Answer:
(-1,5) and [tex](3, \frac{1}{125})[/tex] are points on the graph
Step-by-step explanation:
Given
[tex]g(x) = \frac{1}{5}^x[/tex]
Required
Determine which point in on the graph
To get which of point A to D is on the graph, we have to plug in their values in the given expression using the format; (x,g(x))
A. (-1,5)
x = -1
Substitute -1 for x in [tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^{-1}[/tex]
Convert to index form
[tex]g(x) = 1/(\frac{1}{5})[/tex]
Change / to *
[tex]g(x) = 1*(\frac{5}{1})[/tex]
[tex]g(x) = 5[/tex]
This satisfies (-1,5)
Hence, (-1,5) is on the graph
B. (1,0)
x = 1
Substitute 1 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^1[/tex]
[tex]g(x) = \frac{1}{5}[/tex]
(1,0) is not on the graph because g(x) is not equal to 0
C. [tex](3, \frac{1}{125})[/tex]
x = 3
Substitute 3 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^3[/tex]
Apply law of indices
[tex]g(x) = \frac{1}{5} * \frac{1}{5} * \frac{1}{5}[/tex]
[tex]g(x) = \frac{1}{125}[/tex]
This satisfies [tex](3, \frac{1}{125})[/tex]
Hence, [tex](3, \frac{1}{125})[/tex] is on the graph
D. [tex](-2, \frac{1}{25})[/tex]
x = -2
Substitute -2 for x
[tex]g(x) = \frac{1}{5}^x[/tex]
[tex]g(x) = \frac{1}{5}^{-2}[/tex]
Convert to index form
[tex]g(x) = 1/(\frac{1}{5}^2)[/tex]
[tex]g(x) = 1/(\frac{1}{5}*\frac{1}{5})[/tex]
[tex]g(x) = 1/(\frac{1}{25})[/tex]
Change / to *
[tex]g(x) = 1*(\frac{25}{1})[/tex]
[tex]g(x) = 25[/tex]
This does not satisfy [tex](-2, \frac{1}{25})[/tex]
Hence, [tex](-2, \frac{1}{25})[/tex] is not on the graph

Emily has driven 600 miles so far on her way to the beach. If her total trip will be 850 miles‚ about what percentage of the drive does she have left to complete? a) 15% b) 29% c) 40% d) 73%
Answers
Answer:
B) 29%
Step-by-step explanation:
First, we subtract 600 from 850 to get the distance she has left. 850 - 600 = 250. Next, we take 250 and divide it by 850 to get the decimal which is 0.294117647. We can round this answer to 0.29 and convert this answer to a percentage which is 29%.
Answer:
B. 29%
Step-by-step explanation:
Percentages can be found by dividing the part by the whole, then multiplying by 100.
(part/whole) * 100
We have to find the percentage of the drive she has left.
Therefore, the part is the miles she has left and the whole is the total trip.
(miles left/total trip) * 100
First, we need to find how many miles she has left. We must subtract the miles she has driven from the total trip.
total - miles driven
She has 850 total miles and has driven 600 miles.
850-600
250
She has 250 miles left.
Now we know the miles she has left.
(miles left/total trip) * 100
miles left = 250
total trip= 850
(250/850) * 100
Solve inside the parentheses first. Divide 250 by 800.
(0.29411765)*100
Multiply
29.411765
Round to the nearest whole number. The 4 in the tenth place tells us to leave the whole number as is.
29
Therefore, she has about 29% of her trip left.
Camillo used the calculations shown to determine how much he would spend on 2,400 oz of jelly. 48 ounces of jelly costs 3 collars and 84 cents.

To find the error in Camille's calculation
(48/$3.84)(?/s1)
48x/3.84
=$13.79
We will divide 48 ounces of jelly by $13.79 to get the rate

Answer:
3.43
Step-by-step explanation:
To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
Answer:
3.44 units^2
Step-by-step explanation:
Area of a square = l * w
Area of a circle = 3.14 * r^2
Area of semicircle = 3.14 * r^2 * 1/2
Area of shaded region: Area of square - Area of 2 semicircles
Area of square => 4 * 4 = 16
Area of both semicircles => (3.14 * r^2 * 1/2)*2 = 12.56
16 - 12.56 = 3.44
3.44 units^2 is the answer

Answers
Answer:
Hope this helps
Step-by-step explanation:
For part A, we want two inequalities that have F and D as solutions, but none of the other points. The easiest way to do this is construct two lines that pass through the origin, and then figure out which way the inequalities need to face based on the points we want to include. Our lines will be:
The first line intersects F and the second line intersects D, so we need to figure out which way to point the inequalities so both include the point they do not intersect:
So our system is:
Part B: To verify, plug in the x and y values for D and F and verify that it creates true statements in the system.
Part C: You can plug in the different x, y values for the points. The points which create true statements identify farms where chickens can be raised, while those which create false statements cannot raise chickens.

