The required, Rich's monthly mortgage payment will be $1,246.91.

A mortgage payment is the amount of money that a borrower pays to a lender in order to repay a home loan.

Here,
The amount that Rich is financing with the mortgage is the difference between the total cost of the home and the down payment:

Amount financed = $244,800 - 0.15($244,800) = $208,080

To calculate the monthly mortgage payment, we can use the formula for the present value of an annuity,
[tex]PMT = (PV * r) / (1 - (1 + r)^{-n}[/tex]

First, we need to calculate the monthly interest rate. Since the annual interest rate is 5.25%, the monthly interest rate is:

r = 0.0525 / 12 = 0.004375

Next, we need to calculate the total number of payments. Since Rich is taking out a 25-year loan, he will be making 25 x 12 = 300 monthly payments.

Now we can plug these values into the formula and solve for PMT:

PMT = ($208,080 × 0.004375) / (1 - (1 + 0.004375)^(-300))

= $1,246.91

Therefore, Rich's monthly mortgage payment will be $1,246.91.

   This triangle does not have any right angles (90°), or any angles larger than a right angle, so it is an acute triangle.

The slope and y-intercept of the equation y= -4/3 x-2 are -4/3 and -2 respectively.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

In the given graph two lines are plotted.

Part A: From the graph, the two equations are intersected at (-1.5, 0) and the solution is (-1.5, 0).

Part B: Slope and y-intercept

Equations of lines from the graph are y=3/4 x+1 and y= -4/3 x-2.

For the equation y=3/4 x+1,

Step-by-step explanation:

The probability that the next component brought in for repair is a compact disc player given that it is already known to be an audio component is 0.83 or 83%.

Probability is a fundamental concept in mathematics, statistics, and various fields of science. It is used to measure the likelihood of an event occurring

In the given scenario, we are told that a certain shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio component, and let B be the event that the next component is a compact disc player. We are also given that P(A) = 0.6 and P(B) = 0.5.

The probability of B given A, denoted by P(B|A), represents the probability that event B will occur given that event A has already occurred. In other words, it tells us how likely it is that the next component brought in for repair is a compact disc player given that it is already known to be an audio component.

To calculate P(B|A), we use the formula for conditional probability:

P(B|A) = P(A and B) / P(A)

Here, P(A and B) denotes the probability that both events A and B occur. We know that event B is contained in event A, so it follows that P(A and B) = P(B). Therefore:

P(B|A) = P(B) / P(A)

Substituting the given values, we have:

P(B|A) = 0.5 / 0.6

P(B|A) = 5/6 or 0.83 (rounded to two decimal places)

Answer:

-1/2-4x/5=1/2-2x

Starting from the left side, we can simplify:

-1/2 - 4x/5 = 1/2 - 2x

Next, we can isolate x by adding 2x to both sides:

-1/2 - 4x/5 + 2x = 1/2 - 2x + 2x

-1/2 + 2x/5 = 1/2

Adding 1/2 to both sides:

0 + 2x/5 = 1

Finally, solving for x:

2x/5 = 1

Multiplying both sides by 5:

2x = 5

Dividing both sides by 2:

x = 5/2

7x² + 9x² = -6x² - 7x

Combining like terms:

16x² = -6x² - 7x

Adding 6x² to both sides:

22x² = -7x

Dividing both sides by -7:

-22x²/-7 = 7x/-7

-22x²/7 = -7x/7

-22x²/7 = -x

Multiplying both sides by -7:

22x² = x

Dividing both sides by 22:

x² = x/22

Since this equation states that x² equals x divided by 22, it has no real solutions for x.

-7x² + 6 = x² - 7x²

Combining like terms:

-8x² + 6 = 0

Adding 8x² to both sides:

-8x² + 8x² + 6 = 0 + 8x²

6 = 8x²

Dividing both sides by 8:

6/8 = 8x²/8

3/4 = x²

Taking the square root of both sides:

sqrt(3/4) = sqrt(x²)

x = +/- sqrt(3/4)

Answer:

Nick is 6

Andrea is 18

Step-by-step explanation:

Sounds like a system of equations

Letting...

a = Andrea

n = Nick

Since she's 3 times the age, the first equation will be

a = 3n

Since in 10 years, Andrea will be 12 years older than Nick, we can write

a = n + 12

Since we have two a = ,we can set them equal to each other

3n = n + 12

Subtracting n

3n - n = 12

Now combining the n's (n is the same as 1n)

2n = 12

And last but not least, we can divide by 2

n = 6... so Nick is 6 right now.

