Jose invested $5000 into a fund with an interest rate of 4.8%. how much interest would he earn after 2 years? a) $240 b) $24,000 c) $480 d) $48,000

C) $480  

Step-by-step explanation:

Given: Jose invested $5000 into a fund with an interest rate of 4.8%.

Therefore, Principal amount (P)$5000

Rate of interest = 4.8%

In decimal rate of interest(r)=0.048

Time (t)= 2 years

We know that the simple interest is given by

Hence, the interest after 2 years = $480

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
