Answer:

The sum of three products; there are three terms

Step-by-step explanation:

Which of the following best describes the expression 3x + 2y + 8z?

The product of three sums; there are three terms

The sum of three products; there are three terms

The product of three sums; there are six terms

The sum of three products; there are six terms.

As you can see from the options, there is only one that is correct, since the terms are adding up, each term is 3x, 2y, and 8z, these are the three terms that we can find in the expression, and since they are products of a multiplication, they are the sum of three products, and there are only three terms, remember that the word product in math means the result of a multiplication, since 3 is multiplying x 2 is multiplying y and 8 is multiplying z we have three multiplications, or 3 products, and we are adding them up, so the correct option would be The sum of three products; there are three terms.

A sumo wrestling ring is circular and has a circumference of 4 . 6 π meters 4.6π meters. What is the area A A of the sumo wrestl

LUCKY_DIMON [66]

Answer:

$A=5.29\pi$

Step-by-step explanation:

<u>Formula for circumference of a circle is</u>:

Circumference = $2\pi r$

<em>Given circumference of the ring is $4.6\pi$ </em>

<em>Now solving for the radius gives us:</em>

$2\pi r=4.6\pi\\r=\frac{4.6\pi}{2\pi}\\r=\frac{4.6}{2}=2.3$

We know that area of a circle is $\pi r^2$ , substituting the value of r we found, we get the area as:

area (A) = $\pi r^2\\\pi (2.3)^2\\\pi (5.29)\\=5.29\pi$

Hence the Area (A), in terms of $\pi$ is $5.29\pi$

How do you graph and translate a shape

jeka94

See in the explanation

<h2>Explanation:</h2>

Translating a shape is part of that we called Rigid Transformations. This is called like this because the basic form of the shape doesn't change. So this only changes the position of the chape in the coordinate plane. In mathematics, we have the following rigid transformations:

Horizontal shifts
Vertical shifts
Reflections

Horizontal and vertical shifts are part of translation. So the question is <em>How do we graph and translate a shape?</em>

To do so, you would need:

A coordinate plane.
An original shape
Set the original shape in the coordinate plane.
A rule
The translated shape

For example, the triangle below ABC is translated to form the triangle DEF. Here, we have a coordinate plana and an original shape, which is ΔABC. So this original shape has three vertices with coordinates:

A(-4,0)

B(-2, 0)

C(-2, 4)

The rule is <em>to translate the triangle 6 units to the right and 1 unit upward. </em>So we get the translated shape ΔDEF with vertices:

D(2,1)

E(4, 1)

F(4, 5)
