Let N be the number to find
firstly: 66 2/3 = 200/3 = 66.6666 & in % it's = 0.66666
secondly N x 0.6666= 90 then N = 90/0.6666 =135
Answer:
2x=26x
It is not correct mathematically!
Step-by-step explanation:
Simplify the braces
2x+12=12+26x
You have 12 on both sides so you can simply remove it.
The result: 2x=26x
Answer:
12 and -2
Step-by-step explanation:
Can you show the entire graph provided? It is needed to solve the problem.
To get the average resting position of the spring, we must subtract the minimum from the maximum height of the spring with respect to the floor.
So,
7 + (4/12) - [ 6 + (2/12) ] = 1.5 ft
Half of this is where the resting position of the spring is located with respect to the minimum height. If the resting position of the spring is set at 0, then the amplitude of the wave is:
A = 1.5 / 2 = 0.75
Since it takes 2 seconds for the spring to expand from minimum to maximum,
Period = 2 = 2π / n
n = π
The cosine function is:
y = A cos nt
where y is the distance from the resting position and t is the time in seconds.
y = 0.75 cos πt
