Step-by-step explanation:
Answer:
B
Step-by-step explanation:
if you multiply m by 2 you get 260we now want to subtract this from 360 to get 100 then we divide that by 2 to get angle n∠BEF= 50°.
We know angle k∠EBF= 90° so we now end up with adding angle ∠BEF with ∠EBF to get 140 to get angle x we subtract 140 from 180 to get 40. x=40°. so B is the correct answer
Answer:
m = 1/3
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:
The average rate of the function f(x) from x=a to x=b is given by:
From the question, the exponential function goes through (0,30) and (20,80).
This implies that f(0)=30 and f(20)=80
Therefore the average rate of change from x = 0 to x = 20 is
The second choice is correct
