Joseph jumped off of a cliff into the ocean in Miami while vacationing with some friends. His height as a function of time is gi
Aneli [31]

Answer:

Step-by-step explanation:

I think the missing equation in your question is: h(t) = -16 t^{2} + 16t + 480

Here is my answer:

As we know that the vertex form of a parabola, y=a(x-h)^{2} + k where(h,k) is the vertex

h(t) = -16 t^{2} + 16t + 480

= -16 (t^{2} -t) + 480  

= -16 (t-\frac{1}{2}) ^{2} + 484

So the vertex is (\frac{1}{2} , 484)

a. It take for Joseph \frac{1}{2} second to reach his maximum height

b. The highest point that Joseph reached is the vertex of the function, it is 484 ft

c. Joseph hit the water after how many seconds?

<=> h(t) = 0

<=>  -16 t^{2} + 16t + 480  = 0

<=> t = \frac{192}{32} second = 6 sec

Hope it will find you well

Function g is defined below.
Elina [12.6K]
Rule: if you have graph of function y=f(x) and a>0, then:
1. y=f(x-a) is translation a units right;
2. y=f(x+a) is translation a units left;
3. y=f(x)-a is translation a units down;
4. y=f(x)+a is translation a units up;

Since g(x)=f(x+2)-5, then firstly you have to translate the graph of function y=f(x) two units left and secondly 5 units down.
