Answer:
With F represent the variable of interest:
Step-by-step explanation:
For this case we have a normal limits for the temperature Range. The minimum is 660 F and the maximum 790 F.
We can find the midpoint of this interval like this:
And the difference between the midpoint and the limits are:
So then we can create the following inequality:
With F represent the variable of interest.:
Answer:
and f as shown below.
Use these lengths to find cosx, sinx, and tanx.
Step-by-step explanation:
Answer:
the answer is 1.3
Step-by-step explanation:
12+4.3 is 16.3
16.3-15 is 1.3
My guess is that you're doing the Law of Cosines? You have everything you need for that except the angle theta, which is the thing you need to find. It's set up like this: (8)^2 = (10)^2 + (5)^2 -[2(10)(5)cos A] I used A instead of theta. Doing that math, you have: 64 = 100 + 25 -[ 100 cos A]; 64 = 125 - 100 cos A;
-61 = - 100 cos A; -61 / -100 = cos A; .61 = cos A. Now use your inverse function on your calculator to find cos^-1(.61) and that equals 52.4
