Answer:

The answer to your question is:

Step-by-step explanation:

24.-

y = 5x - 6

x + 5y = 5 5y = - x - 5 y = -(1/5) x - 1

Because of the slopes "5" and "-1/5" the lines are perpendicular.

25.- 2x + y = 10 y = -2x + 10 slope = -2

-6x - 3y = 3 -3y = 6x + 3 y = -2x - 1 slope = -2

x - 2y = 8 -2y = - x + 8 y = (1/2) x - 4 slope = 1/2

Lines a and b are parallels and perpendicular to c

Use the following information to answer all parts of question 3.3a: What is the area of the triangle? (Area of triangle = 1/2*b*

Anit [1.1K]

Answer:

See below ~

Step-by-step explanation:

3a : Area of the triangle

A = 1/2bh
A = 1/2 x 10 x 8
A = 5 x 8
A = 40 m²

3b : Area of the semicircle

Finding the radius (equal to 1/2 of the triangle hypotenuse)
Apply Pythagorean Theorem here
√8² + 10² = d
√64 + 100 = d
d = √164
d = 2√41
r = √41

A = πr²/2
A = 3.14 x (√41)² / 2
A = 1.57 x 41
A = 64.4 m² (nearest tenth)

A triangle is dilated with the center of dilation at point U. Point E is a vertex of the triangle and point E ′ E' is the corres

Snezhnost [94]

Answer: $scale\ factor=5$

Step-by-step explanation:

By definition, a Dilation is a transformation in which the image has the same shape as the pre-image but size changes.

The center of dilation is a fixed point in the plane, and the scale factor is the ratio of the corresponding sides of the image to the pre-image.

Based on the information provided in the exercise, you know that:

$UE = 2\ cm\\\\U'E'=10\ cm$

Thererefore, you can determine that the scale factor is:

$scale\ factor=\frac{10\ cm}{2\ cm}\\\\scale\ factor=5$
