Determine the average rate of change in median age per year from 1930 to 1960.
a. -0.5 years of age per year
b. 20 years of age per year
c. -0.05 years of age per year
d. +0.05 years of age per year

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

we know that

1) the inscribed angle measures half of the arc it comprises.

so

m∠dgf= > expression

2) the opposite angles in an inscribed quadrilateral are supplementary angles

so

m∠dgf=

m∠dgf=°

substitute in the expression to find the value of arc ef

therefore

the answer is

the measure of the arc ef is

7 9/10 as an improper fractions is 79/10.

hope it : )
