Answer:
A(2/9, 1/3)
B(2/3, -1/3)
slope = -1.5
Step-by-step explanation:
A graph can show the coordinates of interest: A(2/9, 1/3); B(2/3, -1/3).
Rearranging the equation to slope-intercept form, we have ...
3y = -4.5x +2
y = -1.5x +2/3
The slope is -1.5.
Answer:
14.1m above the sea level.
Step-by-step explanation:
h(t)=−4.9t²+4t+15, t in seconds
When t=0s, h(0)=15m (height of cliff), so it means that h is measured from the sea level.
After 1 second: h(1)=-4.9+4+15=14.1m above the sea level.
Answer:
18^5
