Answer:
We can use the double angle identity for sine to find sin2θ:
sin2θ = 2sinθcosθ
Since cosθ = √10/8 and 3π/2 < θ < 2π, we know that θ is in the fourth quadrant, where sine is negative. We can use the Pythagorean identity to find the value of sinθ:
sin²θ + cos²θ = 1
sin²θ = 1 - cos²θ
sinθ = -√(1 - cos²θ)
Substituting the value of cosθ, we get:
sinθ = -√(1 - (√10/8)²) = -√(1 - 5/16) = -√(11/16) = -√11/4
Now we can plug in the values of sinθ and cosθ into the double angle identity for sine:
sin2θ = 2sinθcosθ = 2(-√11/4)(√10/8) = -√110/16 = -√(11/4)(10/16) = -√(55/8)
Therefore, sin2θ = -√55/8 when cosθ = √10/8 and 3π/2 < θ < 2π.

The answer of the given question based on finding the area of the triangle the answer is the area of the given triangle is 15 square units.
What is Triangle?A triangle is three-sided polygon, which means it is closed shape with three straight sides and three angles. Triangles are some of most basic shapes in geometry and can be found in the many different contexts, from simple constructions to complex mathematical models.
To find the area of the triangle, we can use the formula A = (1/2)bh, where A is the area, b is the base, and h is the height.
Looking at the given triangle, we can see that the base is the line segment from (0, 0) to (6, 0), which has a length of 6 units.
The third vertex of the triangle appears to be at the point (2, 5), so we need to find the distance from this point to the base.
The equation of the base is y = 0, so the distance from the point (2, 5) to the base is:
d = |0(2) - 1(5) + 0| / sqrt(0² + 1²) = 5 / 1 = 5 units
Therefore, the height of the triangle is 5 units.
Now we can use the formula A = (1/2)bh to find the area:
A = (1/2)(6)(5) = 15 square units
Therefore, the area of the given triangle is 15 square units.

There are 44 students going to see a movie. Each row
holds 8 people. How many rows do they fill up?
Make a drawing for this problem that would explain
your answer to someone else.
Answer:
To solve this problem, we need to divide the total number of students by the number of people that can sit in each row.
44 students ÷ 8 people per row = 5.5 rows
Since we cannot have half a row, we round up to the nearest whole number. Therefore, they will fill up 6 rows in the movie theater.
Here's a simple drawing that explains the solution:
Row 1: 8 students
Row 2: 8 students
Row 3: 8 students
Row 4: 8 students
Row 5: 8 students
Row 6: 4 students
The first five rows are full with 8 students each, and the sixth row has the remaining 4 students. Therefore, a total of 6 rows will be filled with students.
Jenny has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans. She took out a car loan for $40,000 payable for 6 years at an interest rate of 15%. If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 5%. Approximately how much more in interest over the life of the loan does Jenny have to pay?
Hint: 1st, use minimum monthly payment formula: to calculate the monthly payment at 15%, where PV = 40,000, i = 0.15/12, and n = 72.
2nd, once you find P multiply it by 72 months to find how much you paid for the lifetime of the loan.
3rd, finally, subtract 40,000 from it to find out the interest you paid at 15%.
Now repeat steps 1-3 above for the loan at 5% (how much you could have had it for if Jenny did not have bankruptcy). Only I is different, which is 0.05/12.
Now compare the interest at 15% for the first loan and the interest at 5% for the second loan. What is the difference?
a.
$6,382.21

The difference in interest paid between the two loans is the answer is option (c) $14,515.43.
What is the interest?
Calculate simple interest, and multiply the principal amount by the interest rate and the time. The formula written out is "Simple Interest = Principal x Interest Rate x Time." This equation is the simplest way of calculating interest.
First, we need to calculate the monthly payment for the loan at 15%:
PV = $40,000
i = 0.15/12 = 0.0125
n = 6 years * 12 months/year = 72 months
Using the formula for minimum monthly payment for an amortized loan, we get:
[tex]P = i * PV / (1 - (1 + i)^{(-n)})[/tex]
= 0.0125 * $40,000 / (1 - (1 + 0.0125)⁻⁷²) = $797.95
So Jenny's monthly payment is $797.95 for the 6-year term of the loan.
The total amount paid over the life of the loan at 15% is:
Total paid = P * n = $797.95 * 72 = $57,471.44
The interest paid at 15% is:
Interest paid = Total paid - PV = $57,471.44 - $40,000 = $17,471.44
Now, let's repeat the same calculation for the loan at 5%:
PV = $40,000
i = 0.05/12 = 0.0041667
n = 6 years * 12 months/year = 72 months
Using the same formula, we get:
P = i * PV / (1 - (1 + i)^(-n)) = 0.0041667 * $40,000 / (1 - (1 + 0.0041667)^(-72)) = $630.48
So Jenny's monthly payment would have been $630.48 for the 6-year term of the loan if she did not have a bankruptcy.
The total amount paid over the life of the loan at 5% is:
Total paid = P * n = $630.48 * 72 = $45,434.56
The interest paid at 5% is:
Interest paid = Total paid - PV = $45,434.56 - $40,000 = $5,434.56
The difference in interest paid between the two loans is:
$17,471.44 - $5,434.56 = $12,036.88
Therefore, The difference in interest paid between the two loans is the answer is option (c) $14,515.43.

