Perimeter is 2l+2w
100 =2(30) + 2w
100 =60 + 2w
-60 -60
40 = 2w

w=20 meters.

Point M is located at (4, 6) on a coordinate grid. Point M is translated 8 units to the left and 9 units down to create point M.

Answer:

Step-by-step explanation:

You can look at it like a right triangle being made with the vertical part being 9 and the horizontal part being 8, then you want to find the diagonal part. So that's the Pythagorean theorem

$\sqrt{8^2+9^2}=12.042$

Draw a line representing the "rise" and a line representing the "run" of the line, State

Alexxx [7]

Answer:

The slope of the line m = 1

The equation of the straight line x -y -7=0

Step-by-step explanation:

Explanation:-

In the given graph

The points are ( 7,0) and ( 0, -7)

The slope of the line

$m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} } = \frac{-7-0}{0-7} = \frac{-7}{-7} = 1$

The equation of the straight line passing through the point (7,0) and slope m=1

y - y₁ = m (x - x₁)

y - 0 = 1( x-7)

y = x -7

x - y -7=0

Final answer:-

The slope of the line m = 1

The equation of the straight line x -y -7=0

Determine if each sequence is arithmetic, geometric, or neither.

Len [333]

Answer:

geometric
arithmetic
neither (Fibonacci sequence)

Step-by-step explanation:

If ratios are the same, it is geometric:

8/4 = 16/8 = ... = 2

If differences are the same, it is arithmetic:

-4-(-8) = 0 -(-4) = ... = 4

If neither is the case, it is neither:

3-2 ≠ 5 -3

3/2 ≠ 5/3

In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)
