What is the counterclockwise rotation shown below? 13 pts.

AveGali [126]

Answer:

<u>270° around the origin</u>

Step-by-step explanation:

As shown at the graph

ΔABC is translated to ΔA'B'C'

A(0,3) , B(-2,2) , C(-1,1)

A'(3,0) , B'(2,2) , C'(1,1)

So, if the coordinate of the pre-image is (x,y)

The coordinate of the image will be (y, -x)

Which mean the rule will be (x,y)→(y,-x)

The previous rule is the rule of rotation 270° counterclockwise

So, the answer is <u>270° around the origin</u>

A 10-foot ladder leans against a wall with its foot braced 3 feet from wallÍs base. How far up the wall does the ladder reach?

iren2701 [21]

The answer is √91 feet (which is the same as 9.54 feet).

Imagine this as a right triangle. A length of the foot is actually a hypotenuse (c). The distance from wall's base to the ladder foot is one of the sides of the triangle (let it be a).
So, using the Pythagorean theorem:
c² = a² + b²
It is given:
c = 10 feet
a = 3 feet
b = ?
c² = a² + b²
⇒ 10² = 3² + b²
100 = 9 + b²
b² = 100 - 9 = 91
⇒ b = √b² = √91 ≈ 9.54 feet

Skew lines a and b represent Donna's and Charlie's paths as they simultaneously walk on the first and second level of a shopping

vlabodo [156]

Answer: They cannot meet because two skew lines do not intersect each other.

Explanation:

Skew lines is a concept used in geometry to define lines that do not intersect each other but are not parallel.

In this case, the lines are not parallel because they lie in different planes, which in turn, do not intersect each other.

Therefore, runing the lnes in different planes and in different directions, they cannot not, in spite of not being parallel, intersect each other, which is called that the lines are skewed.

Donna's and Charlie's paths are an exelent illustration of what skew lines are: since Donna's and Charlie are in different levels, as long as each remains in parallel levels, their paths wiil not meet each other.
