What is absolute value function?

The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is denoted by the symbol |x|. Specifically, |x|=x and |x|=-x, respectively, if x is a positive number, and |0|=0 otherwise.

The vertex form of an absolute value function is f(x) = a |x - h| + k where

(h, k) is the vertex from which the graph starts and a = m is the slope.

So, the absolute value function  p(x) = |x - 9|, means h =-(-9) = 9 and

k = 0, will result in the vertex at (9, 0).

The absolute value function q(x) = |x| +9 , means h = 0 h=0 and k =9, will result in a vertex (0, 9).

The absolute value function r(x) = |x + 9|,  means, h = -9 and, k=0, will result in the vertex at (-9, 0).

The absolute value function t(x) = |x| -9 , means h = 0 and k = -9, will result in the vertex at (0, -9)

Hence,

The vertex of p(x)  is (9, 0).

Vertex of q(x) is (0, 9).

Vertex of r(x) is (-9, 0).

Vertex of t(x) is (0, -9).

The probability that the average length of a randomly selected bundle of steel rods is 0.165

Given population mean(μ)=109cm

standard deviation(σ)=1.6cm

sample size(n)=27

Let x represents the lengths of an individual rod then the z-score for

z=x-μ/σ----------(1)

Also, the z score for the sample mean, x:

z=(¯x−μ)/σx

The standard error:

σ¯x=σ/√n-------------(2)

      =1.6/√27

       =1.6/5.196

σ¯x =0.3079

For a bundle of 27rods, the probability that the average length is between 109 cm and 108.7-cm:

considering m=108.7cm

P(n-m/σx)------------(3)

[tex]P(109 < x < 108.7)=P(\frac{109-108.7}{0.3079} )\\\\ P(109 < x < 108.7)=P(z < -0.974)\\[/tex]

The quadratic equation is x² - 2x - 24

What is quadratic equation ?

Any equation in algebra that can be written in standard form as where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation. In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.

Square and quadrangle difficulties have a close relationship with quadratic equations (another name for rectangles). In actuality, the Latin word quadratus, which means square, is the root of the word quadratic.

Any quadratic problem can be solved using the quadratic formula. The equation is first changed to have the form ax2+bx+c=0, where a, b, and c are coefficients. After that, we enter these coefficients into the following formula: (-b(b2-4ac))/(2a).

Given roots of quadratic equation are 6 and -4.

Also given here leading coefficient is 1.

We know that, the formulae for forming quadratic equation when its roots are given is as follows: x² - (α+β)x + αβ

Here α and β are the roots of the quadratic equation.

Let  α = 6 and β = -4

Putting the value of  in the above formulae we get,

x² - (6-4)x - 24

x² - 2x - 24

But remember here 1 is the leading coefficient of the quadratic equation with roots 6 and -4 (given in question),so we have to multiply the equation by 1 to get the final answer.

The equation of the polynomial P3 is  p3​(t) = 5/6t³− 17/6t​

Equation:

In algebra, an equation consists of variable, number and constants.

Given,

Here we need to find the polynomial P3 such that {P0, P1, P2, P3} is an orthogonal basis for the subspace P3 of P4.

And the scale the polynomial p3 so that its vector of values is (-1,2,0, -2,1).

Here we know that the polynomial (before the scaling) p3​ is just the difference between t³ and its orthogonal projection on the span of 1,t,t²−2.

Then we showed that the projection is ​, hence

p3​(t) = t³− 17/5t​

When here we have the  scale this polynomial such that the vector of values at t=−2,−1,0,1,2 is (−1,2,0,−2,1).

Now, we need to find the scalar α, it can be written as,

=> α⋅p3​(−2)=−1

=> α⋅p3​(−1)=2

=> α⋅p3​(0)=0

=> α⋅p3​(1)=−2

=> α⋅p3​(2)=1

Here from the 4-th equation we have the value of

=> α⋅(1- 17/5) = -2

=> α = 5/6​

And it is easy to check that all the equations are satisfied with this α.

Therefore, the required polynomial p3 is

Answer: The rates are not equivalent.

Step-by-step explanation: You have to find the unit rate. This means the number of laps per minute. To find this out you have to divide 12 by 4 which equals 3 and divide 18 by 8 which equals 2.25. Now we know the rates are not equivalent because your rate is 3 laps/minute and your friend's rate is 2.25 laps/minute.

Answer: The rates are not equivalent

Step-by-step explanation:

Firstly,You must identitify the ratio.
The ratio can be 12:4 and 18:8.

Now we must convert 4 minutes and minutes into seconds to make it easier for us to work with.
4 * 60 = 240

18 * 60 = 1080

Now the question is 12: 240 equavialent to 18: 1080.

Method A:

For 12:240 to get 1 lap :

we can divided 240/12 = 20.

1 lap takes 1/3 of a minute or 20seconds.

For 18:1080:

We divide 1080/18 = 60= 1 minute

12:240=20 seconds

18:1080= 60 seconds.

They are not equivalent.

Method B:Compare 12:240 to 18:1080 and divide by 2

if the ratio  split 50/50,they are equavalent.

Add the seconds together,becuase that is the total time

1080+240= 1320 second.

