Answer:
3
Step-by-step explanation:
2x+x+2+x+2+4x+1 = 4x+3x+2+2x
2x+x+x+4x + 2+2+1 = 4x+3x+2x+2
8x+ 5 = 9x + 2
5-2=9x-8x
x= 3
I hope im right!!
For the answer to the question above asking the explicit equation and domain for an arithmetic sequence with the first term of 5 and the second term of 2? I think the answer for this is <span>5-2(n-1); all integers where n≥0. I hope this helps.</span>
Answer:
The value of the damping coefficient γ is (6/19)√29, which is approximately 1.70058.
Step-by-step explanation:
Given that a certain vibrating system satisfies the equation
u'' + γu' + u = 0
We wish to find the value of the damping coefficient γ for which the quasi period of the damped motion is 90% greater than the period of the corresponding undamped motion.
The period of the undamped motion T is 2π
The quasi period T_d is (4π)/√(4 - γ²)
Since the quasi period is 90% greater than the period of the undamped motion, we have
T_d = 1.9T
So that we can finally obtain
γ as 1.70058.

Answer:
c 17000 mowers
Step-by-step explanation:
y = 5500 ln (9t+4)
y is the number of mowers sold
t is the number of years
Substitute 2 in for t to find the number of mowers sold after 2 years
y = 5500 ln (9*2+4)
= 5500 ln (18+4)
= 5500ln(22)
17000.7334934707
Round to the nearest hundread
17000
1: 3.2kg
2: 12000ml
3: 2m
4: 70kg
5: 10l
6: 60000mm
Hope this works hehe
