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.

The formula for electrical power (P, in watts) is where V is the voltage in volts and R is the resistance in ohms. For a particu

bazaltina [42]

Answer: 4 V

Step-by-step explanation:

The formula for electrical power $P$ is:

$P=\frac{V^{2}}{R}$

Where:

$P=0.5 W$ is the water heater electrical power

$V$ is he water heater voltage

$R=32 \Omega$ is the electrical resistance

Isolating $V$ :

$V=\sqrt{PR}$

$V=\sqrt{(0.5 W)(32 \Omega)}$

Hence:

$V=4 V$
