Im struggling with this one as well could someone help out?
guapka [62]
The reflection is happening over the x axis (horizontal axis)

Any y coordinate that is positive turns negative, and vice versa

For example: (1,2) ---> (1,-2)

In general, the rule is (x,y) ---> (x,-y)

So the answer is choice C

A projectile is fired straight up from ground level with an initial velocity of 112 ft/s. Its height, h, above the ground after
PtichkaEL [24]

Answer:

Step-by-step explanation:

We can do this the easy way and just set up an inequality and let the factoring do the work for us. The inequality will look like this:

-16t^2+112t>192 We will move the constant over and get

-16t^2+112t-192>0 and when you factor this you get that

3 < t < 4

Between 3 and 4 seconds is where the projectile reaches a height higher than 192 feet. With a little more work and some calculus you can find the max height to be 196 feet.
