which function defines (f divided by g)(x)
Answer:
A if its wrong im sorry
Step-by-step explanation:
The function is (f ÷ g) (x) is given as [tex](3.6)^{-2x + 1}[/tex]. Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The functions are given as
[tex]\rm f(x) = (3.6)^{x + 2}\\\\\\g(x) = (3.6)^{3x + 1}[/tex]
The f(x) is divided by the g(x), we have
[tex]\rm (f \div g ) (x) = \dfrac{f(x)}{g(x)} = \dfrac{(3.6)^{x + 2}}{(3.6)^{3x + 1}}\\\\\\(f \div g ) (x) = (3.6)^{x + 2}*(3.6)^{-(3x + 1)}\\\\\\(f \div g ) (x) = (3.6)^{x + 2- 3x - 1}\\\\\\(f \div g ) (x) = (3.6)^{-2x + 1}[/tex]

What is the domain of the relation graphed below?
Answer:
Domain: {-5, -4, -3, 1, 2, 5}
Step-by-step explanation:
Recall:
Domain = inputs (x-values)
Range = outputs (y-values)
All set of x-values (input) of the points that are plotted on the graph make up the domain of the relation.
Thus, they are:
Domain: {-5, -4, -3, 1, 2, 5}
A graphing calculator is recommended. A bacteria culture starts with 300 bacteria and doubles in size every half hour. (a) How many bacteria are there after 2 hours? bacteria (b) How many bacteria are there after t hours? y = bacteria (c) How many bacteria are there after 40 minutes? (Round your answer to the nearest whole number.)
Answer:
a) 4800 bacteria
b) [tex]y(t) = 300(4)^t[/tex]
c) 754 bacteria
Step-by-step explanation:
A bacteria culture starts with 300 bacteria and doubles in size every half hour.
This means that the number of bacteria after t periods of half hour is given by:
[tex]y(t) = 300*(2)^{t}[/tex]
(a) How many bacteria are there after 2 hours?
2 hours is 2*60/30 = 4 periods of 2 hours, so this is y(4).
[tex]y(4) = 300*(2)^{4} = 300*16 = 4800[/tex]
(b) How many bacteria are there after t hours?
It doubles every half hour, so each hour, it is multiplied by 4. Then
[tex]y(t) = 300(4)^t[/tex]
(c) How many bacteria are there after 40 minutes?
40 minutes is 40/30 = 1.33 periods of half hour. So this is y(1.33).
[tex]y(1.33) = 300*(2)^{1.33} = 754[/tex]

Sanjay, Ajay and Anushka are employees of a company that has branches in Chennai, Bangalore and Mumbai. The company sends each of them to one of these cities at random. Let X X be a random variable that denotes the number of employees assigned to their favourite cities. If Chennai, Bangalore and Mumbai are the favourite cities of Sanjay, Ajay and Anushka, respectively, then find the possible values of X.
a. X= {0,1,2}
b. X= {0,1,2,3}
c. X= {0,1,3}
d. X= {0,[infinity]}
Answer:
c. X= {0,1,3}
Step-by-step explanation:
We have these possible outcomes:
None assigned to their favorite cities.
One assigned to their favorite city(The other two are assigned to the other's favorite city).
All are assigned to their favorite city.
Why is two not possible?
If two peooke are assigned to their favorite city, the third person necessary has to be assigned to their favorite city, as it will be the only option remaining.

The school play earned $11,271 in ticket sales. If the cost of each ticket was $13, how many tickets were sold?
Answer:
867 tickets were sold because if you divide how much they earned by how much it cost you get 867
Answer:
867 Tickets
Step-by-step explanation:
Divide $11,271 by the number of the ticket cost $13.
11,271/13= 867
from the set 1/2/3/4/5 which values make the inequality n + 1 > true?
Hi there!
To make n+1>4 true, you must have n be a numebr greater than 3...
The reason why is because if it is less than 3 or 3, it’ll have to be <.
The two numbers that can make this equation true is 4 and 5...

