Answer:
a(t) = 700t-400
Step-by-step explanation:
Given that when Nour drove altitude increased at a constant rate. Let us consider sea level as 0 and starting time as 0 we have
At the start t =0 and a = -400 m
When t=2 a = 1000 m.
Rate of change of a wrt time = change in a/Change in time
= {1000-(-400)}/(2-0) = 700
i.e. slope = 700
a = 700 t +C
To find C:
When t =0, a =-400
Hence C =-400
Equation is a(t) = 700t-400
Answer:
A
Step-by-step explanation:
Using the pythagorean theorem,
we plug the numbers in;
9+36=c^2
45=c^2
sqr root of 45 is
next find the positive perfect sqr root of 45 which will be 9.
9 goes into 45 5 times so it will be
Sqr root of 9 is 3 so it will be
