Answer:
Her statement is not correct.
Step-by-step explanation:
It is not correct because if you simplify 10/4 it comes out to 5/2 therefore 5/2=5/2.
Beth and May run the same amount.
7/10 > 4/10 because 7/10 is bigger than 4/10
7/10 = 0.7
4/10 = 0.4
Answer:
sin(A-B) = 24/25
Step-by-step explanation:
The trig identity for the differnce of angles tells you ...
sin(A -B) = sin(A)cos(B) -sin(B)cos(A)
We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.
And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.
Then ...
sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25
The desired sine is 24/25.
