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
If it’s an angle I think 90% but if not maybe 24 all around
The answer to the question is B (the second option 4:2)

Answer:
Option A) 
Step-by-step explanation:
we have
![\sf{\dfrac{\sqrt[7]{x^{2}}}{\sqrt[5]{y^{3}}}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cdfrac%7B%5Csqrt%5B7%5D%7Bx%5E%7B2%7D%7D%7D%7B%5Csqrt%5B5%5D%7By%5E%7B3%7D%7D%7D%7D)
we know that
![\sf{\sqrt[7]{x^{2}}=x^{\frac{2}{7}}}](https://tex.z-dn.net/?f=%5Csf%7B%5Csqrt%5B7%5D%7Bx%5E%7B2%7D%7D%3Dx%5E%7B%5Cfrac%7B2%7D%7B7%7D%7D%7D)
![\sf{\sqrt[5]{y^{3}}=y^{\frac{3}{5}}}](https://tex.z-dn.net/?f=%5Csf%7B%5Csqrt%5B5%5D%7By%5E%7B3%7D%7D%3Dy%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D%7D)
substitute in the expression
