The center of the circle is (-1.5, -2) and the radius is 3.205.

To find the center and radius of the circle, we can use the formula for the distance between two points in a coordinate plane. The two points given are (-3, -4) and the origin (0, 0), which represents the diameter of the circle. The center of the circle is the midpoint of the diameter, which can be found by taking the average of the x-coordinates and the y-coordinates. So, the center is ( (-3+0)/2 , (-4+0)/2 ) = (-1.5, -2). The radius of the circle is half the length of the diameter, which can be found using the distance formula as the distance between the center and one of the endpoints of the diameter. So, the radius is the distance between (-1.5, -2) and (-3, -4), which is √((-3-(-1.5))² + (-4-(-2))²) = √(2.5² + 2²) = √(6.25 + 4) = √10.25 = 3.205.

Second

61.72+9.258= 70.978

Answer:

Angle B: 135 degrees

Angle A: 60 degrees

Angle C:  75 degrees

Step-by-step explanation:

Angle B is 135 degrees

We have the complement of angle B, which is the lowest left corner of the triangle and it says 45 degrees.

So, B = 180 - 45 = 135 degrees

Angle A.

The lines crossing form 2 pair of identical angles from their tip... The exterior angle is 60 degrees, so the interior angle A is also 60 degrees.

Angle C.

Just like for angle B, we get angle C by subtracting its complement:

C = 180 - 105 = 75 degrees.

We can also validate by calculating the sum of the interior angles of the triangle: 45 + 60 + 75 = 180, which is perfect.

Answer: Surface area is equal to 200[tex]cm^{2}[/tex]

Volume is equal to 333.33[tex]cm^{3}[/tex]

Step-by-step explanation:

First, let's do surface area.

The surface area of a pyramid is equal to 1/2(perimeter of base)(lateral height) + area of the base

The perimeter of the base is 10(4) = 40; as the base is a square with a side length of 10.

The lateral height is given as 5 cm.

The area of the base is 10(10) = 100.

We can plug those numbers into the equation to get 1/2(40)(5) + 100, which comes out to be 200[tex]cm^{2}[/tex].

Now for volume.

The volume of a pyramid is equal to 1/3(area of the base)(height).

We already have the area of the base, which is 100.

The height is given as 10 cm.

Plugging those numbers into the equation, we get 1/3(100)(10), which is 1000/3 or about 333.33[tex]cm^{3}[/tex].

Answer:

40°

Step-by-step explanation:

1. Shape of a nonagon: 9 (root non-)

2. Total exterior angle: 360° (constant for all polygons)

3. Given that this polygon is regular, the one exterior angle of an nonagon is 360°/9 = 40°.

Answer:

Step-by-step explanation:

An exterior angle and an interior angle are supplementary angles.

Two Angles are Supplementary when they add up to 180°.

Therefore the measure of exterior angle is equal to different between 180° and an interior angle.

Method 1:

You can use the formula of the measure of interior angle of the regular polygon with n-sides:

[tex]\alpha=\dfrac{180^o(n-2)}{n}[/tex]

We have a nonagon. Therefore n = 9. Substitute:

[tex]\alpha=\dfrac{180^o(9-2)}{9}=(20^o)(7)=140^o[/tex]

[tex]180^o-140^o=40^o[/tex]

Method 2:

Look at the picture.

[tex]\alpha=\dfrac{360^o}{9}=40^o[/tex]

[tex]2\beta[/tex] - it's an interior angle

We know: The sum of measures of these three angles of any triangle is equal to 180°.

Therefore:

[tex]\alpha+2\beta=180^o\to2\beta=180^o-\alpha[/tex]

Substitute:

[tex]2\beta=180^o-40^o=140^o[/tex]

[tex]\theta[/tex] - it's a exterior angle

[tex]2\beta+\theta=180^o\to\theta=180^o-2\beta[/tex]

substitute:

[tex]\theta=180^o-140^o=40^o[/tex]

Answer:

1+6i

Step-by-step explanation:

Given:

f(x)=x^4 - 2x^3 + 38x^2 - 2 + 37

zero of f(x) = 1-6i

another zero of function = ?

Conjugate Zero theorem:

As per conjugate zero theorem, if a function f(x) has real coefficients and one of zero is a complex number then the conjugate of that complex number will also be a zero of that function i.e. complex zeroes will occur in complex conjugate pairs.

conjugate of 1-6i is 1+6i

hence another zero of f(x) will be 1+6i !

