A certain college has 11,989 students. Assume that 6120 are unemployed sophomores, juniors, or seniors and that 4104 are employed sophomores, juniors, or seniors. There are 745 employed freshmen. Use
for freshmen and
for employed students, and make a Venn diagram marking the number of students in each region of the diagram. How many freshmen are there?
Step-by-step explanation:
Since 4104 students are employed sophomores, juniors, or seniors, the total number of unemployed students is 11,989 - 4104 = 7885.
And since 745 students are employed freshman, the number of unemployed freshman is 7885 - 745 = 7140.
So, the total number of freshman is 745 + 7140 = 7885.
The Venn diagram would look like this:
[ Freshmen ] [ Sophomores, Juniors, Seniors ]
[ 7885 ] __________ [ 4104 ]
| 745 |
__________
[ 7140 ]
So, there are 7885 freshman.
Find the exact values of the six trigonometric functions of θ.
Answer & Explanation:
sin Θ = opp/hyp
cos Θ = adj/hyp
tan Θ = opp/adj
csc Θ = hyp/opp
sec Θ = hyp/adj
cot Θ = adj/opp
1.
sin Θ = opp/hyp = (8√2)/18 = (4√2)/9
cos Θ = adj/hyp = 14/18 = 7/9
tan Θ = opp/adj = (8√2)/14 = (4√2)/7
csc Θ = hyp/opp = 18/(8√2) = (9√2)/(4√2√2) = (9√2)/8
sec Θ = hyp/adj = 18/14 = 9/7
cot Θ = adj/opp = 14/(8√2) = (7√2)/(4√2√2) = (7√2)/8

Use the appropriate amortization formula to find (a) the
monthly (n = 12) payment on a loan with the given conditions
and (b) the total interest that will be paid during the term of the
loan.
$6,200 is amortized over 8 years at an interest rate of 7.5%.
Answer:
Step-by-step explanation:
The monthly payment on a loan and the total interest that will be paid during the term of the loan can be found using an amortization formula.
Here are the steps to find the monthly payment and total interest for the given loan conditions:
Convert the interest rate to a decimal: 7.5% = 0.075
Divide the interest rate by the number of periods (months) per year: 0.075 / 12 = 0.00625
Find the number of payment periods: 8 years * 12 months/year = 96
Calculate the monthly payment using the amortization formula:
Payment = Loan Amount * (Interest Rate / (1 - (1 + Interest Rate)^(-Number of Payments)))
Payment = $6,200 * (0.00625 / (1 - (1 + 0.00625)^(-96)))
Payment = $79.88
So, the monthly payment on the loan is $79.88.
Calculate the total interest paid over the term of the loan:
Total Interest = (Monthly Payment * Number of Payments) - Loan Amount
Total Interest = ($79.88 * 96) - $6,200
Total Interest = $7,538.88
So, the total interest that will be paid during the term of the loan is $7,538.88.

a grandfather is 9 times as old as his granddaughter. In 8 years, the grandfather will be 5 times as old as his granddaughter. How old is each of them now?
Answer:
The grandfather is 72 years old and the granddaughter is 8 years old now.
Step-by-step explanation:
To calculate this, first calculate the grandfather's age in 8 years:
72 + 8 = 80.
Then, use the given information to calculate the granddaughter's age in 8 years: 8 + 8 = 16.
Finally, use the given information to calculate the grandfather's age now: 5 x 16 = 80, so 80/5 = 16, and 16 x 9 = 72.

An angle measures 61.2° more than the measure of its complementary angle. What is the measure of each angle?
Answer: 75.6, 14.4
Step-by-step explanation:
Note 2 angles are complementary if they adds up to 90 degrees. Lets set x to be the first angle.
x - (x - 61.2) = 90
Then we can know:
2x = 90 + 61.2;
2x = 151.2;
x = 75.6
Now we know the first angle is 75.6, we know the second angle is 75.6 - 61.2 = 14.4. Hope you find this helpful!
A rectangular field is six times as long as it is wide. If the perimeter of the field is
770 feet, what are the dimensions of the field?
A) Write an equation you can
to answer the given question lot an be the width
Answer:
6W + W = 770
==> 7W = 770
W = 110 and L = 660 in case you are looking for the solution
Step-by-step explanation:
Let L -= length and W the width of the rectangular field
six times as long as it is wide translates to:
L = 6W
Perimeter of field = 2(L + W)
Given perimeter = 770 feet
2(L + W) = 770
L + W = 770/2 = 385
Since L = 6W, substitute for L in the above equation:
6W + W = 770
7W = 770
W = 770/7 = 110 feet
L = 6W = 6(110) = 660 feet
the width = 55 feet and the length = 330 feet
so basically we take the width as x and the length as 6x then since the perimeter of a rectangle = 2*width + 2*length we will form the equation 6x + 6x + x + x = 770
then we'll solve this equation
14x = 770
x = 55
then multiply x by 6 to get the length which is 330
in the graph is there any meaning to the width of the bars, the spacing between the bars, or the ordering of the bars? explain and include how this is different than a bar graph.
In a histogram, the width of the bars represents the range of values that fall into each specific category or bin. The spacing between the bars has no meaning in terms of the data being represented.
The ordering of the bars is based on the range of values within each bin, with the bars typically ordered from left to right in ascending order of value.
This is different from a bar graph, where the width and spacing of the bars can have meaning in terms of the comparison of the values being represented. For example, if the width of the bars in a bar graph represents the value of a data point, then a wider bar would indicate a higher value.
The spacing between the bars in a bar graph can also be used to show the relative difference between values. In a bar graph, the ordering of the bars may or may not have meaning, depending on the specific context and the purpose of the graph.