Scott Salman, a travel agent, is paid on variable commission, is married, and claims four withholding allowances. He receives 3% of the first $20,000 in sales, 4% of the next $10,000 in sales, and 6% of all sales over $30,000. This week he has sales of $45,550 and the following deductions: FICA, Medicare, federal withholding, state disability insurance, state withholding, a retirement contribution of $45, a savings bond of $50, and charitable contributions of $20. Find his net pay after subtracting all of his deductions.
Scott Salman's net pay after subtracting all his deductions is $1,185.97.
How to calculate interest ?
To calculate Scott Salman's net pay after all deductions, we need to first determine his gross pay based on his variable commission.
Sales up to $20,000 will earn him a commission of 3%, which is $600. Sales between $20,000 and $30,000 will earn him a commission of 4%, which is $400. For sales over $30,000, he will receive a commission of 6%. In this case, the sales over $30,000 are $45,550 - $30,000 = $15,550, so his commission on this amount is $933.
Adding up all three commissions, Scott's gross pay is $1,933 ($600 + $400 + $933).
Next, we need to calculate his total deductions. FICA and Medicare deductions are based on a percentage of gross pay, which is 7.65%. For Scott, this comes out to be $147.70 ($1,933 x 7.65%).
Federal and state withholdings are calculated based on his tax bracket and filing status. Assuming he is filing jointly with his spouse, we can estimate his federal withholding to be $345 and state withholding to be $120.
State disability insurance varies by state and cannot be estimated without knowing where Scott lives. Assuming a standard rate of 1%, this comes out to be $19.33 ($1,933 x 1%).
Adding up all these deductions, we get a total of $632.03 ($147.70 + $345 + $120 + $19.33).
In addition, Scott has also made contributions towards his retirement plan, savings bond, and charitable donations. His retirement contribution is $45, his savings bond is $50, and his charitable contributions are $20. Adding these up, his total additional deductions come to $115.
Subtracting his total deductions from his gross pay, we get Scott's net pay:
$1,933 - $632.03 - $115 = $1,185.97.
Therefore, Scott Salman's net pay after subtracting all his deductions is $1,185.97.

Find the area of the triangle with vertices A(1, 1, 2), B(2, 3, 5) and C(1,5,5).
To find the area of a triangle in three-dimensional space, we can use the cross product of two vectors that lie in the plane of the triangle. We can use the vectors formed by subtracting the coordinates of one vertex from the other two vertices.
Let's take A as our reference vertex. Then the vectors AB and AC can be calculated as follows:
AB = B - A = (2, 3, 5) - (1, 1, 2) = (1, 2, 3)
AC = C - A = (1, 5, 5) - (1, 1, 2) = (0, 4, 3)
To find the area of the triangle, we need to take the magnitude of the cross product of AB and AC and divide by 2:
Area = |AB x AC| / 2
where x denotes the cross product. The cross product of AB and AC can be calculated as follows:
AB x AC = (23 - 54, 50 - 13, 14 - 20) = (-7, -3, 4)
Taking the magnitude of this vector gives:
|AB x AC| = sqrt((-7)^2 + (-3)^2 + 4^2) = sqrt(74)
Therefore, the area of the triangle with vertices A(1, 1, 2), B(2, 3, 5) and C(1, 5, 5) is:
Area = |AB x AC| / 2 = sqrt(74) / 2
So, the area of the triangle is (1/2) sqrt(74) square units.

After how many seasons will the population reach 1690 fish? Write an equation for a second fish population that grows by 60 new fish each season with an initial population of 1100 fish. After how many seasons will they have the same population?
Graph your equations in the coordinate plane.
Help please
The equation to model the fish population y in a fishery with a linear growth rate of 40 new fish each season and an initial population of 1250 fish can be written as:
y = 40x + 1250What is the equation about?The equation to model the fish population y in a fishery with a linear growth rate of 40 new fish each season and an initial population of 1250 fish can be written as:
y = 40x + 1250
where x is the number of seasons.
To find out how many seasons it will take for the population to reach 1690 fish, we can substitute y = 1690 into the equation and solve for x:
1690 = 40x + 1250
440 = 40x
x = 11
So it will take 11 seasons for the population to reach 1690 fish.
For the second fish population that grows by 60 new fish each season with an initial population of 1100 fish, the equation to model the population can be written as:
y = 60x + 1100
To find out after how many seasons they will have the same population, we can set the two equations equal to each other and solve for x:
40x + 1250 = 60x + 1100
20x = 150
x = 7.5
So it will take 7.5 seasons for the two populations to have the same population.
To graph the equations, we can plot points on the coordinate plane using values of x and y. For the first equation, we can plot the points (0, 1250) and (11, 1690). For the second equation, we can plot the points (0, 1100) and (7.5, 1500). Then we can connect the points with a straight line for each equation. The resulting graph will show how the populations of the two fish populations change over time.(Note: In the question, A season is not defined and as such, we assume it to be one year for simplicity.)

find the total amount in Mr.hunter account, if he invests $900 for 2 years at 6% interest rate
Answer:
To find the total amount in Mr. Hunter's account, we need to use the formula:
A = P(1 + r/n)^(nt)
where:
A = the total amount
P = the principal amount (the initial investment)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
In this case, P = $900, r = 0.06, n = 1 (compounded annually), and t = 2.
So, plugging in these values, we get:
A = 900(1 + 0.06/1)^(1*2)
A = 900(1.06)^2
A = 900(1.1236)
A = $1,011.24
Therefore, the total amount in Mr. Hunter's account after 2 years is $1,011.24.

