Answer:
b Superscript positive
Step-by-step explanation:
Negative exponents in the denominators can be evaluated by moving the function from the denominator to the numerator and changing the power from negative to the positive.
We have
1/b⁻² = b²
Moving the function with a power from denominator to numerator or from numerator to denominator changes the sign of the power. It is not equal to zero.
This is the property of exponents.
Answer:
Option C)
Step-by-step explanation:
We are given the following in the question:
I is the annual income of a person in a country R
2 percent of one’s annual income =
1 percent of one’s annual income =
Average of 100 units of Country R’s currency and 1 percent of one’s annual income.
Income tax =
2 percent of one’s annual income + Average of 100 units of Country R’s currency and 1 percent of one’s annual income.
Thus, income tax is given by

For the fulcrum to balance, the product of weight and distance on both sides of the fulcrum must be the same.
Let d1= x. since total distance is 12, we can write d2 = 12 - x
for the fulcrum to balance:
60x = 50(12 - x)
60x = 600 - 50x
110x = 600
x = 5.45
Thus, d1= 5.45
and
d2= 12 - d1 = 12 - 5.45 = 6.55
d1 = 5.45
d2 = 6.55
The rate of change is 110 percent.
