Abigail tosses a coin off a bridge into the stream below. The distance, in feet, the coin above the water is modeled by the equa
melomori [17]

Answer:

7 seconds

Step-by-step explanation:

Distance of the coin above the water is modeled by the equation

y=-16x^2+96x+112

where x is time taken to cover the distance

Now equating with zero.

0=-16x^2+96x+112\\\Rightarrow 16x^2-96x-112=0\\\Rightarrow x=\dfrac{-\left(-96\right)\pm \sqrt{\left(-96\right)^2-4\times \:16\left(-112\right)}}{2\times \:16}\\\Rightarrow x=7, -1

So, time taken by the coin to hit the water is 7 seconds.

What is the equation of the line with an x-intercept of -2 and a y-intercept of 1?
vaieri [72.5K]

Answer:

the desired line is y = (1/2)x + 1

Step-by-step explanation:

Write these two points as (0, 1) and (-2, 0).

Now, as we go from (-2, 0) to (0, 1), x increases by 2 and y increases by 1.  Thus, the slope, m, of the desired line is m = rise / run = 1 / 2.

Then the desired line is y = (1/2)x + 1 (since b is already given as (0, 1) )

postnew [5]

Answer:

234.25$ : 100 = 252.99$ : x

234.25x = 252.99 x 100

234.25x = 25299

25299 divided by 234.25 is 108
