Answer:
(-2, 4)
Step-by-step explanation:
When you reflect a point over y=1, the location of the new y coordinate must have the same distance away to y=1 as the previous point. (In this case, (1 - - 2) = 3, and 4 - 1 = 3)
The height of the kite is 4.89 feet
Explanation
The length of the line attached to the kite=7 feet
The length of the shadow that is cast on the ground=5 feet
the system forms a right angled triangle where the taught string of the kite is the hypotenuse, the shadow is the base and the height of the kite above the ground is the height.
H=7 feet
b=5 feet
using pythagoras theorem

The kite is 4.89 feet above the ground
t=45min
d=4km
45min/60min = 0.75 hours
v=d/t
v=4km/0.75hours
v=5.33km/hour. So the answer is B. 45 minutes.
If 14 out of 20 is correct, then that is : 14/20 = 0.70 = 70%
In order to answer this we need the table, however to do this all you would do would be to multiply the p value in the table with the corresponding r value in the table and then multiply this by 5, then order them, smallest to greatest.
