Answer:

A = 3[tex]r^{2}[/tex]

Step-by-step explanation:

r = [tex]\sqrt{\frac{A}{3} }[/tex]

r = [tex](\frac{A}{3})^{1/2}[/tex]

square both sides:

[tex]r^{2}[/tex] = [tex]\frac{A}{3}[/tex]

multiply 3 to both sides:

3[tex]r^{2}[/tex]  = A

Answer:

[tex] a= 3r {}^{2} [/tex]

[tex] \sqrt{ \frac{a}{3} } = r \\ \frac{1}{3a} = r {}^{2} \\ \frac{1}{3a} \frac{1}{3} = r {}^{2} \frac{1}{3} \\ a = 3r {}^{2} [/tex]

Answer:

113.04

Step-by-step explanation:

Since the diameter of a circle is twice the radius, the radius of this circle must be 12/2=6ft. Using the area formula:

[tex]A=\pi r^2 =3.14 \cdot 6^2=113.04 \text{ ft}^2[/tex]

Hope this helps!

Answer:

113.04

Step-by-step explanation:

area = (pi)r^2

r = radius = diameter/2

r = 12 ft/2 = 6 ft

area = 3.14 * (6 ft)^2

area = 3.14 * 36 ft^2

area = 113.04 ft^2

Answer:

1 pound

Step-by-step explanation:

Given the cost function of two domestic courier services.

We want to determine the weight (x) at which the costs (y) will be the same.

Since y=4x+1 and y=3x+2, then:

4x+1=3x+2

4x-3x=2-1

x=1 pound

When the weight of the parcel is 1 pound, the total cost of the parcel will be the same for the two domestic courier.

Answer:

  $15.30

Step-by-step explanation:

The formula for the account balance with continuous compounding is ...

  A = Pe^(rt)

For the given values, this is ...

  A = $3000·e^(0.05·10)

  A ≈ $4946.16 . . . . balance with continuous compounding

__

The amount with quarterly compounding is ...

  A = P(1 +r/n)^(nt)

  A = $3000(1 +.05/4)^(4·10)

  A ≈ $4930.86 . . . . balance with quarterly compounding

__

The difference is ...

  $4946.16 -4930.86 = $15.30

The continuously compounded account would earn $15.30 more in 10 years.

Answer:

Step-by-step explanation:

Let’s call the teams A B C D

A will play B C D = 3 matches

B will play only C and D as it already played A, making 2 matches

C will play D, making 1 match

D has already played all

Total number of matches is thus 3 + 2 + 1 = 6 matches

Answer: A 6 hours 15 minutes

Step-by-step explanation:

Time = Distance / Speed

Time = 750 / 120

Time = 6.25

Answer:

A. 6 hours and 15 minutes

Step-by-step explanation:

=> 120 miles = 1 hour

=> 1 mile = 1/120 hour

Multiplying both sides by 750

=> 750 miles =  hours

=> 750 miles = 6.25 hours

=> 750 miles = 6 hours 15 minutes

Start by setting up your two sets of parenthses.

X² breaks down into x and x.

What we are looking for is factors of the constant term

that add to the coefficient of the middle term.

The question is, what is the coefficient of the middle term

in this problem if there is nothing written in front of the x.

Well if there is nothing written there,

the coefficient is understood to be 1.

So what we are looking for are factors of -12 that add to -1.

Factors of -12

+12 · -1

-12 · +1

+6 · -2

-6 · +2

+4 · -3

-4 · + 3

We can see that -4 and +3 add to -1.

So they go in the second position of each binomial.

This gives us (x - 4)(x + 3) as our answer.

Answer: The largest angle formed during his trip is at the mall between his home and the library.

Step-by-step explanation:

Hi, since the situation forms a right triangle (see image attached) the angle formed between his home and the library is 90°.

The sum of the interior angles of a right triangle is 180°, and the right angle (90°)is the largest angle formed.

So, the largest angle formed during his trip is at the mall between his home and the library.

Graphing Linear Inequalities

This is a graph of a linear inequality:

linear inequality y <= x +2

The inequality y ≤ x + 2

You can see the y = x + 2 line, and the shaded area is where y is less than or equal to x + 2

Linear Inequality

A Linear Inequality is like a Linear Equation (such as y = 2x+1) ...

... but it will have an Inequality like <, >, ≤, or ≥ instead of an =.

How to Graph a Linear Inequality

First, graph the "equals" line, then shade in the correct area.

