Mathematics
1 answer:
Sergio [31]3 years ago
8 0

Answer:

  • 5 cm

Step-by-step explanation:

<u>Area of circle P with radius r:</u>

  • A = πr²

<u>Area of quarter circle Q with radius 20 cm:</u>

  • A = 1/4π*20² = 100π

<u>Area of Q is 4 times the area of P:</u>

  • 4*πr² = 100π
  • r² = 25
  • r = √25
  • r = 5 cm

Write an equation of the line that passes through the given points (-4,8) and (2,2)
Nikitich [7]

Answer:

y=-x+4

Step-by-step explanation:

Slope= Difference in y over difference in x position:

(2-8)/(2--4) --> -6/6 --> <u>-1</u>

The slope is -1

We can put what we have so far in slope intercept form: y=-1x+b

The y-intercept (also known as b) in this equation is 4

In slope-intercept form this line would be written as y=-1x+4,

or simply just y=-x+4

Triangle ABC with vertices A(4, −6), B(2, −8), and C(−10, 4) is dilated by a scale factor of 2 to obtain triangle A′B′C′. Which
ira [324]

Answer:

  It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8)

Step-by-step explanation:

Dilated triangles are <em>never congruent</em>, only <em>similar</em> (unless the dilation factor is exactly 1).

The coordinates of an image dilated about the origin are those of the pre-image multiplied by the dilation factor. For example,

  A' = 2A

  A'(8, -12) = 2×A(4, -6)

These facts are all you need to know to choose the correct answer (shown above).
