Answer:
Option (B).
Step-by-step explanation:
Percentage change between two numbers a and b can be calculated by the formula,
% change = 
Where, (b - a) = Change in values
a = Initial value
If a = 16 and b = 20
Percentage change between 16 and 20 will be,
= 
= 
= 25%
If a = 20 and b = 16,
Percentage change = 
= 20%
Therefore, %change between 16 and 24 may be 16% or 20%.
Option (A),
= 25%
Option (B),
= 1.25 - 1 × 100
= 1.25 - 100
= -98.75%
Option (C),
= 25%
Option (D),
= 20%
Therefore, we can not use the calculation used in Option (B).
The arc measure, which corresponds to the central angle measure, is always twice the subtended angle.
So 60 is twice a,
Answer: a=30
84 is twice b
Answer: b=42
60 + 100 is twice c,
Answer: c=80
d is what's left of the circle, total 360 degrees,
d = 360 - 84 - 60 - 100 = 116
Answer: d=116
Answer:
4.
Step-by-step explanation:
We are asked to find the value of expression 
at 
.
First of all, we will find the derivative of the given expression using "Quotient Rule of Derivatives" as shown below:
Therefore, our required derivative is .
Now, we will substitute in our derivative to find the required value as:
Therefore, the value of expression at is 4.
Answer:
32
Step-by-step explanation:
First divide 72 by 9 which is 8. Then multiply that by 4 which is 32
