Answer:
The second graph is correct, that the line intersects x at 6 and y at 11.5
Step-by-step explanation:
Samuel has to sell at least $90 for his concert. According to the graph, if Samuel sells only child ticket, he will have to sell 11.5 tickets.
If Samuel sells only adult tickets, he will have to sell at least 6.
The correct graph is the second one, that the line intersects x at 6 and y at 11.5
Y= x^2-58
X^2-58=0
X^2=58
X= sqrt of 58
X= 7.6
Y= x^2+13
X^2+13=0
X^2=-13
Get sq rt of 13 the negative becomes i
X= 3.6i
The correct answer is -1 and 1/2.
First, you need to divide 1/2 by -4/5. To do this, you multiply 1/2 by -5/4. You will get -10/8.
Then, you add -10/8 with -2/8 to get -12/8, or -1 and 1/2.
Answer:
The maximum fuel economy of the car is 25.57225
Step-by-step explanation:
we are given
where
where s represents the average speed of the car, measured in miles per hour
So, we have to maximize f(s)
So, firstly we will find derivative
now, we can set it to 0
and then we can solve for s
To find maximum fuel economy , we can plug s into f(s)
So,
The maximum fuel economy of the car is 25.57225
