Karen opens a savings account with $1500. She deposits $100 every month into the account that has a 0.85% interest rate, compoun
2 answers:
Formula is
D represents the amount of a regular deposit
r represents the annual interest rate
m is the number of equal compounding period
t the time in years,
F is the future value
D = 100, r= 0.85%= 0.0085, m= 1 and t=10
m*t= 1*10 = 10
Plug in all the values in the formula
= 1039.13
Karen opens a savings account with $1500
Already he has 1500
So account balance = 1500 + 1039.13 = $2539.13

Answer:
B the range, the x- and y-intercept
Step-by-step explanation:
the domain stays the same : all values of x are possible out of the interval (-infinity, +infinity).
but the range changes, as for the original function y could only have positive values - even for negative x.
the new function has a first term (with b) that can get very small for negative x, and then a subtraction of 2 makes the result negative.
the y-intercept (x=0) of the original function is simply y=1, as b⁰=1.
the y-intercept of the new function is definitely different, because the first term 3×(b¹) is larger than 3, because b is larger than 1. and a subtraction of 2 leads to a result larger than 1, which is different to 1.
the original function has no x-intercept (y=0), as this would happen only for x = -infinity. and that is not a valid value.
the new function has an x-intercept, because the y-values (range) go from negative to positive numbers. any continuous function like this must therefore have an x-intercept (again, y = the function result = 0)
