The graph of the function is missing and so i have attached it alongside the options.
Answer:
B & C are correct.
Step-by-step explanation:
From the attached graph, we can see that at interval 2, the line is falling down and not rising.
This means that the function is decreasing because y is decreasing while x is increasing.
Also, when both x and y are increasing, the slope is positive but when one is increasing and the other is decreasing like we have here, it means the slope is negative.
Thus, the function is decreasing and the slope is negative.
Since a sphere's surface area is 4πr², we then need to find r as a function of time t, which is 9t (since it increases by 9 every second)+0 (the initial value)=9t. Plugging it in, we get 4π(9t)²=4π*36t²=144πt²
Answer:
Width is 11 inches
Step-by-step explanation:
I am not sure what the question is. I think you might be looking for the width length. The perimeter is the distance around a rectangle. If the whole distance around is 48. We have 2 lengths and 2 widths. They tell us that the length is 13. We have two lengths so the lengths add up to 26. We can subtract that from 48 and that leaves us with 22 (48-26) This is the total for the 2 widths. Since the 2 widths are the same length we divide that number by 2 to get 11.
11 + 11+ 13 + 13 = 48
We know form our problem that the third day she biked 20 miles, so we have the point (3,20). We also know that <span>on the eighth day she biked 35 miles, so our second point is (8,35).
To relate our two point we are going to use the slope formula: </span>
We can infer form our points that
,
,
, and
. so lets replace those values in our slope formula:
Now that we have the slope, we can use the point-slope formula <span>determine the equation of the line that best fit the set for Maggie’s data.
Point-slope formula: </span>
We can conclude that the equation of the line that best fit the set for Maggie’s data is
.