Consider the diagram and the paragraph proof below.
Given: Right △ABC as shown where CD is an altitude of the triangle
Prove: a2 + b2 = c2
Triangle A B C is shown. Angle A C B is a right angle. An altitude is drawn from point C to point D on side A B to form a right angle. The length of C B is a, the length of A C is b, the length of A B is c, the length of A D is e, the length of D B is f, and the length of C D is h.
Because △ABC and △CBD both have a right angle, and the same angle B is in both triangles, the triangles must be similar by AA. Likewise, △ABC and △ACD both have a right angle, and the same angle A is in both triangles, so they also must be similar by AA. The proportions StartFraction c Over a EndFraction = StartFraction a Over f EndFraction and StartFraction c Over b EndFraction = StartFraction b Over e EndFraction are true because they are ratios of corresponding parts of similar triangles. The two proportions can be rewritten as a2 = cf and b2 = ce. Adding b2 to both sides of first equation, a2 = cf, results in the equation a2 + b2 = cf + b2. Because b2 and ce are equal, ce can be substituted into the right side of the equation for b2, resulting in the equation a2 + b2 = cf + ce. Applying the converse of the distributive property results in the equation a2 + b2 = c(f + e).
Which is the last sentence of the proof?
Because f + e = 1, a2 + b2 = c2.
Because f + e = c, a2 + b2 = c2.
Because a2 + b2 = c2, f + e = c.
Because a2 + b2 = c2, f + e = 1.

How do you work 6x²-2=11x
Answer:
Step-by-step explanation:
Please be specific: "How do you solve 6x^2 - 2 = 11x?"
Rewrite this in terms of descending powers of x: 6x^2 - 11x - 1 = 0.
Use the quadratic formula to find the roots. Here the coefficients are a = 6, b = -11 and c = -1. Then the discriminant b^2 - 4ac becomes 121 - 4(6)(-1) = 121 + 24 = 145, and so the roots are:
-(-11) ± √145 11 ± √145

[tex]\frac{7}{2}[/tex]
Step-by-step explanation:
Slope, or the Rise/run formula is typically used on the coordinate plane to figure the equation of a line. Although we are not given the direct image, we can still determine the slope by using the following formula:
[tex]slope=\frac{rise}{run} =\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\=\frac{12-5}{3-1} \\=\frac{7}{2} \\slope=\frac{7}{2}[/tex]

Volume of a cylinder is given as V = πr²h
Where,
radius (r) = 6 cm
height (h) = 8 cm
Plug in the values
V = π*6²*8
V = π*36*8
V = π*288
V = 288π cm³ or 904.78 cm³
An advertising agency notices that approximately 1 in 50 potential buyers of a product ssees a given magazine ad, and 1 in 5 sees a corresponding ad on television. One in 100 see both. One in 3 actually purchases the product after seeing the ad, 1 in 10 without seeing it. What is the probability that a randomly selected potential customer will purchase the product
Answer:
0.1490 = 14.90% probability that a randomly selected potential customer will purchase the product.
Step-by-step explanation:
Probability of seeing the ad:
I am going to find this probability using Venn Sets.
I am going to say that:
Event A: Sees a magazine ad.
Event B: Sees a television ad.
Approximately 1 in 50 potential buyers of a product sees a given magazine ad
This means that [tex]P(A) = \frac{1}{50} = 0.02[/tex]
1 in 5 sees a corresponding ad on television.
This means that [tex]P(B) = \frac{1}{5} = 0.2[/tex]
One in 100 see both.
This means that [tex]P(A \cap B) = \frac{1}{100} = 0.01[/tex]
The probability of seeing the ad is the probability of seeing at least one of those(magazine or tv), which is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]. So
[tex]P(A \cup B) = 0.2 + 0.02 - 0.01[/tex]
[tex]P(A \cup B) = 0.21[/tex]
Probability of purchasing the product.
0.21 = 21% of customers see the add. Of those, 1/3 = 0.3333 buy the product.
1 - 0.21 = 0.79 = 79% of customers dont see the add. Of those, 1/10 = 0.1 buy the product. So
[tex]p= 0.21*0.3333 + 0.79*0.1 = 0.1490[/tex]
0.1490 = 14.90% probability that a randomly selected potential customer will purchase the product.
