Answer:
k=-1
Step-by-step explanation:
-2=k. 2
Diving whole equation by 2
-2/2=k
k=-1
1) 2m/s = 2*18/5 =7.2Km/h
2)In 3 hour, he would travel, 7.2*3 = 21.6Km.
The answer to your question is 4/5
Answer:
Step-by-step explanation:
1) The Fundamental Theorem of Calculus in its first part, shows us a reciprocal relationship between Derivatives and Integration
2) In this case, we'll need to find the derivative applying the chain rule. As it follows:
3) To test it, just integrate:
Answer:
The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches
