Imagine the side of the building is one side to a triangle and the second would be from the top of the building to the point where the shadow ends and the third is from the base of the building to the point where the shadow ends. Just use the pythagoreon theorem to find stuff. I can't solve the problem you gave because you would need the height of the building
Without more information, I assume it's a square and it's w/l =6.5 cm
A² + b² = c²
Where a and b are the legs and c is the hypotenuse
So, plug in 10 for one of the legs and 24 for the other leg
c will be left blank because that is what you are trying to find, the hypotenuse
10² + 24² = c²
100 + 576 = c²
676 = c²
Take the square root of both sides of the equation to isolate c
√676 = √c²
Square of c and the square root cross out on the right
Take the square root of 676
c = 26
So, the length of the hypotenuse is 26 centimeters
The answer is B. The actual reciprocal is 7/2, since the answer means isn't there its means the reciprocal of the negative or positive sign
Answer:
and 
Step-by-step explanation:
The function is given as 
<em>to find inverse, we follow the steps shown below:</em>
<em>1. write "y" in place of "f(x)"</em>
<em>2. interchange "x" and "y"</em>
<em>3. solve for the new "y"</em>
<em>4. replace y with f^-1(x)</em>
<em />
Let's do this:
These 2 are the inverse functions.
