Transforming the rhombus JKLM by dilation with a scale factor of 1/4 and center at D(0, 3), gives;

  • J'(0, 2.5)

  • L(-16, 19)

<h3>What formula can be used to find the coordinates of the image following a dilation?</h3>

From the question, we have;

Center of dilation = D(0, 3)

Scale factor of dilation = 1/4

The given points are;

  • J(0, 1), L'(-4, 7)

The required points are J' and L

Given that the x-coordinate of <em>J </em>is the same as the center of dilation, we have;

The x-coordinate of <em>J' </em>= 0

The formula for finding the coordinates following a dilation is presented as follows;

Dilation;

(x, y) → (k(x - a) + a, k(y - b) + b)

Where;

Center of dilation = (a, b)

Scale factor = k

Therefore;

J(0, 1)

J'(0.25•(0 - 0) + 0, 0.25•(1 - 3) + 3)

The coordinates of <em>J' </em>is therefore;

  • J'(0, 2.5)

L'(-4, 7) = L(0.25(x - 0) + 0, 0.25(y - 3) + 3)

0.25(x - 0) + 0 = -4

Therefore;

x = -16

0.25•(y - 3) + 3 = 7

y - 3 = (7 - 3)/0.25 = 16

y = 19

  • The coordinates of <em>L </em>is<em> </em>therefore (-16, 19)

From a radar station, the angle of elevation of an approaching airplane is 32.5 degree. The horizontal distance between the plan
denis23 [38]

Answer: 42.21 km

Step-by-step explanation:

We can solve this using trigonometry, since we have the following data:

\theta=32.5\° is the the angle of elevation

d=35.6 km is the horizontal distance between the plane and the radar station

x is the hypotenuse of the right triangle formed between the radar station and the airplane

Now, the trigonometric function that will be used is <u>cosine</u>:

cos\theta=\frac{d}{x} because d is the adjacent side of the right triangle

cos(32.5\°)=\frac{35.6 km}{x}

Finding x:

x=\frac{35.6 km}{cos(32.5\°)}

x=42.21 km
