Find the area and perimeter. Please help!!!!!!!!!??

Answer:

[tex]k = 2[/tex]

Step-by-step explanation:

[tex]\textrm{P(blue \;bead)} = \dfrac{\textrm{Number of blue beads}}{\textrm{Total number of beads}}\\\\\textrm {Number of blue beads } = k\\\\\textrm{Total number of beads } = k + 4\\\\[/tex]

[tex]\textrm{P(blue \;bead)} = \dfrac{k}{k+4}\\\\[/tex]

[tex]\textrm{We are given this probability as } \dfrac{1}{3}\\\\\textrm{So,}\\\\\dfrac{k}{k+4} = \dfrac{1}{3}\\\\[/tex]

Cross-Multiplying this equation we get
[tex]k\cdot 3 = 1 \cdot (k + 4)\\\\\longrightarrow 3k = k + 4\\\\3k - k = 4\\\\2k = 4\\\\k = 2\\\\[/tex]

The slope of the linear equation perpendicular to:

x - 6y = 24

is a = -6.

A general line can be written in the slope-intercept form as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Particularly, two lines are perpendicular if the product between their slopes is equal to -1.

Here we want to find a line perpendicular to:

x - 6y = 24

First, we need to find the slope of this line.

x - 6y = 24

-6y = -x + 24

y = (-1/6)*-x - 24/6

y = (1/6)*x - 3

The slope is 1/6, then if the slope of the perpendicular line is a, the slope must be a solution of:

a*(1/6) = -1

a = -6

Answer:

a = 15 , b = [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

the equation of proportion is

y = kx ← k is the constant of proportion

to find k substitute x = 0.7, y = 2.1 , values from the table into the equation

2.1 = 0.7k ( divide both sides by 0.7 )

3 = k

y = 3x ← equation of proportionality

then using x = 5

On solving the provided question we can say that the Measure of complementary angles   ∠ZY is 40 degrees.

When the sum of the measurements of two angles is 90 degrees, they are said to be complimentary.For instance, the angles of 30 and 60 degrees are supplementary. A supplementary angle is two angles combined to make a 180 degree angle, while a supplemental angle is two angles combined to make a 90 degree angle. Two angles are referred to as complimentary if their total is 90 degrees. Alternatively said, a right angle is created by the complementary angles (90 degrees).

Since ∠ZS and ∠ZY are complementary,

∠ZY+∠ZS=45                                                                                       We also have another relation which says

∠ZS=2∠ZY -30

Substituting 2. in 1. gives

∠ZY+2∠ZY -30=90

3∠ZY=120

∠ZY=40

The company Sea Esta can elect a president, vice-president, secretary and treasurer in 495 different ways.

What is Combination in Mathematics?

In mathematics, a combination is a way of selecting a certain number of items from a larger set of items, without regard to the order in which the items are selected. It is a way to count the number of distinct subsets of a given size from a larger set.

The formula for combination is:

(n!) / (r! * (n-r)!)

The company Sea Esta has 12 members on its board of directors, and they need to elect a president, vice-president, secretary, and treasurer. The number of ways to elect these four positions is determined by using the formula of combination, which is:

Where n is the total number of options (in this case, the number of board members) and r is the number of positions to be filled (in this case, 4).

So, the number of ways to elect a president, vice-president, secretary, and treasurer is:

(12!) / (4! * (12-4)!) = (1211109) / (4321) = 495

Therefore, the company Sea Esta can elect a president, vice-president, secretary and treasurer in 495 different ways.

Next, divide this by the increments give:

81 / 75 = 1.08

Now, the increments were each 45 minutes, so multiply this by the product:

45 x 1.08 = 48.6

Part (a)

[tex]\lim_{h \to 0} \frac{(h-1)^5+1}{h} \\ \\ =\lim_{h \to 0} \frac{5(h-1)^4}{1} \\ \\ =\boxed{5}[/tex]

Part (b)

[tex]y+1=5(x+1) \\ \\ y+1=5x+5 \\ \\ \boxed{y=5x+4}[/tex]

Answer and explanation: The equation for the slope-intercept form is y=mx+b. M represents the slope and b is y-intercept/when x= 0.

We have to arrange the given equation into the form y=mx+b.

3x+2y=-14, We want to somehow isolate y.

2y=-14-3x, We can move all the terms that don't have y to the right

y=(-14-3x)/2, We can get rid of the 2 by dividing by 2 on both sides

y=-7-(3/2)x, We can distribute the division by 2 to both terms on the right

y=-(3/2)x-7, We can now just rearrange the terms

The equation is now in the form y=mx+b as -3/2 is m and -7 is b. Your answer to the first question is A.

For part B, we can use the equation for part A. We know m or the slope is -3/2 so our answer is also A.

Using Pythagoras theorem, the altitude a is √33.

The Pythagorean theorem, a cornerstone of Euclidean geometry, connects the side lengths of a right triangle via the straightforward formula a² + b² = c². Ancient scholars and architects from Babylon, Egypt, China, and India were aware of the connection.

