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:
13 Raffle tickets
Step-by-step explanation:
Cost for one riffle ticket = 2.50
Total money of Vanessa budgeted for riffle ticket : 34.75
Greatest number of riffle ticket, venessa can with with 34.75
I'll like us to divide 34.75 by 2.5 to get the exact value.
Therefore,
34.75 / 2.5
= 13.9
It therefore implies that, Vanessa will buy a maximum of 13 riffle tickets and still have a change of 2.25
36.96 with the formula 0.24 * 154 = 36.96
