identify the center and radius of the circle (x-7)^2+(y-11)^2=36

Answers

Answer 1

Answer:

Centre is [tex](7,11)[/tex]

Radius is [tex]6[/tex]

Step-by-step explanation:

The general equation for a circle is written in the form [tex](x-a)^2+(y-b)^2=r^2[/tex] , where [tex](a,b)[/tex] is the centre of the circle, and [tex]r[/tex] is the radius.

For your circle, [tex](x-7)^2+(y-11)=36[/tex], we can compare it with the general equation to find the centre and radius.

[tex]-a = -7[/tex]

[tex]-b = -11[/tex]

[tex]r^2 = 36[/tex]

Therefore, [tex]a=7[/tex], [tex]b=11[/tex] and [tex]r=6[/tex].

Centre at [tex](a,b)[/tex] which is [tex](7,11)[/tex] .

Answer:

40cm^2

perimeter:24cm

Step-by-step explanation:

Area: First of all, you can see that the missing height of the shape is 3cm. By adding 4 and 3, you get 7. Then, by multiplying 7 and the length of the shape (6cm), you get 42cm^2. After that, you have to multiply 2cm and 3cm to get the blank area in the bottom right corner to get 6cm^2. Finally, you can subtract 42cm^2(the whole area) by 6cm^2 (the blank area) to get 40cm^2.

Perimeter: Okay! To get the first missing measurement (the one on the left), you have to imagine 4cm being moved to that side. 3cm is parallel to the missing blank space under the 4cm. This means you have to get 7cm (you add 4 and 3). To get the other missing measurement (bottom of the shape) you must see that 6cm would be parallel to the bottom. Since 2cm is also parallel to the bottom, you would have to subtract 2 from 6 to get the bottom of the shape's length, which is 4. Finally, you would have to add 6, 4, 3, 2, 4 and 7 together to get 24cm.

Some one plz help meh I need to understand and I dont

Answers

Answer:

It's asking you to find the inputs of the function.

Step-by-step explanation:

Basically, when you input something, you replace "x" in the equation with the number you want to input. For example, if I had the equation: 5x/6+5, then I wanted to input "5", then 5 would replace x in the equation, making 5(5)/6+5. The output they are giving you is simply evaluating the equation that you used to input x, so basically in the case I gave you, the output would be 5(5)/6+5, or 25/6+5, and 55/6. Using the outputs, they want you to find the inputs.

the data shows the length and weight of a species of fish based on the data


which is closest to the length of a fish that weighs 4.2 pounds

Answers

Answer:

36.5 inches

Step-by-step explanation:

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Pick any two corresponding points from the table

So, we have:

[tex](x_1,y_1) = (8,1.21)[/tex]

[tex](x_2,y_2) = (12,1.63)[/tex]

So:

[tex]m =\frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{1.63 - 1.21}{12 - 8}[/tex]

[tex]m =\frac{0.42}{4}[/tex]

[tex]m =0.105[/tex]

The linear equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 0.105 * (x - 8) + 1.21[/tex]

Open bracket

[tex]y = 0.105x - 0.84 + 1.21[/tex]

[tex]y = 0.105x + 0.37[/tex]

To get the length closest to 4.2lb,

we set [tex]y = 4.2[/tex]

Then solve for x

So, we have:

[tex]y = 0.105x + 0.37[/tex]

[tex]4.2 = 0.105x + 0.37[/tex]

Collect like terms

[tex]0.105x= 4.2 - 0.37[/tex]

[tex]0.105x= 3.83[/tex]

Solve for x

[tex]x= 3.83/0.105[/tex]

[tex]x\approx 36.5[/tex]

what did you observe with the product of wavelength and frequency for each color? what is the significance of this value?


what can you say about the speed of the different colors?​

Answers

Answer:

The responses to the given question can be defined as follows:

Step-by-step explanation:

Its color palette depends on how much radiation reaches the eyes or the intensity of it. If indeed the duration of a wave is less than 400 nm, it is called UV and much more than 750 nm simple pleasures light it is (IV). The shorter wavelength implies a much more frequent spectrum and lower frequencies are the longer wavelengths.  

The shorter the distance, the higher it's indeed. Since the red duration has been longer, the intensity is low. The purple has a smaller range and a high frequency, on the other side. The wavelengths are shorter as well as the frequencies are lower than the red, and it will differ even as violet goes, Remember that even more power is provided with the longer the duration of color. That wave/frequency color rises and is longer the purple color is becoming the lowest color.

Since A&B have 38. There must be 61-38=23 in C.

Since there is a difference of 16 between A and C, there must be 7 in A (23-16=7). It couldn’t be 23+16=39 in A, because there are only 38 in A and B combined.

So it’s:

A deli orders ham and turkey. The ratio of the number of ham slices to the number of turkey slices is 2:3. What is the ratio of the number of turkey slices to the total of ahem and turkey slices

Answers

Answer:

3 :5

Step-by-step explanation:

A deli orders ham and turkey.

