a. What is Marisa's monthly mortgage payment to the nearest dollar?
b. How much will the house cost in total after all payments have been made, also include the down payment.
c. How much did Marisa have to spend in interest to borrow this loan?
Answer:
a. Using a mortgage calculator with the given information, Marisa's monthly mortgage payment would be $1,088 to the nearest dollar.
b. The total cost of the house, including the down payment and all payments made over the 30-year mortgage period, would be $453,020. This is calculated by adding the $55,000 down payment to the total amount borrowed ($195,000) and then adding the total interest paid over the 30 years ($203,020) to get $453,020.
c. Marisa will have spent $203,020 in interest over the 30-year mortgage period. This is calculated by subtracting the total amount of the loan ($195,000) from the total amount paid over the 30 years ($398,020), which leaves $203,020 in interest paid.

F1 = 1167.35N and F2 = 1932.65N are the contact support forces on the beam
How to calculate the contact support forces on the beam?For the torques, let the axis be at support 2 and consider torques and the counterclockwise rotation is positive.
Let m = mass of athlete and M = mass of beam.
Thus, the equilibrium of torques will be:
Mg(1.96) - mg(0.54m) - F1(3.92) = 0
Substitute the values and solve for F1:
(250 * 10 * 1.96) - (60 * 10 * 0.54) - 3.92F1 = 0
3.92F1 = 4900 - 324
3.92F1 = 4576
F1 = 1167.35N
Note: The weight of the beam is acting at the center and the distance from center to axis at support 2 is 1.96m.
Balancing forces in the vertical direction, we have:
F1 + F2 - Mg − mg = 0
1167.35 + F2 - (250 * 10) − (60 * 10) = 0
1167.35 + F2 - 2500 - 600 = 0
F2 = 1932.65N
Note: upward forces (supports) are positive and downward forces are negative.
Thus, the contact support forces on the beam are F1 = 1167.35N and F2 = 1932.65N.

A) Exponential decay; 3.5%
B) Exponential decay; 9%
C) Exponential growth; 9%
D) Exponential growth; 3.5%
The function P(t) = 3.5(0.91)^t is an exponential decay and the percentage rate of change is 9%.
option B.
What is the percentage rate of change?The function P(t) = 3.5(0.91)^t is an exponential decay function because the base, 0.91, is between 0 and 1.
To find the percentage rate of change, we need to find the value of r in the exponential function;
P(t) = P(0) (1 + r)^t or
P(t) = P(0) e^(rt)
where;
P(0) is the initial value.In this case, the initial value is 3.5, and the function is P(t) = 3.5 (0.91)^t. Comparing this to the form P(t) = P(0) e^(rt),
we see that P(0) = 3.5 and r = ln(0.91) ≈ -0.094.
Therefore, the percentage rate of change is -9.4%, which means that the value decreases by about 9.4% with each unit of time.
So the correct answer is option B: Exponential decay; 9%.

Therefore , the solution of the given problem of triangle comes out to be L = 3(√(h²) + ((w/2²))) + 3h .
What is a triangle exactly?A triangular is a polygon because it has 2 different or more additional parts. It has a straightforward rectangle form. Only the sides A, B, and C can differentiate a triangle from a parallelogram. When the sides are not exactly collinear, Euclidean geometry results in a singular surface rather than a cube. If a shape has three edges and three angles, it is said to be triangular.
Here,
Given the height and breadth of the top of the frame, we can use the Pythagorean theorem to determine the length of each side of the triangle.
Let's assume the height is h feet and the width of the top of the frame is w feet. The triangle's side lengths can then be calculated as follows:
=> s =√((h²) + ((w/2)²))
We must add up the lengths of all the pipe segments that will be used to build the frame in order to determine the total quantity of steel pipe required.
The following formula can be used to determine how much steel tubing is required:
=> L = 3s + 3h
where h is the height of the frame and s is the length of each edge of the triangle.
Using the method instead of s, we obtain:
=> L = 3(√(h²) + ((w/2²))) + 3h

The parentheses are the choices for the answer.
The choice in the blank to make the statement true will be D. between $17 and $30)
How to explain the informationRevenue = Price per book × Number of books sold = (745 - 30P) b
Since the store needs to sell at least 235 books, we have:
Revenue ≥ 235 × Price per book = 235(745 - 30P)

What is addition method?The addition method, also known as the elimination method, is a technique used to solve a system of linear equations by adding the two equations together in such a way that one of the variables is eliminated.
According to question:Multiply the first equation by -2:
-10x - 12y = -10
Add the second equation to the first:
-10x - 12y = -10

