You will need 28 vans. 3 students will ride in the van that isn't full.
Answer:
(1,-3) and (-2,0)
Step-by-step explanation:


Applying the second equation to the first

Solving the equation we get

When x = 1

When x = -2

So, the line and curve will intersect at points (1,-3) and (-2,0)
Answer:
2187
Step-by-step explanation:
This is the same as 3^7, which is 2187
472 to the nearest 100 is 500
For this case we have the following difference equation:

Applying separable variables we have:

Integrating both sides we have:

applying exponential to both sides:

For y (1) = 1 we have:

Thus, the particular solution is:

Whose domain is all real.
Answer: y = 0.2 * exp ((3/2) x ^ 2) Domain: all real numbers
