Answer:

Step-by-step explanation:
we are given a quadratic equation
Let's assume formula of vertex form of parabola as

where vertex is (h,k)
we are given
vertex =(11,-2)
so, h=11, k=-2
now, we can plug it

now, we are given zeros at x=10 and x=12
we know that zeros will be x=10 , y is 0
so, we can plug x=10 and y=0 and solve for 'a'



now, we can plug it back
and we get

so, we get quadratic equation as

240 centimeters why because i need point I don’t rlly know
Im assuming there is exponents so if im assuming correctly, then the answer would be 6x^4 - x^3 - 5x^2 + 10x + 5 because you would combine like terms.

The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