The equation of a rational function that has been translated left 2 units and shifted up 1 unit is: f(x) = (a(x - 2) + b + 1) / (c(x - 2) + d)
What is a function?A relation is a function if it has only One y-value for each x-value.
A general form of a rational function is:
f(x) = (ax + b) / (cx + d)
To translate this function left 2 units, we need to replace x with x + 2. This gives us:
f(x + 2) = (a(x + 2) + b) / (c(x + 2) + d)
To shift this function up 1 unit, we need to add 1 to the numerator. This gives us:
f(x + 2) = (a(x + 2) + b + 1) / (c(x + 2) + d)

Fill in the table, write an equation, find the LCD, and find the average rate.
The LCD we can use to simplify the equation is (2-r)(2+r) = 4 - r².
What is LCD?The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.
1. We can use the formula:
distance = rate × time
For the upstream journey:
distance = 4 miles
rate = 2 - r (since Dara is paddling against the current)
time = 4/(2-r) hours
For the downstream journey:
distance = 4 miles
rate = 2 + r (since Dara is paddling with the current)
time = 4/(2+r) hours
We can fill in the table as follows:
Distance (mi) Avg Speed (mph) Time (h)
With Current: 4 2+r (4)/(2+r)
Against Current: 4 2-r (4)/(2-r)
2. We know that the total time for the round trip is 6 hours:
4/(2-r) + 4/(2+r) = 6
3. Multiplying both sides by the LCD (2-r)(2+r), we get:
4(2+r) + 4(2-r) = 6(2-r)(2+r)
Simplifying, we get:
8 = 12 - 2r²
Rearranging, we get:
r² = 2
Taking the square root of both sides, we get:
r = ±√2
Since the current is flowing in one direction, we take the positive square root:
r = √2 ≈ 1.41 miles per hour
The LCD we can use to simplify the equation is (2-r)(2+r) = 4 - r².
4. To the nearest hundredth, the rate of the current is approximately 1.41 miles per hour, which is option B: About 1.15 miles per hour (rounded to two decimal places).

To construct a frequency distribution using class intervals, we calculate the class width as follows:
Class width = Range / Number of intervals
So, we have
Class width = (48 - 18)/5 = 6
Now we can construct the frequency distribution table:
Class Interval Frequency
18 - 23 9
24 - 29 8
30 - 35 9
36 - 41 7
42 - 47 6
48 - 53 1
The class mark for each class can be calculated as:
Class mark = (Lower limit + Upper limit) / 2
For the class boundaries, we use the following formula
Lower boundary = Lower limit - 0.5
Upper boundary = Upper limit + 0.5
For the cumulative frequency of the distribution, we need to add up the frequencies of each class and all the preceding classes.
Lastly, for the relative frequency we divide each frequency by the total frequency (40)

Dividing integers. The temperature dropped 32° F in 4 hours. Suppose the temperature dropped by an equal amount each hour. What integer describes the change?
Answer:
To find the integer that describes the change in temperature, we can divide the total temperature drop by the number of hours:
32 ÷ 4 = 8
Therefore, the temperature dropped by 8 degrees Fahrenheit each hour. The integer that describes the change is -8, since the temperature decreased.
Answer: To find the integer that describes the change in temperature, we need to divide the total change in temperature (32° F) by the number of hours over which the temperature dropped (4 hours). This will give us the amount that the temperature dropped by each hour.
So, dividing 32 by 4, we get:
32 ÷ 4 = 8

In addition to physical safeguards on all machinery, what else is considered a crucial part of providing safeguard against machine-related hazards
To have an effective safeguarding system, specific and detailed training of workers must also be included.
What constitutes the foundation of the safety system?
Any portion of the operator's body, including the hands, arms, and other body parts, must not come into touch with potentially harmful moving parts.
A strong safety system completely avoids the chance of the operator or another worker putting their bodies in close proximity to dangerous moving parts.
What are the two main sorts of protection strategies?
There are primarily two types of safeguarding: hard guards and safeguarding gadgets. Hard guards act as a physical barrier between workers and moving parts.
Safeguarding devices, however, stop unintentional access to dangers. A machine that needs two hands to operate it, for instance, ensures that neither hand may enter the danger zone.

and the remaining distance she spent 2hours 45minutes. (a) Calculate the speed for each part
of the journey. (b) Calculate the average speed for the whole journey in (i) km/h (ii) m/s to 1d.p
Answer:
2. Total Hours= 38+5 = 43
Step-by-step explanation:
2. Wage at Normal rate80 *38 = 3040
Extra Sum of Money then Normal wage 3640-3040 = 600
Overtime rate 80*1.5= 120
Overtime hours 600/120=5

