You take out $50,000 for loans during your college career. You must pay it back with 7% APR for 20 years, making monthly payments. Calculate the minimum monthly payment needed to do this.
Answer:
The monthly payment for the loan amount for 20 years is $806.167
Step-by-step explanation:
The principal loan amount= $ 50,000
The rate of interest = 7 %
the time period of loan = 20 years = 20 × 12 = 240 months
let the amount after 20 years = $ A
From Compounded method
Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm Time}[/tex]
or, A = 50,000 × [tex](1+\dfrac{\textrm 7}{100})^{\textrm 20}[/tex]
or, A = 50,000 × [tex](1.07)^{20}[/tex]
Or, A = 50,000 × 3.8696
∴ Amount = $ 193,480
So, The amount after 20 years = $ 193,480
The monthly payment amount = $ [tex]\frac{193480}{240}[/tex] = $ 806.167
Hence The monthly payment for the loan amount for 20 years is $806.167 Answer

Ryaan goes skydiving and falls at a constant rate toward the ground. The equation y = -32x + 14,000 represents the situation where y is the height of Ryaan in feet above the ground and x is the seconds since she jumped.
Which statement describes the situation?
a. From a starting position of 14,000 feet above the ground, she is ascending at 32 feet per second.
b. From a starting position of 32 feet above the ground, she is ascending at 14,000 feet per second.
c. From a starting position of 14,000 feet above the ground, she is descending at 32 feet per second.
d. From a starting position of 32 feet above the ground, she is descending at 14,000 feet per second.
MUTIPLE CHOICE ANSWER!!!1
Answer:
C, because
-32 x seconds since she jumped + 14000
because 14000 would be 14000 units above 0, and -32 represents the seconds she had jumped, which would basically be -32+14000, which is the same as saying 14000 - 32.
Write an equation In slope intercept form for the line that is parallel to the given line and that passes through the given point
5x - 2y=10 (3 -5)
The equation of the parallel line in slope-intercept form is;
y = [tex]\frac{5}{2}[/tex] x - [tex]\frac{25}{2}[/tex]
Step-by-step explanation:
Let us revise some facts about parallel lines
The equations of two parallel lines have:
Same slopesDifferent y-interceptThe slope-intercept form of the equation of a line is y = m x + b, where m is the slope of the line and b is the y-intercept
The given line has equation 5x - 2y = 10
Put it in the form of y = m x + b to find its slope
∵ 5x - 2y = 10
- Subtract 5x from both sides
∴ -2y = 10 - 5x
- Divide to sides by -2
∴ y = -5 + [tex]\frac{5}{2}[/tex] x
∴ y = [tex]\frac{5}{2}[/tex] x - 5
- The value of m is the coefficient of x
∴ m = [tex]\frac{5}{2}[/tex]
∴ The slope of the given line is [tex]\frac{5}{2}[/tex]
∵ Parallel lines have same slopes
∴ The slope of the parallel line is m = [tex]\frac{5}{2}[/tex]
- Substitute the value of m in the form of the equation
∴ The equation of the parallel line is y = [tex]\frac{5}{2}[/tex] x + b
To find b substitute x and y in the equation by the coordinates of any point lies on the line
∵ The parallel line passes through point (3 , -5)
- Substitute x and y by the coordinates of the point (3 , -5)
∵ x = 3 and y = -5
∴ -5 = [tex]\frac{5}{2}[/tex] (3) + b
∴ -5 = [tex]\frac{15}{2}[/tex] + b
- Subtract [tex]\frac{15}{2}[/tex] from both sides
∴ b = [tex]\frac{-25}{2}[/tex]
∴ The equation of the parallel line is y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{-25}{2}[/tex]
∴ The equation of the parallel line is y = [tex]\frac{5}{2}[/tex] x - [tex]\frac{25}{2}[/tex]
The equation of the parallel line in slope-intercept form is;
y = [tex]\frac{5}{2}[/tex] x - [tex]\frac{25}{2}[/tex]

