a community center is trying to raise $1680 to purchase exercise equipment. the center is hoping to receive equal contributions from members of the community. write and algebraic expression to determine how much will be needed from each person if n people contribute. Then evaluate the expression for 10, 12, 14, or 16 people.
Lets find f(n) formula

What is Unitary method?"It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
Total money = $225.00
Cost of one ball =$55
So, remaining money after buying the ball
=225- 55
= $170
Now,
game of bowling costs $3.50,
So, number of bowling can be played is
=170/3.5
=48.75
= 48 bowling

1. Assume you took $2,500 in cash out of your savings account and bought a car worth
$2,500. How much did your net worth change?
Answer:
The net worth does not change.
Step-by-step explanation:
Net worth is the sum of all of your assets minus the liabilities.
If you start off with 2,500 in your savings account, then you use the money to buy a car the net worth does not change. You started with a net worth of 2,500 because money in your savings account in considered an asset. You then use that money to buy a car which is an asset, and the car contributes to your net worth.

Find the coordinates of the midpoint of a segment with given endpoints
Answer:
[tex]\boxed {\boxed {\sf ( - \frac{9}{2}, -1) \ or \ (-4.5, -1) }}[/tex]
Step-by-step explanation:
We are asked to find the midpoint of a line segment. When you find the midpoint, you essentially find the average of the x-coordinates and the y-coordinates. The midpoint formula is:
[tex](\frac {x_2+x_1)}{2}, \frac{y_2+y_1}{2})[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the line segment. we are given the endpoints R (-6, 1) and S (-3, -3). If we match the value and the corresponding variable we see that:
x₁= -6 y₁= 1 x₂= -3 y₂= -3Substitute the values into the formula.
[tex]( \frac{-3 + -6}{2} , \frac{ 1+ -3}{2} )[/tex]
Solve the numerators.
-3 + -6 = -9 1 + -3 = -2[tex](\frac {-9}{2}, \frac {-2}{2})[/tex]
Divide.
[tex]( - \frac {9}{2}, -1})[/tex]
The fraction can also be written as a decimal.
[tex](-4.5 , -1)[/tex]
The midpoint of the line segment RS is (-9/2, -1) or (-4.5, -1).

Q9) There are 4,000 students attending a local community college and the number of students is increasing by 5% each year. How many students will attend the college in 4 years?
Answer: 4,862 students will attend the college in the next four years
Step-by-step explanation: If the college starts out with 4,000 students you need to find 5% of 4,000. To do this you would multiply 4,000 by 0.05, you should get 200. So 5% of 4,000 is 200 so the next year there will be 200 more students then last year meaning the next year will have 4,200 student. So now you'll repeat the same step multiply the number of students (now 4,200) by 0.05, then add the answer to the number of students from the previous year. So year two is:
4,200x0.05=210
4,200+210=4,410
repeat these steps till you have four years worth.
I need help with this question x2 - 16y2
Use an equation to describe its intersection with each of the coordinate planes. (If the sphere does not intersect with the plane, enter DNE.)
a. intersection with xy-plane
b. intersection with xz-plane
c. intersection with yz-plane
The question seems to be incomplete. I assume that we have the equation of a sphere, and we want to define equations of the intersection between that sphere and some given planes.
A general sphere of radius R centered at the point (a, b, c) is written as:
(x - a)^2 + (y - b)^2 + (z - c)^2 = R^2
Each of the planes will have a fixed value, to find the intersection, we just need to "fix" that fixed value in the equation above.
a) Intersection with xy-plane
The xy-plane has a z-value of 0 (the x and y values are free) so to write the intersection we only need to fixate z = 0.
Using the general sphere we get:
(x - a)^2 + (y - b)^2 + (0 - c)^2 = R^2
(x - a)^2 + (y - b)^2 + c^2 = R^2
(x - a)^2 + (y - b)^2 = R^2 - c^2
This is a circle, centered at (a, b) in the xy-plane, and with a radius of:
√(R^2 - c^2)
Similarly:
b) intersection with xz-plane
Here we have y = 0, then the equation becomes:
(x - a)^2 + (0 - b)^2 + (z - c)^2 = R^2
(x - a)^2 + b^2 + (z - c)^2 = R^2
(x - a)^2 + (z - c)^2 = R^2 - b^2
c) intersection with yz-plane
Here we have x = 0
(0 - a)^2 + (y - b)^2 + (z - c)^2 = R^2
a^2 + (y - b)^2 + (z - c)^2 = R^2
(y - b)^2 + (z - c)^2 = R^2 - a^2
Finally, in which cases we would write DNE?
Only if the expression at the right (the radius of the circle) are smaller than zero.
For example, if R^2 - a^2 < 0, then the sphere does not intersect the yz-plane.

