What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.
Here,
Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.
So, to convert 40 meters to centimeters, we can multiply 40 by 100:
40 meters = 40 x 100

Kelly bought a new SUV for $28,000. She made a down payment of $11,000 and has monthly payments of $332.63 for 5 years. She is able to pay off her loan at the end of 36 months. Using the actuarial method, find the unearned interest and payoff amount.
The unearned interest and the payoff amount is $11,022.12 and $18,784.87 respectively
Given data ,
Kelly bought a new SUV for $28,000. She made a down payment of $11,000 and has monthly payments of $332.63 for 5 years.
She is able to pay off her loan at the end of 36 months.
Now , Total interest = (monthly payment x number of months) - loan amount
Total interest = ($332.63 x 60) - $17,000
Total interest = $19,957.80
Next, we need to calculate the interest that has already been paid over the first 36 months of the loan. We can use the formula:
Interest paid = (monthly payment x number of months) - (loan amount - down payment)
Interest paid = ($332.63 x 36) - ($28,000 - $11,000)
Interest paid = $8,935.68
The unearned interest is the difference between the total interest and the interest paid so far:
Unearned interest = total interest - interest paid
Unearned interest = $19,957.80 - $8,935.68
Unearned interest = $11,022.12
To find the payoff amount, we need to add the remaining principal balance to the unearned interest:
Payoff amount = remaining balance + unearned interest
To calculate the remaining balance, we can use the formula for the present value of an annuity:
Remaining balance = monthly payment x (1 - (1 + r)^-n) / r
Where r is the monthly interest rate and n is the number of remaining months. We can solve for r by using the total interest calculated earlier:
r = (Total interest / loan amount) / 12
r = ($19,957.80 / $17,000) / 12
r = 0.0986%
Using this interest rate and n = 24 (the remaining 24 months of the loan), we can calculate the remaining balance:
Remaining balance = $332.63 x (1 - (1 + 0.0986%)^-24) / 0.0986%
Remaining balance = $7,762.75
Payoff amount = $7,762.75 + $11,022.12
Payoff amount = $18,784.87
Hence , the interest is solved

Rounding to the nearest hundredth, the surface area of the regular hexagonal pyramid is approximately 663.2 square centimeters.
Step by Step Explanation:
The surface area of a regular hexagonal pyramid can be calculated using the formula:
Surface area = (1/2) x Perimeter of base x Slant height + Base area
To find the perimeter of the hexagonal base, we can use the formula:
Perimeter of hexagon = 6 x Length of one side
Since the base edge length is 8 centimeters, the length of one side of the hexagon is also 8 centimeters. Therefore, the perimeter of the hexagonal base is:
Perimeter of base = 6 x Length of one side = 6 x 8 = 48 centimeters
To find the base area of the pyramid, we can use the formula:
Base area = (3/2) x (Square root of 3) x (Length of one side)^2
Substituting the values, we get:
Base area = (3/2) x (Square root of 3) x (8)^2 = 96(sqrt(3)) square centimeters
Now we can substitute the values into the surface area formula:
Surface area = (1/2) x Perimeter of base x Slant height + Base area
Surface area = (1/2) x 48 x 15 + 96(sqrt(3))
Surface area = 360 + 96(sqrt(3)) square centimeters
A new television set was recently purchased for the common room in a Residence Hall for $451.50 including tax. If the tax rate is 5%, find the price of the television set before taxes.
Answer:
430
Step-by-step explanation:
Let's call the price of the television set before taxes "x".
The total cost including tax is $451.50, which is equal to x plus 5% of x (the tax). In other words:
x + 0.05x = $451.50
Simplifying the left side by factoring out x, we get:
1.05x = $451.50
Dividing both sides by 1.05, we get:
x = $430
Therefore, the price of the television set before taxes was $430.

