Recall: SOHCAHTOA
✔️Sin M = Opp/Hyp
Reference angle = M
Opp = 3√21
Hyp = 15
Sin M = (3√21)/15
Sin M = √21/5
✔️Cos M = Adj/Hyp
Reference angle = M
Adj = 6
Hyp = 15
Cos M = 6/15
Cos M = 2/5
✔️Tan M = Opp/Adj
Reference angle = M
Opp = 3√21
Adj = 6
Tan M = (3√21)/6
Tan M = √21/2

Use an Addition or Subtraction Formula to write the expression as a trigonometric function of one number. sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21
Answers
Answer:
sin(3π/7 - 2π/21)
Step-by-step explanation:
Given
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21
Required
Write a trigonometry formula for the expression
Using sine formula, we have:
sin(A - B) = sinAcosB - cosAsinB
The above formula can be applied to the given expression where
A = 3π/7
B = 2π/21
So, the trigonometry formula is:
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21= sin(3π/7 - 2π/21)
Answer:
sin(π/3), exact value √3/2

Answer:
y = [tex](\frac{1}{2})^{-x} +4[/tex]
Step-by-step explanation:
In order to achieve the following transformation we need to do the following. To get the graph to be reflected accross the y-axis we need to change the sign of the x variable. Since the x-variable in this scenario is a positive we would change it to a negative. Next, we want to shift the graph 4 units up. To do this we simply need to add 4 to the entire equation. This would result in the following equation.
y = [tex](\frac{1}{2})^{-x} +4[/tex]
Both of these graphs can be seen in the image below.

Surface area of a cube:
SA = 6a²
Given:
a = 10
Work:
SA = 6a²
SA = 6(10²)
SA = 6(100)
SA = 600
Answer:
600 squared feet
Step-by-step explanation:
This is your answer because in order to find surface area you can use the equation 6s². Which would be 6 times your side length of 10, then to the 2nd power. This is the equation because there are 6 sides in total on your cube and you are trying to find the surface area of all the sides. Since this is a cube all the sides lengths are the same, therefore you times the side length by 6 to include all of the sides. After you get your answer it is squared feet because you have a 3 dimensional shape or 3D shape. Hope this helps!!
6s²=SA
6(10)²=SA
60²=SA
600=SA

Sergio puts flowers in vases. He puts the same number of flowers in each
vase, as shown in the table below. How many vases does Sergio need for
112 flowers?
Answers
Answer:
Since there is so table shown here, I advice you to divide 112 with the number of flowers in each vase. Like for example lets say that the amount of flowers in each vase is 16. You would need to divide 112 and 16. Thats 7. So the "answer" would be 7. Do the same (divide 112) with the amount of flowers you have in your table.
At a particular fast food restaurant, tacos cost $1.29 and
burritos cost $2.19. Michael spent a total of $42.93 at the
restaurant to buy food for a party. If he purchased half as
many burritos as tacos, how many tacos did he buy?
Answers
Answer:
Michael bought 18 tacos and 9 burritos.
Step-by-step explanation:
Since at a particular fast food restaurant, tacos cost $ 1.29 and burritos cost $ 2.19, and Michael spent a total of $ 42.93 at the restaurant to buy food for a party, if he purchased half as many burritos as tacos, to determine how many tacos did he buy, the following calculation must be performed:
1.29 x 20 + 2.19 x 10 = 47.7
1.29 x 16 + 2.19 x 8 = 38.16
1.29 x 18 + 2.19 x 9 = 42.93
So Michael bought 18 tacos and 9 burritos.

Cameron has a balance of $10,200 on his credit card. He threw the card away so he can never use it again. He has 3.5 years to pay off the balance. The interest rate on his card is 21%.
At the end of the 3.5 years, how much money in interest alone will Cameron have paid?
When Cameron finally pays off his credit card, how much will he have paid in all?
Answers
Answer:
the interest is $9,676.91 and the future value amount is $19,876.91
Step-by-step explanation:
The computation is shown below;
The future value is
= Present value × (1 + rate of interest)^number of years
= $10,200 × (1 + 0.21)^3.5
= $19,876.91
Now the interest amount is
= Future value - present value
= $19,876.91 - $10,200
= $9,676.91
Hence, the interest is $9,676.91 and the future value amount is $19,876.91
