Answer:
Are you in Connexus ?
Step-by-step explanation:
Answer: $142.5
Step-by-step explanation: If the price is being marked up by 50%, you take 50% or half of the original price of $95, which is 47.5, and add it to your original price.
95 + 47.5 = 142.5
A or c is the correct answer
2 feet is the answer if the flag is 4 by 6 other wise it would be a feet and 3 inches
Given expression is sin(45)sin(15)
this expression best matches with left side of the formula:
2 sin(A) sin(B)= cos(A-B) - cos(A+B)
so we can plug given angles 45 and 15 there
2 sin(45) sin(15)= cos(45-15) - cos(45+15)
2 sin(45) sin(15)= cos(30) - cos(60)
sin(45) sin(15)= [cos(30) - cos(60)]/2
We are getting negative sign and cos in the solution while none of the given choices have same situation so answer will be none of them.
-----------
For cos(75)-cos(15), we will use formula:

Now plug the given angles



Hence choice B is correct.
