Answer:

Step-by-step explanation: However, say that the car loses 50% of its value every year. This means that if you originally bought a car for 2,000 dollars in 2015, in 2016 it would be world 2,000/2=1,000, 1,000/2=500 the year after that, and so on. We can try to put this into a linear function, but it's hard to put it into one equation because we're not subtracting or adding to the cost of the car by a specific amount each year. If we had our equation as y=-0.5*x+2000, this wouldn't work because it's adding to the original amount, not multiplying. However, if we used an exponential equation such as y=b(m^a), with y representing the end cost, b representing the starting cost, m representing the amount multiplied per year, and a representing the number of years. This works because we start with a value, and multiply it by an amount each year. Since 50%=0.5, we plug that into m to get y=2,000(0.5^a). Therefore, this works well here. If the minivan were to depreciate by 3,000 every year, starting at $29,248, this means that we first have to find out what we multiply by 29,248 by the first year to subtract 3,000. As, after one year, the value is 29,248-3,000=26,248, we have 26,248=29,248(m^1). Therefore, we can divide 29,248 by both sides to get around 0.9 as our answer form. Thus, our equation is y=29,248(0.9^a). This type of equation would not work if we subtracted an amount every year because we're not multiplying by the same amount then. For example, if a toy was valued at 3$ and gained a value of one dollar every year, we could multiply the toy by 4/3 the first year to get 4, but the next year we wouldn't get 5.

Answer:

There are 36 possible outcomes when two dice are rolled (6 outcomes for the first die and 6 outcomes for the second die). To find the probability that the sum of the two numbers on the dice will be greater than 9, we need to count the number of outcomes where the sum is greater than 9.

The possible outcomes where the sum is greater than 9 are (4,6), (5,5), (5,6), and (6,5), for a total of 4 outcomes. Therefore, the probability of getting a sum greater than 9 is 4/36 or 1/9.

Applying the leg rule, the length of BC in simplest radical form is: x = x = √390

The leg rule is used to find missing lengths in a right triangle when an altitude intersects the hypotenuse and form segments.

The leg rule is given as:

Hypotenuse / leg = leg / part

Thus, using the image given, we have:

Hypotenuse (AC) = 65

Part (DC) = 6

Leg = x

Plug in the values:

65 / x = x / 6

Cross multiply:

x * x = 6 * 65

The account's total value is $498,174.72.

The total interest paid is $174,174.72.

We can utilize the calculation for the future value of a compound interest annuity to resolve this issue:

FV = P*(((1 + r/n)(n*t))-1) / (r/n).

where

When we enter the values, we obtain:

FV = 600 * (((1 + 0.12/4)^(4*60)) - 1) / (0.12/4) = 498,174.72

After the 60th deposit, the account's total value is $498,174.72.

We can deduct the total amount deposited from the account's total value to calculate the cumulative interest:

Added interest is calculated as follows: FV - (P * t * n) = 498,174.72 - (600 * 60 * 4) = 174,174.72

Therefore, the total interest paid is $174,174.72.

Answer: The cost of a large pizza with 2 toppings depends on the pizza place. Let's say the cost is $15 per pizza, and each additional topping costs $2.

Let t be the number of toppings Anna has on her pizza. Then, the total cost of her pizza can be expressed as:

Total cost = $15 + $2t

Since Anna has 2 toppings on her pizza, we can substitute t = 2:

Total cost = $15 + $2(2)

Total cost = $15 + $4

Total cost = $19

Therefore, the total cost of Anna's pizza with 2 toppings is $19.

Statement " There will be 5 dots above 7" is true. Therefore, option D is the correct answer.

A line plot is an effective way to visualize and compare data in a table. In this case, the line plot would show the total number of people on each team, with dots representing the values.

The greatest value in the table is 11, but this would not be represented with a dot in the line plot. There will be 11 dots in total, representing the 11 teams listed in the table.

There will be 4 more dots above 7 than above 8, since there are 4 teams with 7 people on each team and only 3 teams with 8 people on each team.

The area of the given trapezoid is 270 square units.

A trapezoid is a four-sided geometric shape that has two parallel sides (called the bases) and two non-parallel sides (called the legs). The area of a trapezoid is the amount of space inside the shape and can be calculated using the formula:

A = (a + b)h/2

The number of chickens and pigs the farmer saw on the field are 37 and 16 respectively.

Let

Number of chickens = x

Number of pigs = y

The length the one-inch pipe should be cut to make a flute with a lowest desired note of 523.25 Hz, based on the acoustic length formula is 12.9 inches

The acoustic length is the length obtained from the sum of  the bore length and the corrections at the foot and the sound hole.

The frequency of the lowest note = 523.25 Hz

Whereby the frequency of the lowest note = The fundamental frequency

The acoustic length formula for finding the length of the pipe, L, can be presented as follows;

L = (v/(2·f)) × √(1 + 4·A²/v²)

Where;

L = The length of the pipe

f = The frequency = 523.25 Hz

A = The cross-sectional area of the pipe = π × 1.315²/4 ≈ 1.36 in²

v = The speed of sound ≈ 343 m/s ≈ 13503.9 in/s

L = (v/(2·f)) × √(1 + 4·A²/v²)

L = (13503.9/(2×523.25)) × √(1 + 4×1.26²/13503.9²) ≈ 12.9

The y-intercept of the line is 2.

In the equation y = 9x + 2, x and y are variables that represent the coordinates of any point on the line.

To find the Y-intercept, we need to find the value of y when x equals 0.

When x equals 0, the equation becomes:

y = 9(0) + 2

Any number multiplied by 0 is 0, so the first term drops out and we are left with:

y = 0 + 2

Which simplifies to:

y = 2

Therefore, when x equals 0, y equals 2. This means that the point (0, 2) is on the line. In other words, the line intersects the y-axis at y = 2, which is the Y-intercept of the line.

Huai's monthly payment for the community college loan is $89.72 and $235.35.

To calculate the monthly payment for each loan, we need first to calculate the total amount borrowed and the total interest paid for each loan.

For the first loan

Total amount borrowed = $3700

Total interest paid = $3700 x 0.068 x (4 + 4/12 + 3/12) = $1,271.12

Total amount repaid = $3700 + $1,271.12 = $4,971.12

To find the monthly payment, we can use the formula for a loan payment

P = (r(PV))/(1-(1+r)⁻ⁿ)

Where P is the monthly payment, r is the monthly interest rate, PV is the present value of the loan, and n is the total number of payments.

For the first loan, r = 0.068/12, PV = $3700, and n = 48 (4 years x 12 months/year). Substituting these values into the formula, we get

P = (0.068/12 * $3700)/(1-(1+0.068/12)⁻⁴⁸) = $89.72

Therefore, the monthly payment on the first loan is $89.72.

For the second loan

Total amount borrowed = $12,000

Total interest paid = $12,000 x 0.074 x (3/12) = $222.00

Total amount repaid = $12,000 + $222.00 = $12,222.00

The second loan was acquired 2 years after the first, so the total repayment period is 5 x 12 - 2 x 12 - 3 = 51 months.

Using the same formula as before, but with r = 0.074/12, PV = $12,000, and n = 51, we get

P = (0.074/12 * $12,000)/(1-(1+0.074/12)⁻⁵¹) = $235.35

Therefore, the monthly payment on the second loan is $235.35.
