Answer:
(-1.5, 2)
Step-by-step explanation:
Add both x coordinates, divide by 2.
(-5) + 2 = -3
-3/2 = -1.5
Add both y coordinates, divide by 2.
5 + (-1) = 4
4/2 = 2
Answer:
A.
Step-by-step explanation:
4 is greater than the exact value of -2 and 4 is greater than -2. The exact values of -2 are 2 and -2. 4 is greater than both 2 and -2. Thus, a is correct.
Answer:
graph attached
Step-by-step explanation:
27x - 15y = 1350
15y = 27x -1350
y = 27/15 x - 1350/15
y = 9/5 x - 90
y = mx + b y intercept (b) = -90
y=0 x = 90 * 5/9 = 50 x intercept
Answer:
(a)Time taken to reach the ground, x=6 seconds
(b)Maximum height of the arrow during its flight =101.25 feet
Step-by-step explanation:
Given the quadratic function which models the flight of the arrow:

Where:
- y represents the vertical height of the arrow, in meters; and
- x represents the time, in seconds.
(a)Positive Zero

In 6 seconds, the arrow will hit the horizontal plane, i.e. the ground.
(b)

Comparing with the vertex form:

Our vertex, (h,k)=(1.5, 101.25)
Maximum Value of y=101.25
The maximum value of y represents the maximum height of the arrow during its flight, which is 101.25 feet.
