Use set notation to write the members of the following set, or state that the set has no members. Odd numbers between 2 and 82 t

adell [148]

Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

$D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}$

The odd multiples of 9, $m$ , in the range $2\le m \le 82$ form the set

$\{9,27,45,63,81\}$

Each member of the set is a term of the arithmetic progression

$U_n=18n+9$

where the values of $n$ range from 0 to 4, or $0\le n\le 4$

Putting these facts together, we get the result

$D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}$

Hank's pickup can travel 65 miles on 5 gallons of gas. How many gallons will Hank's pickup need to travel 26 miles?

taurus [48]

Answer:

2 gallons

Step-by-step explanations:

1)Divide 26 by 65, then multiply that number by 5

26 / 65=.4 or 40%
.4 x 5 = 2

2)Divide 65 by 5, then divide 26 by that number

65 / 5 = 13
26 / 13 = 2

The graphs below have the same shape. What is the equation of the red graph?

cluponka [151]

We claim that the answer is $y=-x^2.$ Since the two graphs both open down, and all the answer choices, in addition to the equation of the blue graph, are quadratic polynomials, the leading coefficient must be negative. This immediately rules out answer choices A, B, and C, leaving D as the answer.
