Answer:
Scale factor is used to find the coordinates depending upon whether the scale factor value is less than one or more than one.
Step-by-step explanation:
A scale factor is a number which scales, or increases, some amount. In the condition y = Cx, C is the scale factor for x. C is likewise the coefficient of x, and might be known as the steady of proportionality of y to x.
An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1. To discover the expanded picture, we initially should know the directions of our unique picture. At that point we basically increase the arrange by the scale factor to discover the widened picture.
Answer:
decreasing at 390 miles per hour
Step-by-step explanation:
Airplane A's distance in miles to the airport can be written as ...
a = 30 -250t . . . . . where t is in hours
Likewise, airplane B's distance to the airport can be written as ...
b = 40 -300t
The distance (d) between the airplanes can be found using the Pythagorean theorem:
d^2 = a^2 + b^2
Differentiating with respect to time, we have ...
2d·d' = 2a·a' +2b·b'
d' = (a·a' +b·b')/d
__
To find a numerical value of this, we need to find the values of its variables at t=0.
a = 30 -250·0 = 30
a' = -250
b = 40 -300·0 = 40
b' = -300
d = √(a²+b²) = √(900+1600) = 50
Then ...
d' = (30(-250) +40(-300))/50 = -19500/50 = -390
The distance between the airplanes is decreasing at 390 miles per hour.
