Write in expression
multiply the quotient of 10 and r by 4

Answer:

r=8

Step-by-step explanation:

Because 16 divided by 2 is 8

The radius of a circle has a circumference of 16 at r = 8.

Given: the formula for the circumference of a circle is C = 2r, where r is the radius and C is the circumference.

The circumference of a circle is equal to π.

π ≈ 3.14

multiplied by the diameter of the circle.

Therefore, the diameter has twice the length of the radius.

In equation form:

2r = d.

2r = 16.

r = 8.

Note, 2r = d,

Then, the equation C = 2πr holds and can be used in place of C = πd.

The radius of a circle has a circumference of 16 at r = 8.

to do this all you have to do is make the denominator 1 and the numerator should be 1.566666667

Answer:

a = 20.79cm ( 2 decimal places)

Step-by-step explanation:

find the length of the identical sides (i name it "x") first using Pythagoras theorem

[tex]14.8^{2}[/tex] = [tex]x^{2} + x^{2}[/tex]

219.04 = [tex]2x^{2}[/tex]

[tex]x^{2}[/tex] = 219.04/2 = 109.52

x = [tex]\sqrt{109.52}[/tex]

now find a,

[tex]a^{2}[/tex] = [tex](\sqrt{109.52}) ^{2}[/tex] + [tex](7.5 + \sqrt{109.52}) ^{2}[/tex]

[tex]a^{2}[/tex] = 109.52 + 322.7477 = 432.2677

a = [tex]\sqrt{432.2677}[/tex] = 20.791048

Answer:

19 inches is the correct answer.

Step-by-step explanation:

Side 1 = 10 inches

Side 2 = 15 inches

It is given that it is an obtuse angle triangle i.e. the largest angle of the triangle is more than [tex]90^\circ[/tex].

Let us suppose, that the triangle be a right angle triangle, then the largest angle will be [tex]90^\circ[/tex]. The largest side is known as Hypotenuse.

As per pythagoras theorem:

[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]

[tex]\Rightarrow 10^{2} + 15^{2} = Hypotenuse^2\\\Rightarrow 325 = Hypotenuse^2\\\Rightarrow Hypotenuse = 18.04\ inches[/tex]

So, largest side comes out be 18.04 inches.

But actually, the largest angle is more than [tex]90^\circ[/tex] so the largest side will also be greater than 18.04 inches.

Hence, the answer is:

Smallest possible whole number length of unknown side will be 19 inches.

Multiply the original coordinates by 1/3

Answer:

2/3

Step-by-step explanation:

32/48= 16*2/16*3= 2/3

Answer:

The correct answer is D. 360°

Step-by-step explanation:

The sum of all the exterior angles of a regular n-gon or a polygon is always equal to 360°.

Let us consider the image attached.

First of all let us consider the triangle.

As per the property of exterior angles: The exterior angle is equal to the sum of 2 opposite interior angles.

[tex]\Rightarrow \angle 1=\angle B + \angle C\\\Rightarrow \angle 2=\angle A + \angle C\\\Rightarrow \angle 3=\angle A + \angle B[/tex]

Where [tex]\angle A, \angle B\ and\ \angle C[/tex] are the interior angles of the triangle.

Adding the above equations:

[tex]\angle 1 +\angle 2 +\angle 3 = 2 \times (\angle A +\angle B +\angle C )[/tex]

The sum of interior angles of a triangle is always equal to 180°

[tex]\angle A +\angle B +\angle C = 180^\circ[/tex]

[tex]\angle 1 +\angle 2 +\angle 3 = 2 \times 180^\circ\\\Rightarrow \angle 1 +\angle 2 +\angle 3 = 360^\circ[/tex]

Hence, proved that the sum of exterior angles is [tex]360^\circ[/tex].

So, the correct answer is D. [tex]360^\circ[/tex]

Answer:

41

Step-by-step explanation:

Matrix Multiplication follows a row-column format. In order to compute this, you must be familiar with vector dot products.

With that in mind, lets get straight into it.

The order that matrix multiplication follows means that the terms in the result are filled in left to right, then top to bottom.

Therefore, a21 will be the 3 value that is computed. This is important becuase this allows to directly compute a21, instead of using up a lot of time computing all the values before.

As a21 is located in the bottom row 1st column, we take the dot product of the 2nd row in matrix 1 and the 1 column in matrix two.

So we have:

(7 2) dot (5 3) = 7*5 + 2*3 = 41

Answer:

Step-by-step explanation:

The next term of a Fibonacci sequence is generated by taking the sum of the 2 preceding value of the sequence. Given the the first and third term of a Fibonacci sequence to be x and y

x, _, y...

let the second term be a, fourth term be b and fifth term be c to have the sequence;

x, a, y, b, c...

According to the definition;

x+a = y... 1

a+y = b... 2 and;

y+b = c... 3

From equation 1, a = y-x

Substituting a = y-x into equation 2 to get b we have;

(y-x)+y = b

2y-x = b

b = 2y-x

Substituting b = 2y-x into equation 3 to get 'c'

y +  2y-x = c

3y-x = c

c = 3y-x

The second term of the sequence is y-x

The fourth term of the sequence is 2y-x

The fifth term of the sequence is 3y-x
