Answer:

A. 159.25

Step-by-step explanation:

Semicircle area:

A = 1 /2 (3.14(5^2))

A = 1 /2 (3.14)(25)

A = 1 /2 (78.5)

A = 39.25

Trapezoid area:

A =  10+20 /2 (8)

A = 120

Area of the figure:

39.25+120 = 159.25

Consider the function g(x)=2x^3+7x^2+x-10-5/2 is a root of g(x). Find all of the roots of g(x)
erik [133]
If -5/2 is a root of that 3rd degree polynomial, then when we do synthetic division on it we will get a remainder of 0, and the resulting numbers from our math will then become the coefficients to a new polynomial, one degree less than what we started with, called the depressed polynomial.  Put -5/2 outside the "box" and the coefficients inside:  -5/2  (2   7   1   -10).  Bring down the 2 and multiply it by -5/2 to get -5.  Put that -5 up under the 7 and add to get 2.  Multiply that 2 by the -5/2 to get -5.  Put that -5 up under the 1 and add to get -4.  Multiply that by -5/2 and get 10.  Put that 10 up under the -10 and add to get a remainder of 0.  Those bolded numbers now are the coefficients of our new polynomial, one degree less than what we started with.  That polynomial is 2x^2+2x-4.  Now we need to factor that to find the other 2 roots to our polynomial.  If we factor a 2 out we have 2( x^{2} +x-2),That factors easily to 2(x+2)(x-1).  That gives us x+2=0 and x = -2, x-1=0 and x = 1.  The 3 solutions or zeros or roots are -5/2, -2, 1.  There you go!

In total, you owed them 28.21, and so you can subtract the amount you paid from the total:

28.21 - 25.95 = 2.26

So, you owe them $2.26 now.