The inverse of the function [tex]y = 3x^5 - 4[/tex] is [tex]y = \sqrt[5]{\frac{x + 4}{3}}[/tex]

How to determine the inverse of the function

From the question, we have the following parameters that can be used in our computation:

[tex]y = 3x^5 - 4[/tex]

Swap the variabls x and y

So, we have

[tex]x = 3y^5 - 4[/tex]

Add 4 to both sides

This gives

[tex]3y^5 = x + 4[/tex]

Divide through by 3

[tex]y^5 = \frac{x + 4}{3}[/tex]

Take the 5th root of both sides

[tex]y = \sqrt[5]{\frac{x + 4}{3}}[/tex]

hence, the inverse of the function is [tex]y = \sqrt[5]{\frac{x + 4}{3}}[/tex]

Equation: x/9 + 2 = 8

Solution: x = 54

Step-by-step explanation:

I'd imagine the question is asking "two more than the quotient of a number and 9 is 8." Let's break this down:

- two more than means we're going to be adding two to the following quantity in the sentence.

- the quotient of a number and 9 we can interpret as a division expression. We don't know what "a number is," so we can give it a label (I'll pick n), and we can now write it is x/9. Taken with that last bullet point, our expression becomes x/9 + 2.

- Finally, we're told that the result of this expression is 8, so we can write the compete equation as x/9 + 2 = 8.

Now, if we want to solve this:

We can start by subtracting 2 from either side, giving us

x/9 = 6

And multiplying either side by 9 gives us the solution

x = 54.

The correct matches are: Directrix y = -7.25 → Equation of Parabola: y + 7 = (x - 4)², Directrix y = 6.25 → Equation of Parabola: y - 6 = -(x - 1)², Directrix y = 17.25 → Equation of Parabola: y - 17 = -(x - 3)², Directrix y = 14.25 → Equation of Parabola: y - 14 = -(x - 3)².

To match the equations representing parabolas with their directrixes, it's essential to understand the standard form of a parabola's equation related to its axis of symmetry.

For a vertical parabola, the standard form is y = a(x - h)² + k, where the vertex is at (h, k) and the directrix is y = k - 1/(4a) for a parabola that opens upwards, or y = k + 1/(4a) for a parabola that opens downwards.

For a horizontal parabola, the standard form is x = a(y - k)² + h. In our case, all given equations are in the vertical form where x is squared.

Let's take each equation and find its directrix:

With the directrix found for each equation, the correct matches are:

$ 0.77 or 77 cents

because 77 out 100 is written in decimal form as .77

Hello there!

Answer:

Your answer would be $0.77

Step-by-step explanation:

The reason why $0.77 would be the correct answer is because that represents something that is lower than a dollar, more so you would know it as "cents."

When you look at the question, it says, "77/100 of a dollar." What that means is that there is 77 of a dollar, and a dollar is equivalent to one whole.

The denominator "100" represents a whole, so that means that there is 77 out of a whole.

When you know currencies, cents are lower than a whole, therefore would be represented as a decimal.

77/100 is equivalent to 0.77.

As a money amount, it would be $0.77.

$0.77 should be the CORRECT answer.

Notes/Explanations + answer in written form

Let's say that Halley's age now is:              x

That means that her age in 18 years is:      x + 18

It also means that her age 2 years ago is:   x - 2

In the question, we are told that when Halley is 18 years older than her current age,  she will be 5 times the age she was when she was 2 years younger than her current age

That means:

Halley's current age + 18 years = 5 times (Halley's current age - 2 years)

So we get this equation (which we solve to get the answer) :

x + 18 = 5 * (x -2)                      ( expand the brackets)

x + 18 = 5x - 10                          (subtract x from both sides)

18 = 4x - 10                                 (add 10 to both sides)

28 = 4x                                       (now divide both sides by 4)

7 = x

Therefore, Halley's current age is 7 years

Final answer:

To cover the wooden cylinder with carpet, Sandy needs to find the surface area of the cylinder and then cut out a piece of carpet that matches that area.

Explanation:

To cover the wooden cylinder with carpet, Sandy needs to find the surface area of the cylinder and then cut out a piece of carpet that matches that area. The surface area of a cylinder can be found using the formula: SA = 2πr(r+h), where r is the radius of the base and h is the height of the cylinder. In this case, the diameter of the cylinder is 1 ft, so the radius is 1/2 ft. The height of the cylinder is 4 ft. Plugging these values into the formula, we get: SA = 2π(1/2)(1/2 + 4) = 2π(1/2)(9/2) = 9π square ft.
