2. 1. 3. 3 6 . b. Classify the system, and tell how many solutions it has. 6. ... She spent the entire amount on songs, ... number of music videos Mariana bought. 7. A chemist needs to mix a 2% acid solution and a ... sandwich spread. ... Use the given matrices for Items 13–20. A ... person sold and the amount of money collected.
Step-by-step explanation:
For this case we have the following function:
The first thing you should do is graph the function to see the behavior.
When observing the graph (in the attached image) we observe that the following point belongs to the graph:
To prove it, let's evaluate the point in the function:
The equation is fulfilled and therefore the point belongs to the graph.
Answer:
(6.2, 7.4)
See attached image
The distance is given by
y = 58t - 1.86t²
The velocity is the derivative of y with respect to t. It is
v = 58 - 3.72t
In an interval [t₁, t₂], the average velocity is
Evaluate the results (Use v to denote the average velocity).
i. t = [1,2]
v = (108.56 - 56.14)/1 = 52.42
Answer: 52.42 m/s
ii. t=[1,1.5]
v = (82.815 - 56.14)/0.5 = 53.35
Answer: 53.35 m/s
iii. t=[1,1.1]
v = (61.5494 - 56.14)/0.1 = 54.094
Answer: 54.094 m/s
iv. t=[1,1.01]
v = (56.6826 - 56.14)/0.01 = 54.26
Answer: 54.26 m/s
Note:
As the time interval approaches zero, we obtain the derivative of y at t=1, which is 58-3.72 = 54.28 m/s
