Answer:
INF for first while D for second
Step-by-step explanation:
Ok I think I read that integral with lower limit 1 and upper limit infinity
where the integrand is ln(x)*x^2
integrate(ln(x)*x^2)
=x^3/3 *ln(x)- integrate(x^3/3 *1/x)
Let's simplify
=x^3/3 *ln(x)-integrate(x^2/3)
=x^3/3*ln(x)-1/3*x^3/3
=x^3/3* ln(x)-x^3/9+C
Now apply the limits of integration where z goes to infinity
[z^3/3*ln(z)-z^3/9]-[1^3/3*ln(1)-1^3/9]
[z^3/3*ln(z)-z^3/9]- (1/9)
focuse on the part involving z... for now
z^3/9[ 3ln(z)-1]
Both parts are getting positive large for positive large values of z
So the integral diverges to infinity (INF)
By the integral test... the sum also diverges (D)
Answer:
It is the first one and for number 2 is 160 people total
2x=80
4x=160
Answer:
21/2
Step-by-step explanation:
The answer can be determined by substracting the lengrh of the woodland trail from the Marsh trail
- 
converting the fraction to its simplest form gives 21/2
So the angles combined should be 360 and we already know h is 90 degrees. so the rest should equal 270. Just set up an equation of:
9x + 14x + 4x = 270
then solve for x, first combine like terms
27x = 270
then get x alone by dividing
x = 10
then plug 10 into the problem next to angle f: 14x
14 * 10 = 140
