The area of the regular octogon is 196.15 square inches.

For a regular octogon with apothem A and side length L, the area is given by:

area =(2*A*L) * (1 + √2)

Here we know that:

A = 7in

L = 5.8 in

Replacing these values in the area for the formula, we will get the area:

area = (2*7in*5.8in) * (1 + √2)

area = 196.15 in²

Answer:D

Step-by-step explanation:

Answer:

x = 45.6

Step-by-step explanation:

NOTE: Please double-check my answer.

To find x, I used Sine Law.

\(\frac{x + 5}{sin65}\) = \(\frac{x}{sin40}\)

(x+5)sin40 = xsin65

xsin40+ 5sin40 = xsin65

xsin40 - xsin65 = -5sin40

x(sin40 - sin65) = -5sin40    (I factored out the "x")

x = \(\frac{-5sin40}{sin40 - sin65}\)

x = \(\frac{-3.725565802}{0.74511316 - 0.826828679}\)

x = 45.6

Answer:

The triangle will translate along the arrow and reach the head of the arrow.

Step-by-step explanation:

Translation is a category of motion in which one body moves along towards a particular direction and reaches a particular point.

In translation, the rotational motion is not present. Also, the translational motion is a one dimensional motion.

In the given figure, the triangle is present at the tail of the arrow.

The arrow depicts the direction of the translational motion.

So, the triangle will reach the end of the arrow as shown in the picture present in the attachment.

Let's draw the situation and see what is the information that we have:

So we have to find the distance x which is the distance that the boat has to travel in order to be located directly above the fish. For this let's use Cosine which is cosine=Adjancent/Hypotenuse

The boat has to travel 136 yards on the surface of the ocean to be located directly above the fish.

In conclusion Rounding to four decimal places, we get:

f(t) = 9100e²(0.1398t)

How to solve?

To write the function F(t) = 9100(1.15)²t in the form f(t) = ae²(kt), we need to first take the natural logarithm of both sides:

ln(F(t)) = ln(9100(1.15)²t)

ln(F(t)) = ln(9100) + ln(1.15²t)

ln(F(t)) = ln(9100) + t × ln(1.15)

Now, we have the form ln(F(t)) = ln(a) + kt, where k = ln(1.15) and a = 9100. We can exponentiate both sides of this equation to get:

F(t) = e²(ln(a) + kt)

F(t) = e²ln(a) × e²(kt)

F(t) = a × e²(kt)

Substituting the values of a and k, we get:

F(t) = 9100 × e²(0.1398t)

Rounding to four decimal places, we get:

f(t) = 9100e²(0.1398t)

The most appropriate statement is that C. The shaded area represent both 2/3 and 6/9 of the whole shape.

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Given a square.

This square is divided in to 9 equal sized squares, with 3 rows and 3 columns.

Out of the 9 equal sized squares, 6 squares are shaded.

We can write the fraction of shaded squares to total number of squares as 6/9.

In the same way, we have in the question that, 6 squares which are shaded is the squares in the first two columns, where each column has three squares.

So we can say that, out of 3 equal sized columns, two columns are shaded.

Fraction of shaded columns to total columns is 2/3.

So 2/3 = 6/9.

Hence shaded area represent both 2/3 and 6/9 of the whole shape.

As the sample size rises, the sample distribution approaches a normal distribution.

The sample distribution approaches a normal distribution as the sample size grows. The sampling distribution's mean equals the population's mean if the number of consecutive samples is "infinite".

The Gaussian distribution is the official name for the normal distribution. However, the word "normal" was coined in the nineteenth century after a scientific inquiry revealed that numerous natural events appeared to "deviate from normal" from their typical values.

In his 1889 work Natural Inheritance, naturalist Sir Francis Galton popularized the notion of normal variability as the standard curve.

It deals with qualities or attributes that cannot be expressed numerically. In this case, the names of TV shows are characteristics that describe the nature of the data. Quantitative data, on the other hand, is numerical data that can be measured and expressed in numbers. A parameter is a measurable factor or variable that can be used to define a system, while statistics is a branch of mathematics that deals with data collection, analysis, and interpretation.

The equation of the line passing through P(0, 0) perpendicular to y = -9x - 1 will be  \(y = \frac{1}{9}x\)

The given question states that the line passes through the point P(0, 0) perpendicular to the line y = -9x - 1. We have to find out the equation of the line. We have to find the equation in slope-intercept form.

We know the slope intercept is: y = mx + b

Also, given the perpendicular line has slope m₂ = -9 according to slope-intercept form. And we know that perpendicular lines have a slope that is equal to the negative reciprocal.

So, the Slope of the line m₁ = Negative reciprocal of the slope of the perpendicular line.

=>  \(m_{1} = -\frac{1}{m_{2} }\)

=> \(m_{1} = -\frac{1}{(-9)}\)

=> \(m_{1} = \frac{1}{9 }\)

We get the slope \(m_{1} = \frac{1}{9 }\). Also, it is given that the line passes through (0, 0) so the y-intercept b = 0. Putting these values in slope-intercept form, we get:

=> y = mx + b

=> \(y = \frac{1}{9} x\)

Hence, the equation of the line is \(y = \frac{1}{9} x\)

The total number of ways/ permutation that A occupies first position is 24 ,  A occupies the first position, and B the second is 6 and a appears before b is 10 ways.

What is permutation ?

Permutation is a meeting of objects in an exceedingly definite order. The members or components of sets square measure organized here in an exceedingly sequence or linear order.

Main body:

A) a occupies the first position-

As A is first, and arrange the remaining letters.  letters (B,C,D,E,F) can be arranged as-

4*3*2*1 = 24 ways

B) a occupies the first position, and b the second

As A is first and b is just after it , there are 5 position out of which 2 are taken by A, B in order , so number of ways they can be arranged is

3*2*1 = 6 ways

C) a appears before b

in this part there is no  condition that a appears just before b , so b can be places anywhere after A.

after fixing A at first place , B can be placed at 4 places.

after fixing A at 2nd place , B can be placed at 3 places.

after fixing A at 3rd place , B can be placed at 2 places.

after fixing A at 4th  place , B can be placed at 1 places.

total ways = 4+3+2+1 = 10