Describe the pattern 0.13, 0.65, 3.25, 16.25
Let n be the current term and n+1 be the next term
Then the pattern is: n+1 = n * 5
Step-by-step explanation:
Given series is:
0.13, 0.65, 3.25, 16.25
We can find the ratio between consecutive numbers to find the pattern
So,
[tex]Ratio = \frac{0.65}{0.13}\\=5[/tex]
We can see that multiplying the previous term with 5 gives us the next term
0.13 * 5 = 0.65
0.65 * 5 = 3.25
3.25 * 5 = 16.25
Let n be the current term and n+1 be the next term
Then the pattern is: n+1 = n * 5

A radar beacon 40 feet above the ground picks up an airplane approaching at an angle of elevation
of 43 degrees and a distance of 6,390 feet. How high above the ground is the plane in whole feet?
5,998.7714 ft
Step-by-step explanation:
Well find x in the illustration;
First To find the opposite side of the right-angled triangle we'll using tangent of the given angle
Tangent Ф = Length of the opposite side / Length of the adjacent side
Tan 43 = h / 6390
h = Tan (43) * 6390
h = 5,958.7714 ft
Then we'll add the height of the beacon which is 40 ft above ground;
x = 5,958.7714 ft + 40 ft

Darcie wants to crochet a minimum of 3 blankets to donate to a homeless shelter. Darcie crochets at a rate of
of a blanket per day. She has 60 days until when she wants to donate the blankets, but she also wants to
skip crocheting some days so she can volunteer in other ways.
Write an inequality to determine the number of days, s, Darcie can skip crocheting and still meet her goal.
How many days can Darcie skip to still meet her goal?
Answer:
I believe it's 15 days
Answer:
The maximum number of days that she can skip crocheting is s = 57
Step-by-step explanation:
Darcie wants to crochet a minimum of 3 blankets.
She can crochet at a rate of a blanket per day, so she makes 1 blanket in one day.
She has a total of 60 days to work.
If X is the number of days that she works, we can write it as:
X ≥ 3
This means that she works at least 3 days, so she makes at least 3 blankets.
X < 60
This means that she not can work 60 days or more, in this way she has at least one day to do another volunteer job.
then
3 ≤ X < 60
then we have:
1 ≤ s ≤ 60 - 3 = 57
where s is the days that she can skip, where the less or equal sign is used because we have a bigger or equal sign previously.
The maximum number of days that she can skip
The maximum number of days that she can skip crocheting is when the right equality is true, so s = 57.

On five different tests Jake got: 75, 80, 81, 96, and 100. Would the mean of these numbers be greater than the median of these numbers?
Answer:
Yes the mean is greater than the median
Step-by-step explanation:
To find the mean of numbers, you add all of them and divide them by how many there are in total.
75+80+81+96+100= 432
There are five numbers so divide the total by 5.
432÷5= 86.4
That is your mean.
The median is the one in the middle. There are five numbers, so the one in the middle is 81.
The mean is 86.4 and the median is 81.
Answer:
the mean is greater
Step-by-step explanation:
well mean is average so lets do that first
to find the mean, you add all of the percentages up and divide it by the amount of percentage
75 + 80 + 81 + 96 + 100 = 155 + 177 + 100 = 432
and now you divide 432 by 5 to get 86.4
so the mean is 86.4
and the median is the middle:
75 80 81 96 100
↑
81 is the median since its in the middle
86.4 > 81
so the mean is greater than the median

The coordinates of the vertices of triangle 1 are A(6,6), B(12,9), C(9,6).
The coordinates of the vertices of triangle 2 are A′(2,2), B′(4,3), C′(3,2).
What transformation was performed on triangle 1 to create triangle 2?
Answer:
A
Step-by-step explanation:
The transformation performed on triangle 1 to create triangle 2 is a translation by the vector (-4, -4), which means each point was moved 4 units to the left and 4 units down.
Explanation:The transformation used can be determined by observing the differences between corresponding coordinates in the two triangles. If we subtract the coordinates of A′(2,2) from A(6,6), for instance, we get a change of -4 in the x-direction and -4 in the y-direction. Similarly, subtracting B′(4,3) from B(12,9) and C′(3,2) from C(9,6) results in changes of -8 and -6 in the x-direction and -6 and -4 in the y-direction, respectively.
This means that every point on triangle 1 was moved 4 units to the left and 4 units down to create triangle 2. Thus, the transformation that took place is called a translation by the vector (-4, -4).