There are three steps:

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥)

or below the line for a "less than" (y< or y≤).

Let us try some examples:

Example: y≤2x-1

1. The inequality already has "y" on the left and everything else on the right, so no need to rearrange

2. Plot y=2x-1 (as a solid line because y≤ includes equal to)

Answer:

180°- 3α

Step-by-step explanation:

By angle sum postulate of a triangle.

[tex] m \angle \: A+ m \angle \: B + m \angle \: C = 180 \degree \\ \alpha + 2 \alpha + m \angle \: C = 180 \degree \\ 3 \alpha + m \angle \: C = 180 \degree \\ \huge \red{ \boxed{\angle \: C = 180 \degree - 3 \alpha}} \\ [/tex]

In a triangle [tex]ABC[/tex] the measure of angle [tex]C[/tex] is equals to [tex](180 - 3\alpha )\°[/tex].

" Triangle is defined as the two dimensional geometrical shape with three sides , three vertices and three angles enclosed in it.Sum of all the interior angles in a triangle is equals to [tex]180\°[/tex]. "

According to the question,

In a triangle [tex]ABC[/tex],

Given measure of angles,

[tex]m\angle A = \alpha \\\\m\angle B = 2\alpha[/tex]

Sum of all the interior angles in a triangle is equals to [tex]180\°[/tex].

Therefore,

[tex]m\angle A + m\angle B + m\angle C = 180\°[/tex]                               ________[tex](1)[/tex]

Substitute the value of  [tex]m\angle A , m\angle B[/tex]  in [tex](1)[/tex]  we get,

[tex]\alpha + 2 \alpha + m \angle C = 180\°\\\\\implies 3\alpha + m \angle C = 180\°\\\\\implies m \angle C = 180\°- 3\alpha[/tex]

Hence , in a triangle [tex]ABC[/tex] the measure of angle [tex]C[/tex] is equals to  [tex](180 - 3\alpha )\°[/tex].

A: Tis the melodious hue of beauty thrown  .

Explanation:

An appeal to the sense of hearing and sight will be something that presents an act that gives the readers a sense of the sounds in the writing. While an appeal to the sense of sight will present an image or a form of the picture to the readers. These types of sense appeals are used by writers to engage their readers' interest and keep them hooked.

In Percy Bysshe Shelly's poem "On the Medusa of Leonardo Da Vinci in the Florentine Gallery", the poet talks about the goddess Medusa but most importantly talks about the painting of "Medusa" by Da Vinci. The poem structured in the iambic pentameter scheme presents an image of Medusa and also how she was depicted by Da Vinci in his work. Out of the given options from the second stanza of the poem, the line that appeals to the sense of hearing and sight is "Tis the melodious (hearing/ sound) hue of beauty thrown (sight)".

Thus, the correct answer is option A.

Answer:

The graph that best fits this model of profit and price per unit is attached to this solution.

Step-by-step explanation:

A couple of graphs are missing from the question. According to the full question as obtained online, there are a number of graph options, and we are expected to pick the best option. I would not add all the other graphs to limit the chances of deletion due to violating community guidelines.

The function is to model the profits of a new pet-monitoring system, so, if the profits are y and x is the price per unit, y = f(x)

The profits vary as the price per unit varies, there is no profit made until the price reaches

$95 per unit, a maximum profit at a price of $140 per unit, and no profit at a price over $185 per unit.

This description of the curve shows that y is negative at values of x less than $95, then the profits increase when x varies between $95 and $140. The profits reach a maximum at $140 and then the profits start to decline as x increases again, the profits go to 0 at x = $185.

This description shows that the function is a quadratic function with a graph that is n-shaped, peaking at x=185 and the graph crosses the x-axis at x=95 and x=185.

The most fitting graph for this model is attached to this solution provided.

From the graph, all the descriptions above are evident.

The coordinates of that center of a circle with endpoints of its diameter at a(8,-4) and b(-3,2) is (2.5, -1)

The standard equation of a circle is:

(x - a)² + (y - b)² = r²

where (a, b) is the center of the circle and r is the radius of the circle.

Given the diameter endpoints at a(8,-4) and b(-3,2), let (x, y) be the center of the circle, hence:

[tex]x=\frac{8-3}{2} =2.5\\\\y=\frac{-4+2}{2}=-1[/tex]

Hence the center of the circle is at (2.5, -1)

The coordinates of that center of a circle with endpoints of its diameter at a(8,-4) and b(-3,2) is (2.5, -1)
