Answer:
A
Step-by-step explanation:
We want to solve the equation:

To do so, we can rewrite the equation.
Recall the double-angle for sine:

By substitution:

Distribute:

We can subtract 3cos(x) from both sides:

And factor:

Hence, our answer is A.
*It is important to note that we should not divide both sides by cos(x) to acquire 10sin(x) = 3. This is because we need to find the values of x, and one or more may result in cos(x) = 0, and we cannot divide by 0. Hence, we should subtract and then factor.
Answer:
$1.51
Step-by-step explanation:
1.25 lb. of dried fruit : 
0.5 lb. of cereal : 
Cost = $2.30 + $1.19 = 3.49
Money = $5
$5 - $3.49 = $1.51 in change
Answer:
60
Step-by-step explanation:
1/3 of 60 is 20
in other words
20 x 3 = 60
Answer:

Step-by-step explanation:
The area of a sector with measure
in degrees is given by
, where
is the radius of the sector.
What we're given:
Solving, we get:

*Notes:
- units should be in square meters (area)
- the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
