Answer:

An equivalent equation would be 2x = 4.

Step-by-step explanation:

Expanding the brackets and simplifying, we get:

8x + 4 - 3x + 6 = 20

Combining like terms, we get:

5x + 10 = 20

Subtracting 10 from both sides, we get:

5x = 10

Dividing both sides by 5, we get:

x = 2

So an equivalent equation would be 2x = 4.

Answer: $34,828.59

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r)^t

where:

P = the principal (in this case, $14,275)

r = the annual interest rate (6%, or 0.06 as a decimal)

t = the number of years (18)

Plugging in the values we know, we get:

A = $14,275(1 + 0.06)^18

A = $14,275(1.06)^18

A = $34,828.59 (rounded to the nearest penny)

Therefore, the value of the investment after 18 years, rounded to the nearest penny, is $34,828.59

Answer:

Answer: $31,920.

Step-by-step explanation:

The banker's rule is a method used by lenders to determine the maximum amount of money that a borrower can afford to repay. According to this rule, the maximum amount of money that Lee can afford to borrow is determined by multiplying his annual income by a factor of 0.28.

Using this rule, the amount that Lee can afford to borrow can be calculated as:

Maximum affordable monthly payment = 0.28 x monthly income

Maximum affordable monthly payment = 0.28 x (24700/12)

Maximum affordable monthly payment = 0.28 x 2058.33

Maximum affordable monthly payment = 576.66

Therefore, Lee can afford to make monthly payments of up to $576.66. To calculate the total amount he can borrow, we need to determine the total cost of the loan, including principal and interest.

Assuming a 5-year loan with an interest rate of 4%, the total cost of the loan can be calculated using an online loan calculator or spreadsheet software.

Plugging in the numbers, the total amount that Lee can borrow is approximately $31,920.

It's important to note that this calculation is based on the banker's rule and assumes that Lee has no other debt obligations. Actual loan approval and loan amounts may vary depending on other factors such as credit score, debt-to-income ratio, and other lender-specific requirements.

The exterior angle at K in triangle HJK is 139°, whereas the exterior angle at J is 53°. Shortest side is JK.

We know that the sum of exterior angles of a triangle is 360°. So,

Exterior angle at K + exterior angle at J + exterior angle at H = 360°

139 + 53 + exterior angle at H = 360

exterior angle at H + 192 = 360

exterior angle at H = 360 - 192

exterior angle at H = 168°

Now, we will calculate the interior angles of triangle HJK. We know that exterior and interior angles are supplementary and makes a sum of 180 degree.

Interior angle K + exterior angle K = 180

Interior angle K + 139 = 180

Interior angle K = 180 - 139 = 41°

Interior angle H + exterior angle H = 180

Interior angle H + 168 = 180

Interior angle H = 180 - 168 = 12°

Interior angle J + exterior angle J = 180

Interior angle J + 53 = 180

Interior angle J = 180 - 53 = 127°

A triangle's shortest side is always opposite the smallest angle. So, in this question the smallest angle is ∠H and the side opposite to it is KJ, hence KJ is the shortest side.

First, let's calculate the monthly interest rate (i), which is the APR divided by 12 months:

i = APR / 12 months

i = 5.3% / 12

i = 0.00442 or 0.442%

Next, let's calculate the number of months (n) for the mortgage, which is 15 years multiplied by 12 months:

n = 15 years x 12 months/year

n = 180 months

Now, let's calculate the monthly payment (PMT) using the following formula:

PMT = P * i / [tex](1 - (1 + i)^(-n)[/tex])

where P is the principal amount, i is the monthly interest rate, and n is the number of months.

PMT = $325,000 * 0.00442 / (1 - [tex](1 + 0.00442)^(-180)[/tex]

PMT = $2,613.67 (rounded to the nearest cent)

Now, let's create the amortization table for the first two months:

Month | Payment | Interest | Principal | Remaining Balance

1 | $2,613.67 | $1,431.25 | $1,182.42 | $323,817.58

2 | $2,613.67 | $1,428.60 | $1,185.07 | $322,632.51

For each month, the Payment column shows the fixed monthly payment, the Interest column shows the calculated interest based on the remaining balance multiplied by the monthly interest rate, the Principal column shows the portion of the payment that goes towards reducing the principal, and the Remaining Balance column shows the remaining balance after subtracting the principal payment from the previous remaining balance.

The amortization table will continue in this manner for the remaining months until the mortgage is paid off.

The interest and principal amounts for the first payment are:

Interest = $325,000 * 0.0044167 = $1,426.25

Principal = $2,549.67 - $1,426.25 = $1,123.42

Balance = $325,000 - $1,123.42 = $323,876.58

For the second payment, we start with the new balance of $323,876.58 and apply the formulas again:

Interest = $323,876.58 * 0.0044167 = $1,420.47

Principal = $2,549.67 - $1,420.47 = $1,129.20

Balance = $323,876.58 - $1,129.20 = $322,747.38

To complete the two-month amortization table, we need to calculate the monthly payment, as well as the principal and interest amounts for each payment.

The formula for calculating a fixed-rate mortgage payment is:

[tex]Payment = P * r * (1 + r)^n / [(1 + r)^n - 1][/tex]

Where:

P = Principal amount borrowed

r = Monthly interest rate

n = Total number of payments

First, let's calculate the monthly interest rate.

