A hot-air balloon, headed due east at an average speed of 15 miles per hour at a constant altitude of 100 feet, passes over an intersection (see the figure). Find an expression for its distance d (measured in feet) from the intersection 1 seconds later.

The distance is

Step-by-step explanation:

Given that,

Altitude = 100 feet

Average speed = 15 miles/ hour

We need to calculate the speed in feet/sec

Using formula for speed

We need to calculate the distance in t sec

Using formula of speed

Put the value into the formula

According to figure,

We need to calculate the distance

Using pythagorean theorem

Put the value into the formula

Hence, The distance is

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
