Answer:
A dilation with a scale factor less than 1 and then a reflection.
Step-by-step explanation:
A dilation with a scale factor less than 1 and then a reflection is the composition of similarity transformations maps polygon ABCD to polygon A'B'C'D.
Step-by-step explanation:
Old Railroad Car:
- 1 day of coal in 15 hours
- 1/15 days of coal in 1 hour
New Railroad Car:
- 1 day of coal in 10 hours
- 1/10 days of coal in 1 hour
Total number of days of coal in 1 hour
= 1/15 + 1/10 = 1/6.
Since there is 1/6 days of coal in 1 hour,
there will be 1 day of coal in 6 hours.
It will take them 6 hours to transport the supply.
Answer:
The distance from the pole is 11.8 ft
Step-by-step explanation:
Let
x------> the distance from the pole
we know that
The tangent of angle of 28 degrees is equal to divide the opposite side to angle of 28 degrees ( the height of the pole) by the adjacent side to angle of 28 degrees ( the horizontal distance from the pole)
so
tan(28°)=6.3/x
Solve for x
x=6.3/tan(28°)=11.8 ft
Answer:
y = -x²+8x+16
