B<em> (That’s the answeeerrr)</em>
Answer:
10x^2-4x
Step-by-step explanation:
We will have to open the bracket first
So let's solve
2x(5x-2)
10x^2-4x
Since we are not asked to solve further so we will have to leave he final answer as 10x^2-4x
But in the case where a certain value is given to substitute for x we will have to solve further
Answer:
0.25s
Step-by-step explanation:
As v = 1.5 cos(4πt), v is maximum when cos(4πt) is maximum = 1. So the maximum velocity would be 1.5 m/s
Both the lowest and highest position occurs when its derivative is 0, aka v = 0 and has a change of direction
1.5 cos(4πt) = 0
cos(4πt) = 0
4πt = π/2 and 4πt = 3π/2
t = 1/8 = 0.125s and t = 3/8 = 0.375s
So the time it takes to travels from 1 point of time (0.125s) to another point of time (0.375) is
The formula for slope is
Slope = Rise / Run = Risers / Treads
Slope = 7.75 in /10 in = 0.775
The slope Is 0.775.
The vertical distance is not continuous, thus it is
discrete. A discrete function only allows certain points in the interval. When
you walk up or down the stairs, the vertical distances are not continuous
because of the treads. You cannot stay also mid-air, so it should be discrete.
An example of a continuous function would be when you walk up or down an
inclined plane.
Answer:30
Step-by-step explanation: Put 30 times 15 into a calulater. Then do 15 times 2 then you find your answer.
