The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 2.17 square centimeters. The perimeter of the octagon is 48 centimeters. What is the length of each side of the octagon?

Answers

Answer:

The length of each side of the Octagon is 6 centimeters

Step-by-step explanation:

An Octagon is an 8 sided polygon

The perimeter of the octagon can be obtained by the addition of all the sides of the octagon

Since it is a regular octagon, it means that all the sides are of equal length

Mathematically, what this mean is that the perimeter of the Octagon is simply 8s

where s is the length of the side of the Octagon

Thus, mathematically, the length of each side of the Octagon will be 48/8 = 6 centimeters

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerted by the weight lifter?

Answers

Answer:

The force exerted by the weight lifter is 81.7 N.

Step-by-step explanation:

We can find the force exerted by the weight lifter using the definition of work:

[tex] W = F*d [/tex]    (1)

Where:

F: is the force

d: is the displacement

We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:

[tex] F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N [/tex]

Therefore, the force exerted by the weight lifter is 81.7 N.

whats the answer to (5² -4) ∙ 2 – 18

Answers

Answer:

Solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24

Step-by-step explanation:

We need to solve the equation [tex](5^2 -4) \cdot 2 -18[/tex]

We will solve using DMAS rule i.e first bracket will be solved, then multiplication and at the end subtraction will be done.

First we will solve the bracket

[tex](5^2 -4) \cdot 2 -18\\=(25-4) \cdot 2-18\\=21 \cdot 2-18[/tex]

Now multiply 21 by 2

[tex]=42-18[/tex]

Now subtract

[tex]=24[/tex]

So, solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24

True
Or
False

Answers

Answer:

           TRUE

Step-by-step explanation:

In arithmetic sequence the difference (d) between any pair of next and previous term is the same.

-7-23 = - 30

-37 - (-7) = -37+7 = - 30

-67 - (-37) = -67 +37 = - 30

d = -30

So this is  arithmetic sequence.

b=100 and c=100

Step-by-step explanation:

Because 100 is across a no value which is also 100 because they are the same and the b and c sides too so they both are 100

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex]100° + b = 180°[/tex]

Because they make straight line.

Also ;

[tex]100° + c = 180°[/tex]

Thus :

[tex]b = c[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex]100° + b = 180°[/tex]

Subtract sides 100°

[tex] - 100° + 100° + b = 180° - 100° \\ [/tex]

[tex]b = 80°[/tex]

So ,

[tex]b = c = 80°[/tex]

x²-4 / x²+9x+20 is greater than/equal to 0

Answers

Answer:

true

Step-by-step explanation:

x²-4/x²+9x+20 >=0

cross multiplying the equation we have,

(x²-4/x²+9x+20)*x²+9x+20 >= 0*x²+9x+20

= x²-4>=0

x²>=4

taking the square root of both sides, we have:

√x²>= √4

x >=2

In the rhombus, the measure of angle 1 = 18x, the measure of angle 2 = x + y, and the measure of angle 3 = 30z. Find the value of x + y + z. The diagram is not drawn to scale. ​

Answers

Answer:

A. 93

Step-by-step explanation:

Each angle is 90 degrees.

18x = 90

x=5

x + y = 90

5 + y = 90

y = 85

30z = 90

z = 3

5 + 85 + 3 = 93

Use the graphs of f and g to describe the transformation from the graph f to the graph g

Answers

Answer:

The graph of g is a VERTICAL translation 2 unit(s) UP of the graph of f

The graph f(x) is translated vertically upward by 2 units to g(x).

Given that,
To describe the transformation from graph f to graph g.

What is a graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.


Here,
f(x) = -2x
Now,
g(x) = f(x) + 2
g(x) = -2x + 2
Implies f(x) is increased by 2 or graph translated 2 units upwards.

Thus, the graph f(x) is translated vertically upward by 2 units to g(x).
