Is 44 a perfect square or a non-perfect square?

Answer:

Option R

Step-by-step explanation:

The point S is the end point of ray.

What is line?

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.

According to the given information,

A ray's endpoint is a single point that denotes the conclusion of a line segment. In this instance, only one of the three lines that extend from point S contains a ray's terminus.

We must comprehend a ray's qualities in order to establish which location is the endpoint of a ray.

A ray originates at a single place and travels in one direction indefinitely. The beginning of the line segment is the endpoint of a ray.

We can see from the provided lines that the vertical line runs from point S via point R. Since it doesn't go on forever in one direction, this is not a ray example.

Similar to the vertical line,

The horizontal line also extends from point S through point T,

But it does not go on forever.

The third line is a ray because it is infinitely long in one direction and extends right and up from point S via point U.

Therefore, point S, the beginning of the line, is the endpoint of this ray.

Answer: 4 or [tex]\sqrt{4 * 4}[/tex]

To find the square root of a number, remember that there will be two factors that are the same that will give you the product.

Lets start from 1:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.

4 and 4 are the same numbers.

Therefore, [tex]\sqrt{16}[/tex] = 4

It can also be written as [tex]\sqrt{4 * 4}[/tex]

Answer:

the answer is 4

Step-by-step explanation:

I use a calulator but if you dont have one then the way to do square roots is find a number say 4 and put it to the 2 power and it equaks 16 (4^2)=16. I cant really explain much more

Answer:

[tex]x = 10[/tex]. In other words, there number of girls is [tex]10[/tex].

Step-by-step explanation:

The average of a number of measurements is equal to the sum of these measurements over the number of measurements.

[tex]\displaystyle \text{Average} = \frac{\text{Sum of measurements}}{\text{Number of measurements}}[/tex].

Rewrite to obtain:

[tex]\begin{aligned}& \text{Sum of measurements}= (\text{Number of measurements}) \times (\text{Average}) \end{aligned}[/tex].

For this question:

[tex]\begin{aligned}& \text{Sum of heights of boys} \\ &= (\text{Number of boys}) \times (\text{Average height of boys}) \\ &= 15 \times 125 = 1875\end{aligned}[/tex].

[tex]\begin{aligned}& \text{Sum of heights of girls} \\ &= (\text{Number of girls}) \times (\text{Average height of girls}) \\ &= x \times 120 = 120\, x\end{aligned}[/tex].

Therefore:

[tex]\begin{aligned}& \text{Sum of boys and girls} \\ &= \text{Sum of heights of boys} + \text{Sum of heights of girls}\\ &= 1875 + 120\, x\end{aligned}[/tex].

On the other hand, there are [tex](15 + x)[/tex] boys and girls in total. Using the formula for average:

[tex]\begin{aligned}& \text{Average height of boys and girls} \\ &= \frac{\text{Sum of heights of boys and girls}}{\text{Number of boys and girls}} \\ &= \frac{1875 + 120\, x}{15 + x}\end{aligned}[/tex].

From the question, this average should be equal to [tex]123[/tex]. In other words:

[tex]\displaystyle \frac{1875 + 120\, x}{15 + x} = 123[/tex].

Solve this equation for [tex]x[/tex] to obtain:

[tex]1875 + 120\, x= 123\, (15 + x)[/tex].

[tex](123 - 120)\, x = 1875 - 123 \times 15[/tex].

[tex]x = 10[/tex].

In other words, the number of girls here is [tex]10[/tex].

Answer:

See below.

Step-by-step explanation:

1)

For Ben's social media post, we are told that it was initially shared to only 2 people. However, each of those shares it with 3 people. In other words, Ben's post triples every day. This means that the rate of growth is 3. Thus, Ben's post as an exponential function is:

[tex]f(x)=2(3)^x[/tex]

The 2 represents the initial amount at day 0, and the 3 represents the rate at which the post grows each day.

2)

Similarly, Carter's post was originally sent to 10 people. However, each of the 10 shares it with two others. Therefore, it doubles each day. Thus, the rate is 2. So, Carter's exponential function is:

[tex]f(x)=10(2)^x[/tex]

The 10 represents the initial amount while the 2 represents the rate.

3)

I've use Desmos to graph the functions. Refer to the picture attached. Red is Amber, blue is Ben, and green is Carter.

