The formula for the growth rate is given by
Now when b is greater than 1 , then it is increasing function
and when b is less than 1 , then it is decreasing function.
Now in the function
here value of b is 0.88 , which is less than 1 , so it is decreasing function
And decay rate is given by
1-r = 0.88
Subtract 1 from both sides
-r = 0.88-1
-r = -0.12
r = 0.12
or r= 12%
It means it is decreasing at a rate of 12%
Hence Option C is correct
C.The price of the boat decreases by 12% every year.
Answer:
A: 180°, semi circle
Step-by-step explanation:
We are told that MK and HL are the diameters.
By Inspection, it is clear that MHK will be a semi circle.
The angle of that chord will be 180° since sum of angles on a straight line is 180°.
Answer is option A
Answer:
250
Step-by-step explanation:
Every number is multiplied by 5
2 x 5 = 10
10 x 5 = 50
50 x 5 = 250
