Use the half-angle formulas to find the exact value of the trigonometric function sin 15°
Answer:
sin 15° = 0.2588
Step-by-step explanation:
The half angle formula is:
[tex]\sin{(\frac{x}{2})} = \pm \sqrt{\frac{1 - \cos{x}}{2}}[/tex]
sin 15°
The double of 15º is 30º. First quadrant, so the sine is positive.
[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}}[/tex]
Since [tex]\cos{30} = 0.866[/tex]
[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}} = \sqrt{\frac{1 - 0.866}{2}} = 0.2588[/tex]
sin 15° = 0.2588

Nathaniel is going to invest $22,000 and leave it in an account for 20 years.
Assuming the interest is compounded continuously, what interest rate, to the nearest
tenth of a percent, would be required in order for Nathaniel to end up with $33,000?
Answer:2.0%
Step-by-step explanation:
The interest rate required to get a total amount of $33,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 20 years is 2.048% per year.
What is the interest rate?r = n[(A/P)1/nt - 1]
r = 1 × [(33,000.00/22,000.00)1/(1)(20) - 1]
r = 0.0204802
Then convert r to R as a percentage
R = r * 100
R = 0.0204802 * 100
R = 2.048%/year
The interest rate required to get a total amount of $33,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 20 years is 2.048% per year.
The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR (APR).To learn more about compound interest refer to:

If you multiply a number by 3 and then add 40, the result is the same as if you add 17 to the number and then multiply by 2. What is the result if you subtract 9 from the number and then multiply by 4? .
Answer:
The number is -6
The second operation is -60
Step-by-step explanation:
Let the number be x.
Solving (a): The value of x
Operations 1:
Multiply by 3: 3x
Add 40: 3x + 40
Operations 2:
Add 17: x + 17
Multiply by 2: (x + 17) * 2
To find x, equate both operations.
[tex]3x + 40 = (x + 17) *2[/tex]
[tex]3x + 40 = 2x + 34[/tex]
Collect like terms
[tex]3x - 2x = 34 - 40[/tex]
[tex]x = -6[/tex]
Solving (b):
Operations:
Subtract 9: [tex]x - 9[/tex]
Multiply by 4: [tex](x - 9) * 4[/tex]
This gives:
[tex](x - 9) * 4 = (-6 - 9) * 4[/tex]
[tex](x - 9) * 4 = -15 * 4[/tex]
[tex](x - 9) * 4 = -60[/tex]

This is function notation and I have no idea how to do it. I need answers.
Answer:
So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.
f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given
f(5) = 3(5) - 4
f(5) = 15 - 4
f(5) = 11
f(2) = 3(2) - 4
f(2) = 6 - 4
f(2) = 2
f(1) = 3(1) - 4
f(1) = 3 - 4
f(1) = -1
f(10) = 3(10) - 4
f(10) = 30 - 4
f(10) = 26
f(-1) = 3(-1) - 4
f(-1) = -3 - 4
f(-1) = -7

What is Pythagorean theorem?In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
What is Right triangle?A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.
Given,
Length of the ladder = 2.9 meter
Distance from base to wall = 1.3 meter
Draw the figure using the given data
Apply Pythagorean theorem
[tex]AB^{2}+BC^{2}= AC^{2}\\ AB^{2}=AC^{2}-AC^{2} \\ AB^{2}=2.9^{2}-1.3^{2}\\ AB^{2}=6.72\\ AB=\sqrt{6.72}[/tex]
AB=2.59 meter
Hence, the length up the wall does the ladder reach is 2.59 meter

Areceli is a chef for a catering company. The guests at a banquet had a choice of entrées: chicken or lasagna.
Areceli prepared three times as many chicken dinners as lasagna dinners, and there were 96 guests. How many chicken dinners were served?
Answer:
93x6=anser
Step-by-step explanation:
Answer:
72 Chicken Dinners and 24 Lasagna Dinners
Step-by-step explanation:
Since you know that chicken dinners are 3 times as much as lasagna, you know that you must divide 96 by 4. Why? Well we aren't just looking at the chicken dinners itself. IF we were, then we would divide 96 by 3. But in this situation, you have to divide by both the lasagna and the chicken. Adding the parts together, you get 1 and 3, or 4. So, dividing 96 by 4 you get 24. You now know that the amount of lasagna dinners is 24. Chicken dinners are 3 times as much meaning 24 x 3 = 72 chicken dinners.
Algebraic expression ish (x = lasagna dinners):
96 = 3x + x
96 = 4x (divide both sides by 4 now)
24 = x

There are 6 cabbages and 8 carrots in a bag. How many carrots need to be added to make the ratio of
cabbages to carrots 1:3?
Answer:
10 carrots
Step-by-step explanation:
So we have 6:8 which is 3:4, meaning that something needs to be changed
Solve for x assuming that we have 6 cabbages
1/3=6/x
x=18
Now we have 6:18, which is 1:3 simplified
There are already 8 carrots so subtract 8
18-8=10
