5 Gretchen borrowed $50 from her parents for 3 months. They charged her 14% interest. How much does she need to pay her parents

sergij07 [2.7K]

Step-by-step explanation:

simple interest = principal×rate×time

S.I = $50×(14÷100)×3

S.I=$50×0.14×3

S.I=$21

Amount= principal + simple interest

If f(x)= x-6 and g(x)=x^1/2(x+3), find g(x)xf(x)

Roman55 [17]

Answer:

$f(x)= x-6\\g(x) = x^\frac{1}{2} (x+3)\\\left(x-6\right)\left(x^{\frac{1}{2}}\left(x+3\right)\right):\quad x^{\frac{5}{2}}-3x^{\frac{3}{2}}-18x^{\frac{1}{2}}\\x^2\sqrt{x}-3x\sqrt{x}-18x^{\frac{1}{2}}\\$

Factor and you get

$x^\frac{1}{2} (x-6)(x+3)$

Hope this helps!!!
