Answer:

Step-by-step explanation:
Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.
Given:
Number of bees is modeled by the function 
The daily high temperature is increasing at a rate of 2 °F per day when the number of bees spotted is 100.
To find:
rate of change of number of bees when 100 bees are spotted
Solution:

Differentiate with respect to t,

Put 

At x = 100, 
I have no clue because I am not trying and I am too lazy to answer ;)
Answer:
4. 40°
5. 15
6.
I hope this helps. I don't know the last one.
The answer : 4 sin c sin b sin a
Step by step
Formula = A+b+c = 180
B+c = 180-A
C+A= 180-B
A+B= 180-c
2 sin c • 2 cos a-b+c/ 2 cos a-b-c / 2
4 sin c cos 180-2b/2 cos a-(180-a)/ 2
4 sin c cos (90-b ) cos ( A-90)
4 sin c sin b sin A
Answer:
1/13
Step-by-step explanation:
there are 4 jacks in a deck of 52 cards
therefore probability of picking a jack:
4/52 = 1/13
