Answer:

x>=-11/4

Step-by-step explanation:

f(x)=[tex]\sqrt{4x+9+2}[/tex]

The number which has a square root has to be greater than or equal to 0.

Hence, 4x+9+2>=0

Solve the inequality:

4x+9+2>=0

4x+11>=0

4x>=-11  ==> subtract 11 on both sides to isolate x

x>=-11/4 ==> divide both sides by 4

The distance traveled by the arrow cannot be determined from the given information. The distance traveled by the arrow depends on the speed at which it is fired, which is determined by the amount of energy released when the bowstring is released.

The sum of two or more numbers that results in a third number is called a factor.

The factor of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex] exists 2x + 1.

The definition of a factor is a number that divides another number by itself with no remainder. In other words, if multiplying two whole numbers results in a product, the numbers we are multiplying are factors of the product since the product is divisible by them.

What can split a number exactly are factors. So there is no residual after division. Factors are the sums of two or more numbers that produce a third number. Consequently, a factor is a number that divides another.

The use of more variable factors—those whose values do fluctuate with output—occurs as production rises and falls. Workforce, energy, and directly used raw materials are examples of typical variable components.

Let the given equation be [tex]$& x^2+\frac{x}{6}-\frac{1}{6} \\[/tex]

[tex]$& =\frac{6 x^2+x-1}{6} \\[/tex]

simplifying the above equation, we get

[tex]$& =\frac{1}{6}\left(6 x^2+x-1\right)[/tex]

We will factorize the polynomial by splitting its middle term.

[tex]$& \frac{1}{6}\left(6 x^2+x-1\right) \\[/tex]

[tex]$& =\frac{1}{6}\left(6 x^2+3 x-2 x-1\right) \\[/tex]

simplifying the above equation, we get

[tex]$& =\frac{1}{6}(3 x(2 x+1)-1(2 x+1)) \\[/tex]

[tex]$& =\frac{1}{6}(3 x-1)(2 x+1)[/tex]

[tex]$\frac{1}{6^{}}(3 x-1)$[/tex] and (2x + 1) are factors of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex]

Therefore, the correct answer is option B. 2x + 1

The complete question is:

Which among the following is a factor of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex] ?

A. 3x + 1

B. 2x + 1

C. [tex]$x-\frac{1}{5}$[/tex]

Arya needs to add 2 gallon of 70% antifreeze must be added to a  3-gallon mixture containing 20% antifreeze to obtain the mixture they need.

What is antifreeze?

Antifreeze is an additive that lowers a liquid's freezing point that is made of water. For cold environments, freezing-point depression is accomplished using an antifreeze mixture. Additionally, common antifreezes raise the liquid's boiling point, enabling higher coolant temperatures.

Let x be the amount of 70% antifreeze to be added, in gallons.

In terms of percentage of antifreeze, we write:

20% of 3 gallons + 70% of x gallons = 50% of (3 + x) gallons

0.2(3) + 0.7x = 0.5(3 + x)

0.6 + 0.7x = 1.5 + 0.5x

0.7x - 0.5x = 1.5 - 0.6

0.2x = 0.4

x = 2

Step-by-step explanation:

In a case of binomial distribution of of x where n = 5 and p = 0.05, the probability that x is at least 1 is not 0.6240, it is 0.2262.

Therefore, the answer is False.

The formula for binomial distribution is

P = nCx × pˣ × (1 - p)⁽ⁿ⁻ˣ⁾

where P is the probability

n is the total number of trials

x is the number of success trial

p is the probability of success in a single trial

From given details

n = 5

p = 0.05

P( x is at least 1) = 1 - P( x is less than 1)

P( x is at least 1) = 1 - P( x is 0)

P( x is at least 1) = 1 - 5C0 × 0.05⁰ × (1 - 0.05)⁽⁵⁻⁰⁾

P( x is at least 1) = 1 - 1 × 1 × 0.95⁵

The required graph of the given function y = -5x + 3 which has been attached below.

A graph can be described as a visual representation or a diagram that represents data or values.

To graph the function y = -5x + 3, you can start by making a table of values.

Here's an example:

x y

-2 -11

-1 -6

0 3

1 -2

2 -7

To plot these points, start by graphing the point (0,3). This is the y-intercept, where the line crosses the y-axis.

Then, use the slope of the line (-5) to find the next point. For example, if you go one unit to the right on the x-axis (from 0 to 1), the y-value decreases by 5 (from 3 to -2).

Continue graphing points in this way until you have plotted enough points to see the shape of the line. You should see that the line has a negative slope, meaning it goes down from left to right.

