Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?
(x – 9)2 + (y + 4)2 = 25
(x + 4)2 + (y – 9)2 = 25
(x – 9)2 + (y + 4)2 = 100
(x + 4)2 + (y – 9)2 = 100
Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
Data
h = -4k = 9r = diameter/2 = 10/2 = 5Equation of CircleThe equation of circle is given by
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our values and get our equation
[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]
we substituted the values of h and k and made sure it's in the standard form of equation of a circle.
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
This looks exactly like
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.
How far, in metres, is it from my home to my school?
Given:
I have walked 20% of the way to school.
I have 1200 metres more to walk than when I have 20% of the walk remaining.
To find:
The distance from home to school.
Solution:
Let x be the distance from home to school.
I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.
It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.
[tex]1200=\dfrac{60}{100}x[/tex]
[tex]1200=0.6x[/tex]
[tex]\dfrac{1200}{0.6}=x[/tex]
[tex]2000=x[/tex]
Therefore, the distance from home to school is 2000 metres.
How far, in metres, is it from my home to my school is 2,000 metres.
First step is to formulate
1200/(1-2×20%)
Second step is to find how far in metres
Distance=1200/(1-0.4)
Distance=1200/0.6
Distance=2,000
Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.

A performing arts group has 23 members and adds 2 members per
month. Write an equation in slope-intercept form to represent the number
of members y in x months.
y=2x+23
2x is the for the number of people added every month and 23 is for the number you start with
The equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
In slope-intercept form, an equation of a line is represented as y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (or the point at which the line crosses the y-axis).
Let's represent x is the number of months and y is the number of members.
The number of members y in x months is a linear function of the number of months, with a slope of 2 (the number of members added per month) and a y-intercept of 23 (the number of members at the beginning).
Thus, the equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23

You are driving to visit a friend in another state who lives 700 miles away. You are driving 65miles per hour and have already driven 375 miles. Write and solve an equation to find how much longer in hours you must drive to reach your destination.
Answer:
5 hours
Step-by-step explanation:
distance = rate x time
t = time
(700-375) = 65t
325 = 65t
325/65 = t
5 hours = t
Mia walks up to a claw machine with a pocket full of quarters. She spends them at a rate of two every minute until she runs out.
Part A
If the number of quarters Mia has is graphed over time, which feature of the graph corresponds to the rate at which Mia spends the quarters?
A. the x-intercept
B. the slope
C. the y-intercept
D. the minimum value
Part B
What is the slope?
A. 2
B. 60
C. −60
D. −2
part a
The x-intercept
part b

The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
And, The value of slope will be 2.
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
She spends them at a rate of two every minute until she runs out.
Now,
Since, She spends them at a rate of two every minute until she runs out.
And, The number of quarters Mia has is graphed over time.
We know that;
Usually we represent the independent variable (time) by x and dependent variable (quarters) by y.
Hence, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
So, The slope = 2/1
= 2
Thus, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters. And, The value of slope will be 2.

answer for brainlest and 25 points
Answer:
Order from greatest to least: 10.5, [tex]3\pi +1[/tex], [tex]\sqrt{105}[/tex]
Step-by-step explanation:
step 1 simplify each number
3π + 1 = 10.4247779
*round to the nearest tenth*
3π + 1 = 10.4
[tex]\sqrt{105} =10.2469507[/tex]
*round to the nearest tenth*
[tex]\sqrt{105} =10.2[/tex]
10.5 = 10.5
Now that we have simplified each number we can easily put them in order from greatest to least
10.5 is the greatest number
10.4 is the middle number
10.2 is the lowest number
so 10.5, 10.4, 10.2
Now we put them back in the original form
10.5 = 10.5
10.4 = 3π + 1
10.2 = [tex]\sqrt{105}[/tex]
Your answer is
10.5 , 3[tex]\pi[/tex] + 1, [tex]\sqrt{105}[/tex]

multiply. write your answer as a fraction in simplest form: 4 x 5/14
Answer:
Most simplified version is 1 3/7
Step-by-step explanation:
First step is turn everything into a fraction 4 into a fraction is 4/1
4/1 times 5/14 is 20/14 or 1 and 6/14 or 1 and 3/7
Here we have a problem with the multiplication of fractions.
We will find that:
[tex]4 \cdot\frac{5}{14} = \frac{10}{7}[/tex]
First, two things we need to remember:
[tex]\frac{x}{y} \cdot\frac{a}{b} = \frac{x \cdot a}{y \cdot b}[/tex]
Also, an integer number N can be written as:
[tex]N = \frac{N}{1}[/tex]
Now we want to solve:
[tex]4 \cdot\frac{5}{14}[/tex]
Using the above relations we get:
[tex]4 \cdot\frac{5}{14} = \frac{4}{1} \cdot\frac{5}{14} = \frac{4 \cdot5}{1 \cdot14} = \frac{20}{14}[/tex]
Now we need to simplify this, to do it, we need to divide both numerator and denominator by the same number.
We can see that both are multiples of 2, so if we divide both by 2 we get:
20/2 = 10
14/2 = 7
Then we have:
[tex]\frac{20}{14} = \frac{10}{7}[/tex]
Now 7 and 10 do not have common factors, so we can't simplify it anymore.
Concluding, we get:
[tex]4 \cdot\frac{5}{14} = \frac{10}{7}[/tex]
