Imagine a friend ask to borrow $100 and agrees to pay you back in one month. You agree and in one month pays you back. Do you lose money
Answer:
It depends on whether you are accounting for inflation. If not taking that into account, you do not lose money because your friend pays you the full amount back.
find the slope (4,4) (4,9)
Answer:
Undefined
Step-by-step explanation:
Slope form:
m (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (4 , 4)
(x₂ , y₂) = (4 , 9)
Plug in the corresponding numbers to the corresponding variables.
m = (9 - 4)/(4 - 4)
Simplify
m = (5)/(0)
m = undefined
Undefined is your answer, for there cannot be a 5/0. You cannot have 5 parts of nothing.

A ball is dropped from the top of a building. the height of the ball after x bounces can be represented by the expression 40(0.75)^x.
What does the in the expression 40 represent??
Answer:
I believe 40 is the height from which the ball was dropped
In the expression \( 40(0.75)^x \), the number 40 represents the initial height from which the ball is dropped. This initial height refers to the height of the ball above the ground before it experiences any bounces.
The expression itself describes a geometric sequence where the height of the ball after each bounce is a certain fraction of the height from the previous bounce. In this particular case, after each bounce, the ball reaches a height that is 75% (or 0.75 times) of the height of the previous bounce.
To break it down further:
- \( 40 \) is the initial height (in meters, feet, or another unit of measurement) where the ball was dropped from the top of the building.
- \( 0.75 \) is the common ratio, representing the fact that the ball loses 25% of its height with each bounce. It means that the ball only reaches 75% of the height it reached after the previous bounce.
- \( x \) is the number of bounces.
So, after the first bounce (when \( x = 1 \)), the height of the ball would be \( 40 \times 0.75 \). After the second bounce (when \( x = 2 \)), the height would be \( 40 \times 0.75^2 \), and so on for each subsequent bounce, following the pattern of a geometric sequence.

If ƒ(x) = 2x, then ƒ -1(x) =

½x
x - 2
Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):
[tex]f(x)=2x[/tex]
You need to:
Substitute [tex]f(x)=y[/tex] into the function:
[tex]y=2x[/tex]
Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:
[tex]\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x[/tex]
Now, replace "x" with "y" and replace "y" with "x":
[tex]\frac{x}{2}=y[/tex]
Therefore, substituting [tex]y=f^{-1}(x)[/tex] you get:
[tex]f^{-1}(x)=\frac{x}{2}[/tex] or [tex]f^{-1}(x)=\frac{1}{2}x[/tex]

Write an addition equation or a subtraction equation to describe the diagram
The addition equation or a subtraction equation to describe the diagram is (-9)—(-4) = -13
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a line graph shown in the picture.
The small arrow represents the length of 4 but as it is indicating negative direction, so we take -4
Similarly, the big arrow represents the length of 9 as it is indicating negative direction, so we take -9
The sum of the lengths:
(-9)—(-4) = -13
Thus, the addition equation or a subtraction equation to describe the diagram is (-9)—(-4) = -13

given h(x)=(3x-4), f(x)=(-7x+2), g(x)=(9x+1), which of the following is equivalent to 2x+3?
The function 2x + 3 is equivalent to g(x) + f(x) if the g(x) = (9x + 1) and f(x) = (-7x + 2)
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
h(x) = (3x - 4)
f(x) = (-7x + 2)
g(x) = (9x + 1)
Find h(x) + g(x):
= (3x - 4) + (9x + 1)
= 12x -3
Find g(x) + f(x):
= (9x + 1) + (-7x + 2)
= 2x + 3
Thus, the function 2x + 3 is equivalent to g(x) + f(x) if the g(x) = (9x + 1) and f(x) = (-7x + 2)