1) There are 26 letters in the alphabet. Thus, 27 people must be chosen because otherwise there could be 1 person per initial.
2) There are 7 days in a week. Thus, if the first 7 had their birthdays on every day of the week, the 8th person must share a birthday on the same day of the week as another.
3) A phone number can contain 0,1,2,3,4,5,6,7,8,9. Thus, if the first 10 people have a phone number that ends with each digit, the 11th must share it, as there are no unique options.
4) 100/2 = 50. Thus, the minimum each bag could have is 50.
5) 19/3 > 6. The maximum number you could get with numbers less than seven is 6,6,6 = 18. 18<19. Thus, you need a number 7 or greater.
6) The worst scenario that could happen here is that you grab 8 German books, 10 French books, and 12 Spanish, Russian and Italian books. This would be 54 books. Thus, with the 55th book, you must have gotten 12 of at least one subject. Thus, the answer is 55 books.
7) This is vague. If she cannot repeat any of the three jokes in the triplet, then she must have 36 jokes for this to be possible, because 12*3=36
8) Each of the remaining 29 students made less than 12 mistakes. Even if 2 students made 11,10,9,8,7,6,5,4,3,2,1 mistakes, there would still be multiple students left that would have made 11,10,9,8,7,6,5,4,3,2, or 1 mistake(s), meaning that at least 3 students made the same amount of mistakes.
9) 465/95 = about 4.9. Thus, each table could have less than 6 seats, so we cannot be sure.

Bags contain x and y numbers of marbles.
x + y > 100
The least number that is more than 100 is 101.
If x and y are both less than 51, then you have at most a total of 100 marbles.
To have 101 marbles, you must have one bag with at least 51 marbles, and the other bag with the rest. Neither bag must have at least 50 marbles. You can have 1 and 100, but that is still more than 50 marbles in one bag.

You are looking for 12 books in the same language. Let's say you start by picking all 10 French books and all 8 German books. You are up to 18 books. There are no more French or German books, so you can't get to 12 books in one language with those. Now you pick 11 Spanish books, 11 Russian books, and 11 Italian books. That is another 33 books, and still no 12 books in one language. You already picked 18 books + 33 books = 51 books. The very next book must be a Spanish book or a Russian book or an Italian book, and it will make the 12th book of that language. You need to pick 52 books to be sure you have 12 of the a single language.
Answer: 52 books

You need enough jokes to have 12 different combinations of 3. This is a case in which order does not matter.
If you have 3 jokes, named A, B, and C, you only have enough for 1 year, since ABC, ACB, BAC, BCA, CAB, and CBA are all the same triple of jokes.
This is a combination problem.
nCk = (n!)/[k!(n - k)!]
We know we need more than 3 jokes. Let's try 4.
n = 4
nCk = (4!)/[3!(4 - 3)!]
nCk = 4
We need 12, so 4 is not enogh.
n = 5
nCk = (5!)/[3!(5 - 3)!]
= 5 * 4/2
= 10
Now enough.
Try n = 6
nCk = (6!)/[3!(6 - 3)!]
= 20
With 6 different jokes, you can make 20 different triplets, so there is no need to repeat any triplet in 12 years.

Which equation represents the vertical asymptote of the graph? a curve asymptotic to y equals 0 from negative x to negative y near x equals 12. A curve asymptotic to y equals 0 from positive x to positive y near x equals 12. x = 0 y = 0 x = 12 y = 12
Answers
Answer:
The correct option is x = 12
Step-by-step explanation:
An asymptote of a function is a line to to which the function converges to as it tends to infinity such that the function gets infinitesimally close to its asymptote but the function will not reach or cross its asymptote. That is the separating distance between the function and the asymptote tends to zero as either the x or y coordinates, or both the x and y coordinates tend to infinity.
A vertical aymptote, is one parallel to the y-axis and it is given by the value of the x-coordinate where it occurs
In the graph of the question, the vertical asymptote occurs at x = 12 and it is the line x = 12.
From the given graph, it can be said that the vertical asymptote will be formed at x=12. Option C is correct.
The given curve represents a function which is defined for all value fo x except 12.
The following information can be extracted from the graph of the function;
The function is defined for all values of x except 12.The function has a horizontal asymptote at y=0.The function forms a vertical asymptote at x=12. The curve approaches negative infinity from the left of 12 and approaches positive infinity from right of 12.Based on the above conclusions, it can be said that the vertical asymptote will be formed at x=12. Option C is correct.

Step-by-step explanation:
The summation symbol ...
[tex]\sum\limits_{n=1}^{104}{\text{expression}}[/tex]
means that the expression is evaluated for n=1, n=2, n=3, n=4, ... up to n=104 and all of those are added together. Here, the expression being evaluated is "6", which does not depend on n. So, this is simply the sum of 104 instances of 6:

HALP PLS 1000 students are arranged in several rows (more than 16). The numbers of students in each row are consecutive positive integers. How many students are there in the first row? (A) 20 (B) 25 (C) 28 (D) 44 (E) 80
Answers
Answer:
The correct option is;
(C) 28
Step-by-step explanation:
The information given are that;
The total number of students = 1000
The number of students in each row are consecutive positive numbers
Let the number of students in the first row be x,
Let the number of rows be 17
We have;
The number of students in the last row = x + 16
The number of students in the penultimate row = x + 15, we continue to get;
n×x + n/2×(n-1) = 1000
(The term n/2×(n-1) is from the sum of an arithmetic progression formula)
Which gives;
17×x + 17/2×16 = 1000
17×x = 1000 - 17/2×16 = 1000 - 136 = 864
x = 864/17 = Which is not an integer,
We continue checking till we get to 25 rows which gives;
25×x + 25/2×24 = 1000
25×x + 300 = 1000
25×x = 1000 - 300 = 700
x = 700/25 = 28
The number of student in the first row = 28 students.
