Each October Albuquerque, New Mexico, hosts the Balloon Fiesta. In 2003, 744 hot air balloons participated in the opening day festivities. One of these balloons rose 389 feet after 1 minute. Because the air in the balloon was not reheated, each succeeding minute, the balloon rose 63% as far as it did the previous minute. a. Use sigma notation to represent the height of the balloon above the ground after one hour. then calculate the total height of the balloon after one hour to the nearest foot.

b. What was the maximum height achieved by this balloon?

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

answer: you need the equation in the question so i can answer it

step-by-step explanation:

12

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
