Answer:
-1/√2
Step-by-step explanation:
According to trigonometry identity
cos(A+B) = cosAcosB - sinA sinB
Given the expression
(cos92°)(cos133°)-(sin92°)(sin133°)
This can be expressed as cos(92+133) where A = 92, B = 133
(cos92°)(cos133°)-(sin92°)(sin133°)
= cos(92+133)
= cos225
= -0.7071
= -1/√2
Hence the exact value is -1/√2
Answer:
The radius is growing at a rate of 
ft per minute.
Step-by-step explanation:
From the information given we know that
And we know as well that .
Since everything is changing with the time we can compute the implicit derivative and we would get that
We are told that we are looking for how fast is the radius growing at the instant when the radius has reached 1 ft, therefore 
And when we solve for
Answer:
See explanation
Step-by-step explanation:
You didn't specify, the underlined digit.
Assuming the underlined digit is 6.
Then we want to round 199,602 to the nearest hundred.
Since the next digit is 0, and 0<5, We round off to get:
199,602=199600 to the nearest 100.
