Find a polynomial of degree 3 with a real coefficient that satisfies the given condition. Zeros: -2, 1, 0; f(2)=32
xz_007 [3.2K]
Its factors would be
(x+2)*(x-1)*(x+0)

x^2 +x -2

x^3 + 0 + x^2 + 0 -2x +0

Equation: x^3 + x^2 -2x
f(2) = 8 + 4 -4

2x^3  + 2x^2  -4x +0
f(2) = 16 + 8 -8

3x^3  + 3x^2  -6x +0
f(2) =  24 +12 -12

4x^3  + 4x^2  -8x +0
f(2) =  32 +16 -16

So, the equation is:
4x^3  + 4x^2  -8x = 0

I need help on this can you help me
miskamm [114]
Phil had 2 quarters, 1 dime and 3 pennies = 63 cents
Paul had 2 nickles = 10 cents

Total 63 + 10 = 73 cents

If Paul had 1 cent more than Phil, then Paul would have 37 cents and Phil would have 36 cents
but Paul had 10 cents 
10 cents + 27 cents = 37 cents

so 
1 quarter and 2 pennies Phil gave to Paul, total 27 cents

Answer

Phi gave Paul 1 quarter and 2 pennies.

What is the return on equity for a firm with 15% return on assets, 10% return on debt, and a .75 debt/equity ratio?
Harman [31]

The return on equity for  the firm is 18.75%.

<h3>Return on equity</h3>

Return on equity=Return on assets +[ (Debt/Equity ratio)×(Return on assets-Return on debt)]

Let plug in the formula

Return on equity=.15+ [(.75)× (.15-.10)]

Return on assets=.15+ (.75×0.05)

Return on assets=.15+0.0375

Return on equity=0.1875×100

Return on equity=18.75%

Therefore the return on equity ratio is 18.75%.

Solve the equation: 13W - 2(4W + 1) = W - 58 *
Sergio [31]

Answer:

W = - 14

Step-by-step explanation:

13W - 2(4W + 1) = W - 58

13W - 8W - 2 = W - 58

13W - 8W - W = 2 - 58

4W = - 56

W = - 56 : 4

W = - 14
