Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
(A) x2 + (y – 3)² = 36, is the equation that represents circles with a diameter of 12 units and a center on the y-axis.
What are equations?In its most basic form, an equation is a mathematical statement that shows that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.So, the standard form for calculating the equation of a circle is as follows:
(x-a)² + (y-b)² = b = r²
Where;
(a, b) is the circle's center.The radius of the circle is denoted by r.Information:
diameter = 12 unitsradius = 12/2 = 6 unitsIf the center is on the y-axis, it will be at (0, 3).
By substituting into the formula, we get (x-0)² + (y-3)² = 6² is equivalent to
x²+ (y-3)² = 36Therefore, the equation that represents circles with a diameter of 12 units and a center on the y-axis is (A) (A) x2 + (y – 3)² = 36.

(F) 0,1,2,3,4

(I) 3,5,7,9,11
The first five terms of a sequence with explicit formula a(n) = 2n - 1 are 1,3,5,7,9 (G)
An arrangement of numbers with particular pattern is called a sequence. In general, there are four types of sequence: arithmetic sequence, geometric sequence, quadratic sequence, and special sequence.
Suppose we are given an explicit formula for the nth term of a sequence, then its terms can be evaluated by substituting n = 1, 2, ...
The explicit formula of the given sequence:
a(n) = 2n - 1
Take n = 1, then
a(1) = 2.(1) - 1 = 1
Take n = 2, then
a(2) = 2.(2) - 1 = 3
Take n = 3, then
a(3) = 2.(3) - 1 = 5
Take n = 4, then
a(4) = 2.(4) - 1 = 7
Take n = 5, then
a(1) = 2.(5) - 1 = 9
Hence, the first five terms are 1,3,5,7,9 (G)

Determine whether each set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
4.2,6.4,7.6
Yes, the given set of numbers can be the measures of the sides of a triangle. The triangle is obtuse.
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
4.2 + 6.4 > 7.6
6.4 + 7.6 > 4.2
7.6 + 4.2 > 2.6
Hence, these set of numbers can be the measures of the sides of a triangle.
According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:
acute if [tex]a^{2} + b^{2} < c^{2}[/tex]
obtuse if [tex]a^{2} + b^{2} > c^{2}[/tex]
right if [tex]a^{2} + b^{2} = c^{2}[/tex]
∴The longest side is 7.6.
Hence, a = 4.2, b = 6.4 and c = 7.6;
Consider [tex]a^{2} + b^{2}[/tex] :
= [tex]4.2^{2} + 6.4^{2}[/tex]
= 58.6.
Now consider [tex]c^{2}[/tex] :
= [tex]7.6^{2}[/tex]
=57.76.
Thus, [tex]a^{2} + b^{2} > c^{2}[/tex]
Hence, the triangle is obtuse.

A medical insurance policy requires Ana to pay the first $100 of her hospital expense. The insurance company will then pay 90% of the remaining expense. Ana is expecting a short surgical stay in the hospital, for which she estimates the total bill to be about $4,700. How much (in $) of the total bill will Ana owe
The total bill that Ana would pay is $560.
What is the total bill Ana would pay?The total bill that Ana owes is the sum of the first $100 and 10% of the remaining bill since the insurance company would pay 90% of the bill.
The mathematical operation that would be used to determine the total bills are addition, multiplication and subtraction. Addition is the process of determining the sum of two or more numbers. Subtraction is the process of calculating the difference between two or more numbers. Multiplication is the process of determining the product of two or more numbers.
Total bill = first $100 + 90%(total bill - $100)

Answer:
The value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.
Step-by-step explanation:
It is given that the expression given below is to be simplified using the order of operations;
The given expression is;
=> (3×2)² + 8 = ___² + 8
Now, let us assume that the blank space is 'x' in the above-mentioned question;
Firstly,
We will solve the terms within brackets as per BODMAS rules that is multiplication of both the terms;
=> (3×2)² + 8 = x² + 8
=> 6² + 8 = x² + 8
Now, we will solve the squares of the terms given above;
=> 36 + 8 = x² + 8
Now, we will add the terms as per BODMAS rules;
=> 44 = x² + 8
=> 44 - 8 = x²
Now, we will subtract the terms as per BODMAS rules;
=> 36 = x²
Now, we will square-root both the sides given above;
=> x = √36
=> x = 6
Therefore, the value of x after simplification is 6, which when substituted in the given expression will make both the sides equal.

What is the sine for the figure below?
The sine for the right triangle A is 3/5.
The ratio between the side opposite the angle and the triangle's hypotenuse is known as the sine (sin) of an acute angle in a right-angled triangle. A right angle in geometry and trigonometry is an angle that is exactly 90 degrees, or 2 radians, which is equivalent to a quarter turn. If a ray is positioned so that its terminal is on a line and they are equal, the neighbouring angles are right angles.

you can't buy half a fish and rounding up would go over budget so you buy 7 with a little change left over
Answer:
You can only buy 7.

Write the function rule for each function reflected in the given axis.
f(x)=2 x-4 ; x - axis
The given function is f(x) = 2x-4,
We have to find the equation where the reflection of this function is over the x-axis.
There are two types of reflections in general when we talk about functions;
One reflection is over the x-axisThe other is over the y-axis.Now we take an example that we are provided with a point with coordinates (x, y). If we want to reflect it over the x-axis, then the coordinates of this point will become (x, -y). This is because the values of y are negative when we move above the x-axis and positive when we move below the x-axis and vice versa.
The equation to show this is: y = -f(x).
We multiply the entire function, f(x), to find it by a negative. Since f(x) = 2x-4, the transformed function is f(x) = -2x+4.
Therefore, the function rule for the function shown is -f(x).

Answer: x=-1
Step-by-step explanation:

because

over = 3x
4
we can put everything in parentheses and multiply by 4
2x - 10
4( over )= (3x) 4
4
The 4's on the left side will cancel out around and leave
2x - 10
on the right we multiply 3x x 4 which equals 12x
rewrite the equation
2x - 10 = 12x
subtract 2x on each side with the variable.
2x - 10 = 12x
-2x -2x
the 2x's on the left will cancel out.
on the right 12x - 2x equals 10x
now the equation is
-10=10x
but we are not done
divide 10 on each side
on the left -10/ 10 equals -1 because one number is negative and that does not give a postive result.
on the right 10x/ 10 the 10's cancel out leaving the varible x

The x axis (horizontal) and y axis are the two axes that make up a coordinate plane (vertical).The formulae for finding the new coordinates are given by