You are comparing apples to oranges in a fruit bowl. Is the ratio 2:3 the same as the ratio 3:2?
Answer:
No, the two ratios are not the same.
Step-by-step explanation:
When we are saying "apples to oranges", mathematically it means:
[tex]\frac{Apples}{Oranges}[/tex],
Which could be 2:3 or 3:2, which in fractional from are written as [tex]\frac{2}{3}[/tex] and [tex]\frac{3}{2}[/tex] respectively.
We see that
[tex]\frac{2}{3} \neq \frac{3}{20}.[/tex]
In words the ratio 2:3 says "for every two apples there are three oranges", and 3:2 says "for every three apples there are two oranges". Again we see that the two sentences are not saying the same thing, therefore the ratio 2:3 is not same as 3:2.
Final answer:
The ratio 2:3 is not the same as 3:2 because they represent different relationships between the quantities of apples and oranges in a comparative scenario or barter trade. These ratios suggest different terms of trade and would result in different exchange outcomes.
Explanation:
The question is whether the ratio 2:3 is the same as 3:2 when comparing apples to oranges. To understand this, we must recognize that a ratio represents a relationship between two quantities, expressing how many times one value contains the other or is contained within it. In the context of a fruit bowl, a ratio of 2:3 would mean for every 2 apples, there are 3 oranges, while the ratio 3:2 means for every 3 apples, there are 2 oranges. Therefore, these two ratios are not the same as they represent different relationships between the quantities of apples and oranges.
Considering ratio comparisons like in barter trading, the terms of trade are critical. If 2 bushels of apples can be traded for 3 bushels of oranges, that is a 2:3 apple-to-orange trade ratio. On the other hand, if we reverse the ratio to 3:2, it would mean something quite different for trade or value comparisons. Specifically, you'd need 3 bushels of apples to get 2 bushels of oranges.
It's essential to compare apples to apples; comparative statistics are only useful when the comparison is logical and applicable. The ratios 2:3 and 3:2 convey different terms and thus would yield different outcomes in any exchange or comparative scenario.

Step-by-step explanation:
Given expression as :
[tex](\dfrac{x^{6}\times x^{10}}{x^{-3}})^{2}[/tex]
Now, From the common radix method
∵ In multiplication of radix , if the radix is same , then power is added
I.e [tex]x^{6}\times x^{10[/tex] = [tex]x^{6+10}[/tex]
Or , [tex]x^{6}\times x^{10[/tex] = [tex]x^{16}[/tex]
Now, The expression can be written as
[tex](\frac{x^{16}}{x^{-3}})^{2}[/tex]
And In Division of radix , if the radix is same , then power is subtracted
So, [tex]\frac{x^{16}}{x^{-3}}[/tex]
Or, [tex]x^{16 - (-)3}[/tex]
Or, [tex]x^{16 + 3}[/tex]
or, [tex]x^{19}[/tex]
∴ The expression is now
[tex](x^{19})[/tex]²
Now, again this is written as
[tex]x^{19}[/tex] × [tex]x^{19}[/tex]
I.e here again the radix is same and in multiple for, so, power is added
∴ [tex]x^{19}[/tex] × [tex]x^{19}[/tex] = [tex]x^{19+19}[/tex]
I.e [tex]x^{19}[/tex] × [tex]x^{19}[/tex] = [tex]x^{38}[/tex]
Hence The solution for the given expression is [tex]x^{38}[/tex] , i.e option C . Answer
