An equation of a circle is x2 − 8x + 16 + y2 + 10y + 25 = 81 What is the radius of the circle? What is the center of the circle?

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
