You deposit $365 into a savings account after one year the amount in the account is $428 which expression describes the percent of increase in the account balance
A.365/428 x 100
B.428-365/428
C.428-365/428 x 100
D.428-365/365 x 100

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

d is ur answer hopes this i dont really know how to explain it to u.
