Determine if this series converges or diverges. Find the sum if possible. 250, 50, 10...
Answer:
50
Step-by-step explanation:
Answer:
312.5
Step-by-step explanation:
We have the series: 250, 50, 10...
As we can see, each subsequent term gets smaller and smaller. Eventually, it will be infinitesimally small. So, our series converges.
We can also see this from our common ratio. Each term is 1/5 of the previous term. Since our r 1/5 is less than 1, our series will converge.
Since it converges, we can indeed find our sum. First, we can write our series using summation. This will be:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }[/tex]
We can use the following infinite geometric series formula:
[tex]\displaystyle{\sum_{n=0}^{\infty} ar^n=\frac{a}{1-r}[/tex]
So, let's substitute 250 for a and 1/5 for r. This yields:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=\frac{250}{1-\frac{1}{5}}[/tex]
Subtract:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=\frac{250}{\frac{4}{5}}[/tex]
Divide. So, our series converges to:
[tex]\displaystyle{\sum_{n=0}^{\infty} 250(\frac{1}{5})^n }=312.5[/tex]
And we're done!
What is the midpoint between the ordered pairs (10,-4) and (-9, 11)?
0 (0.5,3.5)
O (10.5,3.5)
O (-0.5, -0.5)
O (-10.5, -0.5)
Answer:
The answer would be (-0.5, -0.5)
Step-by-step explanation:
This is because when you solve for a mid-point you it's like solving for an average. You would take x1 and x2 and you would find the difference between them. Which would be -0.5. You do the same with y1 and y2. Which would be 3.5.
Thomas bought a DVD for $14.50, a music CD for $10, and a computer game for $48. If the sales tax rate is 8%, what is the total cost of Thomas’ purchases to the nearest cent?
Answer:
78.03
Step-by-step explanation:
14.50 + 10 + 48 = cost
cost = 72.25
tax = 5.78
total cost = cost + tax
total cost = 78.03
what is the slope for a line that is parallel to the line y=2/5x-4
Answer:
2/5
Step-by-step explanation:
The slope of the line
y=2/5x-4
is 2/5 since it is in the form y = mx+b where m is the slope
Parallel lines have the same slope so a line that is parallel to y=2/5x-4 has a slope of 2/5
Write a quadratic function in standard form with zeros -4 and -3
Answer:
y = x² + 7x + 12
Step-by-step explanation:
Given the zeros x = - 4 and x = - 3, then the corresponding factors are
(x - (- 4) ) and (x - (- 3) ), that is
(x + 4) and (x + 3)
The function is then the product of its factors
y = (x + 4)(x + 3) ← expand using FOIL
= x² + 7x + 12

C) x = - 2
D) y = 7
Answer:
D) y= 7
Step-by-step explanation:
y = 7 is the equation of the line that passes through the point ( -2, 7 ) and has a slope of zero.
Step-by-step explanation:
Given:
Let,
A ≡ ( x1 , y1 ) ≡ ( -2, 7 )

The weekly revenue for a company is r=−3p2+70p+102, where p is the price of the company's product. Use the discriminant to find whether there is a price for which the weekly revenue would be $1500.
Step-by-step explanation:
$1500 = 3p^2 + 70p + 102
0 = 3p^2 + 70p - 1398
0 = (x=12.87 or x=-36.2)
What is the point slope form
Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Step-by-step explanation:
Answer: y - 2 = -6/5(x - 0)
You use the equation (y - y1) = m(x - x1)
Where y1 and x1 are coordinates of a point on the equation.
If the y intercept is 2, then the point (0, 2) is on the equation.

There are 100 bolts in 5 bookcases. What is the unit rate in bolts per bookcase?
Answer:
20/1
Step-by-step explanation:
The unit rate in bolts per bookcase is 20bolts per bookcase
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We are Given that 100 bolts in 5 bookcase
We need to find the unit rate in bolts per bookcase
Number of bolts in 5 bookcases= 100
Number of bolts in 1 bookcases= 100/5
= 20
So, it will be 20 bolts everyday
Thus, the unit rate is 20bolts/sec

What is an equation of the line that passes through the points (-6,5) and (6,7)
Answer:
y = 1/6 x + 6
Step-by-step explanation:
m = (y2-y1)/(x2-x1)
m = (7-5)/(6-(-6))
m = 2/12 = 1/6
Substitute x and y values with a pair of coordinates,
y = mx+c
7 = 1/6(6) + c
7 = 1 + c
c = 6
Thus, the equation is y = 1/6 x +6

Step-by-step explanation:
How do you solve a simple equation?
Answer:
Solving Simple Equations
When solving a simple equation, think of the equation as a balance, with the equals sign (=) being the fulcrum or center. Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing to both sides of the equation (say, adding 3 to each side) keeps the equation balanced.
Solving an equation is the process of getting what you're looking for, or solving for, on one side of the equals sign and everything else on the other side. You're really sorting information. If you're solving for x, you must getx on one side by itself.
Step-by-step explanation:
Addition and subtraction equations
Some equations involve only addition and/or subtraction.
Example 1
Solve for x.
x + 8 = 12
To solve the equation x + 8 = 12, you must get x by itself on one side. Therefore, subtract 8 from both sides equation
X+8=12
- 8 - 8
_____ _____
X = 4
To check your answer, simply plug your answer into the equation:
X+8=12
(4)+8=12
12=12

Eduardo drew a scale drawing of the school cafeteria. He used a scale of 1 inch: 6 feet. In the drawing, the width of the cafeteria is 9 inches long. What is the actual width of the cafeteria?
Answer:
54 feet
Step-by-step explanation:
the answer is 54 feet because the ratio of 1:6 is equal to 9:54.
Multiply both sides of your original ratio (1:6) by nine. 1x9=9 and 6x9=54.
