Answer:

Doug wrote geometric sequence.

Step-by-step explanation:

a geometric sequence is where we get common ratio between consecutive terms

\text{common ratio}=\frac{a_2}{a_1}

In case of Andre:

On substituting the values so as to find common ratio is

\frac{\frac{3}{8}}{\frac{3}{4}}=\frac{-1}{2}

\frac{\frac{-3}{16}}{\frac{3}{8}}=\frac{-1}{2}

\frac{\frac{-3}{32}}{\frac{-3}{16}}=\frac{1}{2}

Andre did not write a geometric sequence.

In case of Brenda:

On substituting the values so as to find common ratio is

\frac{\frac{-3}{8}}{\frac{3}{5}}=\frac{-5}{8}

\frac{\frac{3}{16}}{\frac{-3}{8}}=\frac{-1}{2}

\frac{\frac{3}{32}}{\frac{3}{16}}=\frac{1}{2}

Brenda did not write a geometric sequence.

In case of Camille

On substituting the values so as to find common ratio is

\frac{\frac{3}{8}}{\frac{3}{4}}=\frac{1}{2}

\frac{\frac{-3}{16}}{\frac{3}{8}}=\frac{-1}{2}

\frac{\frac{-3}{32}}{\frac{-3}{16}}=2

Camille did not write a geometric sequence.

In case of Doug:

On substituting the values so as to find common ratio is

\frac{\frac{-3}{8}}{\frac{3}{4}}=\frac{-1}{2}

\frac{\frac{3}{16}}{\frac{-3}{8}}=\frac{-1}{2}

\frac{\frac{-3}{32}}{\frac{3}{16}}=\frac{-1}{2}

Doug wrote a geometric sequence.

The perimeter of a rectangle is 4040 yards. what are the dimensions of the rectangle with maximum area?
Ivanshal [37]
Let x be the length and y be the width2x + 2y = 40x + y = 20change that into y = mx + b formy= 20 – x
Area =xy = x (20-x) = 20x - x^2Area=-x^2+20xcomplete the square:Area=-(x^2 – 20x + 100) +100=-(x - 10)^2 + 100This is an calculation of a parabola that opens downward with vertex at (10,100), which means maximum area of 100 happens when x, the length=10)Dimensions of the rectangle with maximum area? 10 yds. by 10 yds., a square.
