Reza and James have started exercising together. When they started, Reza weighed 185 pounds and James weighed 180. After 10 week
olganol [36]
Inequality:
Let
x = pound/week weight loss by Reza
y = pounds/week weight loss by James

Therefore, after 10 weeks the two will weigh as follows:
Reza = 185 - 10x
James = 180 - 10y

But, Reza is said to be weighing less than James after 10 weeks. Then, the  inequality will be as follows:
185 - 10x < 180 - 10y

Determination of the constraints:
Solving the inequality written above;
185 - 10x < 180 - 10y
185 - 180 < 10x - 10y
5 < 10(x-y)
0.5 < x - y

Therefore,
0.5 + y < x or x > 0.5 + y

It can be seen that, for Reza to weigh less than James after 10 week, the loss of weight by Reza must be more than half to the rate of weight loss by James.

Determine whether the given limit leads to a determinate or indeterminate form. HINT [See Example 2.]
Musya8 [376]

Answer:

The limit leads to a determinate form.

\lim_{x \to \infty} \frac{2}{-x+3} = 0

Step-by-step explanation:

The following are indeterminate forms.

\frac{0}{0} \ and \ \frac{\infty}{\infty}

Given the limit of a function \lim_{x \to \infty} \frac{2}{-x+3}, to show if the given limit is determinate or indeterminate form, we will need to substitute the value of -\infty into the function as shown,

\lim_{x \to \infty} \frac{2}{-x+3}\\= \frac{2}{-(-\infty)+3}\\= \frac{2}{\infty+3}\\=  \frac{2}{\infty}\\\\Generally, \ \frac{a}{\infty} =0

where a is any constant, therefore \frac{2}{\infty} = 0

Since we are able to get a finite value i.e 0, this shows that the limit does exist and leads to a determinate form
