Functions and Geometry
Sometimes we need to express areas, volumes, and distances in terms of unknown quantities (or variables). When we can find such expressions, they can be referred to as functions. Let's recall the area of a rectangle is A=wl, being w its wide and l its length
Please refer to the image below. The length of the swimming pool is l and its width is w. Its area is
We know the length is twice as long as its width, l=2w, so
The sidewalk is 2 feet wide. The length of the pool and its sidewalk is
Similarly, the width of the pool+sidewalk is
The area of the pool+sidewalk is
We know that l=2w, so
The area of the sidewalk alone is the subtraction of both areas
Simplifying
The answer is 0.04
All you have to do is go to a calculator and type 4 then put %
Answer:
<h3>The option A)
is correct answer.</h3><h3>The correct simplification for the given expression
is
</h3>
Step-by-step explanation:
Given expression is x to the 12th power times z to the 11th power all over x to the 2nd power times z to the 4th power.
The given expression can be written as
<h3>To choose the correct simplification of the given expression :</h3>
Now we have to simplify the given expression as below
( by using the identity )
( by using the identity )
∴
<h3>The correct simplification for the given expression
is
</h3><h3>Hence option A)
is correct answer.</h3>
Answer:
Step-by-step explanation:
From the given information:
The diagrammatic interpretation of what the question is all about can be seen in the diagram attached below.
Now, let V(x) be the time needed for the runner to reach the buoy;
∴ We can say that,
In order to estimate the point along the shore, x meters from B, the runner should stop running and start swimming if he want to reach the buoy in the least time possible, then we need to differentiate the function of V(x) and relate it to zero.
i.e
The differential of V(x) = V'(x) =0
=
squaring both sides; we get
By cross multiplying; we get
