Answer: 
Step-by-step explanation:
Let u be a differentiable function , then
(1)
Given function : 
Differentiate both sides with respect to x , we get
(By using (1))
[∵ 
]
Hence, the derivative of the given function is .
One way distance is 150x-100
so for roundtrip it is 2(150x-100)
Answer:
25
Step-by-step explanation:
Let x be the number of students in the class
15 is 60% of x
60% of x can be written as 0.6x
15 = 0.6x
Divide by 0.6 on both sides
25 = x
There are 25 students in the class
Hope this helps :)
Angle OSP and angle QSR are congruent because angles that are complementary to the same angle are congruent.