if (-8,3) lies on the circle and its Center is (-4,3) find the radius
If (-8,3) lies on the circle and its Center is (-4,3) then, the radius of the circle is 4.
We know that the center of the circle is (-4, 3). Let's call the radius of the circle "r".
The distance between the center of the circle and the point (-8, 3) on the circle is equal to the radius "r".
Using the distance formula, we can find the distance between these two points;
d =√[(x2 - x1)² + (y2 - y1)²]
d = √[(-8 - (-4))² + (3 - 3)²]
d = √[(-8 + 4)² + 0²]
d = √[4²]
d = 4
Since the distance between the center of the circle and the point on the circle is equal to the radius, we have;
r = d = 4
Therefore, the radius of the circle is 4.

Step-by-step explanation:
(a) Lett be the time (in days) since the start of the experiment, and let
y be the amount of the substance at time t.
Write a formula relating y to t.
Use exact expressions to fill in the missing parts of the formula.
Do not use approximations.
y = ei
Answer: (a) The formula relating the amount of substance, y, to time, t, is given by:
y = y₀ * e^(-λ*t)
where y₀ is the initial amount of the substance, λ is the decay constant, and e is the mathematical constant approximately equal to 2.71828.
The half-life, T½, is related to the decay constant as:
T½ = ln(2)/λ
We are given that the half-life of the substance is 16 days, so we can solve for λ:
λ = ln(2)/T½ = ln(2)/16
Substituting this value of λ in the formula for y, we get:
y = 65.7 * e^(-ln(2)*t/16)
(b) To find the amount of substance present after 13 days, we substitute t = 13 in the formula for y:
y = 65.7 * e^(-ln(2)*13/16) ≈ 42.1
Rounding to the nearest tenth, we get y ≈ 42.1 g. Therefore, approximately 42.1 g of the substance will be present after 13 days.

What is the total percentage of the athletes who enjoy cycling?
9%
25.5%
55%
74.5%
Answer:
75%
Step-by-step explanation:
To determine the total percentage of athletes who enjoy cycling, we need to consider the percentages given in the problem.
According to the information provided:
55% of the team does not like to run.
Of those who do not like to run, 70% enjoy cycling.
Of those who enjoy running, 80% also enjoy cycling.
To calculate the total percentage of athletes who enjoy cycling, we need to consider the percentages from both branches of the tree diagram.
Percentage of athletes who do not like to run and enjoy cycling:
= (Percentage of athletes who do not like to run) * (Percentage of those who enjoy cycling within that group)
= 55% * 70% = 38.5%
Percentage of athletes who enjoy running and enjoy cycling:
= (Percentage of athletes who enjoy running) * (Percentage of those who enjoy cycling within that group)
= (100% - 55%) * 80% = 45% * 80% = 36%
Total percentage of athletes who enjoy cycling:
= Percentage of athletes who do not like to run and enjoy cycling + Percentage of athletes who enjoy running and enjoy cycling
= 38.5% + 36% = 74.5%
Therefore, the correct answer is:
74.5%

The value of angle JKN is 73°.
Given that the m ∠JKM = 106 degrees, m ∠LKM = 66, and KN bisects LKM.
So we need to find the value of ∠JKN,
So, using the angles addition postulate,
∠LKM = ∠LKN + ∠MKN
Therefore,
∠LKN = 66/2 [definition of bisector]
∠LKN = 33°
Again, using the angles addition postulate,
∠JKM = ∠JKL + ∠LKM
∠JKL = 106 - 66
∠JKL = 40°
Therefore,
∠JKN = ∠JKL + ∠LKN
∠JKN = 40 + 33

Bob wants to break the school record of scoring 30 points in his basketball game. He scored 13 points in the first half. How many two point baskets must Bob make in the second half to break the school record?
Bob needs to make at least 9 two-point baskets in the second half to break the school record of scoring 30 points in his basketball game.
To break the school record of scoring 30 points, Bob needs to score more than 30 points in his basketball game. Since he scored 13 points in the first half, he needs to score at least 17 points in the second half to break the record.
Let's assume that Bob makes x two-point baskets in the second half. Since each two-point basket contributes 2 points to his score, his total score from two-point baskets would be 2x.
Therefore, to break the school record, we need to solve the following inequality:
2x + 13 > 30
Subtracting 13 from both sides, we get:
2x > 17
Dividing both sides by 2, we get:

