Answer:
Between 3 and 4
Step-by-step explanation:
3^2 = 3 × 3 = 9
4^2 = 4 × 4 = 16
12 is between 9 and 16
W=IH/V that is the final answer
Answer:600 x X
Step-by-step explanation:
The numerical solution to this question requires knowledge of the fuel consumption of the vehicle. However assuming that the vehicle consumes X gallon of gasoline per mile, the cost in gasoline to drive 600 miles would be 600 x X =600X
Answer: x=2
57+x=25x
subtract x from both sides
57+x-x=25x-x
57=24x
divide by 24 on both sides
57÷24=24x÷24
x=2.375
I hope this is good enough:
Answer:
a) 
b) 
Step-by-step explanation:
Part a
Since the buoy oscillates in simple harmonic motion the equation to model this is given by:
For this case from the info given we know that:
"It returns to its high point every 10 seconds." That means period =10 
, and the angular frequency can be founded like this:
Assuming that the value for the phase is 
our model equation is given by:
Part b
From definition we can obtain the velocity with the derivate of the position function and if w calculate the derivate we got this:
