Answer:
Step-by-step explanation:
Given:
Need:
First, let's look at the identities:
sum: 
difference: 
The question asks to find sin(A - B); therefore, we need to use the difference identity.
Based on the given information (value and quadrant), we can draw reference triangles to find the simplified values of A and B.
sin(A) = 
cos(A) = 
sin(B) = 
cos(B) = 
Plug these values into the difference identity formula.
Multiply.
Add.
This is your answer.
Hope this helps!
Answer: 22.4

32.6 - 10.2 = 22.4
Answer: To find a residual you must take the predicted value and subtract it from the measured value.
Step-by-step explanation:
Answer: $768.50
Step-by-step explanation:
If $725 was the price before sales tax, $768.50 would be the total amount after the 6% sales tax increase.

A turning point occurs when the velocity is equal to zero, but the acceleration is not equal to zero.
t(x)=(x+5)^3+7
dt/dx=3(x+5)^2
d2t/dx2=6(x-5)
dt/dx=0 only when x=-5
However, since d2t/dx2(-5)=0, this point is an inflection point, not a turning point.
So there is no turning point for this function.
Now in this problem, it is even easier than the above to show that there is no turning point. A turning point by definition is when the derivative or velocity changes sign. Since in this case v=3(x+5)^2, for any value of x, v≥0, and thus never becomes negative, so it never changes from a positive to negative velocity because velocity in this instance is a squared function.
