<h3>
Answer: Choice A</h3>
The first line shown in choice A is
which means "the first term is -2"
The next line in choice A means "the nth term (
) is found by multiplying the prior term (
) by 8". Put another way: multiply each term by 8 to get the next term.
first term = -2
second term = 8*(first term) = 8*(-2) = -16
third term = 8*(second term) = 8*(-16) = -128
fourth term = 8*(third term) = 8*(-128) = -1024
and so on.
Answer:
15.5 feet
Step-by-step explanation:
Given:
Patty is building a rope ladder tree house she needs two 4 foot pieces of rope for the sides of the ladder.
She needs 6 pieces of rope each 15 inches long for the steps.
Question asked:
How many feet of rope does patty need to make the ladder ?
Solution:
She needs for the sides of the ladder = Two 4 foot pieces of rope
= 2
4 feet = 8 feet
She needs for the steps of the ladder = 6 pieces of 15 inches long rope
= 6
15 inches = 90 inches
Convert 90 inches into feet:-
12 inches = 1 feet
1 inches = 
90 inches = 
Patty needs total rope = 8 feet + 7.5 feet
= 15.5 feet
Thus, Patty needs 15.5 feet of rope to make the ladder.
Answer: 0.813
Step-by-step explanation:
Let A be the event describes the number of residents believed that the amount of violent television programming had increased over the past 10 years.
& B be the event describes the number of residents believed that the amount of violent television programming had decreased over the past 10 years.
Given : n(A)=721 ; n(B)=454 ; n(A∩B)=362
We know that ,

i.e. 
Also, the total number of U.S. residents surveyed n(S)= 1,000
Then, the proportion of the 1,000 U.S. residents believed that either the amount of violent programming had increased or the overall quality of programming had decreased over the past 10 years will be :-

Hence, the required answer = 0.813
I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:

Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.
