Answer:
Base of the ladder is 3 meters away from the building.
Step-by-step explanation:
Let's use Pythagoras theorem to solve.
Pythagoras theorem says,
Here let horizontal distance is "a''
Vertical distance of window is 4 m
So, b=4
The Rafi leans 5 m ladder against the wall. So, c=5.
Simplify it
Subtract both sides 16
Take square root on both sides
a=±3
So, base of the ladder is 3 meters away from the building.
Exponential form:12^3
Standard form:1728
Expanded form:12x12x12
Answer. Option A. y>3x+2
Explanation. Because the line is dotted, we know it is a > equation. We know that in slope-intercept form, the mx stands for is the slope (rise over run), by looking at the graph, we find that the slope is in fact 3 (or 3/1). For the second part of the equation, we know it’s the y-intercept; therefore, option A is correct because the y-intercept is in fact 2. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.
A cosine equation with 5pi/8 involved brought down by 2. That is the best I can help from what I remember from High School.
Observe that 
is the square of 
, and 625 is the square of 25.
So, your expression is a difference of squares, and as such we can rewrite it as
Now again, is the square of 
, and 25 is the square of 5. So, we have a sum and a difference of squares.
But if we think of 25 as 
, we have again the difference of two squares, so we have
