Answer:
B. 2cos3θsinθ.
Step-by-step explanation:
Use the identity
sin x - sin y = 2 [cos(x + y)/2]sin [x - y)/2].
So we have:
sin4θ - sin2θ = 2 cos (4θ+2θ)/2 sin (4θ-2θ)/2
= 2cos3θsinθ.
Answer:
The answer to your question is 17/24 gallon
Step-by-step explanation:
Data
total volume = 1 gallon
She uses 3/8 gallon and 1/3 gallon
Process
1.- To find the answer, just sum up the water she used to water her roses and the volume she used to water her geraniums.
3/8 + 1/3 =
- Look for the Least common factor
8 x 3 = 24 LCF = 24
- Solve the fraction
3/8 + 1/3 = (9 + 8) / 24
= 17/24
2.- Conclusion
She used 17/24 gallon to water her flowers.

Answer:
probability that the card is a Queen or a diamond= 0.3269
Step-by-step explanation:
There are 4 queen in a deck of cards and 13 diamond in a deck of cards.
And a deck of cards contains 52 cards total.
Probability of the card selected to be a queen = number of queen/total number of cards
Probability of the card selected to be a queen =4/52
Probability of the card selected to be a queen= 1/13
Probability of the card selected to be a diamond= number of diamond/ total number of cards
Probability of the card selected to be a diamond=13/52
Probability of the card selected to be a diamond=1/4
probability that the card is a Queen or a diamond= Probability of the card selected to be a queen + Probability of the card selected to be a diamond
probability that the card is a Queen or a diamond= 1/13+1/4
probability that the card is a Queen or a diamond= 0.3269
Answer:
x = 6.5
Step-by-step explanation:
Since all angles in a triangle adds up to 180°, we have:
10x - 10 + 10x + 8 + 8x = 180
28x - 2 = 180
28x = 182
x = 182/28 or 6.5
