The answer would be (5,3)
Answer:
There's 3 total decimal places in both numbers.
Ignore the decimal places and complete the multiplication as if operating on two integers.
1 9
× 2
+ 3 8
= 3 8 Rewrite the product with 3 total decimal places.
Answer = 0.038
Therefore:
0.19 × 0.2 = 0.038
Step-by-step explanation:
The graph represents the line x = 3.
Since there is more than one y-value for the one x-value provided, this graph is not a function.
The range is infinite, as there are no limits shown on the graph, and the slope is undefined.
The domain is only 3, since the only x-value on the graph is 3.
Based on this information, the statements that are true will be:
C. This graph is not a function because the value x = 3 is assigned to more than one y-value.
E. The equation of this line is x = 3.
(Note that D says the graph <em>is a function</em>. The graph isn't a function, as there is more than one y-value for x = 3.)

Answer: Period = 90 seconds</h3>
The period represents how long it takes go from one max to the next max (ie peak to peak). It also represents going from min to min.
======================================================
Explanation:
It reaches the max at 10 seconds, and then it reaches the min at 55 seconds. This is a timespan of 55-10 = 45 seconds. This is exactly half the period. It doubles to 2*45 = 90 seconds. This is the time period between any two points in time when you're at the max height (from one max to the next adjacent max).
So you're at the max height at 10 seconds, then min at 55 seconds, then the max again at 100 seconds. Note how 100-10 = 90.
The period of any trig function is basically telling us when the function or cycle repeats itself. Once we reach the peak again, the ride repeats itself from before.
-----------
Notes:
- 90 seconds = 1 minute, 30 seconds = 1.5 minutes
- The actual heights listed (11 m and 1 m for the max and min respectively) do <u>not</u> play a role in determining the period. So the heights can be anything we want, and the period will stay at 90 seconds.
