Answer:
Price of 1 child ticket is $5.4
Price of 1 adult ticket is $10.8
Step-by-step explanation:
Given:-
6 children and 2 adults are going for circus.
Children ticket is half the price of adult ticket.
Total ticketing cost =$54
To find:-
Cost of 1 child ticket=?
Cost of 1 Adult ticket=?
Solution:-
Let price of 1 child ticket be x and price of 1 adult ticket be y,
therefore from the given data we get 2 equations,
-----------------------------------(1)
--------------------------------(2)
Now, substituting the value of x from equation 2 in equation 1,
------------------------(3)
Now, substituting the value of y from equation 3 in equation 2,
------------(from equation 3)
----------------------(4)
As, x is price of 1 child ticket and y is price of 1 adult ticket,
Therefore price of 1 child ticket is $5.4 and price of 1 adult ticket is $10.8
Answer:
3, in both a), b)
Step-by-step explanation:
a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.
Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is . In particular, the value we are looking for is
.
If you would like to compute the equation of the tangent line, we can use the point-slope equation to get
b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to .
