To qualify for the Interlochen 470 auto race, each driver must complete two laps of the track at an average speed of 100 mi/h. Benjamin averages only 75 mi/h on his first lap. How
fast must he go on the second lap to qualify for the race?
4. Solve the equation 24 or

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

.19875994384

step-by-step explanation:

1699/ 8548

to complete this square you have to rotate about the origin 270 degrees clockwise.

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)
