Answer:
f(t) = 4 - 3t + 2t^2
Step-by-step explanation:
Given:
f(t) = a + bt + ct^2
Differentiate w.r.t. "t"
f'(t) = b + 2ct
1) f(1) = 3
a + b +c = 3...........1)
2) f(2) = 6
a + 2b + 4c = 6.........2)
3) f'(1) = 1
b + 2c = 1 ...............3)
Solving above three simultaneous equations:
a = 4
b = -3
c = 2
Therefore equation becomes:
f(t) = 4 + (-3)t + (2)t^2
Answer:
No, there is not a significant difference
Step-by-step explanation:
The sample mean (1.3) is less than the sample standard deviation (1.9). The sample mean would have to be greater than 1.9 for there to be a significant difference
The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.
From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x
We can further deduce that
tan(Θ) =

sec(Θ) =

=

cosec(Θ) =

=

cot(Θ) =

3 and a half hours i assume. so, 60 times 3 is 180, then divide by 2 to get your half, which is 30 now add that to 180. You have 210. She will travel 210 miles in 3 and a half hours. :)
8x - 7y - (3 - 6y) =
8x - 7y - 3 + 6y =
8x - y - 3
