Answer: 2450 min or 40hr and 50 min
Step-by-step explanation:
We can use a proportion to set up this equation.

We cross muliply so get our equation.



It took Mike 2450 min to read 1225 pages. We can also use a proportion to write this in hours

First lets make these numbers more simple...
9.1 x 10^2 = 910
918% = 918 (reason being percents are out of 100, so 100 = 100%, therefore 918% = 918) (this was wrong, its actually 918 / 100 = 9.18 by conversion of percent to decimal)
1830 / 2 = 915
920.0 = 920
Your arrangement: 920 , 918 , 915 , 910
Another way is: 920.0, 918% , 1830 / 2, 9.1x102
(answer is actually 920.0, 1830 / 2, 9.1 x 10^2, 918%)
Answer:
Below.
Step-by-step explanation:
Plot following points.
Calculate the point by plugging in values of x into x^2 + 1
for example When x = 0, y = 0^1 + 1 = 1.
So plot plot (0, 1),
Make a table of points to plot:
x -3 -2 -1 0 1 2 3
y 10 5 2 1 2 5 10
When you plot the points you'll see the graph is U shaped.
The function is of second degree (as it contains x^2) so it wont be linear.
