Jayden invested $7,500 in an account paying an interest rate of 5 % compounded continuously. Abigail invested $7,500 in an account paying an interest rate of 4 %
compounded annually. To the nearest hundredth of a year, how much longer would
it take for Abigail's money to double than for Jayden's money to double?

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

answer: idk wbu

step-by-step explanation: umm..

the answer is c.

perimeters = 3√10/5

areas = 90/25

i got it down chief.

26 + 8 = 2*13 + 2*4 = 2*(13+4) = 2*(17)