Beth pulls a slinky a distance of 24 inches from its equilibrium position and then releases it. The time for one oscillation is 2 seconds. Step 2 of 2 : Find the function in terms of t for the displacement of the slinky. Assume that the slinky is at its maximum displacement at t=0 . Also assume that the function includes no horizontal or vertical shifts.
The final function for slinky displacement is: 24 sin(t/2 - /2) d(t). This offers the displacement in inches as a function of time in seconds.
How to Solve the Problem?A sinusoidal function of the form: can be used to describe the slinky's displacement.
A sin(t + ) = d(t).
where A is the greatest displacement, is the angular frequency (2 divided by the period), and is the phase angle (starting phase).
We know the slinky's greatest displacement (amplitude) occurs at t=0, thus we have:
24 inches = d(0) = A sin()
We also know that the period is T=2 seconds because the time for one oscillation (i.e., one complete cycle) is 2 seconds. As a result, the angular frequency is:
ω = 2π / T = π radians/second
The phase angle can be calculated using the fact that the slinky is at its equilibrium position at t=T/4=0.5 seconds. At this time, the sine function's argument is:
= 2 / T = radians per second
The phase angle can be calculated using the fact that the slinky is at its equilibrium position (zero displacement) at t=T/4=0.5 seconds. At this time, the sine function's argument is:
ωt + φ = π/2
When we substitute the known values, we get:
π/2 + φ = 0.5π
φ = -π/2
As a result, the slinky's displacement function is:
A sin(t/2 - /2) = d(t).
We may utilize the information that the amplitude is 24 inches to calculate A:
A = |24| = 24
As a result, the final function for slinky displacement is:
24 sin(t/2 - /2) d(t)

5 years ago i was 5 times older then my son. in 8 years time i will be 3 times older then my son. how old am i today?
Answer:
70 , 18
Step-by-step explanation:
Keeping x as Father and y as son;
5 years ago Person X was 5 times older than Person y , so the equation will be:
x - 5= 5(y-5)
x = 5y - 20
simularily after 8 years , x will be 3 times older than y , so
x + 8 = 3(y + 8.)
I will now try to find y by equating value of x into y:
5y - 20 + 8 = 3y + 24
5y - 3y = 24 + 20 - 8
2y = 44 - 8 = 36
y = 18
so x will be = 5 (18) - 20.
x = 90-20 = 70 years.
therefore father is 70 years , and son is 18 years old.

What is the output for x = -1
Answer:
f(-1) = 16
Step-by-step explanation:
"output" and the f(x) setup just means to plug in -1 in place of x and calculate.
For the function f(x) = 12(3/4)ˣ you have to already know that once you put that -1 in place of x that the -1 power only goes to the 3/4, not the 12 and also what to do with a negative exponent.
Exponent rules are just shortcuts. The shortcut to know here is that the -1 exponent will flip the 3/4 over and make it 4/3 (there are math reasons for this, it's not random. But that's how it works)
So now you have
f(-1) = 12(3/4)⁻¹ which becomes
f(-1) = 12(4/3)
Now you need to know how to multiply with fractions. Here you have a whole, big number times a fraction, which is:
"big num×top all over bottom"
So multiply the 12 times the 4 and put it over the 3
f(-1) = 48/3 = 16
(or you can "cancel" the 12 with the 3 and get 4×4, which is 16, so it comes out the same)
[SKIP TO HERE IF YOU DON'T CARE WHY]
f(x) = 12(3/4)ˣ
f(-1) = 12(3/4)⁻¹
f(-1) = 12(4/3)
f(-1) = 16
