Answer:
its answer is 5z or 5×z
Step-by-step explanation:
becoz product means (×)
thats why 5z or 5×z is the answer
Answer:
Explicit: -2*2^(n-1)
Recursive: 2*aₙ₋₁
Step-by-step explanation:
To write a explicit formula for this geometric sequence you follow the following formula/template
Firstnumber*commonratio^(n-1)
Seeing that the common ratio is 2 we can start plugging numbers in and get
-2*2^(n-1)
For a recursive formula we follow the following template
common ratio * the n-1 term
So we could write this as
2*aₙ₋₁
If Samuel can type 40 words per minute, he can type 
words in 
minutes. So, the amount of minutes you're interested in is the solution of the equation
minutes.
Since 8750/60 is 145 with reminder 50, Samuel can type the required amount of words in 145 hours and 50 minutes.
