A flashlight shines straight up into the sky, 9 ft to the right of a tent located at the origin. For which values of A, B, and C will Ax+By=C represent the beam of light?
The values of A = 1, B = 0, and C = 9 would be Ax + By = C represent the beam of light.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
A flashlight shines straight up into the sky, 9 ft to the right of a tent located at the origin.
Given that the direction must be vertical, it should appear to have a consistent or constant x-coordinate.
Here Ax + By = C represents the beam of light.
So the required equation for a line is:
⇒ x = 9
Comparing the given equation, we get
Ax + By = C
Here A = 1, B = 0, and C = 9
Therefore, the values of A = 1, B = 0, and C = 9 would be Ax + By = C represent the beam of light.

Answer:
An exponent
Step-by-step explanation: So if we have 83, we want to multiply three 8s, or 8 * 8 * 8. A root is basically the opposite. We're trying to find the number that we multiply by itself a certain number of times to get the number under the radical sign.
Jerry bought 5 candy bars for $14.75. If the king size candy bars cost $3.75 and a regular size candy bar cost $1.75 , how many of each candy bar did he buy?

The scores on a statistics test had a mean of 81 and a standard deviation of 9. One student was absent on the test day and his score wasn't included in the calculation. If his score of 78 was added to the distribution of scores, what would happen to the mean and standard deviation?
A) Mean will increase, standard deviation will decrease.
B) Mean will increase, standard deviation will increase.
C) Mean will decrease, standard deviation will stay the same.
D) Mean will decrease, standard deviation will increase.
E) Mean will decrease, standard deviation will decrease.
Answer: E) Mean will decrease, standard deviation will decrease
Step-by-step explanation:
Initial mean = 81
Initial standard deviation = 9
New score = 78
Taking a look at the initial mean(averahe) score, which is 81 and the new score to be added to the initial scores, the initial average is greater than the new score. Hence, this will result in a decrease in the new mean score after adding the new score of 78.
Also, taking a look at the standard deviation which is 9, we can conclude that the variability in initial scores from the mean scores is high. However, the new score of 78 and the initial mean are very close, and tend to low variation. Hence, adding the new score will lead to a decrease in variability and hence a decrease in the value of standard deviation.

Step-by-step explanation:
1. divide using long division
put 2 outside and the 2100 inside
then from there 2 goes into 2 once so put that on top. Next 2 cant go into one so put a zero above the one. After that 2 goes into 10 5 times so put a 5 above the first zero in 2100. Lastly 2 goes into zero 0 times so put a zero above the second zero.

What is located at (–2, –2)?
A. Nicholas’s home
B. post office
C. school
D. grocery store
Answer:
B. The post office
youre welcome!
The place located at coordinates (-2, -2) is the post office.
Option B is the correct answer.
We have,
The coordinates are in the form of (x, y).
The coordinates of each location on the given graph are:
Nicholas’s home = (0, 0)
Post office = (-2, -2)
School = (3, 2)
Grocery store = (1, -1)
Thus,
The place located at coordinates (-2, -2) is the post office.

Find the distance between the following two points:
*
(-5,0) and (-2,-1)
Answer:
[tex]d = \sqrt{10}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(-2-(-5))^2+(-1-0)^2}[/tex]
[tex]d = \sqrt{(-2+5)^2+(-1)^2}[/tex]
[tex]d = \sqrt{(3)^2+1}[/tex]
[tex]d = \sqrt{9+1}[/tex]
[tex]d = \sqrt{10}[/tex]

2(u-1)-6= -5(-4u+4) -3u
Answer:
u = 4/5
Step-by-step explanation:
Expand
2u - 2 - 6 = 20u - 20 - 3u
Rearrange with like terms on either side
12 = 15u
u = 4/5
Answer:
u=4/5
Step-by-step explanation:
First, parentheses/multiply on both sides.
2u-2-6=20u-20-3u <--- two negatives make a positive
Next, add/subtract like terms.
2u-8=17u-20
Then, add 8 to both sides.
2u=17u-12
Finally, get "u" by itself. Subtract "17u" to both sides and then divide "-15" to both sides
-15u=-12
u=4/5
Question from the lawyer: "Dr. Expert, I only see a 70° angle here, Exhibit A. Kelly said that having this angle means you have a plane. From what I see, none of the definition of a plane say that an angle defines a plane. Explain how each definition proves that an angle defines a plane."

15. Definition 2: A line and a point not lying on the line.
Proof:
16. Definition 3: Two lines which intersect
Proof:
I need help with the proof :)
Answer:
14. Three points tat are not collinear
Three points that are not colinear consist of a line and a third point, therefore, joining all three points form a flat figure having a length and a width which is a two-dimensional flat figure or a plane
15. A line and a point not lying on the line
Like the example above, the joining of the points results in a two dimensional figure having a length and a width also known as a planar surface
16. Two lines which intersect at a point
Given two lines that intersect at a point, joining the other end point of the two lines results in the forming of a flat figure, that can be described in two dimensions also known as a planar surface or plane
Step-by-step explanation:
A plane in mathematics is a flat surface that has only two dimensions and extends infinitely in all directions