Going back to our first equation of a = 3n, if we plug 6 in

a = 6(3) = 18.

Making Andrea 18 right now

The area of sector RFS is approximately 8π square inches, and the measure of the central angle in radians is approximately 2π/3 radians.

What is the central angle?

A central angle is an angle with endpoints and located on a circle's circumference and a vertex located at the circle's center. A central angle in a circle determines an arc.

To determine the measure of the central angle in radians, we can use the formula:

radians = degrees * (π / 180)

So, for the central angle of 120°:

radians = 120 * (π / 180) = 2 * π / 3

The measure of the central angle in radians is approximately 2 * π / 3 radians.

To find the arc length of RS, we can use the formula:

arc length = (central angle / 360) * circumference

The circumference of the circle is given by 2 * π * r, where r is the radius:

circumference = 2 * π * 4 = 8 * π

So the arc length is:

arc length = (120 / 360) * (8 * π) = 4 * π / 3

The arc length of RS is approximately 4 * π / 3 inches.

To find the area of sector RFS, we can use the formula:

area = (central angle / 360) * π * r²

So the area of sector RFS is:

area = (120 / 360) * π * (4)² = 8 * π

Therefore, The area of sector RFS is approximately 8π square inches, and the measure of the central angle in radians is approximately 2π/3 radians.

The number of chips sold is 10

The number of candy bars sold is 23

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

The price of each candy bar = $1.50.

The price of each bag of chips = $1.25.

Number of chips = x

Number of candy bar = x + 13

Yesterday Melanie made $33.25.

So,

x + x + 13 = 33.25

Solve for x.

x + x + 13 = 33.25

2x + 13 = 33.25

2x = 33.25 - 13

2x = 20.25

x = 10.125

x = 10

Now,

Number of chips = 10

Number of candy bar = 10 + 13 = 23

Tammy received 19 phone calls on the first evening, 13 phone calls on the second evening, and 76 phone calls on the third evening.

Let's use algebra to solve the problem.

Let x be the number of phone calls Tammy received on the first evening.

According to the problem, she received 6 fewer calls on the second evening than on the first evening. This means that the number of phone calls she received on the second evening is x - 6.

The problem also states that she received 4 times as many calls on the third evening as she did on the first evening. This means that the number of phone calls she received on the third evening is 4x.

We know that Tammy received a total of 108 phone calls over the three evenings. We can use this information to set up an equation:

x + (x - 6) + 4x = 108

Simplifying the equation:

6x - 6 = 108

Adding 6 to both sides:

6x = 114

Dividing both sides by 6:

x = 19

The given functions f(x) = 3x + 6 and g(x) = (x+5)/3 are not inverses of each other, as their compositions of functions are not equal.

When we want to check if two functions are inverses of each other, we need to verify if composing the functions in both orders results in the input variable. In other words, we need to check if (f ∘ g)(x) = x and (g ∘ f)(x) = x, where f and g are the two functions.

For this problem, we have two functions:

f(x) = 3x + 6

g(x) = (x + 5)/3

Let's start by computing (f ∘ g)(x):

(f ∘ g)(x) = f(g(x)) = f((x + 5)/3) = 3((x + 5)/3) + 6

We can simplify this by canceling the 3's:

(f ∘ g)(x) = x + 5 + 6 = x + 11

Now let's compute (g ∘ f)(x):

(g ∘ f)(x) = g(f(x)) = g(3x + 6) = ((3x + 6) + 5)/3

Again, we can simplify this by canceling the 3's:

(g ∘ f)(x) = (3x + 11)/3

We can see that neither (f ∘ g)(x) nor (g ∘ f)(x) is equal to x, so we can conclude that the functions f(x) = 3x + 6 and g(x) = (x + 5)/3 are not inverses of each other.

Interior angle of a regular hexagon = 120°

The 10 cm segment bisects the top vertex angle of the regular hexagon, which together with the 5·√3 cm side and trigonometric ratios, indicates that we get;

sin(60) = s/(5·√3) = (√3)/2

Where;

s = The side length of the regular hexagon

(5·√3)/s = (√3)/2

s = (5·√3)/((√3)/2) = 10

The side length of the regular hexagon, s = 10

The area of the regular hexagon, A = ((3·√3)/2) × s² = (1/2)×6 ×s ×a
