Riley earned $21,500 during her first year as an interior designer. each year she work for that company, she earns a 3% raise. find her total earnings during her first seven years on the job.

Calculate her pay every year then add:

Year 1: 21, 500

Year 2: 21,500 x 1.03 = 22,145

Year 3: 22,145 x 1.03 = 22,809.35

Year 4: 22809.35 x 1.03 = 23,493.63

Year 5: 23493.63 x 1.03 = 24,198.44

Year 6: 24198.44 x 1.03 = 24,924.39

Year 7: 24,924.39 x 1.03 = 25,672.12

Total made: 21, 500 + 22,145 + 22,809.35 + 23,493.63 + 24,198.44 + 24,924.39 + 25,672.12 = 164,742.93

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
