What is a reflection?In Geometry, a reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.
What is a reflection across the x-axis?In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection across the x-axis is given by this transformation rule: (x, y) → (x, -y).
By applying a reflection across the x-axis to the function, we have;
f(x) = 2|x|
g(x) = -f(x)
g(x) = -(2|x|)
g(x) = -2|x|

diego brought a box of 120 colored pencils to school. he gave 14 pencils to marcus and 32 pencils to anna. how many pencils did diego have left
Answers
Diego will have 74 pencils remaining after giving 14 pencils to Marcus and 32 pencils to Anna.
The question is about simple Subtraction. First, we know that the total number of colored pencils in the box is 120. Following is the step-by-step explanation for this question.
Let suppose,
Total Colored pencils = x = 120
Pencils given to Marcus = y = 14
Pencils are given to Anna = z = 34.
And, Total Pencil Remaining = R =?
We can show the given information in the equation as given below:
R = x - y - z
By putting the value in the above equation:
R = 120 - 14 -34
R = 74.
So, after giving the 14 and 32 pencils to Marcus and Anna, respectively. Marcus would remain with 74 Pencils.

BD is perpendicular to AC, forming two right triangles. The hypotenuses are congruent, as is our leg that we will call b. If we use Law of Sines to find our angles a and c (no matter the values), we would find that because b is the same leg in both triangles and the hypotenuses are congruent, angles a and c are congruent, so therefore your missing angle in both triangles is congruent, and using a trig function will find that AD and CD are congruent, making all of both triangles congruent.
consider the process of throwing $m$ balls into $n$ bins, where each ball is thrown into a uniformly random bin, independent of other balls. what is the expected number of balls in a particular bin $b$?
Answers
The predicted quantity of balls in the first bin is (1/n)n.
Considering that,
There are the same number of balls and containers.
If so, then each container must always contain one ball. The probability of each ball landing in the first bin is (1/n)n.
For instance -
Three balls and three bins should be present. Next to each ball, place an A, B, and C. There are numbers 1, 2, and 3 on the containers. Ball A has a 1/3 chance of landing in bin 1. Although there is a 1/3 probability that ball B will drop in bin 1 and a 1/3 chance that ball C will do the same, both outcomes are possible. Therefore, bin 1 should be equal to 1/3 + 1/3 + 1/3. The rationale behind the projected values of bins 2 and 3 is identical.
According to the same logic, bins 2 and 3 should also have expected values of 1.
How probable is it that the first bin will receive all three balls?
In general, (1/n)n, which equals (1/3)3, or 1/3 x 1/3 x 1/3, equals 1/27.
Therefore, (1/n)n would be the expected number of balls in the first bin.

What is the average rate of change of the functionf(x)=20(14)x from x = 1 to x = 2? enter your answer, as a decimal, in the box. do not round your answer.
Answers
The average rate of change of the function f(x) is found as -3.75.
Explain the term average rate of change?The rate about which one value in a function evolves in proportion to another is known as the average rate of change. The slope of a graphical representation function is typically calculated using the average rate of change.The formula for the average rate of change (A(x)) of f(x) over the interval [a,b] is:
A(x) = f(b) - f(a) / b - a
The function being:
f(x) = 20.(1/4)ˣ
Its average rate of change between x = 1 to x = 2 must be determined.
At x = 1
Then;
f(x) = 20.(1/4)¹
f(1) = 5
At x = 2
Then;
f(x) = 20.(1/4)²
f(2) = 1.25
Add these to the formula above to get;
A(x) = f(2) - f(1) / 2 - 1
A(x) = - 3.75
Consequently, the average rate of change of a function f(x) between x = 1 and x = 2 is -3.75.

What is the short definition of cosine law?
According to a trigonometrical rule, the square of a side in a plane triangle is equal to the sum of the squares of the other sides minus twice that amount plus the cosine of the angle between the other two sides.
Given:
Angle AB = 370 miles 24 degrees is A.
Angle BC = 240 miles 37 degrees is B.
Since we have two angles and two sides of a regular triangle, we can apply the cosine law to calculate the distance between points A and C.
Angle B, which is 37 degrees, is the angle opposite side AC.
(AC)^2 =(AB)^2 + (BC)^2 - 2(AB)(BC)cos(B)
solve for AC:
(AC)^2 =(370)^2 + (240)^2 - 2(370)(240)cos(37)
229,48 miles equal AC.

Answers
The 95% confidence interval for the mean gas mileage for this car model is (26.26, 28.74) mi/gallon.
The confidence interval for a statistical data is written as-
(x+ zr/√n, x- zr/√n)
Here, we are given that-
Mean ⇒ x = 27.5 mi/gallon.
Standard deviation ⇒ r = 4 mi/gallon
Number of samples ⇒ n = 49
and Confidence interval = 95%
z-score at 95% confidence level = 2.17
Substituting the values we have;
= [27.5 - 2.17(4.0) /(√49), 27.5 + 2.17(4.0) /(√49)]
= (27.5 - 8.68 / 7, 27.5 + 8.68 / 7)

Answers
Answer:
y = 1/5x -11
Step-by-step explanation:
You want the slope-intercept equation of the line perpendicular to y=-5x+9 that goes through the point (20, -7).
Slope-intercept formThe slope-intercept form of the equation for a line is ...
y = mx +b . . . . . . . . where m is the slope and b is the y-intercept
This can be solved to find the y-intercept from a point on the line:
b = y -mx
Comparing this form to the given equation, you see the given line has a slope of m = -5.
Perpendicular lineThe perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line:
slope = -1/(-5) = 1/5
Y-interceptThe y-intercept of the desired line can be found using the equation for b above. The y-intercept of the line with slope 1/5 through point (x, y) = (20, -7) is ...
b = y -mx = (-7) -1/5(20) = -7 -4
b = -11

a stone is tossed into a lake, sending out circular ripples whose area is increasing at the rate of 520 ft2/sec. how fast is the radius increasing when the radius is 30 feet?
Answers
The radius is increasing fastly at a rate of 2.75 feet per second when it is already 30 feet.
Here, it has been told that the rate of change of the area with respect to the time is = 520 ft²/sec - (i)
This can also be written as = dA/dt (ii)
We need to find the rate of change of radius with respect to the time at 30 feet. This can be written as = dr/dt (iii)
We already know that the area of a circle can be found out using the formula = πr² (iv)
Differentiating equation (ii) with respect to time, we get -
= d(πr² )/dt
= π*(dr²/dt)
= π*(dr²/dr)*(dr/dt)
= π*(2r)*(dr/dt)
= dr/dt = (dA/dt)*(1/ π*2r)
Using the given values, we get -
= (dr/dt) = 520 / π*2*30ft
= (dr/dt) = 2.75 ft/sec
Henceforth, we find that the rate of change of the radius with respect to time at 30 feet is going to be 2.75 ft/sec.
