√ (x - 7)^2 + (y - 9)^2 = (y - 4)
Answer:
Assuming a vertical axis of symmetry, the equation would be of the form y = ax^2 + bx + c which can also be written as y = a(x - h)^2 + k. Case 1: If the two points have the same y value, then the axis of symmetry will pass through the midpoint of the segment between them.
Step-by-step explanation:
An equation is formed of two equal expressions. The given equation can be simplified for y as y=(x²-14x+114)/10.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The given equation √[(x-7)²+(y-9)²]=(y-4) can be simplified for y as shown below,
[tex]\sqrt{\left(x\:-\:7\right)^2\:+\:\left(y\:-\:9\right)^2}=\left(y\:-\:4\right)[/tex]
(x - 7)² + (y - 9)² = (y - 4)²
(x - 7)² = (y - 4²) - (y - 9)²
(x² + 49 - 14x) = (y² + 16 - 8y) - (y² + 81 - 18y)
x² + 49 - 14x = y² + 16 - 8y - y² - 81 + 18y
x² + 49 - 14x = 10y - 65
x² - 14x + 49 + 65 = 10y
x² - 14x + 114 = 10y
y = (x² - 14x + 114)/10
Hence, the given equation √[(x-7)²+(y-9)²]=(y-4) can be simplified for y as y=(x²-14x+114)/10.

In your own words, name the two operations used for converting weight measurements, and describe when to use each.
What are the 2 operations that you use to convert weight? I'm confused.
Is it multiplying and dividing?
Answer:
In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.Divide the object's weight by the acceleration of gravity to find the mass.

find the 39th term for the aritmethic sequence, 10,15,20
The 39th term of the sequence is 200.
What is Arithmetic Sequence?Arithmetic sequence or arithmetic progression is the set of numbers for which the difference of any two consecutive numbers in that set will be a constant.
The constant term which is the difference of the two consecutive numbers is called the common difference and is usually denoted by 'd'.
Arithmetic sequence is usually represented as
a, a + d, a + 2d, ........, a + (n - 1)d
The nth term of an arithmetic sequence, aₙ is given by the formula,
aₙ = a + (n - 1) d
where, a is the first term and d is the common difference.
The given sequence is 10, 15, 20, ......
a = 10
d = 15 - 10 = 5
Here, we have to find the 39th term of the sequence.
a₃₉ = 10 + (39 - 1) 5
= 10 + (38 × 5)
= 10 + 190
= 200
Hence, the 39th term of the progression 10, 15, 20,..... is 200.

John multiplies one side of the equation 20 + 48 = 68 by a number s. What does he need to do balance the equation?
In order to balance the equation, John should multiply the second side of the equation by s.
Why?
Remember the Golden Rule of Algebra:-
[tex]\bigstar{\boxed{\sf{Whatever~you~do~to~one~side,~you~do~to~the~other.}}[/tex]
So if you multiply 1 side of the equation by s, you multiply the second side by s.

In a certain year, 26% of people aged 65–69 worked. Suppose that a recent report claimed that the percentage of people aged 65–69 who work has increased since that year.
Considering the situation described, the appropriate hypotheses set is given by:
[tex]H_0: p = 0.26[/tex]
[tex]H_1: p > 0.26[/tex]
What are the hypotheses test?
At the null hypotheses, we test if there is not enough evidence that the percentage has increased, that is, it still is of 26%, hence:
[tex]H_0: p = 0.26[/tex]
At the alternative hypotheses, we test if there is evidence that it has increased, hence:

hello, id like to order3 halves of a cupcake for my family plus some extra for my 2 friends.
Answer:
They'll each want a quarter of a cupcake.
Step-by-step explanation:
The number of people in the family is 14.
The number of cupcakes ordered is 4.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Number of cakes for the family = 3 (1/2)
Number of friends = 2
Now,
Each person's amount of cake = 1/4
The number of people in the family.
= 3(1/2) ÷ 1/4
= 7/2 x 4
= 14
The total number of cupcakes ordered.
= 2 x 1/4 +3(1/2)
= 1/2 + 3(1/2)
= 1/2 + 7/2
= 8/2
= 4
Thus,
There are 14 people in the family.
The total number of cupcakes ordered is 4.
