expeople1 [14]

Answer:

y = 1/3a

Step-by-step explanation:

y = ka

1 = 3k

k = 1/3

Confirm constant: (4-1)/(12-3) = 3/9 = 1/3

1 = 3(1/3) + b

1 = 1 + b

b = 0

y = 1/3x or 1/3a

A watermelon is launched from a 25-foot tall platform at a carnival. The watermelon's height h (in feet) at time t seconds can b
Nataly [62]

Answer:

The maximum height of the watermelon is 74 feet.

Step-by-step explanation:

The watermelon reaches its maximum height when its velocity is zero. Mathematically speaking, velocity is the first derivative of the function height, that is:

v(t) = \frac{d}{dt} h(t) (1)

Where v(t) is the velocity, in feet per second.

If we know that h(t) = -16\cdot t^{2}+56\cdot t +25 and v(t) = 0\,\frac{ft}{s}, then the time associated with maximum height is:

v(t) = -32\cdot t +56 (2)

-32\cdot t + 56 = 0

t = 1.75\,s

Now we evaluate the function height at time found in the previous step: (t = 1.75\,s)

h(t) = -16\cdot t^{2}+56\cdot t +25

h(1.75) = 74\,ft

The maximum height of the watermelon is 74 feet.
