In The Diagram Below P Is Circumscribed About Quadrilateral ABCD. What Is The Value Of X?

Answers

Answer 1

Answer:

(A) [tex]x=60^{\circ}[/tex]

Step-by-step explanation:

Given: It is given that the circle P is circumscribed about quadrilateral ABCD and ∠BCD=120°.

To find: The value of x

Solution: It is given that the circle P is circumscribed about quadrilateral ABCD and ∠BCD=120°.

Now, we know that the sum of opposite angles in a cyclic quadrilateral is 180°, therefore

[tex]{\angle}BAD+{\angle}BCD=180^{\circ}[/tex]

substituting the given values, we get

[tex]x+120^{\circ}=180^{\circ}[/tex]

[tex]x=60^{\circ}[/tex]

Thus, the value of x is 60°.

Hence, option A is correct.

what is 6(2y+8)-2(3y-2)

Answers

The answer is 6y + 52.

first, distribute.

6 • 2y = 12y

6 • 8 = 48

this would equal

12y + 48

then do the same for the other part

2 • 3y = 6y

2 • 2 = 4

this would equal

6y + 4

put them all into one.

12y + 48 - 6y + 4

combine the like terms..

12y - 6y = 6y

48 + 4 = 52

the final answer would be 6y + 52

Which equation represents a circle with a center at -3,-5 and a radius of 5

Answers

Answer: [tex](x+3)^2+(y+5)^2=25[/tex]

Step-by-step explanation:

The equation of the in center-radius form  is the shown below:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where the center is at the point (h,k) and r is the radius of the circle.

Based on the information given in the problem, the center of the circle is at the point (-3,-5) and a radius of the circle is 5, then,  you must substitute values into the equation shown above.

Therefore, you obtain the following equation:

[tex](x-(-3))^2+(y-(-5))^2=(5)^2[/tex]

If a cone has a surface area of 822.78cm^2 and a diameter of 18cm, find the slant height of the cone

Answers

Answer:

[tex]20.11\ cm[/tex]

Step-by-step explanation:

we know that

The surface area of the cone is equal to

[tex]SA=\pi r^{2}+\pi rl[/tex]

where

r is the radius

l is the slant height

In this problem we have

[tex]SA=822.78\ cm^{2}[/tex]

[tex]r=18/2=9\ cm[/tex] -----> the radius is half the diameter

substitute and solve for l

[tex]822.78=\pi (9)^{2}+\pi (9)l[/tex]

[tex]822.78=81\pi +9\pi l[/tex]

[tex]l=(822.78-81\pi)/9\pi[/tex]

[tex]l=(822.78-81(3.14))/9(3.14)=20.11\ cm[/tex]

The slant height of the cone is approximately 20.1154 cm.

[tex]\[ \text{Surface Area} = \pi r (l + r) \][/tex]

where r is the radius of the base of the cone, and l is the slant height of the cone.

Given that the diameter of the cone is 18 cm, we can find the radius r by dividing the diameter by 2:

[tex]\[ r = \frac{diameter}{2} = \frac{18 \text{ cm}}{2} = 9 \text{ cm} \][/tex]

Now we can substitute the values we know into the surface area formula:

[tex]\[ 822.78 \text{ cm}^2 = \pi \times 9 \text{ cm} \times (l + 9 \text{ cm}) \][/tex]

To find l, we need to solve for l in the equation:

[tex]\[ 822.78 \text{ cm}^2 = 9 \pi \text{ cm} \times (l + 9 \text{ cm}) \] \[ \frac{822.78 \text{ cm}^2}{9 \pi \text{ cm}} = l + 9 \text{ cm} \] \[ \frac{822.78}{9 \pi} = l + 9 \] \[ l = \frac{822.78}{9 \pi} - 9 \][/tex]

Now we calculate the value of l:

[tex]\[ l = \frac{822.78}{9 \times \pi} - 9 \] \[ l = \frac{822.78}{28.27433388} - 9 \] \[ l \approx 29.1154 - 9 \] \[ l \approx 20.1154 \text{ cm} \][/tex]

Answer:

tan

Step-by-step explanation:

                                                                (secx - 1)(secx + 1)

Remove parentheses                          = sec²x - 1

Use the identity: tan²x  + 1 = sec²x     = tan²x + 1 - 1

                                                             = tan²x

tan²x = (secx - 1)(secx + 1)

Answer:  The required answer is tan x.

