Answer:
The stone fell in the air for 7 seconds and fell in the water for 5 seconds.
Step-by-step explanation:
time taken in water is 12 - 7 = 5 seconds
checking; 16*7 + 3*5 = 127 (proven
<h3>The y intercept is
-1</h3>
We can say that the y intercept is at the location (0,-1)
This is where the graph crosses the vertical y axis. This is 1 unit below the origin.
This is assuming each tickmark on the grid represents 1 unit.
With the first one, you just plug the numbers inside the parentheses into f(x). Therefore:
f(-2)=40
f(-1)=18
f(0)=8
f(1)=10
f(2)=24
For the second one, you look at the table and find where x=1. The number there is 24, so therefore, f(1)=24
1) cscΘ = - 2
=>
1
------ = - 2
sinΘ
=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant
=> Θ = 180° + 30° = 210°
and Θ = 360° + 30° = 330°
2) tan Θ = √3
=> Θ = 60° and Θ = 180° + 60° = 240°
