Answer:
Step-by-step explanation:
Every week is just 10 more miles
Use the formula 
for quadratic trinomial. Then you can form from a quadratic trinomial perfect square:
.
From the last given step you have that
.
Since 5·16=80, you can substitute the previous expression for perfect square into function expression and get:
.
This means, when x=-4, f(-4)=-80 and vertex has coordinates (-4,-80).
Answer: correct choice is C.
Sub in 4 as x
3(4) - 29
= -17
The position equatioin is: s(t) = –16t2<span> + </span>v0t<span> + </span>h0<span>, where </span>v<span>0 </span> represents the initial velocity of the object and h0<span> represents the initial height of the object </span>. So, since the position function represents the height of an object in t seconds, s(t)= h(t). Therefor, v0= intial velocity= 60t. Double 60t and then replace that answer with 60t from Justin's rocket's equation in order to find Pedro's rocket's equation.