The ratio of the number of ham slices to the number of turkey slices is 2:3.

Hence:

Ham slices: Turkey slices

2:3

Sum of proportion = 2 + 3 = 5

Ratio of turkey slices = 3

Ratio of the total of ham and turkey slices = sum of proportion = 5

Therefore, the ratio of the number of turkey slices to the total of ham and turkey slices is

The sides of a polygon are 3cm,5cm,6cm,8cm and 10cm.The perimeter of a similar polygons is 48cm.Find the sides of the second polygon.

Answer:

[tex]a'=4.5[/tex]

[tex]b'=7.5[/tex]

[tex]c'=9[/tex]

[tex]d'=12[/tex]

[tex]e'=15[/tex]

Step-by-step explanation:

From the question we are told that:

Sides of Polygon 1

 a=3

 b=5

 c=6

 d=8

 e=10

Perimeter of polygon 2 P_2=48

Generally the equation for Polygon 1 is mathematically given by

 P_1=a+b+c+d+e

 P_1=3+5+6+8+10

 P_1=32

Generally the sides of similar polygon with Perimeter P_2=48 is mathematically given by

Side\ of\ polygon\ 2 =\frac{side\ of\ polygon\ 1}{perimeter\ of\ polygon\ 1}*perimeter\ of\ polygon\ 2

Therefore

[tex]a'=\frac{a}{P_1}*P_2\\a'=\frac{3}{32}*48[/tex]

[tex]a'=4.5[/tex]

[tex]b'=\frac{b}{P_1}*P_2\\b'=\frac{5}{32}*48[/tex]

[tex]b'=7.5[/tex]

[tex]c'=\frac{c}{P_1}*P_2\\c'=\frac{6}{32}*48[/tex]

[tex]c'=9[/tex]

[tex]d'=\frac{d}{P_1}*P_2\\d'=\frac{8}{32}*48[/tex]

[tex]d'=12[/tex]

[tex]e'=\frac{e}{P_1}*P_2\\e'=\frac{10}{32}*48[/tex]

[tex]e'=15[/tex]

ABCD is a quadrilateral with A(8,21),B(10,27),C(26,26) and D(18,2). Determine whether ABCD is a trapizoid

Answers

Answer:

ABCD is a trapezoid

Step-by-step explanation:

Given points of the quadrilateral:

A(8,21),B(10,27),C(26,26) and D(18,2)

To show whether ABCD is a trapezoid, we find a pair of parallel sides in ABCD. If two of its sides are parallel to each other then ABCD is a trapezoid.

Step 1: With the given points, sketch a graph. The diagram is attached to this response.

Step 2: As shown in the diagram, the two sides that are likely to be parallel are AB and CD

If these two sides have same gradient/slope, then the quadrilateral is a trapezoid.

Now calculate the slopes of those sides using the slope formula;

m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Calculate the slope of AB (where x₁ = 8, y₁ = 21, x₂ = 10, y₂ = 27)

m(AB) = [tex]\frac{27-21}{10-8}[/tex]

m(AB) = [tex]\frac{6}{2}[/tex]

m(AB) = 3

Calculate the slope of CD (where x₁ = 26, y₁ = 26, x₂ = 18, y₂ = 2)

m(CD) = [tex]\frac{2-26}{18-26}[/tex]

m(CD) = [tex]\frac{-24}{-8}[/tex]

m(CD) = 3

Since the two slopes - m(AB) and m(CD) slopes are equal to 3, the quadrilateral ABCD is a trapezoid.

If cos(x) = 3/5 and sin x < 0, find sin(2x) as a fraction in simplest terms.
sin(2x) =

Answers

Answer:

NOT 24/25 and NOT -4/5

Step-by-step explanation:

took the quiz

If cos(x) = 3/5 and sin x < 0, sin(2x) is equal to -24/25 as a fraction in simplest terms.

To find sin(2x), we can use the double-angle formula for sine:

sin(2x) = 2 * sin(x) * cos(x)

Given:

cos(x) = 3/5

sin(x) < 0

We need to determine sin(x) based on the given information.

Using the Pythagorean identity, sin^2(x) + cos^2(x) = 1:

[tex](sin(x))^2 + (cos(x))^2 = 1\\(sin(x))^2 + (3/5)^2 = 1\\(sin(x))^2 + 9/25 = 1\\(sin(x))^2 = 1 - 9/25\\(sin(x))^2 = 16/25[/tex]

sin(x) = -4/5

Now we can  the values into the double-angle formula for sine:

sin(2x) = 2 * sin(x) * cos(x)

sin(2x) = 2 * (-4/5) * (3/5)

sin(2x) = (-8/5) * (3/5)

sin(2x) = -24/25

Therefore, sin(2x) is equal to -24/25 as a fraction in simplest terms.