While Pythagoras lived and wrote between 569 and 475 BCE, the work that bears his name first appeared on clay Babylonian tablets around 1800 BCE. Early Chinese scholars were also aware of the Pythagorean theorem, and it was mentioned in ancient Indian sacred texts that dealt with the construction of altars.

To solve a,

We can see a right triangle forming by those 3 squares

Lets take theirs sides as the base, altitude and hypotenuse

Hypotenuse = 7

Base = 4

Altitude = to find

Using Pythagoras theorem

[tex]a^2 + b^2 = c^2[/tex]

[tex]\Rightarrow a = \sqrt{c^2 - b^2 }[/tex]

[tex]\Rightarrow a = \sqrt{7^2 - 4^2 }[/tex]

The value of x and y in right angle triangle is  16√2 and 16

What is a Right Angle Triangle ?

A right triangle is a triangle having one right angle or two perpendicular sides. It is also referred to as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle. The relationship between the sides and various angles of the right triangle serves as the basis for trigonometry.

The Pythagorean theorem, often known as Pythagoras' theorem, in Euclidean geometry relates the three sides of a right triangle. This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

In the triangle 2 angles are 90° and 45° respectively.

The third angle is  = 180°+90°-45°=45°

The triangle is issosceles triangle

So the side which is not x is 16.

Now by using Pythagoras Theorem

x = √16^2+16^2 = 16√2

The value of x is 16√2

The value of y is y^2 + 16^2 = 16√2^2

y^2 = 512 - 256

y^2 = 256

y = 16

Let f be a function defined on all of that satisfies the additive condition is,

f: R → R is a continuous function such that:

[tex]f(x+y)[/tex] = [tex]f(x) + f(y)[/tex]    ∀  x , y ∈ R  (Equation-1)

Now, let us assume f(1)=k

Also,

f(0) = 0( Since, f(0)=f(0+0)

That is,

f(0)=f(0)+f(0)

By using property (1)

Also,

f(0)=2f(0)

That is,

2f(0)-f(0)=0

That is,

f(0)=0  )

Also,

f(2)=f(1+1)

That is,

f(2)=f(1)+f(1)         ( By using property (1) )

i.e.

f(2)=2f(1)

That is,

f(2)=2k

Similarly for any m ∈ N

f(m)=f(1+1+1+...+1)

That is,

f(m)=f(1)+f(1)+f(1)+ ....... +f(1) (m times)

That is,

f(m)=mf(1)

That is,

f(m) = [tex]mk[/tex]

Now,

f(1) = [tex]f(\frac{1}{n} +\frac{1}{n} +......\frac{1}{n} )[/tex]

f(1) = n [tex]f(\frac{1}{n} )[/tex]

f(1) = k

[tex]f(\frac{1}{n} )[/tex] = k * [tex]\frac{1}{n}[/tex]

Also,

when x∈ Q

Then,

[tex]f(\frac{p}{q})[/tex] = [tex]f(\frac{1}{q} )+ f(\frac{1}{q} )+ .....f(\frac{1}{q} )[/tex]

[tex]f(\frac{p}{q})[/tex] = p * [tex]f(\frac{1}{q} )[/tex]

[tex]f(\frac{p}{q})[/tex] = [tex]p\frac{k}{q}[/tex]

[tex]f(\frac{p}{q})[/tex] = [tex]k\frac{p}{q}[/tex]

So,

[tex]f(x) = kx[/tex] for all x belongs to Q

Now, as we know that:

Q is dense in R.

So Э x∈ Q' such that Э a seq < [tex]x_{n}[/tex] >  belonging to Q such that:

Now, we know that: Q'=R

Э α ∈ R

such that Э sequence [tex]a_{n}[/tex] such that:

[tex]a_{n}[/tex] belongs to Q,

[tex]a_{n}[/tex] ⇒ [tex]\alpha[/tex]

[tex]f(a_{n} )= ka_{n}[/tex]

( since [tex]a_{n}[/tex] belongs to Q )

Let f is continuous at x=α

k [tex]a_{n}[/tex] ⇒ [tex]f(\alpha )[/tex]

k [tex]a_{n}[/tex] ⇒ k [tex]\alpha[/tex]

This means that:

To calculate the average (mean) value of a function, you need to find the area under the curve of the function, divide it by the interval over which the function is defined, and then find the value of the function at the midpoint of the interval.

In this case, the function is 3t³ - t² and we need to find an interval to calculate the average (mean) value. A common interval used for this calculation is from 0 to 1.

The area under the curve of the function from 0 to 1 can be found by integrating the function from 0 to 1. However, to keep it simple, we can also use the definite integral of the function from 0 to 1, which is:

∫ (3t³ - t²) dt = 3t⁴/4 - t³/3 | from 0 to 1

= (3/4) - (1/3) = 1/4

So, the average (mean) value of the function 3t³ - t² over the interval 0 to 1 is: 1/4 ÷ 1 = 1/4

And the value of the function at the midpoint of the interval, which is 0.5, is: 3(0.5) ³ - (0.5) ² = 3/8 - 1/4 = -1/32

So, the average (mean) value of the function 3t³ - t² over the interval 0 to 1 is -1/32.
