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

The answer is D because side 3 is to far from side 1 and side 2 because you cant make a triangle out of those measurements
Here's a tip
if the sum of side 1 and side 2 are greater than side 3 then it forms a triangle
Answer:
-5 and initial value is -1
Step-by-step explanation:
Slope= y2-y1/x-x1
-11-(-1)/2-0
-10/2
-5
Initial value is y-intercept where x is 0 (0,y)
so
(0,-1) is starting point
Answer: 40 minutes
Step-by-step explanation:
2/5 = .4 so it would be 40 minutes
Answer:
The horizontal distance between the parking lot and the launch site is 470 meters
Step-by-step explanation:
Let
x-----> the horizontal distance between the parking lot and the launch site
we know that
The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance
so
tan(12°)=100/x
Solve for x
x=100/tan(12°)=470 meters
