the answer to this question is -7.25 or 7 1/4
Answer:
C
Step-by-step explanation:
Given the tables of H(t) an r(t), we want to find:
As stated, this is equivalent to:
Using the r(t) table, we can determine that:
Therefore:
And by using the H(t) table, we can determine that:
So, our answer is C.
Find the velocity first, the "slope".
m=(y2-y1)/(x2-x1)
m=(95.5-53)/(4-2)
m=21.25 ? Your equations are wrong, I'll double check with another set of points...
m=(350.5-308)/(16-14)
m=21.25 LOL, yep none of your lines has the correct slope.
Anyway...
y=21.25x+b, using any point we can solve for the y-intercept, or "b", (2, 53)
53=21.25(2)+b
53=42.5+b
10.5=b so the distance to the lighthouse as a function of time is:
y=21.25x+10.5
So essentially, you should fire your teacher or burn that book you are using :)
