Hey there!
ASSUMING
2/5 * 5/9
CONVERTING #1
= 2(5) / 5(9)
= 10/45
CONVERTING #2
= 10 ÷ 5 / 45 ÷ 5
= 2 / 9
MET THE ANSWER
= 2/9
Therefore, the answer should be: 2/9
Good luck on your assignment & enjoy your day!

Answer:
Step-by-step explanation:
A force of 5 pounds stretches a spring 1 foot.
This implies that, the string constant (K) = 5 lbs? ft
Mass (m) =
=
The damping force
The negativity of the damping force is due to the fact that it opposes the motion.
Then the force due to the spring is :
where;
x = the mass distance from the equilibrium point.
Total Force F =
⇒ F = -1.2v - 5.0 x
⇒ mx = -1.2v - 5.0 x
where v = x' and a = x"
Hence, the equation becomes mx" = -1.2x' - 5.0 x
⇒ = 0
⇒
The auxiliary equation is can be written as:
⇒ r =
r =
r = OR
Now,the general equation of motion is :
Initial Conditions are:
x(0) = -1 and x' (0) = 0
x(0) = -1
⇒ -1 =
x' (0) =0 ⇒ 0 = -3(-1) + (4)
⇒ =
Thus:
Answer:
Step-by-step explanation:
Let the number of car be c
Let m be the amount raised
If after 11 cars, they raised a total of $93.50, this means
at c1 = 11, m1 = $93.50
If after 23 cars, they raised a total of $195.50, this means:
at c2 = 23, m2 = $195.50
Get the proportionality constant
k = 195.50 - 93.50/23-11
k = 102/12
k = 8.5
Since m = kc
Substitute k = 8.5 into the equation:
m = 8.5c
Hence the equation that represents the equation is m = 8.5c
