Step-by-step explanation:
f(x)=2x^2+9x-5
When we are find how many times it intersects the x axis, we are finding the zero's. Set the equation equal to zero
0=2x^2+9x-5
Factor the equation
0 = (2x+1) (x-5)
2*1
1*-5 = -5
2*-5 +1*1 = -9
This checks for the first last and middle terms so we factored correctly
Then using the zero product property
2x+1 = 0 and x-5 =0
2x = -1 x=5
x = -1/2 and x=5
This function crosses the x axis 2 times
Answer:
WQ = 2.67 to the nearest hundredth.
Step-by-step explanation:
The area of triangle PQX = 1/2 * PX * QX.
The area of the rectangle = 8 * YX .
But YX = 2 PX so its area = 8 *2PX = 16*PX.
We are given that area of PQX is 1/6 of the area of WXYZ, so we have the equation:-
16 PX = 6* 1/2*PX * QX
16 = 3QX
QX = 16/3 = 5.33
Finally WQ = WX - QX
= 8 - 5.33
= 2.67
