How many times does the equation f(x)=2x^2+9x-5 intersect the x-axis
Komok [63]

Answer:

2

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

How do I find the value of WQ
Brut [27]

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
