Mr T roule 75km à 140 km/h avant de se faire verbaliser. Il est immobilisé 20 minutes par la gendarmerie avant de repartir. Il roule alors les 250 km restants à 125 km/h.
A quelle vitesse régulière aurait-il pu rouler pour arriver à la même heure ?

answer: $1794

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)

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
