The ball describes a parabola, as you can see in the attached picture. So, the point where the ball strike the ground is the point where the parabola meets the x axis. In fact, the x-axis is the set of points where y=0, which means that the ball has height 0 or -again- it hits the ground.
So, we have to set y=0 in our equation and look for the positive solution. We have
And the positive solution is
So that's the distance from the child where the ball strikes the ground.
Answer:
-2
Step-by-step explanation:
using the slope formula with these two points gives me a slope of -2. Hope that helps!
Solution: The value of temperature is -79.6 degree fahrenheit.
Explanation:
The temperature is given in degree celsius and we have find the temperature in degree fahrenheit. The formula to convert the degree celcius in degree fahrenheit is given below,
Where, F is temperature in degree fahrenheit and C is temperature in degree celsius.
Since it is given that the temperature is -62 degree celsius. So put in the above formula.
Hence the value of temperature is -79.6 degree fahrenheit.
