find the area and perimeter of a nonagon, inscribed in a circle, with radius 4 inches​

Answer:

9[tex]\sqrt{2}[/tex]/2

Step-by-step explanation:

Since this is a right triangle designated by the square box in the right side, we know 2 of the angles. 45 and 90. Add these 2 angles and subract them from 180 which turns out to be 45.

We can use the law of sines to solve.

sin90/9 = sin45/x

x = 9sin45 = 6.36 = 9[tex]\sqrt{2}[/tex]/2

The graph of the given linear equation, y = 1/2x + 1 (-x+2y=2), is given in the diagram attached below.

The graph of a linear equation is a straight line graph, and it is represented, in slope-intercept form as, y = mx + b, where m is the slope and b is the y-intercept of the graph.

Given the linear equation, -x+2y=2, rewrite in slope-intercept form:

-x+2y=2

2y = x + 2

y = x/2 + 2/2

y = 1/2x + 1

Thus, the graph of the linear equation is drawn as shown in the image attached below.

Answer:

a) V/2 ; b) V/4

Step-by-step explanation:

a) V = πR²h

If h --> h/2 the new volume V' = πR²h/2 = V / 2

b) πR²h

If D --> D/2 then R --> R/2 and the new volume V" = π(R/2)²h = π(R)²h/4 = V/4

The angle of inscribed polygon m∠MNT from the triangle ABC is 45°

An inscribed polygon is a polygon whose vertices lie on the circle and the circle inscribing the polygon is known to be a circumscribed circle. But let's not forget that the circle is also inscribed in another right-angle triangle.

However, using the inscribed right angle theorem:

Supposed that a right triangle is inscribed in a circle;

From the given image, line MN is the diameter of the circle since that is the only diameter in the circle.

We know that the sum of angles in a triangle is 180°. So, if ∠T = 90°, ∠N and ∠M = x

i.e.

90° + x + x = 180°

90° + 2x = 180°

2x = 180° - 90°

2x = 90°

x = 90°

x = 45°

Therefore, we can conclude that angle m∠MNT = 45°

The value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.

A limit is a value at which a function approaches the output for the given values in mathematics. Limits are used to determine integrals, derivatives, and continuity in calculus and mathematics.

We have a graph of a function:

For [tex]\lim_{x \to -1^{-1}} f(x)[/tex]

As we can see x approaches -1 and it is a left-hand limit.

[tex]\lim_{x \to -1^{-1}} f(x) = 3[/tex]

For [tex]\lim_{x \to -1^{+1}} f(x)[/tex]

The x approaches the +1 and it is the right-hand limit.

[tex]\lim_{x \to -1^{+1}} f(x) = -1[/tex]

For [tex]\lim_{x \to -1} f(x)[/tex]

Since the left hand and right-hand limits are not the same,

[tex]\lim_{x \to -1^{+1}} f(x)[/tex]  = does not exist

From the graph:

f(-1) = 3

Similarly, we can find further values of the limits and functions value:

[tex]\lim_{x \to 2^{-1}} f(x) = 1[/tex]

[tex]\lim_{x \to 2^{+1}} f(x) = 2[/tex]

For [tex]\lim_{x \to 2^{}} f(x)[/tex]

Since the left hand and right-hand limits are not the same,

[tex]\lim_{x \to 2^{}} f(x)[/tex] = does not exist

f(2) = 2

[tex]\lim_{x \to -\infty} f(x) = +\infty[/tex]

[tex]\lim_{x \to +\infty} f(x) = -\infty[/tex]

There are three conditions a graph must follow:

1) function value defined at any given point.

2) left-hand limit and right-hand limit must be equal

3) function value at the point and limit value at the same point must be the same.

In the given function the graph doesn't follow these conditions and its jump continuity.

Thus, the value of limits and function values for a, b, c, d, e, f, g, h, i, and j are 3, -1, does not exist, 3, 1, 2, does not exist, 2 +∞, and -∞ and doesn't follow continuity conditions and its jump continuity.

Answer:

214 square inch is the area of the figure

Answer:

21.6 m long

Step-by-step explanation:

To do this, we find the scale factor of the fencepost and the shadow.

3/1.8 = 1.66666667

So, we know that when we take the original length and multiply it, we get the new one, so:

1.666666667 * x = 36

x being the original length. Now, we divide both sides by 1.66666667 to get x alone and find the original length.

x = 21.6

To double check, we can take the scale factor and multiply it by the original to get the shadow.

21.6 * 1.666666667 = 36

It is correct

Answer: 1

Step-by-step explanation:

We can start by dividing both sides by 5. This gives us

[tex]6 + s = 7[/tex]

Subtracting 6 from both sides gives us

[tex]s = 7-6=1[/tex]

To check, we can put 1 back in the equation:

[tex]5(6+1) = 35[/tex]

[tex]5(7) = 35[/tex]

Since 5 * 7 is 35, 1 is the answer.

The logarithmic function is the inverse of the exponential function

The logarithmic equivalent of the exponential function is log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)

The exponential function is given as:

12^3=x^4 y^3 z^6

Take the logarithm of both sides

log(12^3) =log(x^4 y^3 z^6)

Apply the product rule of logarithm

log(12^3) =log(x^4) + log(y^3) + log(z^6)

Apply the power rule of logarithm

3log(12) = 4log(x) + 3log(y) + 6log(z)

Divide through by 3

log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)

Hence, the logarithmic equivalent of the exponential function is log(12) = [tex]\frac 43[/tex]log(x) + log(y) + 2log(z)

by looking at the point you can see what has a slope.

it is also a decreasing slope

the value of x + x(x^x) when x = 2.

x + x(x^x)

by putting the value of x = 2 in the above expression we get:

2 + 2(2^2)

= 2 + 2(2 × 2)

= 2 + 2(4)

= 2 + 8

= 10

therefore, the value of x + x(x^x) when x = 2 is 10.
