Answer:
k = 9
length of chord = 2/3
Step-by-step explanation:
Equation of parabola: 
<u />
<u>Part 1</u>
If the curve passes through point
, this means that when
, 
Substitute these values into the equation and solve for
:


Apply the exponent rule
:



<u>Part 2</u>
- The chord of a parabola is a line segment whose endpoints are points on the parabola.
We are told that one end of the chord is at
and that the chord is horizontal. Therefore, the y-coordinate of the other end of the chord will also be 1. Substitute y = 1 into the equation for the parabola and solve for x:





Therefore, the endpoints of the horizontal chord are: (0, 1) and (2/3, 1)
To calculate the length of the chord, find the difference between the x-coordinates:

**Please see attached diagram for drawn graph. Chord is in red**
Answer: y=85
Step-by-step explanation: Substitute all x's in the equation with 8. y=2.5(8)+65. And solve y=85
Answer:
Answers are: (x+3)(x+5) = 0
So first zero: x+3 = 0 so x = -3
Second zero: x+5 = 0 so x = -5
so zeros are: x = -5 and -3
