Peter and his neighbor, Juan walk 2 miles to school each day yesterday peter walked to school in 27 minutes Juan walked the firs
a_sh-v [17]

Total distance from their home to school is 2 miles.

Peter covered this distance in 27 minutes yesterday. Since the rate of walking is the same today, Peter will arrive in school in 27 minutes today.

Juan covered 1 mile in 11 minutes yesterday. This means she will cover 2 miles in 22 minutes. Since the rate(speed) of walking of Jaun is also same as that of yesterday, Juan will reach the school in 22 minutes.

Thus, we can conclude that if Peter and Juan leave at the same time, Juan will reach the school 5 minutes earlier than Peter.

Over the closed interval [3,8] for which function can the extreme value theorem be applied?
vodka [1.7K]

The extreme value theorem can be applied on an interval if the function is continuous in the entire interval. Testing the continuity for each function, we get that the correct option is the third option.

Continuity:

A function f is continuous at an interval if all points in the interval are in the domain of the function, and, for each point of x^{\ast}, the limit exists and:

\lim_{x \rightarrow x^{\ast}} = f(x^{\ast})

First function:

At x = 4, the denominator is 0, and so, the extreme value theorem cannot be applied.

Second function:

At x = 5, the denominator is 0, and so, the extreme value theorem cannot be applied.

Third function:

The only point there can be a discontinuity is at x = 4, where the definition of the function changes. First we have to find the lateral limits, and if they are equal, the limits exist:

To the left(-), it is less than 4, so we take the definition for x < 4.

To the right(+), it is more than 4, so we take the definition for x >= 4.

\lim_{x \rightarrow 4^{-}} h(x) = \lim_{x \rightarrow 4} \frac{9x}{10-x} = \frac{9*4}{10-4} = \frac{36}{6} = 6

\lim_{x \rightarrow 4^{+}} h(x) = \lim_{x \rightarrow 4} x + 2 = 4 + 2 = 6

The lateral limits are equal, so the limit exists, and it's value is 6.

The definition at x = 4 is h(x) = x + 2, so h(4) = 4 + 2 = 6.

Since \lim_{x \rightarrow 4} = h(4), the function is continuous over the entire interval, and this is the correct answer.

Fourth function:

There can be a discontinuity at x = 5, so we test the limits:

\lim_{x \rightarrow 5^{-}} h(x) = \lim_{x \rightarrow 5} -x = -5

\lim_{x \rightarrow 5^{+}} h(x) = \lim_{x \rightarrow 5} x^2 - 20 = 5^2 - 20 = 25 - 20 = 5

Different limits, so the limit does not exist and the function is not continuous at x = 5, and the extreme value theorem cannot be applied.
