ANSWER
The coordinates of the image are (2,2)
EXPLANATION
The mapping for a reflection across the line y=k is :

We want to find the image of the point (2,-4) after a reflection in the line y=-1.
In this case k=-1.

This simplifies to,


Hence the image is (2,2)
F/3+36=c subtract 36 from both sides
f/3=c-36 multiply both sides by 3
f=3c-108
Answer:
i think. 8 times 12 = 96 times 20 = 1,920
Jackson's method to figure out the height of the mountain is from the
similar triangles formed by the light using the mirror.
Response:
- The height of the mountain is <u>50 feet 8 inches</u>
<h3>Which methods can used to find the height of the mountain?</h3>
The given parameters are;
Distance of the mirror from Jackson = 5 feet
Distance of the mirror from the base of the mountain = 40 feet
Height of Jackson = 6'4'' tall
Required:
The approximate height of the mountain, <em>h</em>
Solution:
The triangles formed by the light from the top of the mountain which is
reflected to Jackson from the mirror, Jackson's height, the height of the
mountain, and their distances from the mirror, are similar triangles.
The ratio of corresponding sides of similar triangles are equal, therefore,
we have;

Which gives;


- The height of the mountain is approximately <u>50 feet 8 inches</u>

Answer:
P = 55 feet
A = 237 sq feet
Step-by-step explanation:
P = 2(4) + (3.14 x 15)
A = (4 x 15) + (3.14 x 7.5²)
