Answer:
two hours and thirteen minutes.
Step-by-step explanation:
count up from 3pm to 5pm to start with. That gives you two hours
we already have 38 minutes, now just subtract the 25 minutes he spent resting.
That leaves you with 2 hours and 13 minutes.
Correct me if I'm wrong I'm currently responding to this at a major lack of sleep lol
Answer:
(c) n(n+1)/√2
Step-by-step explanation:
√2+√8+√18+√32+...
1√2+2√2+3√2+4√2+...+n√2
- First term= √2
- Common difference= √2
- Sₙ= n/2(2√2+(n-1)√2)= n/2(n√2+√2)=n(n+1)√2/2= n(n+1)/√2
Option (c) is correct
The average rate of change between the interval x = 0.5 to x = 3.5 is: 5.
x = 3.5 represents 3.5 hours after noon.
<h3>How to Find Average Rate of Change Over an Interval</h3>
Given an interval of x = a to x = b, the average rate of change over the given interval of a function can be calculated using the formula below:
![\frac{f(b) - f(a)}{b - a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29%20-%20f%28a%29%7D%7Bb%20-%20a%7D)
Given table representing the function as shown in the image attached below, let's determine the average rate of change for x = 0.5 to x = 3.5.
a = 0.5
f(a) = 47 (from the table, when x = 0.5, y = 47)
b = 3.5
f(b) = 62 (from the table, when x = 3.5, y = 62)
Plug the values into ![\frac{f(b) - f(a)}{b - a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29%20-%20f%28a%29%7D%7Bb%20-%20a%7D)
Average rate of change = ![\frac{62 - 47}{3.5 - 0.5} = \frac{15}{3} = 5](https://tex.z-dn.net/?f=%5Cfrac%7B62%20-%2047%7D%7B3.5%20-%200.5%7D%20%3D%20%5Cfrac%7B15%7D%7B3%7D%20%3D%205)
Average rate of change = 5
x = 3.5 represents 3.5 hours after noon.

Answer:
(c) 31.2-60
Step-by-step explanation:
Given that
60 – 31.2 + ? = 0
![\Rightarrow ?=31.2-60](https://tex.z-dn.net/?f=%5CRightarrow%20%3F%3D31.2-60)
This is the same as the expression in option (c) 31.2-60.
Hence, option (c) is correct.
