General Circle function: [tex](x-h)^2+(y-k)^2=r^2[/tex], where h is the x-coordinate of the center, k is the y-coordinate of the center, and r is the radius.
The radius of the circle is half the diameter so: 8 / 2 = 4
The x-coordinate of the circle is 5
The y-coordinate of the circle is -2
Plug in.
[tex](x-5)^2+(y-(-2))^2=4^2[/tex]

write the equation -1/2x - 2y = -4 in slope intercept form
Answer:
y= -1/4x+2
Step-by-step explanation:
y=mx+b is the slope intercept form.
We first must isolate y by adding 1/2x on both sides.
-2y=-4+1/2x
next we multiple by -1/2 to get rid of the -2
y=2-1/4x
y=-1/4x+2

Step-by-step explanation:
The square length of hypotenus (the side lenght that sees 90 degrees) is equal to sum of square length of side lengths
Let x represent the missing side

After solving the system x+2y=10 and x-2y=2. What is the sum of x+y equal to?
Answer:
The sum of x and y is 8.
Step-by-step explanation:
x+2y=10
x-2y=2
------------
2x = 12, so x = 6. Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2. The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
Answer:
6 + 2 = 8
Step-by-step explanation:
[tex]x + 2y = 10 \\ + \\ x - 2y = 2 \\ = \\ 2x = 12 \\ x = 6 \\ 6 + 2y = 10 \\ 2y = 4 \\ y = 2 \\ x + y = 6 + 2 = 8[/tex]

Use the Pythagorean Theorem to find the missing length and then round the
result to the nearest tenth.
b = 2, c = 3
a =
Answer:
A=2.2
Step-by-step explanation:
PYTHAGOREAN THEOREM:
a^2+b^2=c^2
STEP 1:
Lets put in the given number into the Theorem.
x^2+ 2^2= 3^2
I put x in the "a" place because there is no Number that goes into there, so we put in a variable.
STEP 2:
We find the numbers, which are
x^2+4=9
STEP 3:
We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)
After subtracting from both sides we have
x^2=5
STEP 4:
Once we have that, we have to find the square root of 5 which is 2.23606798
STEP 5:
Since you say to round to the nearest tenth, we get 2.2
TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex] Which is the same as 2.23606798.

James goes out to eat with Janet, and their meal costs $68. There is a sales tax of 7% and Janet wants to leave a 20% tip. How much money will Janet spend on the entire meal?
Answer:
$86.36
Step-by-step explanation:
Tax: 7%, or 0.07
Tip: 20%, or 0.2
Substitute the values:
Tip: 68 * 0.07 = 4.76
Tip: 68 * 0.2 = 13.6
Just the meal cost: 1 * 68 = 68
Add these all together
4.76 + 13.6 + 68 = 86.36
Thus, the total cost of the meal would be $86.36
1) Em uma rua há duas casas e em cada casa há dois galinheiros. Em cada galinheiro há dois cercados, em cada, há duas galinhas, e cada galinha tem dois pintinhos. Qual o total de pintinhos dessas casas?Pergunta sem título *
Answer:
Hay 32 pollitos en total.
Step-by-step explanation:
Para contestar a la pregunta planteada se debe realizar el siguiente razonamiento matemático:
Casas = 2
Gallineros = 2
Cercados = 2
Gallinas = 2
Pollitos = 2
2 x 2 x 2 x 2 x 2 = X
4 x 2 x 2 x 2 = X
8 x 2 x 2 = X
16 x 2 = X
32 = X
Por lo tanto, hay 32 pollitos en total.

Find the difference. Express the answer in scientific notation.
Va
(8.64 x 1020)- (7 83x 1020)
O 8.1x 10
O 0.81 x 1020
O 8.1 x 1021
O 0.81x1040
Both values have the same exponent ( they are both 10^20) so first subtract the numbers:
8.64 - 7.83 = 0.81
You would now have 0.81 x 10 ^20
But to be in scientific notation you need a number to the left of the decimal.
0.81 would become 8.1 and because you move the decimal 1 place to the left, you would subtract 1 from the original exponent so 10 ^20 would become 10 ^19
The answer is 8.1 x 10 ^ 19
Answer:
B = 0.81 x 10^ 20
Step-by-step explanation:
=(8.64 x 10^ 20)- (7 83x 10^20)
=8.1 x 10^19
which is also written as
= 0.81x 10^20

Is 3/4greater or less than 1/2....is it 1/2?
Answer: yes 3/4 is greater
converting both fractions to decimals. The decimal 0.75 is bigger than 0.5, so 3/4 is bigger than 1/2.
Answer:
3/4 is greater than 1/2.
Step-by-step explanation:
One way to compare fractions is by making them have the same denominator.
You can do this by finding the least common denominator (LCM).
First, list the multiples of each denominator.
4: 4, 8, 12, 16, 20
2: 2, 4, 6, 8, 10
As you can see, 4 is the LCM.
Now, change the fractions to where they denominators of 4.
**WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MUST ALSO MULTIPLY IT BY THE NUMERATOR.**
[tex]3/4*1/1=3/4[/tex] (STAYS THE SAME)
[tex]1/2*2/2=2/4[/tex]
Now, as you can see, 3/4 is larger than 2/4.
Therefore, 3/4 is larger than 1/2.
The difference between two positive numbers is 7 and the difference between thes
cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,
find the value of 'A-B'.
The difference between two positive numbers is 7 and the difference between these cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,
To Find :-A - BSolution :-So,
Let the number be n and m
A = n × m = nm
B = n² + m² = (n + m)²
Now
n³ - m³ = 805
(n - m) (n² + m² + nm) = 805
Since difference is 7
7 × n² + m² + nm = 805
n² + m² + nm = 805/7
n² + m² + nm = 115
(n² + n) + (m² + m) = 115
A + B = 115
Now
On squaring the first eq.
(n - m)² = (7)²
(n - m)² = 49
B - 2A = 49
Now
A + B - B + 2A = 115 - 49
A + 2A = 66
3A = 66
A = 66/3
A = 22
By using 2
B - 2(22) = 49
B - 44 = 49
B = 49 + 44
B = 93
A - B = 22 - 93 = -71
[tex]\bold{ A-B=-71 }[/tex]

classify the triangle with the given side lengths as acute, right, obtuse, or not a triangle:
9,15,19 NOT A RIGHT TRIANGLE THANKS FOR THE HELP! NO SPAMS OR LINKS PLEASE
Answer:
It is not a right triangles because 15^2 + 13^2 is NOT EQUAL to 19^2
let x, y, and z be the angles inside the triangle.
Law of cosines says:
19^2 = 13^2 + 15^2 - 2(13)(15)cos x
361 = 169 + 225 - 390 cos x
-33 = -390 cos x
-33/-390 = cos x
11/130 = cos x
x = inverse cosine (11/130)
= 85.14609471338569.....
Per law of sines:
sin x/19 = sin y / 13
(13/19)sinx = sin y
inverse_sine ( (13/19) sin x) = y
y = 42.9810733896016548....
Per law of sines
sin x/19 = sin z / 15
z = inverse_sine( (15/19) sin x)
= 51.8728352950227805....
So it is an acute triangle and yes, these angles add up to 180
Answer:
acute
