Answer:
The Answer is: B.
Step-by-step explanation:
The form of the equation is:
f(x) = ab^x
When b is greater than 0 and less than 1, the function is an Exponential Decay Function.
B. is f(x) = (.08)^x
In this case, a = 1
Next time, please include the directions for the problem you post. Here it appears that you have given the values of I, P and t two times each.
Unfortunately, I have to guess what you're looking for.
Assuming that I=$26.25 is the interest earned on Principal P=$500, and that t is the length of time over which the Principal earns interest,
I=Prt. With I, P and t given, it's obvious that our job is to find the annual interest rate, r. So, from I=Prt, we get
$26.25 = $500 (r) (1.5 years) Solve this for the interest rate, r.
Express r both as a decimal fraction and as the equivalent percentage.
Answer: Andy will pay $12.675 in interest for one interest
Step-by-step explanation:
Since we have given that
Remaining balance of Andy on his credit card = $845
APR of his credit card = 18%
So, Rate of interest for one month will be

Interest will be paid for one month is given as

Hence, Andy will pay $12.675 in interest for one interest .
Answer:
The error mentioned is a systematic error.
Step-by-step explanation:
The glass beads used for mass measurements was noticed to be significantly smaller than those used for volume measurements.
The formula for density is =
.
So if we try to experimentally determine the value of density of glass then the beads for measuring the mass are much smaller than the beads for measuring volume.Thus in this case we can see that the density measured will actually be less than the actual density of glass.
However since this error can be seen and quantified and corrected it is not a random error, but it is a systematic error.
