Answer:

The relation is <u>not</u> a function.

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.

In this case, the answer is no. The input value of 10 corresponds with two output values, 4 and 20. It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.

Therefore, the given relation is <em><u>not</u></em> a function.

In 2010, the world's largest pumpkin weighed 1,810 kilograms. An average-sized pumpkin weighs 5,000 grams.

jekas [21]

Answer:

1,805 kg.

Step-by-step explanation:

We have been given that in 2010, the world's largest pumpkin weighed 1,810 kilograms. An average-sized pumpkin weighs 5,000 grams. We are asked to find the how much the world's largest pumpkin weighs than an average pumpkin.

First of all, we will convert the weight of average pumpkin in kilograms by dividing 5,000 by 1000 as 1 kg equals 1,000 gm.

$\text{The weight of average pumpkin}=\frac{5000\text{ gm}}{\frac{\text{1000 gm}}{\text{ 1 kg}}}$

$\text{The weight of average pumpkin}=5000\text{ gm}\times \frac{\text{ 1 kg}}{\text{1000 gm}}$

$\text{The weight of average pumpkin}=5\text{ kg}$

Now, we will subtract the weight of average pumpkin from world's largest pumpkin's weight.

$1,810\text{ kilograms}-5\text{ kilograms}=1,805\text{ kilograms}$

Therefore, the 2010 world-record pumpkin weighs 1,805 kilograms more than an average-sized pumpkin.

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 $5.29\pi$

At a video store, you have two options for renting movies. You can pay $4 per movie, or you can pay a one-time membership fee of

AfilCa [17]

Let x stand for a movie.

You can pay $4 every movie or $1.50 for every movie plus the original $10

4x = 1.50x +10

-1.50x -1.50x (Subtraction Property of Equality)

2.50x = 10

/2.50 /2.50 (Division Property of Equality)

x = 4

After 4 movies, the membership will cost less.

Round to the nearest tenth if necessary.

mihalych1998 [28]

Distance formula: sqrt((x2-x1)^2 + (y2-y1)^2)

distance = sqrt((-1 -2)^2 + (-5-5)^2)
distance = sqrt(109)

Distance = 10.44