Since the APR is an annual rate, we need to divide it by 12 to get the monthly rate:

Monthly interest rate = 5.3% / 12 = 0.0044167

Next, we need to calculate the total number of payments.

Since this is a 15-year mortgage, and we're completing a two-month amortization table, the total number of payments is:

Total number of payments = 15 years * 12 months per year = 180

Number of payments for two months = 2

Now we can plug these values into the formula to calculate the monthly payment:

Payment = [tex]$325,000 * 0.0044167 * (1 + 0.0044167)^180 / [(1 + 0.0044167)^180 - 1][/tex]

= $2,549.67

So the monthly payment is $2,549.67

Now we can use this value to complete the two-month amortization table:

Payment Interest Principal Balance

Month 1 $1,426.25 $1,123.42 $323,876.58

Month 2 $1,420.47 $1,129.20 $322,747.38

To calculate the interest and principal amounts for each payment, we use the following formulas:

Interest = Balance * Monthly interest rate

Principal = Payment - Interest

Balance = Balance - Principal

We start with the initial balance of $325,000 and apply the formulas for each payment.

The interest and principal amounts for the first payment are:

Interest = $325,000 * 0.0044167 = $1,426.25

Principal = $2,549.67 - $1,426.25 = $1,123.42

Balance = $325,000 - $1,123.42 = $323,876.58

For the second payment, we start with the new balance of $323,876.58 and apply the formulas again:

Interest = $323,876.58 * 0.0044167 = $1,420.47

Principal = $2,549.67 - $1,420.47 = $1,129.20

Balance = $323,876.58 - $1,129.20 = $322,747.38

The total distance that Dr. Price travels during her observations is 2567.1 meters, and the distance between Location D and the point halfway between Locations B and C is 1,317.125 meters.

First, we can look at the distances between each location. The table tells us that the difference between Location A and Location B is 203.15 meters. The difference between Location B and Location C is 1686.55 meters, and the difference between Location C and Location D is 474.25 meters.

To calculate the total distance that Dr. Price travels, we need to add up the distances for each part of her journey. First, she travels from Location A to Location B, a distance of 203.15 meters. Then she returns to Location A, so she travels the same distance back, for a total of 406.3 meters. Next, she descends from Location A to Location C, a distance of 1686.55 meters. Finally, she descends further to Location D, a distance of 474.25 meters. Adding up these distances, we get a total distance of 2567.1 meters.

For the second part of the question, we need to find the distance between Location D and the point halfway between Locations B and C. To do this, we first need to find the depth at the midpoint between Locations B and C. We can do this by taking the average of the depths for Locations B and C, which gives us -1,941.875 meters.

Next, we can calculate the distance between Location D and the midpoint between B and C. This is simply the difference in depth between Location D (-3,259 meters) and the midpoint (-1,941.875 meters), which gives us a distance of 1,317.125 meters.

The values of lengths are:  AE = 30, GF = 10, GD = 5 for the given ΔABC.

Point at which all three medians of a particular triangle meet is called as a centroid. Median also called as a line segment which connects the vertex of a triangle to the midpoint.

Since G is the centroid of ΔABC, it divides each median in the ratio  of 2:1. That is,

AG:GE = 2:1,     BG:GF = 2:1,     CG:GD = 2:1

First, we know, AG/GE = 2/1         (given, AG = 20)

20 / GE = 2/1

GE = 10

So, given in the median of ΔABC is,

AE = AG + GE      (put the values)

AE = 20 + 10

AE = 30

Now, we can use the fact that BG:GF = 2:1 to find the length of GF:

we know, BG/GF = 2/1         (given, BF = 30 = BG + GF)

BG = 2GF

(BF - GF) = 2GF                     (here, BG = BF - GF)

30 - GF = 2GF

GF = 10

Now, we can use the fact that CG:GD = 2:1 to find the length of GD:

we know, CG/GD = 2/1         (given, CG = 10)

10 / GD = 2/1

GD = 5

V = (4/3)πr^3 = (1/6)πd^3,

where V is the volume, r is the radius, and d is the diameter.

Taking the derivative with respect to time t, we get

dV/dt = (1/2)πd^2 (dd/dt),

where dd/dt is the rate of change of diameter.

We are given that dV/dt = 2.8 ft^3/min and d = 1.5 ft, so we can solve for dd/dt

We need to know the prism's dimensions in order to determine its lateral and total surface area for a rectangular base prism. The rectangular prism's length, width, and height are assumed to be L, W, and H, respectively.

The sum of the areas of the rectangular prism's four lateral faces determines its lateral surface area. Since every sidelong face is a square shape with a level of H and a width of one or the other L or W, the parallel surface region is given by:

Lateral Surface Area = 2H(L + W)

The sum of the areas on each of the six faces creates the rectangular prism's total surface area. This incorporates the four sidelong faces, as well as the top and base faces, which are additionally square shapes with aspects L x W. Consequently, the all out surface region is given by:

To calculate 5% of line segment AB's length, we can multiply the length of line segment AB by 0.05. This gives us:

5% of 10 = 0.05 x 10 = 0.5

So, 5% of line segment AB's length is 0.5 units. To find the length of curve DE, we need to add 0.5 units to the length of line segment AB. This gives us:

Length of curve DE = Length of line segment AB + 5% of Length of line segment AB

= 10 + 0.5

= 10.5 units
