determine the constant rate of change (slope) of the linear function. a high school basketball team notices that attendance at its games changes at a constant rate based on the number of losses the team has suffered. when the team had lost seven games, 295 people attended the next game. when the team had lost 13 games, 199 people attended the next game.
The team loses 20 people/audience with each loss.
The slope formula defines to the formula used to calculate the steepness of a line and determines how much it's inclined. To calculate the slope of the lines, the x and y coordinates of the points lying on the line can be used.
The formula to calculate slope is:
m = (y2 - y1)/(x2 - x1) = Δy/Δx
When the team lost eight games, 295 people attended the next game.
When the team lost 13 games, 199 people attended the next game.
Slope = 295-199/8-13
slope=100/-5
slope=-20
Therefore, the team loses 20 people/audience with each loss.
And the attendance loss is 20 times as great as the number of games lost/losses

What is the width of a rectangle if the area is 7 and 7/8and the length is 1 and 3/4?
Answer:
4.5
Step-by-step explanation:
To find the width of the rectangle, you must divide the area by the length.
7 and 7/8 divided by 1 and 3/4 = 4 1/2
The width of the rectangle is 4 1/2 or 4.5
check:
4 1/2 x 1 3/4 = 7 7/8
Answer:
4.5
Step-by-step explanation:
First, think back to literal equations in Algebra 1 or 2.
The formula for the area of a rectangle is:
\(a=lw\)
Fill in the variables that we know and solve.
\(7\frac{7}{8} =(1\frac{3}{4})w\)
Divide everything by (1 and 3/4)
\(\frac{\frac{63}{8}}{\frac{7}{4}}=w\)
Simplify:
\(w=\frac{9}{2}=4.5\)
w=4.5
Find the slope from the table.
Answer:
m=0
Step-by-step explanation:
the slope is calculated using two points on the line and the formula
m = (y2 - y1) ÷ (x2 - x1)
where
x1 and y1 are the coordinates of point 1
x2 and y2 are the coordinates of point 2
for example, you can take
point 1 = (x1;y1) = (-2;3)
point 2 = (x2;y2) = (-1;3)
then your slope is
m = (3 - 3) ÷ (-1 - (-2)) = 0
notice that x1 is always at the left of x2 on the x axis
and it makes sense that your slope is 0 because for each x your y is the same

On a given day, the flow rate F (cars per hour) on a congested roadway is
F= 3600v/(22+0.07v^2)
where v is the speed of the traffic in miles per hour. What speed will maximize the flow rate on the road?
Answer:
about 17.7 mph
Step-by-step explanation:
You want the value of v that maximizes F(v) = 3600v/(22+0.07v²).
DerivativeThe derivative of F is ...
\(F'(v)=\dfrac{3600(22+0.07v^2)-3600v(0.14v)}{(22+0.07v^2)^2}\)
MaximumThe derivative is zero at the maximum. This is the case when the numerator is zero:
3600(22 +.07v² -.14v²) = 0
.07v² = 22
v = √(22/0.07) ≈ 17.728
Flow rate is maximized at a speed of about 17.7 miles per hour.
Find the future value of an annuity due with a monthly payment of $300 at 6% interest compounded
monthly for 10 years.
O $4117.46
O $49163.80
O $49409.62
$52113.63
O $52374.20
O $109,163.80
Answer: The future value of an annuity due with a monthly payment of $300 at 6% interest compounded monthly for 10 years can be calculated using the formula:
FV = PMT * ( ( (1 + r)^n - 1) / r) * (1 + r)
where PMT = $300, r = 6%/12 = 0.05, and n = 10 years * 12 months/year = 120 months.
Substituting these values into the formula, we get:
FV = $300 * ( ( (1 + 0.05)^120 - 1) / 0.05) * (1 + 0.05)
FV = $300 * ( ( 1.05^120 - 1) / 0.05) * 1.05
FV = $300 * ( ( 2.704813829421526 - 1) / 0.05) * 1.05
FV = $300 * ( 1.704813829421526 / 0.05) * 1.05
FV = $300 * 34.09627658843153 * 1.05
FV = $52,113.63
Therefore, the future value of the annuity due is $52,113.63.

Suppose there is a pile of quarters, dimes, and pennies with a total value of $1.08
A) How much of each coin can be present without being able to make change for a dollar?B) Explain why $1.19 is the greatest amount of money it is possible to have without being able to make change for a dollar.
Answer:
a)
if 1 quarter = $ 0.25
1 dime = $ 0.10
1 penny = $ 0.01
so to make the total of $1.08 and its is also required to calculate the number of each coins present without being able to make change for a dollar
therefore we say;
1 Quarter + 8 dimes + 3 penny
: ( 1 × 0.25 ) + ( 8 × 0.10 ) + ( 3 × 0.01 )
: 0.25 + 0.80 + 0.03 = $ 1.08
b)
Now if you have a 4 Quarters, you have change for $1.
If you have 5 dimes, you have change for 2 Quarters.
If you have nickel; one of those can combine with 2 dimes to have a change for a Quarter.
If you have 5 pennies, you have enough change for 1 nickel
Therefore
(4-1)×0.25 + (5-1)×0.1 + (0×0.05) + (5-1)×0.01 = x
(3 × 0.25) + ( 4 × 0.1) + 0 + ( 4 × 0.01) = x
x = 0.75 + 0.4 + 0.04
x = $ 1.19

provided.
_______
Answer:
120
Step-by-step explanation:
In order to round to the nearest whole number, we need to figure out how to do that first. First, we start with the last number and see if it can round up the number to its left. It can do this if it is 5 or more:
0 ≤ 5, so it cannot round 2 any higher.
2 ≤ 5, so it cannot round 4 any higher.
4 ≤ 5, so it cannot round 0 any higher.
So, in conclusion, we have 120.

Answer:
I would say D. There is no logical explanation for the final answer but there is for everything else.
For A: Makes sense because 3x-2 are in parenthesis outside a number so you can multiply.
For B: Makes sense because you are allowed to add/subtract like terms but in this case only subtracting would make sense, (which is what they did) since you want to get all the like terms on one side.
For C: Makes sense because you are trying to simplify the equation, and they are both like terms (they are both numbers that have no letter attached to them) and they are on the opposite side making them able to be simplified.
For D: No idea what the point is.

Answer:
positive and odd
Step-by-step explanation:
If a is a negative odd number, then a² can't be negative, because a number squared is always positive.
I'll illustrate this with an example.
Let's choose -7 as an example. Instead of a.
-7² = 49
So we see that the result is positive & odd.

We have,
To find the product of 7 x 63 using the distributive property, we can break down 63 as the sum of its factors, such as 60 and 3:
7 x 63 = 7 x (60 + 3)
Now, we can apply the distributive property by multiplying 7 to each term inside the parentheses:
7 x (60 + 3) = 7 x 60 + 7 x 3
Simplifying further:
7 x 60 + 7 x 3 = 420 + 21
