Elsa’s friend borrows $400 with an interest rate of 1.5%. How much interest will she pay after 4 years?

Formula I = P x r x t

p is the principal amount, $400.00

r is the interest rate 1.5% a yea (0.015 in decimal)

t is time involved 4 years

so t is 4 year time periods

To find the simple interest we multiply 400 x 0.015 x 4 to get $24.00

so if you borrowed the $400 dollars you would now owe $424

so it's $24 interest or $424 since it's usually added to the principal

answer and step-by-step explanation:

400 =

1.5% = 0.015%

4years = 0.015%

(correct me if im wrong)

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
