What is the equation of a circle centered at the origin with radius 20​

Answers

Answer 1

Answer:

we have a rule

(x-h)²+(y-v)²=r²

while h is the x intercept

v is y intercept

r is the radius

so the answer will be

x²+y²=400

or

x²+y²=20²

To find:

The simplified form of the given expression.

Solution:

We have,

[tex]\dfrac{2}{a-2}-\dfrac{8}{a^2-4}[/tex]

It can be written as

[tex]=\dfrac{2}{a-2}-\dfrac{8}{a^2-2^2}[/tex]

[tex]=\dfrac{2}{a-2}-\dfrac{8}{(a-2)(a+2)}[/tex]            [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

Taking LCM, we get

[tex]=\dfrac{2(a+2)-8}{(a-2)(a+2)}[/tex]

[tex]=\dfrac{2a+4-8}{(a-2)(a+2)}[/tex]

[tex]=\dfrac{2a-4}{(a-2)(a+2)}[/tex]

[tex]=\dfrac{2(a-2)}{(a-2)(a+2)}[/tex]

Cancel out the common factors.

[tex]=\dfrac{2}{a+2}[/tex]

Therefore, the simplified form of the given expression is [tex]\dfrac{2}{a+2}[/tex].

Given the following 30-60-90 triangle , find the value of x and y Round to the nearest tenth x = 5.2 X = 6 Y = 6 Y = 5.2​

Answers

Step-by-step explanation:

tan30° = Opposite/Adjacent = 3/x.

=> 3/x = √3/3, x = 3√3 = 5.2.

sin30° = Opposite/Hypotenuse = 3/y.

=> 3/y = 1/2, y = 6.

At the carnival, it costs $10 to enter. It then costs $1.50 per ride you go on.
If you have $28, how many rides can you go on? *
1 point

Answers

Answer:

18.6

Step-by-step explanation:

28 divided by 1.50 equals 18.6

The number of rides will be equal to 12 in the Carnival.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that at the carnival, it costs $10 to enter. It then costs $1.50 per ride you go on. The total amount is $28.

The number of rides will be calculated by forming an equation below,

A = 10 + 1.5R

28 - 10 =1.5R

1.5R = 18

R = 18 / 1.5

R  = 12

Therefore, the number of rides will be equal to 12 in the Carnival.

Dan has twice as many stickers as Cam does. If Dan gives Cam 15 of his stickers he will still have 22 more than Cam. How many stickers does each boy have?

Answers

You can solve this question by setting up an equation. Dan has twice as many stickers as Cam does. We can call Dan 2x, and Cam x. So the equation would be:
2x-15=x+22.
Then solve this equation:
Add 15 on both sides
2x=x+37
Subtract x on both sides
2x-x=37
X=37.
Therefore Cam has 37 stickers, and Dan has 74 stickers.

Four basketballs and six baseballs cost $44. Five basketballs and four baseballs costs $48. Determine the cost for one basketball and one baseball.

Answers

Answer:cost for basket ball= $8 and

cost of baseball = $2

Step-by-step explanation:

Step 1

Let the cost of basket ball be represented as x

and cost of  baseball = y          such that

Four basketballs and six baseballs cost $44 will be expressed as

4x+ 6y= 44  --- eqn 1   also

Five basketballs and four baseballs costs $48 will be expressed as

5x+ 4y= 48--- eqn 2

Step 2

Having obtained two expressions we can now sole

4x+ 6y= 44  --- eqn 1

5x+ 4y= 48--- eqn 2

multiplying eqn 1 by 5 and eqn 2 by 4

20x+ 30y =220---- eqn 3

20x+ 16y=192-----eqn 4

subtracting equation 4 from 3   we now have

14y=28

y= 28/14

y=2 = $2

from equation 1

4x+ 6y= 44, putting the value of y=7 to find x

4x+ 6(2)= 44

4x+12= 44

4x= 44-12

4x=32

x= 32/4

x=8=$8

cost for basket ball= $8 and

cost of baseball = $2

write the equation of the cirlcle with diameter endpoints of (-6,3) and (-14,13)

Answers

Answer:

(x+10)² + (y-8)² = 41

Step-by-step explanation:

First, we find the length of the diameter.

from distance formula, d = SQR ROOT OF [(-14+6)² + (13-3)²]

diameter = SQR ROOT OF [8² + 10²] = √164 = √4√41 = 2√41

*****    so the radius is half that, r =√41

The center of the circle is at the midpoint of the diamater.

x = (1/2)(-6 + -14) = (1/2)(-20) = -10

y = (1/2)(3 + 13) = (1/2)(16) = 8

center (h,k) = (-10,8)

circle equation: (x-h)² + (y-k)² = r²

(x- -10)² + (y - 8)² = (√41)²

(x+10)² + (y-8)² = 41

What is the value of 6x+7y−5 when x = 2 and y = 3?

Answers

Answer:

28

Step-by-step explanation:

6(2) + 7(3) - 5

12 + 21 -5

It's a good idea to get into the habit of using parenthses

when substituting numbers in for variables.

Since x = 2 and y = 3, 6x + 7y - 5 is 6(2) + 7(3) - 5.

Simplifying from here, we get 12 + 21 - 5 or 33 - 5 which is 28.

Find the missing side

Answers

Answer:

72

Step-by-step explanation:

The pythagorean theorem states that in a right triangle A^2 + B^2 = C^2 where A and B are the two smaller sides and C is the hypotenuse.

Because of this, in this triangle 30^2 + B^2 = 78^2

Which means B^2 = 5184

And B = 72

An airplane climbs at an angle of 16° with the ground. Find the ground
distance the plane travels as it moves 2500 m through the air.

Please help me with this!

Answers

Answer:

2403.2

Step-by-step explanation:

We get the length of the hypotenuse, and the base angle. To find the length of the base, we use the cosine of 16° since it is equal to the adjacent side length/ hypotenuse side length or cos 16°= x/2500. The isolate x by multiplying both sides by 2500. The cos 16° is around 0.96126, multiplied by 2500 (cos 16°(2500)) = 2403.1

Bar graph Please select the best answer from the choices provided Passage: What Causes Earthquakes Natural earthquakes occur mostly from tectonic movements of the plates. Tectonic plates are large parts of the oceanic and continental lithosphere. The lithosphere is the solid outer section of Earth's crust. These sometimes shift into various positions both under water and above. Such movements generally occur along fault lines. When two rocks slide against each other, they create fault lines. These fault lines can be both extremely narrow or miles wide. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. Movement between the tectonic plates is rarely smooth. When the plates slide against each other, they create a tremendous amount of friction. This friction forms seismic energy that travels in waves through the surface of the Earth. This causes the earthquake. While normal energy travels above the surface of the Earth, seismic energy travels under the Earth's surface. This creates more tension between the land plates, causes more shifting, and creates more fault lines. The spot below the Earth's surface where the rocks break against each other is called the focus of the earthquake. The place exactly above the focus on the surface of the planet is called the epicenter of the earthquake. Sometimes, earthquakes can also be man-made instead of natural. These can sometimes be caused due to explosions underground. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing. But the seismic energy formed due to these explosions is rarely very strong. Therefore, the strength of the earthquakes caused is not very high.Question: In What Causes Earthquakes," which detail supports the idea that friction exists between the plates underground? A. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. B. Movement between the tectonic plates are rarely smooth. C. When two rocks slide against each other, they create fault lines. D. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing.
