Amir invests $4,000 in a 5-year cd paying 3.5% interest. how much interest will he make on the cd in 5 years? the simple interest formula is i=prt.

$700

Step-by-step explanation:

First, convert the rate into a decimal

r = R/100 = 3.5%/100 = 0.035 per year,

then, solving our equation

I = 4000 × 0.035 × 5 = 700

I = $ 700.00

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
