Answer:
Option C and option D
Step-by-step explanation:
we have that
This is the equation of a vertical parabola open upward
The vertex is a minimum
Convert the equation into vertex form
Complete the square
----> equation of the parabola in vertex form
The vertex is the point (2,1)
therefore
when the bird is 2 feet away from the first fence post, it reaches its minimum height of 1 foot
A defines the function
f(1) = - 8 ×( = - 8 × 1 = -8
f(2) = - 8 ×( = -
= - 20
f(3) = - 8 ×( = - 8 ×
= - 50
f(4)= - 8 ×( = - 8 ×
= -125
f(5) = - 8 ×( = - 8 ×
= -
Answer:
slope = - 6, y- intercept = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
0 = 2x - +
y ( multiply through by 3 to clear the fractions )
0 = 6x - 5 + y ( subtract 6x - 5 from both sides )
- 6x + 5 = y , that is
y = - 6x + 5 ← in slope- intercept form
with slope m = - 6 and y- intercept c = 5
