For the function f(x) = 5(x - 5)7, find f-¹(x).

This question is incomplete , I am answering this question in general as per my knowledge.

No, because you gave T a Boolean when T expected a student as its first argument and a course as its second parameter. This will be less formal if.

The expected,

T(‘‘user2012813",‘‘discrete math")=true

However, the function F(x) and A both yield either true or false (y). Thus, you are attempting to assess

T(F(‘‘user2012813"),A(‘‘discrete math"))=T(true, false)= NULL

Only the first formulation makes sense, but after relations are established, these kinds of structures can be used.

Null functions as both a value and a pointer in computer programming. A built-in constant called null has a value of zero. It is the same as how strings in C are terminated with the letter 0.

Null is another possible value for a pointer, and unless the CPU supports a unique bit pattern for a null pointer, it has the same value as zero.

The value of k in the point (2, k) which lies on the line is -4.

How to find the value of k?

Every point lying on the curve of the line satisfies the equation of curve. Therefore, substitute the point in the given equation of line to find the value of k.

According to the given question:

The given equation is: 2y = - 3x - 2.

This is written as: 3x + 2y + 2 = 0.

Given the point (2, k) lies on the line given.

That means it should satisfy the given equation.

So, to find the value of 'k', simply substitute the point on the line.

So, it becomes: 3(2) + 2(k) + 2 = 0

⇒ 6 + 2k + 2 = 0

⇒ 2k = - 8

Dividing by 2 throughout, we get: k = - 4

Hence, (2, -4) lies on the line.

There is not enough evidence to conclude that the population mean life span for Honolulu residents is less than 77 years.

At the null hypothesis, it is tested if there is not enough evidence that the mean life span is less than 77 years, that is:

[tex]H_0: \mu \geq 77[/tex]

At the alternative hypothesis, it is tested if there is enough evidence that the mean life span is less than 77 years, that is:

[tex]H_1: \mu < 77[/tex]

We are testing if the mean is less than a value, hence we have a left-tailed test, with 20 - 1 = 19 df and a significance level of 0.05, thus the critical value is of:

t = -1.7291.

Thus the conclusion, considering the test statistic t, is given as follows:

The equation to obtain the test statistic is presented as follows:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

In the context of this problem, the values of these parameters are given as follows:

[tex]\overline{x} = 71.4, \mu = 77, s = 20.65, n = 20[/tex]

Hence the test statistic is of:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{71.4 - 77}{\frac{20.65}{\sqrt{20}}}[/tex]

Similarly, for functions, we input different numbers and we get new numbers as the result. Domain and range are the main aspects of functions. You can use quarters and one-dollar bills to buy a soda.

The machine will not give you any flavor of the soda if pennies are input. Hence, the domain represents the inputs we can have here, that is, quarters and one-dollar bills.

Step-by-step explanation:

You want the linear factorization of h(x) = x³ -6x² +13x -10.

A graphing calculator (attachment 2) shows the one positive real root is x = 2. This means (x-2) is a factor.

When we factor that out, we have a quadratic with no real roots. The vertex of its graph at (2, 1) tells us the roots of it are 2±√-1 = 2±i.

Each root p gives rise to a linear factor (x -p), so the factorization is ...

A line's steepness can be determined by looking at its slope. Slope is determined mathematically as increase over run.

According to the slope equation, the slope of a line may be calculated by dividing the rise of the line between any two places by the run of the same line between the same two sites.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

Slope of y =f(x)

Slope (m) = ΔY / ΔX = 14 / 1 = 14

y = 14x + 22

When x=0, y = 22

When y=0, x = -1.5714285714286

Slope of y = g(x)

Slope (m) =ΔY / ΔX = 14 / 1 = 14

After solving the equations we can conclude that each ticket for an adult costs $24 whereas each ticket for a child costs $6.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, 2 equations can be formed:

Let a be adults and c be children.

3a + 4c = 96 ...(1)

2a + 3c = 68 ...(2)

Now, take equation (1):

3a + 4c = 96

3a = 96 - 4c

a = 96 - 4c/3

Now, substitute a = 96 - 4c/3 in equation (2):

2a + 3c = 68

2(96 - 4c/3) + 3c = 68

96 - 4c/3 + 3c = 68/2

96 - 4c + 3c = 34*3

-c = 102 - 96

c = $6

Now, substitute c = 6 in equation (1):

3a + 4c = 96

3a + 4(6) = 96

3a + 24 = 96
3a = 96 - 24

3a = 72

a = 72/3

a = $24

3. The profit portion they will share is $200

Let S, T, F and V represent the prize of the second, third, first and fourth  place respectively

Statement 1 can be written as:

S = 2T  --- (1)

Statement 2 can be written as:

F = S + 20  --- (2)

Statement 3 can be written as:

F + S + T = 200  --- (3)

Substitute (1) and (2) into (3):

F + S + T = 200

(S+20) + 2T + T= 200

(2T+20) +2T + T= 200          (Since S = 2T)

2T+20 +2T + T= 200

5T + 20 = 200

5T = 200-20

The value of the h is A(2) / b when the formula is A = 1/2bh the formula is area of the triangle.

Given that,

We have a formula A = 1/2bh

We have to find h value from the formula.

We know that,

The variable h should be on one side of the equation, and the rest should be on the other. Divide the two sides in half as a good place to start. In this way, we eliminate the undesirable fraction.

A / 1/2 = 1/2bh / 1/2

Now on the right hand side left the 1/2 cancels out.

A / 1/2 = bh

And when a fraction is divided, the result is the same as multiplying it backwards.

A(2/1) = bh

Now, divide both sides by b.

A(2) / b = bh/b

On the left hand side b cancels out and we are left with the final product.

h = A(2) / b

Therefore, The value of the h is A(2) / b when the formula is A = 1/2bh the formula is area of the triangle.
