Answer:
A
Step-by-step explanation:
Answer: x=0
Step-by-step explanation: f(x)=(x+2)x2-4
0=2x+4-4
0=2x
2x/2=0
0/2=0
x=0
Answer:
Step-by-step explanation:
start by gathering all the x together.
6x-3x-2x=1x
what you have left is 1x+4=?x+?
Q.34

The infinite geometric series is converges if |r| < 1.
We have r =1.002 > 1, therefore our infinite geometric series is Diverges
Answer: c. Diverges, sum not exist.
Q.35

The infinite geometric series is converges if |r| < 1.
We have r = 4/5 < 1, therefore our infinite geometric series is converges.
The sum S of an infinite geometric series with |r| < 1 is given by the formula :

We have:

substitute:

Answer: c. Converges, -25.
Answer:
Option a.
Step-by-step explanation:
By looking at the options, we can assume that the function y(x) is something like:


such that, y(0) = √4 = 2, as expected.
Now, we want to have:

replacing y' and y we get:

Now we can try to solve this for "a".

If we multiply both sides by y(x), we get:


We can remove the x factor in both numerators if we divide both sides by x, so we get:

Now we just need to isolate "a"


Now we can subtract a*x^2 in both sides to get:

Then the solution is:

The correct option is option a.
