An airplane travels about 1500 km in a straight line between Toronto and Winnipeg. However, the plane must climb
to 10 000 m during the first 200 km. Then
it must descend 10 000 m during the final
300 km.
question:
The airplane averages a speed of
600 km/h. Do climbing and descending
10 000 m add hours, minutes, or
seconds to the flight?
Please explain :)

the answer

b. they are parallel and will never intersect.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
