Use the Pythagorean theorem to obtain the function​ D(x) for the length of the diagonal of a double square of width x.
Yuri [45]

Answer:

D(x)= x\sqrt{2}

Step-by-step explanation:

Given

Side = x

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

D^2= Side^2 + Side^2

Substitute x for Side

D^2= x^2 + x^2

D^2= 2x^2

Take the square root of both sides

D= \sqrt{2x^2

Split

D= \sqrt{2} * \sqrt{x^2

D= \sqrt{2} * x

D= x\sqrt{2}

Express as a function.

D(x)= x\sqrt{2}

zmey [24]

\boxed{27.422}

We will use order of operations to add and subtract from left to right to solve this equation.

26.8 + 0.65 = 27.45

The equation now looks like:

27.45 - 0.028 = 27.422

Therefore, your answer is 27.422.

A circle with circumference 6 has an are with a 20° central angle.
Marysya12 [62]

Answer:

AHH! Geometry!

Thanks!

The arc has a length of 1/3

Step-by-step explanation:

So you first start off with this:

\frac{20}{360}

This is because a circle is 360 degrees, and we are talking about a 20 degree arc.

Simplifying, we get \frac{1}{18}

So then, you multiply the circumference with this "factor"

\frac{1}{18} *6=\frac{6}{18}=\frac{1}{3}

Hope this helps!

P.S. Stay Safe during quarantine!