Given are the slopes of several lines. Indicate whether each line is horizontal, vertical, rises from left to right, or falls from left to right.
Answer:
Rises from left to rightVertical LineHorizontal LineFalls from left to rightStep-by-step explanation:
Keep in mind we read graphs from left to right just like how we read and write.
A positive slope will be increase from left to right. A negative slope with decrease left to right. A vertical line will have a undefined slope.A horizontal line will have a slope of 0.We can use those tips to solve the problem.
Option A:
4/5 is a positive slope so it will rise from left to right.
Option B:
No slope automatically means "undefined" so that falls in the definition of a vertical line.
Option C:
A slope of 0 is defined as a horizontal line.
Option D:
-4/5 is a negative slope so it will fall from left to right.
Best of Luck!

Prove that the line that passes through (8, -1) and (4, -3) is parallel to the line that passes through (-6, -1) and (2, 3).
Answer:
Both lines have the same slope.
Step-by-step explanation:
- If two lines are parallel, they have the same slope. To prove that these, lines are parallel, we have to first find out the slope between points.
Line 1 :y2 - y1 / x2 - x1
-3 - (-1) / 4 - 8
-2/-4
= 1/2
Line 2 :y2 - y1 / x2 - x1
3 - (-1) /2 - (-6)
4/8
= 1/2
Both the lines have the same slope meaning they are parallel.

The answer is Either B or C, But I'm going with ASA which is B.
explanation: congruent angles are about 48° they could be much more higher but in this case they aren't. And as you could see congruent angles aren't like that.
The rule is If two angles have the same measure then they are congruent.
Congruent angles are marked with the same number of "arcs".
Note: This picture isn't mine, it's an example of what a congruent angle could look like.

The derivative of (x^2 +1)(x^3+ 1) (by definition and basic rule)
Answer:
f'(x) = 5x^4 + 2x + 3x^2
Step-by-step explanation:
To find the derivative of this equation we can do two things.
One method is to use the product rule, which states that when f(x) consists of two functions multiplied to each other (meaning f(x) = g(x) * h(x)), the derivative is f'(x) = g'(x)*h(x) + g(x)*h'(x). In simple language, the derivative is found by finding the derivative of x² + 1 and multiplying it with the normal function of x³ + 1, after which you add the product of the nnormal function of x² + 1 and the derivative of x³ + 1.
it might be clearer when I show you:
[tex]f(x) = (x^2 + 1)(x^3 + 1)\\f'(x) = (2x)(x^3 + 1) + (x^2 + 1)(3x^2)\\Simplify:\\f'(x) = 2x^4 + 2x + 3x^4 + 3x^2 = 5x^4 + 3x^2 + 2x\\[/tex]
If you are not familiar with this rule you can first write out the function and then use the basic rule:
[tex]f(x) = (x^2 +1)(x^3+1) = x^5 + x^2 + x^3 + 1\\f'(x) = 5x^4 + 2x + 3x^2[/tex]
If you need any further help please say so in the comments! I hope this helps! If the steps seem complicated, I suggest you could revise expanding brackets (the first step of the second method) and the basic rules of deriving, but feel free to reach out if you struggle afterwards still
