Answer:
Option 1 is a geometric sequence.
I 1/4, 1/4, 1/4, 1/4
II 1/4, 1/5, 1/6
III 1/4, 1, -4, 1/6
IV 1/4, -4, 1/4, -4
For any geometric sequence there should be a common ratio
To find common ratio we divide consecutive terms
lets check option I
I 1/4, 1/4, 1/4, 1/4
When we divide 1/4 by 1/4 we will get 1
Same 1 for other two terms, so common ratio is 1
Hence the first option is a geometric sequence

The relationship between the years since the tree was transplanted and its height in inches is linear and represented graphically by a line with positive slope and positive y-intercept
Step-by-step explanation:
Their is a linear relation between the years since the tree was transplanted and its height in inches because
- The tree has a constant rate of increasing of its height per year
- Assume that the initial height of the tree when it planted is b inches
- Its height increases m inches per year
- Its height (y) after x years can be expressed in the formula y = m x + b
y = m x + b is the form of the linear equation, where
- m is the slope of the graph of the equation
- b is the y-intercept (value y at x = 0)
The relationship between the years since the tree was transplanted and its height in inches is linear represented graphically by a line with positive slope and positive y-intercept

The area used to make the triangular flag is 15 square inches.
Given
Two of the sides are 8 in.
Lila made a triangular flag to cheer on her favorite sports team.
The perimeter of the flag is 20 inches.
<h3>What is Heron’s formula?</h3>
Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.
Then,
The value of S is;
Therefore,
The area used to make the triangular flag is;
Hence, the area used to make the triangular flag is 15 square inches.
