Answer:
12,600mg per 21 days
Step-by-step explanation:
200mg three times a day → (200mg)(3) = 600mg per a day
21 days → (21)(600mg) = 12,600mg per 21 days
Answer:
the youngest brother is of 2 years and 5 months
if this rule still applies, the next son will be born in 2 months.
Step-by-step explanation:
Given that:
Oldest son= 11 3/4 years old = 11 years 3/4 (12) months = 11 years 9 months
Difference = 2 years 7/12(12) months = 2 years 7 moths
So for finding the age of youngest brother:
Subtract the difference others from age of oldest:
= 11 years 9 months - 4(2 years 7 months)
= 11 years 9 months - 9 years 4 months
= 2 years 5 months
So the youngest brother is of 2 years and 5 months
if this rule still applies, the next son will be born in 2 months.
i hope it will help you!
Answer:
y2 = C1xe^(4x)
Step-by-step explanation:
Given that y1 = e^(4x) is a solution to the differential equation
y'' - 8y' + 16y = 0
We want to find the second solution y2 of the equation using the method of reduction of order.
Let
y2 = uy1
Because y2 is a solution to the differential equation, it satisfies
y2'' - 8y2' + 16y2 = 0
y2 = ue^(4x)
y2' = u'e^(4x) + 4ue^(4x)
y2'' = u''e^(4x) + 4u'e^(4x) + 4u'e^(4x) + 16ue^(4x)
= u''e^(4x) + 8u'e^(4x) + 16ue^(4x)
Using these,
y2'' - 8y2' + 16y2 =
[u''e^(4x) + 8u'e^(4x) + 16ue^(4x)] - 8[u'e^(4x) + 4ue^(4x)] + 16ue^(4x) = 0
u''e^(4x) = 0
Let w = u', then w' = u''
w'e^(4x) = 0
w' = 0
Integrating this, we have
w = C1
But w = u'
u' = C1
Integrating again, we have
u = C1x
But y2 = ue^(4x)
y2 = C1xe^(4x)
And this is the second solution
The given measurements determine one triangles, A = 61Á, a =
23, b = 24 because the triangle can be defined using those 3 data, first is
using the sine law to solve another angle. Then using cosine law to solve the
third side. Lastly solving the 3rd angle by difference.
The length of the circle - <span>the product of the diameter and the number Pi
