Step-by-step explanation:
Explanation:
Because
(2,6) is in the function, we can plug
6 as y
and
2 as x.
From that we get
6=a(2−1)2+k
6=a+k
Same for the next point:
12=a(3−1)2+k
12=22a+k
12=4a+k
Now we have this system of equations to solve:
a+k=6
4a+k=12
Solving it leads to the conclusion that
a=2,k=4 .
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

It will take Eli 2.4 minutes to complete 6 laps
Step-by-step explanation:
Given
Speed = s = 1000 meters per minute
Length of one lap = 400 meters
We have to compute time for 6 laps,, so we have to find the length of 6 laps combined
So our total distance will be: 2400 meters
using the formula for speed
So
It will take Eli 2.4 minutes to complete 6 laps
