Answer:
9/32 of the cookie was left for Stephanie to eat after lunch
Step-by-step explanation:
Anastasia’s mom baked a giant sugar cookie for her birthday.
On her birthday, ⅝ of the birthday cookie was eaten.
So, remaining cake =
The next day her brother ate ¼ of what remained.
Amount of cake eaten by her brother = 
So, remaining cake = 
Hence 9/32 of the cookie was left for Stephanie to eat after lunch
Exponential functions are related to logarithmic functions in that they are inverse functions. Exponential functions move quickly up towards a [y] infinity, bounded by a vertical asymptote (aka limit), whereas logarithmic functions start quick but then taper out towards an [x] infinity, bounded by a horizontal asymptote (aka limit).
If we use the natural logarithm (ln) as an example, the constant "e" is the base of ln, such that:
ln(x) = y, which is really stating that the base (assumed "e" even though not shown), that:

if we try to solve for y in this form it's nearly impossible, that's why we stick with ln(x) = y
but to find the inverse of the form:

switch the x and y, then solve for y:

So the exponential function is the inverse of the logarithmic one, f(x) = ln x
The answer to that problem si 6-25+2x
A, C, and E seem all right. In letter form: 1st 3rd and 5th
Answer:
probability the spy is able to unlock the tablet on his first try.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
1 correct password, so 
Total outcomes:
Nine-digit codes.
For each digit, there are 10 possible outcomes. So

What is the probability the spy is able to unlock the tablet on his first try?
