Answer:
f(17) = $15.75
The amount it takes for a trip of 17 miles is $15.75
Step-by-step explanation:
Here, we want to calculate f(17)
The equation is given as;
y = 0.75x + 3
For f(17), substitute x for 17
y = 0.75(17) + 3
y = 12.75 + 3
y = $15.75
What f(17) means is that the ride was for 17 miles
$15.75 is for a trip of 17 miles
Answer:
the 73rd term of the arithmetic sequence is -964.
Step-by-step explanation:
The common difference in this arithmetic sequence is 13. This is obtained by subtracting 28 from 41. The first term is a(1) = -28.
The arithmetic sequence formula is a(n) = a(1) + d(n - 1), where d is the common difference and -28 the first term.
Then, in this case, a(n) = -28 - 13(n - 1), and
a(73) = -28 - 13(73 - 1) = -964
Answer:
t = 1/2 hour
Step-by-step explanation:
20480 = 80
20480 = 80
20480/80 =
256 =
x = 4
doubling period
2 =
t = 1/2 hour
The function is decaying.
<u>Step-by-step explanation:</u>
Given:
The above equation can also write as below,
Now from the function we can see that as we are increasing the value of x the value of function is decreasing. Let take some values of x and then find out the value of function at those value of x
When x = 1
,
When x = 2,
When x = 3,
So, from the above examples, we can see that the value of function is decreasing on increasing the value of x. Hence the function is decay
