A circle is a shape formed by all points on a plane that are at a fixed distance from the center. It is the curve sketched out by a point moving in a plane such that its distance from a particular point remains constant. The radius is the distance between any point on a circle and the center. The radius must usually be a positive integer. Degenerate case is a circle with r=0. Except when otherwise specified, this article is about circles in Euclidean geometry, and specifically the Euclidean plane.

The total number of tongue depressors and Band-Aids are 56 and 128 respectively.

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given that, a medic's bag contains individually wrapped tongue depressors (each costing 4 cents) and Band-Aids (each costing 8 cents). If the materials are worth $12.48 and there are 184 individual packages in total,

Let the number of wrapped tongue depressors be w and that of Band-Aids be b,

Therefore,

w+b= 184

0.04w+0.08b = 12.48

w+2b = 312

On solving the equation, by elimination method, we get,

b = 128

Therefore, w+128 = 184

w = 56

Hence, the total number of tongue depressors and Band-Aids are 56 and 128 respectively.

The equation of the line is y = (-2/3)x + 8/3

What is a perpendicular line?

Two geometric objects are perpendicular in simple geometry if they intersect at a right angle. The perpendicular line can be used to graphically depict the condition of perpendicularity. It can be defined between any pair of lines, any pair of planes, or any pair of lines and planes.

The slope-intercept form of a line is written in the form:

y = mx + b

where:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Here, We have

y= 3/2x + 1/2 that passes through the point (-2,4)​

But we do not know the value of b.

We can do this by substituting the point(-2,4), into the equation and we get

y = mx + b

4 = (-2/3)(-2) + b

b = 8/3

Now that you know all your values, rewrite the equation in slope-intercept form:

y = (-2/3)x + 8/3

Hence, the equation of the line is y = (-2/3)x + 8/3

Answer:

It's an example of the distributive property

The equation of the line is will be y = -2x + 4.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Calculate the slope of the line,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -2 - 0) / ( 2 - 1) = -2

The y-intercept will be calculated as,

y = mx + c

0 = -2 x 2 + c

c = 4

The equation of the line will be,

y = mx + c

y = -2x + 4

Therefore, the equation of the line will be y = -2x + 4.

Answer:

x = -2.25

Step-by-step explanation:

To solve this we want to put the x alone on one side

Then by subtracting 6x from both sides

2x - 5 - 6x = 6x + 4 - 6x

- 4x - 5 =4

add 5 for both sides

- 4x - 5 + 5 = 4 + 5

- 4x = 9

Divide both sides by - 4

Then x = 9 / -4 = -2.25

So you only forget the negative sign

Glad to Help

Answer: x= - 9/4 or -2.25

Step-by-step explanation:

2x - 5 = 6x + 4(subtract 4 from the right side to move to the left side and subtract 2x from left side to move to right side)

-4 - 5 = 6x - 2x (now subtract these numbers as they have the same components)

-9 = 4x  (divide by 4 to get X alone)

-9/4 = x

The correct option regarding the proportional relationships for the costs of the Peanut Brittle and for the Almond Bark are given as follows:

Almond bark costs $0.25 more per ounce than peanut brittle.

A proportional relationship is a special case of a linear function, with slope k and intercept 0, hence the output variable y is obtained with the multiplication of the input variable x and the slope k, as follows:

y = kx.

The Peanut Brittle graph goes through the point (10, 10), hence the constant, which is the price per candy, is obtained as follows:

10k = 10

k = 10/10

k = 1.

For Almond Bark, the price per candy is obtained as follows, from the table:

4k = 5

k = 5/4

k = 1.25.

Using the given exponential function, it is found that:

a) The number of mosquitoes in the container after 5 days is of: 346.

b) The number of days until the container reaches the maximum capacity is of: 10 days.

The exponential function that models this problem is presented as follows:

P(t) = 24(4)^(0.385t).

Hence, after five days, the number of mosquitoes is of:

P(5) = 24(4)^(0.385 x 5) = 346 mosquitoes.

The number of days that it takes for the container to reach it's maximum capacity of 5000 is obtained solving the exponential function with logarithms as follows:

[tex]5000 = 24(4)^{0.385t}[/tex]

[tex](4)^{0.385t} = \frac{5000}{24}[/tex]

[tex](4)^{0.385t} = 208.3[/tex]

[tex]\log{(4)^{0.385t}} = \log{208.3}[/tex]

Applying the power property of logarithms, we have that:

[tex]0.385t\log{4} = \log{208.3}[/tex]

[tex]t = \frac{\log{208.3}}{0.385\log{4}}[/tex]

t = 10 days.

A. Yes, the data justifies a function because there is no repeating x values.

B. The relation f(x) = 2x + 13 has a greater value at x = 7

C. The value of x when f(x) = 75 is; 31

A) The general formula for equation of a line in slope intercept form is;

y = mx + b

where;

m is slope

b is y-intercept

Slope is;

m = (y₂ - y₁)/(x₂ - x₁)

m = (5 - 2)/(6 - 5)

m = 3

Let us test the first coordinate;

2 = 3(5) + b

2 = 15 + b

2 - 15 = b

-13 = b

so the equation is : y = 3x - 13

B) When x = 7, we have;

y = 3(7) - 13

y = 21 - 13

y = 8

Let us now test for when  f(x) = 2x + 13 to get;

f(x) = 2x + 13, when x = 7

f(7) = 2(7) + 13

f(7) = 14 + 13

f(7) = 27

the function has a greater value for f(x) = 2x + 13

C. f(x) = 2x + 13

when f(x) = 75

Thus;

75 = 2x + 13
