(3, 5pi/3) = (3cos 5pi/3, 3sin 5pi/3) = (1.5, -2.6)
Answer:
Step-by-step explanation:
slope of line through (6,-1) and (11,2) = (-1 - 2)/(6 - 11) = 3/5
slope of line through (5,-7) and (8,-2) = (-7 - (-2))/(8 - 5) = -5/3
product of the slopes = -1, so the lines are perpendicular.
Answer: A) multiply the input by 6.
Step-by-step explanation:
Given:
The graph of an exponential function.
To find:
The function in the form of
.
Solution:
The general form of an exponential function is
...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,



For x=1 and f(x)=7,

Putting a=4, we get


Substitute a=4 and
in (i).

Therefore, the required exponential function is
.
Divide each by 12 to get its speed for one minute. 3,600/12=300 12/12=1. It is going 300?? in 1 minute. Hope this helped!
