Answer:
Step-by-step explanation:
ohn will need to sleep for 10.3 hours before his second exam so that the
he average of his two exam scores is an 80.
We were given
8 hours of sleep = 70
To get an average of 80
70+ x = 80
2
Cross multiply:
70+x = 160
x= 160-70
= 90.
If 8 hours of sleep = 70
x hours of sleep = 90
Cross multiply
8× 90 = 70 × x
720 = 70x
x = 720/70
x = 10.2857
≈ 10.3 hours of sleep
Per the plot, looks like g(-8) = 1 and g(2) = -4. Then the average rate of change of g over [-8, 2] is
(g(2) - g(-8)) / (2 - (-8)) = (-3 - 1)/10 = -2/5
If the smaller volume ratio is 4 to 1331, divide 1331 by 4 to get the multiplying factor.
1331/4 = 332.75
Now we multiply 332.75 by 7 to get our larger volume.
332.75 x 7 = 2329.25
2,329 is our larger volume.
I hope this helps!
The answer is the 3rd option, y>2/3x+3
This is because first of all, the slope is 2/3x I figured out it was 2/3 because I picked two points, (0,3) and (-3,1). Then I found slope which was 2/3x. I looked at the graph, and the y-int was 3 so good so far. Then I put y is GREATER because it’s shading above the line!!!
