The function D(t) defines a traveler's distance from home, in miles, as a function of time, in hours. D(t) = StartLayout enlarge
nalin [4]

- At 2 hours, the traveler is 725 miles from home.

- At 3 hours, the distance is constant, at 880 miles. --> TRUE.

- The total distance from home after 6 hours is 1,062.5 miles --> TRUE.

Step-by-step explanation:

The function D(t) is defined as follows:

D(t) = 300t+125 for t< 2.5

D(t) = 880 for 2.5 \leq 3.5

D(t) = 75t+612.5 for t\leq 6

Where

t is the time in hours

D(t) is the distance covered, in miles, after t hours

Now let's analyze the different statements:

- The starting distance, at 0 hours, is 300 miles. --> FALSE. In fact, if we substitute t = 0 into the 1st equation, we get

D(0) = (300)(0)+125 = 125

So, the distance at t = 0 is 125 miles.

- At 2 hours, the traveler is 725 miles from home. --> TRUE. In fact, if we substitute t = 2 into the 1st equation,

D(2) = (300)(2)+125 = 725

- At 2.5 hours, the traveler is 875 miles from home. --> FALSE. In fact, for t=2.5 we have to use the 2nd equation, which states that the distance is:

D(t) = 880

So, not 875 miles.

- At 3 hours, the distance is constant, at 880 miles. --> TRUE. This is clearly visible from the 2nd equation: for t between 2.5 and 3.5 (so, in this case), the distance is

D(t) = 880

- The total distance from home after 6 hours is 1,062.5 miles --> TRUE. In fact, if we replace t = 6 into the last equation,

D(6)) = 75(6)+612.5=1062.5

A new obstacle course is home to several new types of challenging obstacles. One such obstacle is traversing a 15-stair staircas
Tresset [83]

Answer: 22\frac{1}{2}\text{ Feet}

Step-by-step explanation:

Here, the vertical space between two consecutive stairs in first 10 stairs = 1\frac{1}{3}\text{ feet}

⇒ The total vertical distance for 10 stairs = 10\times 1\frac{1}{3}=10\times \frac{4}{3}=\frac{40}{3}\text{ feet}

Also, The vertical space between two consecutive stairs for last 5 stairs = 1\frac{3}{4}\text{ feet}

⇒ The total vertical distance for 10 stairs = 10\times 1\frac{1}{3}=5\times \frac{7}{4}=\frac{35}{4}\text{ feet}

Thus, The total vertical distance = Total vertical space for the first 10 stairs + Total vertical space for the last 5 stairs

= \frac{40}{3} + \frac{35}{4}

= \frac{160+105}{12}

= \frac{265}{12}

= 22\frac{1}{2}\text{ Feet}
