Answer 1

Answer:

Option b is the correct answer

Step-by-step explanation:

[tex]\cos x = -\frac{12}{13}[/tex] (Given)

Formula relating sin x and cos x is given as below:

[tex]\sin^2x = 1-\cos^2x[/tex]

[tex]\implies \sin^2x = 1-\bigg(-\frac{12}{13}\bigg)^2[/tex]

[tex]\implies \sin^2x = 1-\frac{144}{169}[/tex]

[tex]\implies \sin^2x = \frac{169-144}{169}[/tex]

[tex]\implies \sin^2x = \frac{25}{169}[/tex]

[tex]\implies \sin x =\pm\sqrt{ \frac{25}{169}}[/tex]

[tex]\implies \sin x =\pm \frac{5}{13}[/tex]

It is given that: 180° < x < 270°. This means x falls in the third quadrant. In third quadrant sin ratio is negative.

[tex]\implies \sin x =- \frac{5}{13}[/tex]

Now, we will find the value of tanx by dividing sinx by cosx.

[tex]\implies \tan x =\frac{\sin x}{\cos x}[/tex]

[tex]\implies \tan x = \frac{-5/13}{-12/13}[/tex]

[tex]\implies\red{\bold{ \tan x =\frac{5}{12}}}[/tex]

tan (90° + x) and tan x both lie in the interval 180° < x < 270°. So, the values of both will be equal.

[tex]\implies \tan (90\degree + x ) =\tan x[/tex]

[tex]\implies \huge{\purple{\tan (90\degree + x ) =\frac{5}{12}}}[/tex]

Answer d because the y intercept is 3 and its a positive slope

this net can be folded to make a square pyramid. what is the surface area of the pyramid

Answers

Answer:  

[tex]85in^2[/tex]

Step-by-step explanation:

to find the surface area we need to find the followng areas:  

area of the square  area of a triangle and multiply it by 4 (because there are 4 triangles)

And once we have those areas, we add them to find the surface area.

Area of the square:

the formula to find the area of a square is:

[tex]a_{square}=l^2[/tex]

where [tex]l[/tex] is the length of the side: [tex]l=5in[/tex]

thus the area of the square is:

[tex]a_{square}=(5in)^2[/tex]

[tex]a_{square}=25in^2[/tex]

Area of the triangles:

the are of 1 triangle is given by

[tex]a_{triangle} =\frac{b*h}{2}[/tex]

where [tex]b[/tex] is the base of the triangle: [tex]b=5in[/tex] (the base of the triangle is the side of the square)

and [tex]h[/tex] is the height of the triangle: [tex]h=6in[/tex]

thus, the area of 1 triangle is:

[tex]a_{triangle} =\frac{(5in)*(6in)}{2}[/tex]

[tex]a_{triangle} =\frac{30in^2}{2}[/tex]

[tex]a_{triangle} =15in^2[/tex]

the area of the 4 triangles is (we multiply by 4):

[tex]a_{4-triangles}=4(15in^2)[/tex]

[tex]a_{4-triangles}=60in^2[/tex]

finally we add the area of the square and the area of the 4 triangles to find the total surface area:

[tex]Surface=25in^2+60in^2[/tex]

[tex]Surface=85in^2[/tex]

Circle X with a radius of 6 units and circle Y with a radius of 2 units are shown. Circles X and Y are shown. Circle X has a radius of 6 units and circle Y has a radius of 2 units. Which steps would prove the circles similar?
-Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 4.
- Translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle Y by a scale factor of 4.
-Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.
-Translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle Y by a scale factor of 3.

Answers

Answer & step-by-step explanation:

to arrive at the similarity, the transformation must be as follow:

the small circle will be dilated for a specific scale factor,

the radius of X circle is R= 6, and the radius of the small circle is r = 2

besides, two circles are similar if and only if R = r, (their radius ar equal)

therefore  r = 2*k = 6, and from where k = 6 / 2 = 3 units

the answer is

Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.

Answer:

Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.

Step-by-step explanation:

To prove circles are similar:

Translate the circles so that they share a common center point. (The circles are now concentric as they have the same center).

Dilate the smaller circle to increase its size to coincide with the larger circle.  The amount that the circle needs to be dilated by is the scale factor.

As the radius of circle Y is 2 and the radius of circle X is 6, determine the scale factor by dividing the larger radius by the smaller radius:

scale factor = 6 ÷ 2 = 3

Solution:

Translate the circles so they share a common center point, and dilate circle Y by a scale factor of 3.

Answers

Answer:

Answer:

[tex]144ft^{2}[/tex] (144ft^2)

Step-by-step explanation:

Since the living room is 6 inches by 6 inches, the formula of the living room can be seen as: [tex]6in^{2}[/tex]. And since each inch is equal to 2 feet, (6*2=12) we can turn the equation into: [tex]12ft^{2}[/tex]. 12 times 12 is 144, so the answer is [tex]144ft^{2}[/tex]

According to a survey, 15% of city workers take the bus to work. donatella randomly surveys 10 workers. what is the probability that exactly 6 workers take the bus to work? round the answer to the nearest thousandth.

Answers

The probability that exactly 6 workers take the bus to work is 0.001

How to determine the probability?

The given parameters are:

Sample size, n = 10Required sample = exactly 6Probability of success, p = 15%

The probability that exactly 6 workers take the bus to work is calculated using the following binomial expression

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x{[/tex]

Part 2: Approximately what value of will give her a box with the greatest volume? Explain your reasoning.
( only need part 2 already have part one thx)

Answers

The value of  x that gives the box the greatest volume is approximately 2.08

How to determine the value that gives the greatest volume?

The equation of the volume of the box is given as:

V(x) = x(12 - 2x)(13 - 2x)

Expand

V(x) = (12x - 2x^2)(13 - 2x)

V(x) = 156x - 24x^2 - 26x^2 + 4x^3

V(x) = 156x - 50x^2 + 4x^3

Differentiate the function

V'(x) = 156 - 100x + 12x^2

Set to 0

156 - 100x + 12x^2 = 0

Rewrite as:

12x^2 - 100x + 156 =0

Divide through by 4

3x^2 - 25x + 39 =0

Using a graphing calculator, the values of x are:

x = 2.08 and x = 6.26

Substitute these values of x in V(x)

V(2.08) = 2.08 * (12 - 2 * 2.08)(13 - 2 * 2.08) = 144.16

V(6.26) = 6.26 * (12 - 2 * 6.26)(13 - 2 * 6.26) = -1.56

The volume cannot be negative.

So, we have:

V(2.08) =  144.16

Hence, the value of  x that gives the box the greatest volume is approximately 2.08
