If a point P(1, 3) is reflected across the line y = 2, what are the coordinates of its reflection image?

1 answer:

4 0

The point P(1, 3) is one unit up of the line y = 2, a refrection image of P(1, 3) across the line y = 2 will be one unit down of the line y = 2.
Therefore, the coordinate of the refrection image is (1, 1).

Answer:

a) t₀ = 1.73205 s

b) 1.0 C

Step-by-step explanation:

(A)

The time dilation (t) observed by an observer at rest relative to the time (t₀) measured by observer in motion is;

$t = \frac{t_0}{\sqrt{1 - \frac{V^2}{C^2}}}$

$t_0 = t \sqrt{1 - \frac{V^2}{C^2}}$ time measured by captain

⇒ $t_0 = 2.0 \sqrt{1 - \frac{0.5^2C^2}{C^2}}$ V = 0.5 c

⇒ t₀ = 1.73205 s

(B)

Speed of the light never exceeds by its real value. The speed of the light in any frame of reference is constant.

∵ It will be "1.0C" or just "C"

What is the measure of X? angles are not necessarily drawn to scale

Schach [20]

Answer:

xº=71º

Step-by-step explanation:

Take the triangle BDH

Once the sum of interior angles of a triangle is 180º:

40º+31º+yº=180º

71º+yº=180º

yº=109º

Once yº and xº are supplementary angles (add up to 180º):

yº+xº=180º

109º+xº=180º

xº=71º

The total number of people in the city surveyed by Annette= 480 people.

Step-by-step explanation:

Let 'X' be the Total Number of people Annette surveyed.

Out of Total people in the city, only 180 people are not interested in a new shopping mall.

Therefore, it is given in the question that 180 is 37.5% of Total number of people surveyed (X).

step 1: 180= (37.5/100)*(X)

step 2: X= (180*100)/37.5

step 3: X= 18000/37.5

step 4: X= 480
