Which figure always has exactly four lines of reflection that map the figure onto itself

1 answer:

6 0

A square has exactly four lines of reflection. The four lines are: the two diagonals of the square, and the two lines that are parallel to the two sides of the square and cut the square into two equal halves. No matter how big the square is, along these four lines, you can always fold the square so that the two parts match up with each other. Other lines do not work.

Using the image below, find the y value for the point that divides the line segment XY into a ratio of 1.2

Ivan

Answer: c) -0.3

<u>Step-by-step explanation:</u>

Consider the left point as (x₁, y₁) and the right point as (x₂, y₂)

then (x₁, y₁) = (-6, -1) & (x₂, y₂) = (5, 1)

x₂ - x₁ = 5 - (-6) = 11

y₂ - y₁ = 1 - (-1) = 2

ratio of a:b = a/(a+b)

1 : 2 = 1/(1 + 2) = 1/3

x-coordinate: x₁ + ratio(x₂ - x₁) = -6 + (1/3) (11) = -7/3

y-coordinate: y₁ + ratio(y₂ - y₁) = -1 + (1/3) (2) = -1/3

A farmer finds that if she plants 60 trees per acre, each tree will yield 45 bushels of fruit. she estimates that for each addit

Mkey [24]

Answer: 60 trees

Explanation:
Even if there are trees planted per acre, the decrease of yield of each tree is significant enough to make it less worthwhile to have more trees than less.

In other words, when she plants 60 trees per acre, she gets 2700 bushels of fruit per acre, because 45 bushels per tree = 45 • 60 = 2700. If you plant another tree, you get the equation 41 • 61 = 2501 because there are 4 less bushels per tree. 2501 < 2700 so 60 per acre would maximize the harvest.

PLEASE SOMEONE HELP!!!!!!!!!!!!!!

<1 and <2 are supplementary angles. They add up to 180 degrees.

92 and <2 are corresponding angles, they have the same measure.

So,<2 = 92 degrees

180-92= 88 degrees

<1= 88 degrees

I hope this helps!
