Answer:
First box -3, 1
Second box -3, 7
Step-by-step explanation:
If they start at 4 on the y-axis, they can go down to 1 or go up to 7. Then we just add the -3 to the x axis.
There are 60 min per hour.
There are 24 hours in one day, so there are 60 times 24= 1,440 minutes in a day.
Person A: for 45 minutes per day had a heart rate of 150, and for 1,395 minutes per day had a heart rate of 60.
This means that her heart rate totaled (45x150) + (1,395x60) = 90,450 beats per day.
Person B: for 1,440 minutes per day had a heart rate of 72 beats per minute.
This means that her heart rate totaled (1,440x72) = 103,680 beats per day.
So for 365 days: 365(103,680-90,450)= 4,828,950-this is the number of beats MORE per year of Person B than Person A.
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
2 to the 9th power 512. Hopes this helps!
Answer:
C
Step-by-step explanation:
From the graph you can see that y changes from -2 to 2, so the range of the function is ![[-2,2].](https://tex.z-dn.net/?f=%5B-2%2C2%5D.)
Since the range of the functions 
and 
is ![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
and the range of the functions 
and 
is ![[-k,k],](https://tex.z-dn.net/?f=%5B-k%2Ck%5D%2C)
we can state that the correct option is C:
