We know, final dimension = initial dimension * dilation factor
= 3 * 1/5 = 0.6
& 6 * 1/5 = 1
In short, Your Answer would be Option D) <span>0.6 ft × 01 ft
Hope this helps!</span>
Complete question is;
A 21 ft ladder is leaning against a tall wall with the foot of the ladder placed at 7 feet from the base of the wall and the angle of elevation is?
Answer:
θ = 70.5°
Step-by-step explanation:
The angle of elevation simply means the angle that the ladder makes with the ground. Let's call this angle θ.
I've attached a diagram showing the triangle made by this ladder and the wall.
From the attached diagram, we can see the triangle formed by the ladder and the wall.
We can find the angle of elevation θ from trigonometric ratios.
Thus;
7/21 = cos θ
cos θ = 0.3333
θ = cos^(-1) 0.3333
θ = 70.5°
has y = 0 as a solution.
Selection B is appropriate.
The event that either M1 or M2 fails has probability
by the addition rule. Failure events are independent, so
so that
Denote this probability by 
. Then 
follows a geometric distribution with this parameter and has density
The expectation is 
.
Answer:
One of the points will be at (0,-10)
One of the points will be at (5/2,0)
The slope is 4
Step-by-step explanation:
Just look at a graph that has the points close to the ones at the top. Good luck, and have a nice day.
