Answer:

  f(x)·g(x) = x³ +x² -2x -2

Step-by-step explanation:

Substitute the function definitions and simplify.

  f(x)·g(x)

  = (x +1)(x² -2)

  = x(x² -2) +1(x² -2)

  = x³ -2x +x² -2

  f(x)·g(x) = x³ +x² -2x -2

An isosceles trapezoid ABCD with height 2 units has all its vertices on the parabola y=a(x+1)(x−5). What is the value of a, if p
horrorfan [7]

Answer:

a = -0.3575

Step-by-step explanation:

The points A and D lie on the x-axis, this means that they are the x-intercepts of the parabola, and therefore we can find their location.

The points A and B are located where

y=a(x+1)(x-5)=0

This gives

x=-1

y=5

Now given the coordinates of A, we are in position to find the coordinates of the point B. Point B must have y coordinate of y=2 (because the base of the trapezoid is at y=0), and the x coordinate of B, looking at the figure, must be x coordinate of A plus horizontal distance between A and B, i.e

B_x=A_x+\frac{2}{tan(60)} =-1+\frac{2\sqrt{3} }{3}

Thus the coordinates of B are:

B=(-1+\frac{2\sqrt{3} }{3},2)

Now this point B lies on the parabola, and therefore it must satisfy the equation  y=a(x+1)(x-5).

Thus

2=a((-1+\frac{2\sqrt{3} }{3})+1)((-1+\frac{2\sqrt{3} }{3})-5)

Therefore

a=\frac{2}{((-1+\frac{2\sqrt{3} }{3})+1)((-1+\frac{2\sqrt{3} }{3})-5)}

\boxed{a=-0.3575}

How many solutions does the system of two equations shown have? <br> y=3(x+4) <br> y=3(x-4)
balu736 [363]
There is no solution. if you are using the two equations to solve for y and x.

you can plug one equations into the other.

substituting one of the y gives...
3(x+4)=3(x-4)
÷ both sides by 3 gives x+4=x-4

get x on one side and numbers on the other
x-x =4+4
and x-x will give you a 0 for the left side
therefore 0 = 4+4.. not true.
