Kyle drops a ball from a height of 15 feet above the ground. The function h = −16t^2 + 15 gives the height h of the ball (in feet) after t seconds. Graph the function. Then determine the approximate time the ball hits the ground.
The ball will hit the ground at 0.968 seconds.
Step-by-step explanation:
Please refer to the attached graph in the answer area.
The given equation of height according to input variable time 't' is:
h is in feet
t is in seconds
Both the values 't' and 'h' will be positive. (Time and height can never be negative)
To determine the time, at which the ball hits the ground, i.e. the height becomes 0.
Putting value of h = 0 in equation (1)
Hence, the time at which the ball hits the ground is 0.968 seconds.
the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.
step-by-step explanation:
ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!
simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).
the gcf of 48 and 16 is 16.
divide both terms by 16:
48 ÷ 16 = 3
16 ÷ 16 = 1
reducing to simplest form:
48 : 16 = 3 : 1