A local clothing shop is marking down all of its summer clothes by 75%. sarah would like to purchase a swimsuit that is originally priced at $80. when she gets to the register, she signs up for a loyalty cars that saves her an additional 10%. how much did she spend on the swimsuit and what total percent did she receive off?
a. Find the markdown price of the swimsuit.
b. Then, find the markdown of the loyalty card.
c. Subtract to find the final price.
Answer:
$18.00
Step-by-step explanation:
75% of 80$ is 60$ .
80$-60$=20$
10%of20$=2$
20$-2$=18$
18$
She spend $18 on the swimsuit and she gets total 77.5 percent off.
Given local clothing shop is marking down all of its summer clothes by 75%.
And Sarah would like to purchase a swimsuit that is originally priced at $80.
So, the markdown price of swimsuit will be ( $80 - 75 % of $80).
Now 75% of $80 is equals to $60.
So the markdown price of swimsuit will be ($80 - $60) or $20.
Again, when she gets to the register, she signs up for a loyalty cars that saves her an additional 10%.
So 2% of $20 dollar will be $2.
Now the final markdown price of swimsuit will be ($20-$2) or $18 .
Total discount she get is of ($80 - $18) or $62.
The percent amount she gets off = [tex]\frac{62}{80} \times100%[/tex] %.
=[tex]0.775 \times100[/tex]%.
[tex]=77.5[/tex]%.
She spend $18 on the swimsuit and she gets total 77.5 percent off.

A piece of wood that is 3/4 meter long is being cut into smaller pieces that are each 1/10 meter long.Which equation could be solved as the first step to find the number of pieces,n, that can be made?
Since the smaller pieces are all equal.
Then, X1=X2=X3...=1/10.
Therefore, the sum of the whole pieces should give you 3/4 back.
X1+X2+X3...=3/4
Therefore, (3/4÷n)=1/10
where n is the number of all the pieces.

m - slope
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (-3, -1) and (1/2, 2). Substitute:
[tex]m=\dfrac{2-(-1)}{\frac{1}{2}-(-3)}=\dfrac{3}{3\frac{1}{2}}=\dfrac{3}{\frac{7}{2}}=3\cdot\dfrac{2}{7}=\dfrac{6}{7}\\\\y-(-1)=\dfrac{6}{7}(x-(-3))\\\\y+1=\dfrac{6}{7}(x+3)}[/tex]
Convert to the standard form Ax + By = C:
[tex]y+1=\dfrac{6}{7}(x+3)[/tex] multiply both sides by 7

The circumference of heileen’s basketball is 30 inches. What is the approximate diameter of the basketball?
Answer:
9.55 in
Step-by-step explanation:
The formula for the circumference of a circle (or the circum. of a basketball) is C = πd, where d is the diameter.
Here C =30 in = πd, so
d = (30 in) / π
= 9.55 in, approx.
Answer:
d = 9.554 inches.
Step-by-step explanation:
Formula
C = 2*pi*r
r = the radius
C = the Circumference.
Givens
Circumference = 30 inches.
pi = 3.14
Solution
C = 2*pi * r
30 = (2*r) * 3.14 (you'll see why I've done that in a minute. Divide by pi.
30/3.14 = 2*r
9.554 = 2r
The diameter of the basketball = 2 * radius. So the answer for the diameter = 9.554 inches.
if area of a circle is equal to volume of sphere with equal radii, find the radius.
Answer:
r = 3/4
Step-by-step explanation:
Area of circle = Volume of sphere.
pi*r^2 = 4/3 pi r^3 Divide by pi r^2
1 = 4/3 r Divide by 4/3
1//4/3 = 4/3 r / 4/3

If it rains tomorrow, the probability is 0.6 that John will practice his cello. If it does not rain tomorrow, there is only a 0.4 chance that John will practice. Suppose the chance of rain tomorrow is 70%.
What is the probability that John will practice his cello?
The final probability is the weighted average of the playing probabilities calculated over the possible weather options:
P(john practices cello; given that it rains) * P(it rains) +
P(john practices cello; given that it does not rain) * P(it does not rain) =
0.6 * 0.7 + 0.4 * 0.3 = 0.54
The probability is 54%
The probability that John will practice his cello is 54%.
Given information:If it rains tomorrow, the probability is 0.6. If it does not rain tomorrow, there is only a 0.4 chance. And, the chance of rain tomorrow is 70%.

Step-by-step explanation:
Slope of the line =-5
To get point slope form of the line , we use the point that passes through the line. LEts pick the point (2,-8)
Point slope form of a line is
[tex]y-y_1=m (x-x_1)[/tex]
(x1,y1) is (2,-8) and slope m = -5

What is the probability of choosing a number from 1-25 that is a multiple of 4
Answer:
6/25, or 0.24
Step-by-step explanation:
There are 25 numbers from which to choose, each equally likely to be chosen.
Multiples of 4 that are between 1 and 25 are {4, 8, 12, 16, 20, 24}
There are 6 such multiples of 4, out of 25 numbers total.
Thus, the probability of choosing a number from 1-25 that is a multiple of 4 is 6/25, or 0.24.
