Answer: The scale factor of a dilation is the factor by which each linear measure of the figure (for example, a side length) is multiplied.
Step-by-step explanation:
A dilation can be described in coordinate notation as (x,y)→(2x,2y)
This is the answer just open it.
Answer: A
Step-by-step explanation: Alright so- it says that Justin is both in half of his friends photos (which would be 15 photos) and half of his family's photos (6 photos). The total amount of photos period is 50 photos and 15 is greater than 6. Therefore I would say A.
Answer:
44
Step-by-step explanation:
A=a+b
2h=6+5
2·8=44
Let α represent the acute angle between the horizontal and the straight line from the plane to the station. If the 4-mile measure is the straight-line distance from the plane to the station, then
sin(α) = 3/4
and
cos(α) = √(1 - (3/4)²) = (√7)/4
The distance from the station to the plane is increasing at a rate that is the plane's speed multiplied by the cosine of the angle α. Hence the plane–station distance is increasing at the rate of
(440 mph)×(√7)/4 ≈ 291 mph
