A worker earned a 3% increase in her annual salary for each of 5 years. They plan to continue working in their position for additional n years. If they continue to earn a 3% increase in their annual salary, which statement describes the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year?

the answer is true.

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
