The other practices would one 1 hour.
If he practices a total of 5 hours:
5-2=3 for mondays practice
3 ÷ 3 = 1 for the rest of the practices
Differentiating both sides of
with respect to 
yields
At the point (3, 4) (so 
and 
), the tangent line has slope
Then the tangent line to (3, 4) has equation
Answer: C) 1560
Step-by-step explanation:
So the first part is splitting the rectangle from the triangle so the area for the rectangle is 1440 (40 x 36) and the area for the triangle is 120 ((6x40)/ 2)
when you add them up the equal 1560 (1440 + 120)
Let x be her initial distance from the building, then tan 37 = 130/x
x = 130/tan 37 = 130/0.7536 = 172.5 feet
Let y be her distance from the building after moving forward, then
tan 40 = 130/y
y = 130/tan 40 = 130/0.8391 = 154.9
After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