A polygon has vertices whose coordinates are A(1, 4), B(4, -1), C(-1, -4), and D(-4, 1). Use the midpoint formula to determine whether or not the diagonals of polygon ABCD bisect each other. In your final answer, include all of your calculations.
Answer:
Step-by-step explanation:
midpoint of AC
[tex]x=\frac{1-1}{2} =0\\y=\frac{4-4}{2} =0\\mid ~point~of~AC=(0,0)[/tex]
midpoint of BD
[tex]x=\frac{4-4}{2} =0\\y=\frac{-1+1}{2} =0\\midpoint ~of~BD=(0,0)[/tex]

a broker invested 1,600 in a particular stock. the table shows the value og the stock and the number of weeks since the investment. wgich function best models the value of the stock v(n), in dollars, m weeks since the investment for the given period?
The exponential function that best models the value of the stock after n weeks is given as follows:
v(n) = 1600(1 + r)^n.
How to define the exponential function?The standard definition of an exponential function is given as follows:
y = a(b)^x.
In which:
a is the value of y when x = 0.b is the rate of change.The initial investment was of 1600, hence the parameter a is given as follows:
a = 1600.
The rate of change is obtained multiplying two consecutive values on the table, and will have the following format:
b = 1 + r.
In which r is the growth rate.
Missing InformationThe problem is incomplete, hence the general procedure to obtain the function is presented.

3. Colin is painting his basement floor. The dimensions are shown on the diagram below:
If one can of paint will cover 3.5 m², and each can costs $15.25, what is the total cost including 13% HST.
2.3 m
2.5 m
32m
1.8 m
The total cost of painting his basement floor is $51.70.
How to calculate total cost ?To find the total cost of the paint including HST, we first need to calculate the total area of the basement floor that needs to be painted. We can do this by multiplying the length by the width:
Area of basement floor = length x width
Area of basement floor = 2.5 m x 2.3 m + 1.8 m x 2.3 m
Area of basement floor = 5.75 m² + 4.14 m²
Area of basement floor = 9.89 m²
Now, we can calculate the number of cans of paint needed:
Number of cans = Area of basement floor / Area covered by each can
Number of cans = 9.89 m² / 3.5 m²
Number of cans = 2.8257
Number of cans = 3
The total cost of the paint without HST would be:
Total cost = Number of cans x Cost per can
Total cost = 3 x $15.25
Total cost = $45.75
To calculate the HST, we need to multiply the total cost by the HST rate (13% or 0.13):
HST = Total cost x HST rate
HST = $45.75 x 0.13
HST = $5.95 (rounded to two decimal places)
Finally, we can find the total cost including HST by adding the total cost and the HST:
Total cost including HST = Total cost + HST
Total cost including HST = $45.75 + $5.95
Total cost including HST = $51.70
Therefore, the total cost of the paint including 13% HST is $51.70.

Answer:
The distance between the student and the mirror is 7.5 feet.
Step-by-step explanation:
We can use similar triangles to solve this problem.
Let's call the distance between the student and the mirror "d". We can create a right triangle with the student's height as one leg, the distance "d" as the other leg, and the hypotenuse being the line from the student's eyes to the top of the school. Let's call the length of this line "h".
We can also create a second right triangle with the height of the school as one leg, the distance from the school to the mirror as the other leg, and the hypotenuse being the same line from the student's eyes to the top of the school.
Since these two triangles share an angle (the angle formed by the line from the student's eyes to the top of the school and the ground), they are similar triangles. This means that the ratios of their corresponding sides are equal.
We can set up the following proportion:
(student height) / d = (school height) / (distance from school to mirror)
Plugging in the given values, we get:
4.5 / d = 30 / 50
Simplifying, we get:
4.5 / d = 3 / 5
Cross-multiplying, we get:
3d = 22.5
Dividing by 3, we get:
d = 7.5
Therefore, the distance between the student and the mirror is 7.5 feet.
The distance of the student to the mirror, is 7.5 ft
What are similar triangles?Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given that, a mirror is placed outside a school the distance from the school to the mirror is 50 ft and the height of the school is 30 ft we need to find the distance of the student to the mirror,
This arrangement is creating two similar triangles, here we will use the properties of the similar triangles, to find the distance of the student to the mirror,
Therefore,
30 / 4.5 = 50 / d
d = 50 x 4.5 / 30
d = 225 / 20
d = 7.5
Hence, the distance of the student to the mirror, is 7.5 ft
