(c) Marlene invests $550 at a rate of 1.9% per year compound interest Calculate the amount Marlene has after 10 years.

$ 663.90

Step-by-step explanation:

Calculate the amount (A) using

A = P

where P is the principal, r is rate of interest and t is time in years

Here P = $550, r = = 0.019 and t = 10 then

A = 550

   = 550

    = $ 663.90

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)
