Use L’Hospital’s Rule to evaluate the following limit.
Serga [27]

Answer:

3

Step-by-step explanation:

lim(t→∞) [t ln(1 + 3/t) ]

If we evaluate the limit, we get:

∞ ln(1 + 3/∞)

∞ ln(1 + 0)

∞ 0

This is undetermined.  To apply L'Hopital's rule, we need to rewrite this so the limit evaluates to ∞/∞ or 0/0.

lim(t→∞) [t ln(1 + 3/t) ]

lim(t→∞) [ln(1 + 3/t) / (1/t)]

This evaluates to 0/0.  We can simplify a little with u substitution:

lim(u→0) [ln(1 + 3u) / u]

Applying L'Hopital's rule:

lim(u→0) [1/(1 + 3u) × 3 / 1]

lim(u→0) [3 / (1 + 3u)]

3 / (1 + 0)

What is the range of the function f(x)= 2 + 4 when the domain is {-2, 0, 3}?
Orlov [11]

The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]

The range are the possible output values of f(x)

We need to solve f(x) = 3.2x for each value in our domain

f(-4) = 3.2(-4) = -12.8

f(-2) = 3.2(-2) = -6.4

f(0) = 3.2(0) = 0

f(2) = 3.2(2) = 6.4

f(4) = 3.2(4) = 12.8

TIME REMAINING
Sergeu [11.5K]

Answer:

the first one.

Step-by-step explanation:

DJ and decorations are one time flat costs. they are constant. so, together, they are $300.

that is what decreases the profit.

on the other side, $5 per student = 5n in total increases our profit.

so, in total the sum of both (the decreasing amount has a negative sign, if course) :

5n - 300 = 1,500

is the right equation to calculate how many students are needed to make that much profit.

the solution, but the way :

5n - 300 = 1500

5n = 1800

n = 1800/5 = 360 students
