Answer:
Step-by-step explanation:
I used the following points.
x y
-10 -1
-5 -1
-1 0
0 1
1 3
2 7
3 15
From which I think the graph turns out to be y = 2^(x + 1) - 1
-6 2
0 5
1 8
2 14
From which I get y = 3*2^x + 2
You may say to me that's all well and good, but how did you do it? You have to take a few wild guesses. It also helps to know where the question came from. What were you studying when the graphs were assigned?
I don't think there is a magic bullet for figuring these out. You just have to keep on trying until you get it.
One thing is certain. You should work on the y intercept (5) and the distance above or below the x axis. The distance above the x axis is 2 which means that c = 2.
y = a*b^x + c
c is the constant above or below the x axis. You need only read the graph to get the result. a is the hardest to find, but it will be just slightly easier when you let x = 0.
a + c = 5 Since c = 2 a must be 3
75 degrees in full form is 108/5 degrees

Step-by-step explanation:
Answer: At 01:05 p.m. it will overlap again.
Explanation:
Since there are 22 times in a day the minute and the hour hands overlap.
During the first half of the day , it overlaps 11 times and during the rest of the day it overlap 11 more times.
At noon, the minute and the hour hands overlap and after that it will happen at 01:05 p.m.
Since the minute hand completes a full circle in one hour, so it forms 6 degrees per minute .
So, at 01:05 p.m. it will overlap again.
Answer:
The height of the lighthouse is 
Step-by-step explanation:
Let
h -----> the height of the lighthouse
we know that
The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse
so
Solve for h
