Answer: $247.50
Step-by-step explanation:
10 * 50 = 500
500 + 400 + 2100 = 3000
8.25/100 = 0.0825
3000 * 0.0825 = 247.5
Answer:
43.17 ft/s
Step-by-step explanation:
Let the height of the wall is y.
distance of wall from light is 20 feet.
y = 20 tanθ .... (1)
time period, T = 3 second

Differentiate equation (1) with respect to t.


dy/dt = 20 x 2.16
dy/dt = 43.17 ft/s
After a reflection across line y=x the vertices of triangle P’Q’R’ are as follows
P’= (-1,-7)
Q’= (-8-7)
R’= (-3,3)