Step-by-step explanation:  We are given to complete the following trigonometric identity :

[tex](\_\_\_\_\_)^2=(\sec x-1)(\sec x+1).[/tex]

We will be using the following identity from trigonometry to complete the given identity :

[tex]1+\tan^2\theta=\sec^2\theta\\\\\Rightarrow \sec^2\theta-1=\tan^2\theta~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Now, we have

[tex](\sec x-1)(\sec x+1)\\\\=\sec^2x-1\\\\=\tan^2x~~~~~~~~~~[\textup{from equation (i)}]\\\\=(\tan x)^2.[/tex]

Thus, the complete identity is

[tex](\tan x)^2=(\sec x-1)(\sec x+1).[/tex]

Thus, the required answer is tan x.

The number of painters, p, employed to paint a building is inversely proportional to the time taken to paint the building, b. Which equation best models the number of painters required to finish the painting?

Answers

Answer:

Option B. [tex]p=k/b[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

Let

p-----> the number of painters

b----> the time taken to paint the building

we know that

[tex]p*b=k[/tex]

so

[tex]p=k/b[/tex]

Answer:

B. [tex]p=\frac{k}{b}[/tex]

Step-by-step explanation:

Given,

The number of painters, p, employed to paint a building is inversely proportional to the time taken to paint the building, b

[tex]\implies p\propto \frac{1}{b}[/tex]

[tex]\implies p=\frac{k}{b}[/tex]

Where, k is the constant of proportionality,

Hence, the required equation that models the relation between p and b is,

[tex]p=\frac{k}{b}[/tex]

Option 'B' is correct.

The trainers you bought came in a cuboid shaped box. Which of the following is a net of a cuboid?

Answers

Here's what a net of a cuboid looks like if that was what you were asking.

Final answer:

The question involves identifying a net for a cuboid, which is a two-dimensional arrangement of rectangles that can be folded into a three-dimensional box shape.

Explanation:

The subject of the question is identifying a net of a cuboid. A net is a two-dimensional shape that can be folded to form a three-dimensional object. In the case of a cuboid, its net consists of 6 rectangles that correspond to the faces of the cuboid: top, bottom, front, back, and two sides. To create a net, you would draw these 6 rectangles in such an arrangement that when the edges are folded up, they would form the sides of a cuboid. The question requires understanding of basic geometry and how two-dimensional shapes can construct three-dimensional forms.

Which expressions are equivalent to 8(-10x+3.5y-7) check all that apply

Answers

Answer:

-80x + 28y - 424(-20x + 7y - 14)

Step-by-step explanation:

Use the distributive property a(b + c) = ab + ac:

8( -10x + 3.5y - 7)

= (8)(-10x) + (8)(3.5y) + (8)(-7)

= -80x + 28y - 42

8(-10x + 3.5y - 7)

= (4)(2)(-10x + 3.5y - 7)

= 4[(2)(-10x) + (2)(3.5y) + (2)(-7)]

= 4(-20x + 7y - 14)

The expression 8(-10x+3.5y-7) equivalent to -80x + 28y - 56.

How to solve an expression?

Let the expression be

8(-10x + 3.5y - 7)

Simplifying the above equation as

[tex]$\ 8\left(-10 x+\frac{35}{10} y-7\right)$[/tex]

Multiplying the equation, then we get

[tex]$-80 x+8 \times \frac{35}{10} y-8 \times 7$[/tex]

[tex]$-80 x+4 \times \frac{35}{5} y-56$[/tex]

[tex]$-80 x+4 \times 7 y-56$[/tex]

- 80x + 28y - 56

Therefore, the correct answer is option (b) - 80x + 28y - 56.

1-sin^2x/sinx-cscx

How do I solve this problem? I keep getting the wrong answer.

Answers

Answer:

-sinx

Step-by-step explanation:

a trig identity that is crucial to solving this problem is: sin^2 + cos^2 = 1

with knowing that, you can manipulate that and turn it into 1 - sin^2x = cos^x

so 1-sin^2x/sinx - cscx becomes cos^2x/sinx - cscx

it is also important to know that cscx is the same thing as 1/sinx

knowing this information, cscx can be replaced with 1/sinx

(cos^2x)/(sinx - 1/sinx)

now sinx and 1/sinx do not have the same denominator, so we need to multiply top and bottom of sinx by sinx; it becomes....

cos^2x

---------------------

(sin^2x - 1)/sinx

notice how in the denominator it has sin^2x-1 which is equal to -cos^2x

so now it becomes:

cos^2x

--------------

-cos^2x/sinx

because we have a fraction over a fraction, we need to flip it

cos^2x          sinx

1                  -  cos^2x

because the cos^2x can cancel out, it becomes 1
