Y=-8(x+3)(x-2) in standard form
Sliva [168]

Answer:

\large\boxed{y=-8x^2-8x+48}

Step-by-step explanation:

The standard form of an equation of a parabola:

y=ax^2+bx+c

We have

y=-8(x+3)(x-2)         <em>use distributive property: a(b + c) = ab + ac</em>

y=\bigg((-8)(x)+(-8)(3)\bigg)(x-2)

y=(-8x-24)(x-2)        <em>use FOIL: (a + b)(c + d) = ac+ ad + bc + bd</em>

y=(-8x)(x)+(-8x)(-2)+(-24)(x)+(-24)(-2)

y=-8x^2+16x-24x+48        <em>combine like terms</em>

y=-8x^2+(16x-24x)+48\\\\y=-8x^2-8x+48

Susan Marciano invested part of her 19000 bonus in a fund that paid an 11% profit and invested the rest in stock that suffered a
ioda

The amount invested at 11% is ​$5,000

The amount invested in stock is ​$14,000

What is the net profit on both investments?

The profit of each investment is the rate of return or loss multiplied by the amount invested

Let us assume that x was invested at 11% and the remaining 19000-x was invested at a loss rate of 3%

net profit=(11%*x)+(19000-x)*-3%

net profit=130

130=(11%*x)+(19000-x)*-3%

130=0.11x-570+0.03x

130=0.14x-570

130+570=0.14x

700=0.14x

x=700/0.14

x=$5,000

Amount invested in stock=19000-x

Amount invested in stocks=19000-5000

Amount invested in stocks=$14,000
