A. Yes, the value of this function is 8 when x is 15.
B. False. I noted right away that the ordered pair (0,5) is not included, and some of the ordered pairs included do not represent the given function.
C. Yes, f(5) = 6. See (A) above.
D. False. The range of this function is the set of integers between 5 and 13 inclusive.
I would assume you would get a negative number and a positive number either way, but they would be the same number just one is negative and one is positive
You first need to change 2 1/3 into a mixed fraction, which would be 7/3 and multiply by 5/1, which would be 35/3, and then divide 35 and 3 to get and answer of 11 2/3, which is the answer.
Answer:
Maria is not correct.
The graph of y = 3x grows at an increasingly increasing rate, but the graph of y = 3x2 grows at a constantly increasing rate.
Therefore, the graph of y = 3x will eventually surpass the graph of y = 3x2.
Step-by-step explanation:
Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:
h(t) = 10 - 0.75t
The height will be of 0.25 inches when h(t) = 0.25, hence:
0.25 = 10 - 0.75t
0.75t = 9.75
t = 9.75/0.75
t = 13 hours.
