The population of a town is increasing at an annual rate of 6.2%. The city council believes they will have to add
another elementary school when the population reaches
110,000. If there are currently 56,000 people living in
the town, how long do they have before the new school
will be needed to the nearest tenth of a year?
[ use A = P(1 + r)']
(1) 11.2
(2) 1.8
(3) 109.2
(4) 3.2

the answer is 13 cm

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
