Answer:
C. infinitely many solutions
Step-by-step explanation:
every point of the line (or lines) is a solution.
so, infinitely many.
Answer:
The object will hit the ground after 9 seconds.
Step-by-step explanation:
We are given the function:
Where <em>h</em> is the height of the object after time <em>t</em>, <em>v</em>₀ is the initial velocity, and <em>h₀</em> is the initial height.
An object is thrown upwards from a height of 720 feet and an initial velocity of 64ft/s. We can to determine how long it will take for the object to reach the ground.
Hence, <em>h₀ </em>= 720 and <em>v₀</em> = 64. Substitute:
When the object reaches the ground, its height <em>h</em> above the ground will be zero. In other words:
Solve for <em>t: </em>
<em /><em />
<em />
Since time cannot be negative, we can ignore the first solution.
In conclusion, the object will hit the ground after 9 seconds.
Answer:
x=67.4
y=22.6
Step-by-step explanation:
<span>You are given the graph of four straight lines, P, Q, R, and S. You are asked to find which line corresponds to the function of f(x) = 4x - 3. The easiest way to answer this is to plug in the values of the coordiante points used for each graph.
</span>f(x) = 4x - 3 = y
y = 4x - 3
<span>for graph of line S we have the coordinates (0, -3) and (2, 5)
</span>(0, -3)
-3 = 4(0) - 3
-3 = -3
(2,5)
5 = 4(2) - 3
5 = 8 - 3
5 = 5
So the answer is the graph of line S.