12+ 18=20

Now the ratio is 30:1320

1 lap takes 1320 / 30 = 44seconds

12 laps * 44 = 528s

18laps * 44 = 792s

528s is not 792s.

Step-by-step explanation:

The theoretical probability of rolling an odd number on a die is 1/2, or 0.5. Since Tami rolled the die 20 times and it landed on an odd number 6 times, the experimental probability of rolling an odd number is 6/20, or 0.3. Since 0.3 is less than 0.5, the theoretical probability is higher. Therefore, the correct answer is option A: "The theoretical probability is higher."

Answer:

Domain: [tex](-\infty, \infty)[/tex]

Range: [tex]f(x)\ge 0[/tex]

Step-by-step explanation:

Interval Notation is one way to express a range of values. This is usually denoted with two values, let's just say "a" and "b" as: [tex](a, b)[/tex] where "a" is less than "b", so the lower value goes on the left the higher values goes on the right.

The next thing to note is the difference between square brackets and parenthesis. Whenever you use a square bracket next to a value in interval notation, that means the value is included. If you use a parenthesis, that means the value is not included.

So for example: [tex](2, 4][/tex] means all values between 2 (excluding 2) and 4 (including 4)

The domain of a function, or a relation, can be defined as all x-values that are on the graph. In most cases this is all real numbers which can also be denoted as: [tex](-\infty, \infty)[/tex] which is saying all values between negative infinity and positive infinity.. which is any real number. The only time the domain doesn't include x-values, is because the line isn't defined at that x-value OR based on the context, only certain values are in the domain e.g (time after an event; only positive numbers)

In the function provided: [tex]f(x)=|x+6|[/tex] there is no x-value in which this function is undefined. So the range is all real numbers or [tex](-\infty, \infty)[/tex]

The range of a function, or a relation, similar to the domain,  can be defined as all y-values that are on the graph.

Now to determine the range of the function, we first need to understand what the absolute value is doing to the (x+6) inside of it.

The absolute value of any real number can be defined as the distance from zero. When applied to any positive number, the value stays the same (since thd distance from zero IS that number). When applied to any negative number, the value becomes the positive value of that number since distance is positive. For example -6 has a distance of 6 units to the left of zero, but distance is a scalar it doesn't care about the direction, it's just 6 units away from zero, which is why it becomes positive when taking the absolute value.  When applied to zero... it just stays zero, since 0 is 0 units away from zero...

So the minimum value of |x+6| is going to be zero, which occurs when x+6 is equal to zero. If it's a negative number or positive number inside it's always going ot output a positive number. And for positive numbers it actually remains positive, so once it reaches the turning point (where it goes from increasing to decreasing) it's going to keep increasing to positive infinity.

This means the range is all values greater than or equal to zero, which can be denoted as: [tex][0, \infty)[/tex] OR [tex]f(x)\ge 0[/tex] since the f(x) represents the "y" value, all the inequality is saying, is that the y-value will always be greater than or equal to zero.

(a) As time goes on and approaches infinity, the level of oxygen in the pond approaches normal, therefore;

The oxygen level will eventually approach its  normal level in the long-run

(b)  The number of weeks after which the oxygen level becomes 60% of its normal level are 0.5, 2 weeks

The rational polynomial function  in which the numerator and denominator have the same power and the coefficient of the highest power are the same indicates that the value of f(t) approaches 1 (normal) as t approaches infinity.

The function with which the oxygen level in the pond can be found is presented as follows;

[tex]f(t) = \dfrac{t^2-t + 1}{t^2+ 1}[/tex]

f(0) = 1, therefore

The end behavior of the function as the value ot t approaches infinity is therefore the asymptote;

y = 1/1 = 1

The  value of the function f(t) as the value of t approaches infinity is that the f(t) approaches 1, which is the normal level of oxygen in the pond

(b) When the oxygen level is 60%, we get;

[tex]f(t) = \dfrac{t^2-t + 1}{t^2+ 1} = 60\% = 0.6[/tex]

0.6·(t² + 1) = t² - t + 1

0.6·t² + 0.6 = t² - t + 1

0.4·t² - t + 0.4 = 0

t² - 2.5·t + 1 = 0

Therefore;

(t - 2)·(t - 0.5) = 0

t = 2 or t = 0.5

a. The population of the state in 2000 is 18.5 million

b. The population will reach 26.6 million in about 2 years

From the question, we are to determine the population of the state in 2000.

From the given information,

The formula that models the population of the US state after 2000 is

A = 18.5e^(0.1708t)

To determine the population of the state in 2000, we will substitute t = 0

That is,

A = 18.5e^(0.1708(0))

A = 18.5e^(0)

A = 18.5(1)

A = 18.5

Thus, the population of the state in 2000 is 18.5 million

b. To determine when the population will reach 26.6 million

Substitute A = 26.6 in the equation

A = 18.5e^(0.1708t)

26.6 = 18.5e^(0.1708t)

Solve for t

26.6/18.5 = e^(0.1708t)

ln(26.6/18.5) = 0.1708t

0.36314048 = 0.1708t

t = 0.36314048/0.1708

t = 2.126

t ≈ 2
