what is the formula of circle
Find the next 3 terms and how’s the numbers changing
What is an equation of the line that passes through the point (–2, 5) and is perpendicular to the line y=12x + 5 ?
What is an equation of the line that passes through the point (–2, 5) and is perpendicular to the line y=12x + 5 ?
y = 12x + 5
- 12x + y = 5
gradient 1 = -a/b
= -(-12) / 1
= 12/1
= 12
gradient 2 × 12 = -1
Gradient 2 = -1/12
y - y1 = m (x - x1)
y - 5 = -1/12 ( x - (-2))
multiply all, by 12
12y - 60 = - 1 (x + 2 )
12y - 60 = -x - 2
x + 12y = - 2 + 60
x + 12y = 58

Answer:
x < -2
Step-by-step explanation:
its less than x, open circle
Answer:
x < -2
Step-by-step explanation:
Okay, so the dot is at -2 and is facing left. Left means less than, so, we know x is less than -2.
But we don't know if it's equal to or less than or just less than.
The dot is hollow, which in graphing means that it is not equal to or less than.
Therefore, the answer is x < -2

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 that are different in colour?
Answer:
15/28Step-by-step explanation:
There are 3 blue, 5 red and the total of 8 marbles.
Two different colored marbles are:
blue, then red or red, then blueFind the probability of each case:
P(b, r) = 3/8*5/7 = 15/56P(r, b) = 5/8*3/7 = 15/56Required probability is:
P(different color) = 15/56*2 = 15/28Answer:
15/28 is the probability of getting 2 that are different in colour.
Step-by-step explanation:
3 blue and 5 red marblesHe is going to pick any marble, in second try, it must be a different colour marble.
total marble: 3 + 5 = 8 marbles
For blue marble:
In first try for blue marble: 3/8
total marble will decrease by 1, 7 marbles.second try for red marble: 5/7
probability then: 5/7 * 3/8 = 15/56 is the probability for blue marble.
For red marble:
In first try for red marble: 5/8
total marble will decrease by 1, 7 marbles.second try for blue marble: 3/7
probability then: 5/8 * 3/7 = 15/56
**
total probability of getting different in colour:
15/56 + 15/56
15/28 **
What fraction is equal to 75% of 1/3
Answer:
1/4
Step-by-step explanation:
1.) Take 75% and convert it to a decimal, which is 0.75
2.) Then multiply 1/3 by 0.75
3.) Your answer is 0.25, and when 0.25 is converted to a fraction it is 1/4.
75% of 1/3 can be expressed as the fraction 1/4 by convert the percentage to a decimal, multiply it by the original fraction, and simplify the resulting fraction
To find the fraction that is equal to a given percentage of another fraction, follow these steps:
Step 1: Convert the percentage to a decimal by dividing it by 100. In this case, 75% is equivalent to 0.75.
Step 2: Multiply the decimal by the original fraction. In this case, 0.75 * 1/3 = 0.25/1.
Step 3: Simplify the resulting fraction, if possible. In this case, the fraction 0.25/1 can be simplified to 1/4.
Therefore, 75% of 1/3 is equal to the fraction 1/4.
To find the fraction that represents a given percentage of another fraction, convert the percentage to a decimal, multiply it by the original fraction, and simplify the resulting fraction if necessary. In this case, 75% of 1/3 is equal to the fraction 1/4.

If 1 inch represents 68 miles on a map, then how many inches will represent 8600 miles
Answer:
126.470588235
Step-by-step explanation:
I like to set these up like how I set up my radian conversions so what I do is I have one unit on top of a fraction and another on the bottom so it would look like this 1/68 = x/8600 this equation will let us solve for x which would be our inches to get 8600 so we just times 1/68 by 8600 and get 126.470588235 and just to check 126.470588235 * 68 = 8600

The length of a
rectangle is represented by
4a + 3b, and its width is
represented by 7a – 2b. Write
a polynomial for the perimeter
of the rectangle.
Solution:
Given:
Length of rectangle = 4a + 3bWidth of rectangle = 7a - 2bPerimeter of rectangle = 2W + 2LLet's simplify the perimeter of the rectangle by using the expression for the perimeter.
=> 2W + 2L=> 2(7a - 2b) + 2(4a + 3b)=> 14a - 4b + 8a + 6b=> 22a + 2bHence, the polynomial that represents the perimeter of the rectangle is 22a + 2b.

7) Solve the equation for the variable given.
Solve for x.
m=2x+b/3
Answer:
x= m/2 - b/6
(its a lot of work...)
Step-by-step explanation:
1. Subtract 2x from both sides
-2x=2x+b/3-2x
2. Simplify
-2x=b/3
3. Factor
x(m-2)=b/3
4. divide both sides by m-2; m≠2
x(m-2)/m-2=b/3/m-2 m≠2
5. Simplify again...
x=b/3(m-2); m≠2

Compound interest are used to determine interest on deposits
The balance as a function of time is [tex]y = 2000 * (0.2625)^{4t}[/tex]
How to determine the functionThe given parameters are:
Principal, P = $2000
Rate, r = 5%
n = 4, (quarterly)
The amount remaining is calculated as:
[tex]A = P * (1+ r/n)^{nt}[/tex]
So, we have:
[tex]A = 2000 * (1+ 5\%/4)^{4t}[/tex]
Simplify
[tex]A = 2000 * (0.2625)^{4t}[/tex]
Rewrite as:
