Mandy throws a stone off a bridge into the river below. The stones height above the water in meters h(t) after t seconds is measured using function h(t) = -16t^2+32t+43. What is the initial height of the stone?

The initial height of the stone is 43 meters.  

Step-by-step explanation:

We have, the height followed by stone as a function of time t is given by :

It is required to find the initial height of the stone. We know that initial height means height when t = 0. Putting t = 0 in above equation such that,

So, the initial height of the stone is 43 meters.  

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
