D.12
Answers
12 is its average rate of change from x = 2 to x = 10.
What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Given the function defined by y = x^2
now,
its average rate of change from x = 2 to x = 10,=
=10^2-2^2/10-2
=100-4/8
96/8
=12
Hence, 12 is its average rate of change from x = 2 to x = 10.

Answer:
(F-G)(x) = -1
Step-by-step explanation:
The notation (F - G)(x) means to subtract each function when x = 6. According to the sets when x = 6 then F is (6,8) and G is (6,9). To subtract the functions, subtract their output values. (F-G)(x) = 8 - 9 = -1.

James runs 8 laps in 14 minutes. How many laps can he run in one hour and ten minutes?
Answers
Answer: Don't come at me if I'm wrong, but I believe it's 40 laps.
Step-by-step explanation:
First, you need to figure out how many laps James runs in 1 minute and you can do this by dividing the number of laps and minutes (8 laps/14 minutes). This should give you 4/7 laps/minute.
Next, you figure out how many minutes 1 hour and 10 minutes is (just to make things easier) 1 hour and 10 minutes = 70 minutes
Then, you multiple 4/7 and 70 and you get 40 laps.
Answer:
40 laps
Step-by-step explanation:
I just put this into a proportion
so basically i just did 8/14 = ?/70
Then i just worked it like any other problem
8 x 70 then divide 14 and i got 40.
so James ran 40 laps in one hour and tens minutes
NOTE that i turned one hour and ten minutes into minutes

An item is regularly priced at $60. It is on sale for 40% off the regular price. What is the sale price?
Answers
Answer: The sale price is $36.
Step-by-step explanation:
40% ÷ 100 = 0.4
0.4 × $60 = $24
$60 - $24 = $36
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
If there is an off of 40% on an item that cost $60.
The regular price of the item is $48.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
105 = 10/100 = 1/10
Example:
50% of 40 is 20.
50/100 x 40 = 20
25% of 100 is 25.
25/100 x 100 = 25.
We have,
Regular price = $60
Off = 40%
Sale price:
= 60 - (40% of 60)
= 60 - (40/100 x 60)
= 60 - (2/5 x 60)
= 60 - (2 x 12)
= 60 - 24
= $48
Thus.
If there is an off of 40% on an item that cost $60.
The regular price of the item is $48.

Markups The depth of water in a pond increases by 3% after a heavy rain. If the average depth of the water was 8.3 feet, what is the new depth?
Answers
Answer: 8.55 feet
Step-by-step explanation:
We should equal the average depth to 1, so if it raises 3%, it raises 0.03. Simply add the original (1) plus what it rose (0.03) and multiply the original by that, so 8.3 × 1.03 = new depth. The result is 8.549 feets.

Answer:
a. y = -x + 7
Step-by-step explanation:
The line with equation y = x - 5 has slope = 1.
A perpendicular to a line has the opposite reciprocal slope of the line, so a perpendicular to the given line has slope -1.
y = -x + b
To find the value of b, we plug in the given point for x and y and solve for b.
y = -x + b

b = 7
y = -x + 7

Your school band is performing a concert. Tickets cost $3 for students and $5 for adults. A total of 125 people attended the concert for a total ticket sales of $475. Write and solve a system of equations to find the number of students and adults that attended the concert. Make sure to write your answer in a complete sentence.
Answers
Given :
Tickets cost $3 for students and $5 for adults.
A total of 125 people attended the concert for a total ticket sales of $475.
To Find :
The number of students and adults that attended the concert.
Solution :
Let, number of students and adults that attended the concert is x and y.
Mathematical equation of given conditions :
x + y = 125 ....1)
3x + 5y = 425 ....2)
Putting value of x from 1 to equation 2 is :
3( 125 - y ) + 5y = 425
375 - 3y + 5y = 425
2y = 50
y = 25
x = 125 - 25
x = 100
Therefore, number of students and adults that attended the concert is 100 ans 25 respectively.
Hence, this is the required solution.

The line segment joining the points ( 3,-4) and (1,2) is trisected at the points P and Q . If the coordinates of P and Q are (p , -2 ) and ( 5/3 , q ) respectively, find the values of p and q.
Answers
Answer:
P = 7/3 and q = 0
Step-by-step explanation:
The given parameters are;
The endpoints of the segment are, (3, -4) and (1, 2)
The points that trisect the given points are P and Q with coordinates (p, -2) and (5/3, q) respectively
Therefore, we have;
The first point of the trisection cuts 1/3 of the length from one point and the second point of the trisection cuts 2/3 of the length from the same point
The coordinates of P or Q = (3 - (3 - 1)/3, -4 - (-4 - 2)/3) = (7/3 , -2)
Therefore, given that the y-coordinate value of the derived point coincides with the y-coordinate value of the point P, (p, -2) and there is only one point with x = -2 on the line, we have that the coordinate of the point P is (p, -2) = (7/3 , -2)
∴ P = 7/3
Similarly we have the second point of the trisection, Q, given as follows;
We are already given the x-coordinate value of the point Q as the 5/3 in (5/3, q)
Point Q = (5/3, q) = (3 - 2×(3 - 1)/3, -4 - 2×(-4 - 2)/3) = (5/3 , 0)
Point Q = (5/3, q) = (5/3 , 0)
∴ q = 0.