Answer: It's not clear what measures 3.8 and 9.2 represent. However, if they represent angles in degrees, then the range of these measures would be:
- If there are no restrictions on the angles, the range would be [0°, 360°), meaning any angle between 0 degrees and 360 degrees (excluding 360 itself).
- If the angles are restricted to be acute angles (less than 90 degrees), then the range would be (0°, 90°), meaning any angle between 0 degrees and 90 degrees (excluding 0 and 90 themselves).
- If the angles are restricted to be obtuse angles (between 90 and 180 degrees), then the range would be (90°, 180°), meaning any angle between 90 degrees and 180 degrees (excluding 90 and 180 themselves).
- If the angles are restricted to be right angles (exactly 90 degrees), then the range would be {90°}, meaning only the angle of 90 degrees.

You have found three investment choices for a one - year deposit:
10% APR compounded monthly,
10% APR compounded annually, and
9% APR compounded daily.
Compute the EAR for each investment choice. (Assume there are 365 days in the year)
Part A: 10% APR compounded monthly: EAR = 10.47%.
Part b: 10% APR compounded annually: EAR = 10%.
Part c: 9% APR compounded daily: EAR = 9.42%
Explain about the Effective Annual Interest Rate?The anticipated rate of return with compound interest is known as the effective annual interest rate. The yearly percentage rate of an investment will be less than its effective annual interest rate because of compounding.Part A: 10% APR compounded monthly,
Effective annual interest rate (EAR):
EAR = [tex](1 + \frac{I}{n} )^{n }[/tex] - 1
I is the annual percentage rate/nominal interest rate
n is the number of compounding periods (in a year)
For monthly compounding.
EAR = [tex](1 + \frac{0.10}{12} )^{12}[/tex] - 1
EAR = 10.47%
Part b: 10% APR compounded annually,
For annual compounding.
The effective yearly interest rate will be the same as the nominal interest rate if the interest rate gets compounded annually.
EAR = Nominal interest rate
EAR = 10%
Part c: 9% APR compounded daily.
EAR = [tex](1 + \frac{0.09}{365} )^{365}[/tex] - 1
EAR = 9.42%

Prove the divisiblity of each of the following numbers 7^6+7^5-7^4 by 11
The Expression came in two parts, we started by solving the first part and getting a whole number and the second part was used to divide the first part.
The answer is 12005
Given Data
we have the expression
7^6+7^5−7^4 by 11
The dividend = 7^6+7^5−7^4
The divisor = 11
Let us express the dividend as a whole number
7^6+7^5−7^4 = 117649 + 16807 - 2401
7^6+7^5−7^4 = 132055
Hence the expression 7^6+7^5−7^4 by 11
= 132055/11
= 12005 ans
Giving the function find the answer

Your answer should be -2x
Step-by-step explanation:
I am not sure if your teacher taught you the short cut way of doing derivatives yet.
That equation is just a long way to do derivatives. The picture below shows the shortcut way to do dervatives.
So basically you plug in x+h into the equation given to you.
[tex]\frac{g(x+h)-g(x)}{h} \\\\\frac{(6-(x+h)^2)-g(x)}{h} \\\\\frac{(6-(x^2+2xh+h^2))-(6-x^2)}{h}\\\\ \frac{(6-x^2-2xh-h^2)-(6-x^2)}{h}\\\\ \frac{6-x^2-2xh-h^2-(6-x^2)}{h}\\\\ \frac{6-x^2-xh-h^2-6+x^2}{h}\\\\[/tex]
[tex]\frac{(x^2-x^2)+(6-6)-2xh-h^2}{h}\\\\ \frac{(0)+(0)-2xh-h^2}{h}\\\\ \frac{-2xh-h^2}{h}\\\\ \frac{h(-2x-h)}{h}\\\\ -2x-h[/tex]
Plug in h = 0
then your answer is -2x
Ms. Jan brought cookies for her class. She gave out half of them in the morning. At lunch, she gave out 12 more. She had 10 cookies left. How many cookies did she bring in?
Answer:
Step-by-step explanation:
44
Answer:
Step-by-step explanation:
Let [tex]c[/tex] be the total cookies.
[tex]\frac{1}{2}c+12+10=c[/tex]
[tex]\frac{1}{2}c+22=c[/tex]
[tex]c+44=2c[/tex] (multiplied both sides by 2)
[tex]44=c[/tex] (subtracted c from both sides)
[tex]c=44[/tex]
She began with 44 cookies.
