Step-by-step explanation:
When an ordered pair refers to the location of a point in the coordinate plane, they are called the coordinates of the point. The order is important because a point named by the ordered pair ( 5, 3 ) is not at the same location as the point named by the ordered pair ( 3, 5 ).
Cos Y = 8/17
sin Y = 15/17
tan Y = 15/8
The sequence is an arithmetic sequence and the expression used to find the nth term would be 3n option fourth I and II is correct.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a sequence:
3, 6, 9, 12…
First term a = 3
Common difference d = 6 - 3 = 3
This is an arithmetic sequence.
nth term of the arithmetic sequence:
a(n) = 3 + (n-1)(3)
a(n) = 3n
Plug n = 5
a(5) = 3(5) = 15
Thus, the sequence is an arithmetic sequence and the expression used to find the nth term would be 3n option fourth I and II is correct.

The flour needed for 18 dozen cookies is 4.5 pounds.
The number of cookies that can be made with 10 pounds of flour is 40 cookies.
<h3>How much flour is needed?</h3>
The first step is to determine the flour needed for 1 dozen cookies.
Flour needed = 3/12
Flour neeeded for 18 dozens = 3/12 x 18 = 4.5 pounds
<h3>
How much cookies can be made?</h3>
The first step is to determine the number of cookies that can be made with one pound of flour:
12/3 = 4
Number of cookies that can be made iwth 10 pounds of flour = 4 x 10= 40 cookies
