Multiplying both sides by gives
so that substituting and hence gives the linear ODE,
Now multiply both sides by to get
so that the left side condenses into the derivative of a product.
Integrate both sides, then solve for , then for :
Answer:
30 feet
Step-by-step explanation:
each yard is 3 feet 3x10=30
I could be wrong, but I would say it's 18.325
Answer:
Step-by-step explanation:
Given:
To make the subject of the formula means that we want to make to stand alone , the first thing to do is to multiply through by 1/4a , that is
take the square of both sides:
Answer:
18
Step-by-step explanation:
<em>First, use the equation for geometric mean; an=a1r^n-1</em>
*where is an is the number at an n term, r is the ratio and a1 is the first number of the sequence.*
12 = a1 r^5
27 = a1r^7
From the equations above,
a1 = 128/81
r = 3/2
Therefore, the 7th term is:
an = (128/81) (3/2)^6
an = 18
hope this helps :)