Answer:

The boats cross paths at the points (1,8) and (4,11)

Step-by-step explanation:

First, we want to find the points of intersection between the two paths. We are given two equations, both in the form y=(equation). Since we want to find the intersection points, we set the two equations equal to each other (since both equal y we can plug one of the equations in for y into the other equation) to get

-x^2+6x+3=x+7

From here, we solve this like a normal quadratic equation, move all variables to one side first

-x^2+5x-4=0

This factors to -(x-1)(x-4)=0, giving us x=1 and x=4

Now we plug these back into one of the original equations (in this case the linear equation is much more simple) to give us the points (1,8) and (4,11)

There is always at least one consecutive value of n for which Marvin has a successful approach.

By induction, we can demonstrate that the game must conclude after a maximum of n(n+1)/2 turns for the first half of the issue, Here Induction Means a method for demonstrating that a statement P(n) is true for every natural number n, and that the infinitely numerous examples P(0), P(1), P(2), P(3), etc. all hold, is mathematical induction. Informal analogies, such a ladder or a falling domino, are used to explain this technique .

Base case: If there is just one bowl, Marvin can get rid of it in one turn, ending the game after one.

Step one of induction: Assume that there are k bowls and that the game terminates after no more than k(k+1)/2 turns. When there are k+1 bowls, we shall demonstrate that the game terminates after at most (k+1)(k+2)/2 turns. The number of bowls lowers by one if Marvin takes a marble out of one, and the game must terminate after no more than k(k+1)/2 turns through induction hypothesis

When Marvin transfers a marble from bowl A to bowl B, where bowl A contains at least one marble and bowl B contains an equal number of marbles, bowl A loses one marble and bowl B gains one marble. The number of bowls stays the same because bowl B has at least as many marbles as bowl A. As a result, the game must still terminate after k(k+1)/2 turns at the latest.

In any scenario, the game ends after at most k(k+1)/2 turns, thus when there are k+1 bowls, the game must end after at most (k+1)(k+2)/2 turns. For the second component of the issue, we can demonstrate that for every positive integer k, there exists a n such that Marvin can devise a plan to extend the n-bowl game for at least kn turns.

Let's say Marvin wants the n-bowl match to go at least kn turns. He can accomplish this by ensuring that each bowl always contains at least k marbles. Marvin can start by putting k marbles in the first bowl, k-1 marbles in the second bowl, and so forth, down to 1 marble in the nth bowl, to accomplish this.

For the second component of the issue, we can demonstrate that for every positive integer k, there exists a n such that Marvin can devise a plan to extend the n-bowl game for at least kn turns.

Let's say Marvin wants the n-bowl match to go at least kn turns. He can accomplish this by ensuring that each bowl always contains at least k marbles. Marvin can start by putting k marbles in the first bowl, k-1 marbles in the second bowl, and so forth, down to 1 marble in the nth bowl, to accomplish this.

Marvin can select a bowl containing at least k marbles on each turn and transfer one marble to a bowl containing fewer than k marbles .Marvin can transfer one marble from the first bowl to the second bowl, for instance, if there are k+1 marbles in the first bowl and k marbles in the second bowl. This guarantees that there are at least k marbles in each bowl. The game will go for at least kn turns because Marvin can take at least one turn every bowl.

For the third component of the issue, we can demonstrate that there is always at least one value of n for which Marvin has a successful strategy.

Assume that n is a positive integer. We shall demonstrate that either Marvin or Marisa has a winning strategy for the game of n bowls or the game of (n+1) bowls.

If Marvin has a winning strategy for the N-bowl game, he can use that method to win the N-bowl game.

If Marisa has a winning strategy for the n-bowl game and Marvin does not, then Marisa does as well. In this scenario, Marvin can use Marisa's successful approach to the n-bowl game as his own successful approach to the (n+1)-bowl game.

The larger the base of a log function, the closer the graph approaches the asymptote of x = 0.

We know that for a exponential function b^x = y, b is the base, y is the exponent to which the base b is raised and x is the result obtained.

We can write this in logarithmic form as:

log_b(x) = y

A logarithm base is the subscript of the logarithm that carries or raises the exponent.

For example in case of log_(3) 9 = 2, the base here is 3.

The change of base formula is:

log_b(x) = log_c(x) / log_c(b)

Also as we know the bigger the logarithm base, the smaller the curve on the graph. This means, the larger the base of a log function, the closer the graph approaches the asymptote of x = 0.

The log function may increase at a slower rate if the base increases.

Therefore, if the base of a log function is large, the graph approaches the asymptote of x = 0.
