Solve for s. 1/2 s = 7/2. A 1/7. B 2/7. C 3. D 7.

Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

$\frac{1}{2} s = \frac{7}{2} \\ \\\frac{(\frac{1}{2}s)}{\frac{1}{2}} = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{7}{2} * \frac{2}{1} \\ \\\\s = 7$

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.

Genesis throws a ball up in the air. The graph below shows the height of the ball hh in meters after tt seconds. Find the interv

Juli2301 [7.4K]

We conclude that the interval in which the function decreases is (1.5, 3]

<h3>In which interval is the ball's height decreasing?</h3>

The ball is decreasing when the graph, reading from left to right, is going downwards.

Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.

And we can see that the vertex is at x = 1.5

And we also see that the graph of the function ends at x = 3.

Then we conclude that the interval in which the function decreases is (1.5, 3]
