A sequence will be arithmetic if there's a constant difference between terms.
The first sequence is not arithmetic, since the differences between the terms of the sequence are
A sequence is geometric if there's a constant scaling factor being applied to each successive term. To determine if such a constant is there, take the ratio of successive terms.
The first sequence is also not geometric, because the ratios of consecutive terms are
So the first sequence would be assigned (N), which rules out options B and D. Do the same for the next two sequences, which are the only ones you'd need to check.
Answer:
$5
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
putting time into years for simplicity,
3 months ÷ 12 months/year = 0.25 years,
then, solving our equation
I = 500 × 0.04 × 0.25 = 5
I = $ 5.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 4% per year
for 0.25 years (3 months) is $ 5.00.
Answer:
5. not a function
6. function
7. not a function
8 function
9. not a function
10 function
Step-by-step explanation:
5. this fails the vertical line test. Since a vertical line would touch more than one point this is not a function
6. this is a function. Each input (or x) has only one output, so it is a function
7. This is not a function . X=2 goes to more than one y value x =2 goes to y=5 and y=6. so it is a relation not a function
8. this passes the vertical line test. Since a vertical line does not touch more than one point this is a function
9. This is not a function . X=5 goes to more than one y value x =5 goes to y=-4 and y=1. so it is a relation not a function
10. this is a function. Each input (or x) has only one output, so it is a function
<h3>
Answer:</h3>
12 3/4 miles
<h3>
Step-by-step explanation:</h3>
Eric is increasing his distance by 2 3/8 miles per day. In 2 more days, his distance will be 2×(2 3/8) = 4 3/4 miles more than on Wednesday.
... 8 + 4 3/4 = 12 3/4 . . . . miles on Friday
_____
<em>Rate of increase</em>
The difference between Tuesday and Monday is ...
... 5 5/8 - 3 2/8 = 2 3/8
The difference between Wednesday and Tuesday is ...
... 8 - 5 5/8 = 2 3/8
Thus, it appears that Eric is jogging 2 3/8 mile more each day than the day before.