The ratio of Mr Lim's age to his son's age is 5:2. Four years ago, the ratio of their ages was 3:1. How old will Mr Lim be in 6 years time?
The old will Mr Lim be in 6 years time is 46 years old.
To make solving this problem easier, we need to consider the ages of Mr Lim and his son. For example by multiplying the number x.
Let:
Mr Lim's age = a
His son's age = b
So that,
The ratio of ages in the current year:
Mr Lim's age to his son's age = 5x : 2x
a : b = 5x : 2x
The ratio of ages in the four years ago:
Mr Lim's age to his son's age = 3x : x
(a - 4) : (b - 4) = 3x : x
[tex]\frac{a-4}{b -4} =\frac{3x}{x}[/tex]
[tex]\frac{5x-4}{2x -4} =\frac{3x}{x}[/tex]
[tex]\frac{5x-4}{2x -4} =\frac{3}{1}[/tex]
5x - 4 = 6x - 12
5x - 6x = -12 + 4
-x = -8
x = 8
So that we know the age of Pak Lim's and the age of his son's this year.
Mr Lim's age = 5x
= 5 × 8
= 40 years old
His son's age = 2x
= 2 × 8
= 16 years old
After that, we find Mr Lim's age 6 years from now by adding 6 years to this year's age.
Mr Lim's age be in 6 years time = 40 + 6
= 46 years old
So, the old will Mr Lim be in 6 years time is 46 years old.

If csc = 29/21, then the reciprocal of this is equal to the sine of the angle. So,
sin = 21/29.
Since cosine is less than 0, then the angle must be in the second or third quadrant, which means that the sine of the angle must be positive. So,
sin = 21/29, and cos = -√(1 - sin^2) = -√(1 - (21/29)^2)
Next, we can find the tangent by taking the ratio of sine to cosine:
tan = sin / cos = 21/29 / -√(1 - (21/29)^2) = -21/√(841 - 441)
Finally, we can find the cotangent by taking the reciprocal of the tangent:
cot = 1 / tan = -√(841 - 441) / 21
So, the remaining trigonometric functions are:
sin = 21/29
cos = -√(1 - (21/29)^2)
tan = -21/√(841 - 441)
cot = -√(841 - 441) / 21

(please don't answer unless you can really answer it)
Answer:
Step-by-step explanation:
The factored form of a polynomial function with roots r1 and r2 can be found by multiplying two linear factors (x - r1) and (x - r2).
Here are the steps to find the factored form of the polynomial function with roots 3i and 2:
Write the first linear factor: (x - 3i)
Write the second linear factor: (x - 2)
Multiply the two linear factors: (x - 3i)(x - 2)
Expand the product to find the polynomial function:
x^2 - (3i + 2)x + (3i * 2) = x^2 - 2x - 6i
And there you have it, the factored form of the polynomial function with roots 3i and 2 is x^2 - 2x - 6i.

Can someone help in number 9?
Answer: 200 dollars more
Step-by-step explanation: I did 30% of 500 which is 150 that Noel has.
70% of 500 which is 350. 350-150 is 200
Frank has saved 200$ more than Noel
Answer: 200 dollars
The first step that we should do is divide 500 into 10 separate parts. Each part is 10 percent of the price. 500 divided by 10 is 50.
This means that Frank saved 50 x 7 and Noel saved 50 x 3.
50 x 7 is 350 and 50 x 3 is 150.
Frank saved 350 , while Noel saved 150.To check if we are correct we can add 350 and 150, which is 500 that brings us back to our original answer. Next we must subtract Franks total from Noel to figure out the difference.
350-150 is 200.
This means that Frank saved 200 more dollars than Noel.
I hope this helped & Good Luck <3 !!!
