Answer:
12.6 = c
Step-by-step explanation:
The Pythagorean therom is a^2 + b^2 = c^2
We already know 2 varibles (12 and 4) so we can just plug them in.
12^2 + 4^2 = c^2
144 + 16 = c^2
160 = c^2

Find two positive numbers whose product is 192 and their sum is a minimum.
Answer:
8√3
Step-by-step explanation:
Let a, b = the positive numbers, and the sum = s,
(1)---- ab = 192
(2)--- a + b = s
Since we want to find the minimum sum, we'll have to substitute one of the variables (either a or b) from (1) to (2), I'll choose b,
From (1), b = 192/a
Substitute b = 192/a into (2),
s = a + 192/a
Now, we are able to use a concept of calculus (maximum & minimum) to solve it, just remember 2 steps in finding the values of x in maxima minima question:
1) find dy/dx
2) Find x from dy/dx = 0
ds/da = 1 - 192/a²
When ds/da = 0,
1 - 192/a² = 0
a² = 192
a = ±√192
a = 8√3 , -8√3
Since a is positive, a = 8√3
Substitute a into (1),
b = 192/(8√3)
b = 8√3
Therefore, the two positive numbers are 8√3... and 8√3

probability to draw conclusions about the
likelihood that something will occur?
(Probability)
The closer the probability is to 1, the more likely it is to occur and the closer the probability is to 0, the less likely it is to occur.
ProbabilityThis is the likelihood that an event will occur.
Probability of an event occuring is calculated thus P(event) = event space/sample space.The event space is the set of desired outcomes in which the event can occur while the sample space is the set of all possible outcomes.Now, the probability P(x) of an event x is in the range 0 ≤ P(x) ≤ 1 where P(x) = 0 implies that the event cannot occur and P(x) = 1 implies that the event will definitely occur.To draw conclusions about the likelihood that something will occurFor an event will occur, it value must be close to 1. For example, a probability P(x) = 0.38 is less likely to occur than a probability P(x) = 0.78.So, the closer the probability is to 1, the more likely it is to occur and the closer the probability is to 0, the less likely it is to occur.

Answer:
The answer should be 15, since each week the number goes up by 15.
I see a pattern here! Let me show you - multiply 15 by the week number (1, 2, 3, 4, ...), and you have y.
For example, 15 x 3 (for week 3) is 45, as shown by the y value.
So all we must do is multiply 15 by 5, and voila! We'll have our answer. Which, by the way, is 75.

2x+x+0.3x=99
2.3x=99
x=43.04
The age of the guy is 29.72 years, the age Gerald is 59.44 years and the age of gill is 9.8 years.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given data in the question,
The equation according to the given statement will be,
The age of Gerald is 2x,
The age of the guy is x and the age of the gill is 0.33x.
So, the equation will be,
x + 2x + 0.33x = 99
3.33x = 99
x = 99/3.33
x = 29.72
Age of Gerald, 2x = 2(29.72) = 59.44 years.
Age of guy, x = 29.72 years and,
Age of gill, 0.33x = 0.33(29.72) = 9.8 years.

Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x?
y=4+x
y = x − 4
y = 4 · x
y = x ÷ 4
Answer:y=4+x
Step-by-step explanation:
You are adding gallons not *,/,-,. So it's y=4+x.
The required equation is y = 4 + x. The correct answer would be an option (A).
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Jayne stopped for gas before embarking on a road trip. There were already 4 gallons of gas in the tank.
As per the question, the required equation would be as:
y = 4 + x
This equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x. The total amount of gasoline in the tank, y, is equal to the number of gallons that she put in the tank, x, plus the 4 gallons that were already in the tank.

What is the smallest number which is reversed when 2 is added to its double?
Answer:
25
Step-by-step explanation:
Let the number be 10x+y.
So we have 2(10x+y)+2 = 10y+x, or
20x + 2y + 2 = 10y+x, or
19x=8y-2 …(1)
Try different values of x which satisfy (1) giving an integer value of y. Moreover x should be less than y. The only value of x is 2 which gives us y = 5.
So y = 5 and x = 2.
And the answer is 25.
We can prove this by simply doing the question's equation:
50(since it's the double of 25) + 2 =
50+2= 52

Answer:
100(2)^h=6,400
Step-by-step explanation:
Explanation:
For an equation in the form A(b)^x=y, A represents the initial amount, and b represents the growth rate. At 0 hours, there were 100 cells, so A=100.
Between 0 hours and 1 hour, the number of cells doubled from 100 to 200, or 100(2). Between 1 and 2 hours, the number of cells again doubled from 200 to 400, or 100(2)^2. So the growth rate, or b, is 2.
The table shows that at h hours, there were 6,400 cells. Therefore, the equation that represents the number of cells at h hours is .100(2)^h=6,400

Transform the table below given that g(x) = 2 f(6x).+ 8. Enter your answers as reduced fractions if necessary. Make sure your answers line up vertically with the corresponding x and f(x) values. As a hint, you can consider y f(x) to be the base graph of g(x).
The function g(x) = 2f(6x) + 8 is a function transformation of the function f(x)
How to transform the table?The function g(x) is given as:
g(x) = 2f(6x) + 8
The table is not given.
So, I will provide a general explanation
Using the following values of x:
x = 0, 1, 2, 3......
We have:
g(0) = 2f(6 *0) + 8
g(0) = 2f(0) + 8
g(1) = 2f(6 *1) + 8
g(1) = 2f(6) + 8
g(2) = 2f(6 *2) + 8
g(2) = 2f(12) + 8
g(3) = 2f(6 *3) + 8
g(3) = 2f(18) + 8
Next, we assume the following values
f(0) = 4, f(6) = 5; f(12) = 6 and f(18) = 7
The values become:
g(0) = 2f(0) + 8 = 2 * 4 + 8 = 16
g(1) = 2f(6) + 8 = 2 * 5 + 8 = 18
g(2) = 2f(12) + 8 = 2 * 6 + 8 = 20
g(3) = 2f(18) + 8 = 2 * 7 + 8 = 22
So, the table of values would be:
x g(x)
0 16
1 18
2 20

[tex]x = 6y + 7[/tex]
[tex]x = 6(0) + 7[/tex]
[tex]x = 0 + 7[/tex]
[tex]x = 7[/tex]
Answer:
y = 0
x = 7
Step-by-step explanation:
2x − 9y = 14 ⇒ ( 1 )
x = − 6y +7 ⇒ ( 2 )
First, let us find the value of y.
For that, replace x with ( - 6y + 7 ).
Let us take equation 1 for that.
2x − 9y = 14
2 ( - 6y + 7 ) - 9y = 14
-12y + 14 - 9y = 14
21y = 14 - 14
21y = 0
Divide both sides by 21.
y = 0
And now let us take equation 2 to find the value of x by replacing y with 0.
2x − 9y = 14
2x - 9 × 0 = 14
2x - 0 = 14
2x = 14
Divide both sides by 2.
x = 7
