Punxsutawney phil was sleep-walking last night. he managed to wander out into the middle of the road, when a car came into sight. the function d=0.037v² represents the relationship between the velocity of the car and the distance needed to stop the car (d= distance in feet and v= velocity in mph)

1. what distance does the car need to come to a complete stop if it’s traveling at 60 mph

2. if phil is 100 feet away when the driver hits the brake, will phil be roadkill?

what is the answer to this

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)

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450
