2).
In this case, we are given that the initial height h0 is 3 ft, the initial velocity v0 is 108 ft/s, and the time t is 9.5 s. We want to find the height of the hill, which we can denote as h_hill. The final height is the height of the plain, which we can denote as h_plain and assume is zero.
At the highest point of its trajectory, the arrow will have zero vertical velocity, since it will have stopped rising and just started to fall. So we can set the velocity to zero and solve for the time it takes for that to occur. Using the formula for velocity under constant acceleration:
v = v0 + at
we can solve for t when v = 0, h0 = 3 ft, v0 = 108 ft/s, and a = -32.2 ft/s^2:
0 = 108 - 32.2t
t = 108/32.2 ≈ 3.35 s
Thus, it takes the arrow approximately 3.35 s to reach the top of its trajectory.
Using the formula for the height of an object at a given time, we can find the height of the hill by subtracting the height of the arrow at the top of its trajectory from the initial height:
h_hill = h0 + v0t + 1/2at^2 - h_top
where h_top is the height of the arrow at the top of its trajectory. We can find h_top using the formula for the height of an object at the maximum height of its trajectory:
h_top = h0 + v0^2/2a
Plugging in the given values, we get:
h_top = 3 + (108^2)/(2*(-32.2)) ≈ 196.78 ft
Plugging this into the first equation, we get:
h_hill = 3 + 108(3.35) + 1/2(-32.2)(3.35)^2 - 196.78
h_hill ≈ 25.73 ft
If the arrow is launched at t0, the equation describing velocity as a function of time would be:
v(t) = v0 - gt

The value of 4 Superscript negative 4 is negative StartFraction 1 Over 4 Superscript negative 4 EndFraction.
In the given table, Tasha observed a pattern in the powers of 4. When the exponent decreases by 1, the previous value is divided by 4. Using this pattern, she determined the values for 4 squared, 4 Superscript 1, 4 Superscript 0, 4 Superscript negative 1, and 4 Superscript negative 2.
To find the value of 4 Superscript negative 3, she divided the previous value (StartFraction 1 Over 16 EndFraction) by 4, resulting in StartFraction 1 Over 64 EndFraction.
Similarly, for 4 Superscript negative 4, she divided the previous value (StartFraction 1 Over 64 EndFraction) by 4, yielding StartFraction 1 Over 256 EndFraction.
Finally, to rewrite the value for 4 Superscript negative 4, she expressed it as negative StartFraction 1 Over 4 Superscript negative 4 EndFraction.