4)

To find out the number of shares each student's post will receive on day 3 and day 10, simply plug the numbers into the functions. Therefore:

For Amber:

Day 3:

[tex]f(3)=3(4)^3=192[/tex]

Day 10:

[tex]f(10)=3(4)^{10}=3,145,728[/tex]

For Ben:

Day 3:

[tex]f(3)=2(3)^3=54[/tex]

Day 10:

[tex]f(10)=2(3)^{10}=118,098[/tex]

And for Carter:

Day 3:

[tex]f(3)=10(2)^3=80[/tex]

Day 10:

[tex]f(10)=10(2)^{10}=10,240[/tex]

5)

Amber's new graph of:

[tex]f(x)=3(4)^x+45[/tex]

will be a shifted version of her original graph. The new graph will be shifted upwards by 45 units. However, since the 45 is not affected by the x in any way, the change will be minuscule. For instance, her number of shares on day 10 of the old graph is 3,145,728. Even with the additional 45, it will just be: 3,145,773. With enough days, the additional number becomes trivial.

6)

On the 10th day, Amber's post was shared almost 3 million times, while Ben's was shared "only" 118,098 times and Carter's with 10,240. Undoubtedly, Amber's post was the fastest.

7)

If you want to most shares as possible, choose Amber with fewer friends initially but more shares. This is because the exponential potential of a number even just a bit higher is insane. For instance, 3^10 (Ben's rate at 10th day) is only 59,049 while Amber's rate will be 4^10 which is 1,048,576. Amber's number is almost 18 times higher than Ben's. Even if Ben's initial number was say 1,000 or even 1,000,000, Amber would catch up rather quickly. Therefore, the rate is the quintessential part of an exponential growth function.

$ 3051

Step-by-step explanation:

Original cost = $ 1000

Marked up Price = Original cost + 170% of 1000

                            = 1000 + 1.7 * 1000

                            = 1000 + 1700

                            = $ 2700

Sales tax = 13% of 2700

               = 0.13 * 2700

               = 351

Total cost paid by Bernie = 2700 + 351 = $ 3051

Step-by-step explanation:

[tex]m +5=-m-2-5m+7[/tex]

Adding m and 5m to both sides of the equation.

[tex]m +5+m+5m= -m-2-5m+7+m+5m[/tex]

Subtracting 5 from both sides of the equation.

[tex]m +5+m+5m-5=-2+7-5[/tex]

Combining like terms and simplifying.

[tex]7m=0[/tex]

Dividing both sides of the equation by 7.

[tex]m=0[/tex]

Answer:

m + 5 = - m - 2 -5m + 7

m + 5 = -m - 5m - 2 + 7

Answer:

18 square units.

Step-by-step explanation:

Area of the triangle = ½*AB*CD

First of all, find the length of AB and CD using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

A(-6, 2) => (x1, y1)

B(3, 2) => (x2, y2)

[tex] AB = \sqrt{(3 -(-6))^2 + (2 - 2)^2} [/tex]

[tex] AB = \sqrt{(9)^2 + (0)^2} = \sqrt{81} = 9 [/tex]

[tex] CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

C(-2, 6) => (x1, y1)

D(-2, 2) => (x2, y2)

[tex] CD = \sqrt{(-2 -(-2))^2 + (2 - 6)^2} [/tex]

[tex] CD = \sqrt{(0)^2 + (-4)^2} = \sqrt{16} = 4 [/tex]

AB = 9

CD = 4

Area of rectangle = ½*AB*CD = ½*9*4 = 9*2 = 18 square units.

Answer:

The reciprocal of n must be less than 10.

Step-by-step explanation:

It can be inferred from the question given that n is not a negative number.

But,

[tex](n)^{2}[/tex] < [tex]\frac{1}{100}[/tex]

Find the square root of both sides,

n < [tex]\sqrt{\frac{1}{100} }[/tex]

⇒ n < [tex]\frac{1}{10}[/tex]

n < 0.1

The reciprocal of n can be estimated as;

[tex](n)^{-1}[/tex] < [tex](\frac{1}{10}) ^{-1}[/tex]

[tex]\frac{1}{n}[/tex] < 10

The reciprocal of n is less than 10.

Divide both sides by 36.8

We have the answer as

Answer:

The number a would be 7 which is 40% more than five more than a number a.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given the number that is 40% more than five more than a number a.

We need to find the unknown number a.

So, 40 % = 0.4

Let find the first part that is; "the number that is 40% more than five"

5 × 0.4 = 2

Now, five more than a number a.

2 + 5 = a

a = 7

Therefore, the number a would be 7 which is 40% more than five more than a number a.
