Answer:

The following numbers ARE functions:

2, 3, 6, 7, 9, 12

Step-by-step explanation:

A function is only possible if the x values have NO REPEATING NUMBER!!!

Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.

<u>Question 1</u> has the 8 and 4 with 2 numbers.

<u>Question 4</u> the 3 repeating. (There are 2 dots over the 3)

<u>Question 5</u> has numbers 1 and 5 repeating many times

<u>Question 8</u> numbers 1 and 2 are repeated twice

<u>Question 10</u> number 3 repeats twice

<u>Question 11</u> has the 1 repeated

Find the 7th term of the geometric sequence whose common ratio is 1/3 and whose first term is 5.
wolverine [178]

Answer:

t_7 =\frac{5}{729}

Step-by-step explanation:

We are given that:

First term (a) = 5

common ratio (r) =\frac{1}{3}

The nth term of a geometric sequence is given as:

t_n =ar^{n-1} \\\therefore t_7 =5\times \bigg(\frac{1}{3}\bigg) ^{7-1} \\\therefore t_7 =5\times \bigg(\frac{1}{3}\bigg) ^{6} \\\therefore t_7 =5\times \bigg(\frac{1}{3}\bigg) ^{6} \\\therefore t_7 =5\times \frac{1}{729}\\\\\huge\red{\boxed{\therefore t_7 =\frac{5}{729} }}

Thaddeus models the number of hours of daylight in his town as
AfilCa [17]

Option (A) :  least: 10 hours; greatest: 14 hours

The function f(x) = sin x has all real numbers in its domain, but its range is

−1 ≤ sin x ≤ 1.

How to solve such range questions?

Such questions in which every term is in addition and its range is asked is simplest ones to solve if we know the range of each of term. This can be seen from this question

Given: d(t) = 2sin(xt) + 12

=  −1 ≤ sin (xt) ≤ 1.

=  −2≤ 2 sin (xt) ≤ 2.

=  10 ≤ 2sin (xt) + 12 ≤ 14

=   10 ≤d(t) ≤ 14

Thus  least: 10 hours; greatest: 14 hours
