Answer 1

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

Since we have that:

[tex]p=-0.5[/tex]

We'll have that:

[tex]\frac{1}{4p}\rightarrow\frac{1}{4(-0.5)}\rightarrow-\frac{1}{2}[/tex]

Therefore, we can conclude that the answer is:

[tex]-\frac{1}{2}[/tex]

The one-to-one function f is defined below.

Answers

The inverse function of the relation is f-1(x) = 5x/(7x -6), while the domain and the range are x < 6/7 or x > 6/7 and f(x) < 5/7 or f(x) > 5/7, respectively

How to determine the inverse function?

The definition of the function is given as

f(x) = 6x/7x - 5

Rewrite the function as

y = 6x/7x - 5

Next, we swap or switch the variables x and y

So, we have the following equation

x = 6y/7y - 5

Cross multiply in the above equation

This gives

x(7y - 5) = 6y

Open the brackets

7xy - 5x = 6y

Collect the like terms

7xy -6y = 5x

Factor out y

y(7x -6) = 5x

So, we have

y = 5x/(7x -6)

Express as inverse function

f-1(x) = 5x/(7x -6)

Using a graphing calculator, we have

Domain: x < 6/7 or x > 6/7

Range: f(x) < 5/7 or f(x) > 5/7

Answers

the answer to the first question is the third one
because the constant relationship between the x and y coordinates makes the point go through the origin and makes a straight line.

Find the area of the figure.A. 57 square yardsB. 66 square yardsC. 180 square yards D. 234 square yards

Answers

We would section the figure into two shapes as shown below

We can see a trapezium and a rectangle. We would find the area of each figure and add them.

For the trapezium,

Area = 1/2 * (a + b)h

a nd b are the opposite sides of the trapezium while h represents the height.

Thus,

a = 20, b = 24 and h = 9es of the trapezium while h represents the height.

M = $6,400

C = $3,600

CD interest = $180

Money market interest = $256

Here, we want to start by completing the chart

We proceed as follows;

Let us take it line by line

a) The rate for the CD account is 5%

Writing this as decimal is 5/100 = 0.05

b) The time for the CD account is 1 year

Next line;

a) Principal invested in money market is $M

b) The time is also 1 year

Next line;

The interest earned on investment is the sum of both

That will be;

0.05c + 0.04m

So, let us write the equations to solve simultaneously;

[tex]\begin{gathered} c\text{ + m = 10,000} \\ 0.05c\text{ + 0.04m = 436} \\ \text{second equation multiplied through by 100;} \\ 5c\text{ + 4m = 43,600} \\ \text{From i;} \\ c\text{ = 10,000-m} \\ \text{put this into the multiplied equation} \\ 5(10,000-m)\text{ + 4m = 43600} \\ 50,000\text{ - 5m + 4m = 43600} \\ m\text{ = 50,000-43600} \\ m\text{ = 6400} \\ c\text{ = 10,000-6400} \\ c\text{ = 3,600} \end{gathered}[/tex]

So, let us fill the last parts;

a) $3,600 + $6,400 = Total $10,000 invested

b) CD interest is 0.05 c = 0.05 (3,600) = $180

Money market interest = 0.04M = 0.04 (6,400) =$256

$180 + $256 = $436 total interest

The top of the hill rises 243 feet above checkpoint 2, which is -162. What is the altitude of the top of the hill?

Answers

The altitude of the top of the hill or the difference in elevation point is 406 feet.

Difference in Elevation Point

The vertical distance between two points is called the difference in elevation. The process of measuring differences in elevation is called levelling , and is a basic operation in topographical surveys.

To determine the difference in elevation between two points, determine the elevation at each point and then calculate the difference.

Point A = 243 feetPoint B = -162 feet

The difference in elevation between the two points is

Point A - Point B = 243 - (-162) = 243 + 162 = 406

The difference in the elevation point is 406 feet.

Using d for distance traveled in miles and g for

and g.

Answers

The equation can be written as d=30g

What is an equation?

An equation can be compared to a scale on which objects are weighed. When the two pans are filled with the same amount of anything (like grain), the scale will balance and the weights will be considered equal. To maintain the scale in balance, if any grain is taken out of one of the balance's pans, an equal amount must be taken out of the other pan. More broadly, if the identical operation is carried out on both sides of an equation, the equation remains in balance. Equations are used to describe geometric shapes in Cartesian geometry. The goal has changed since the equations under consideration, such as implicit equations or parametric equations, contain an unlimited number of solutions.

How much will it cost to buy a low fence to put all the way around the bed? The fencing material costs $0.59 per foot and can only be bought in whole numbers of feet.

To find the cost we first need to know how many feet of fence we need. To do this we add all the lengths of the sides:

Now, since we can only buy whole numbers of feet we need to buy 21 feets of fence, then the total cost is:

Of the twenty-two students in a classroom, ten are transfer students, seven are nursing students, four are AAS students and one student is undecided.If three students are chose randomly, without replacement, find the probability that all three students are nursing students.

Answers

Given that:

• There are a total number of 22 students in the classroom.

,

• 10 of them are transfer students.

,

• 7 are nursing students.

,

• 4 are AAS students.

,

• 1 student is undecided.

,

• Three students are chosen randomly.

Since you need to find the probability that all three students that are chosen randomly are nursing students, you need to set up that this is:

[tex]P(A)[/tex]

Where Event A is that one of the students is a nursing student.

Therefore, the probability that three of the chosen students are nursing students can be set up as:

[tex]\begin{gathered} P=P(A)\cdot P(A)\cdot P(A)=P(A)^3 \\ \\ P=P(A)^3 \end{gathered}[/tex]

Knowing that the total number of students is 22 and 7 of them are nursing students, you know that:

[tex]P(A)=\frac{7}{22}[/tex]

Therefore:

[tex]P=(\frac{7}{22})^3[/tex][tex]P=0.0322[/tex]

Hence, the answer is:

[tex]P=0.0322[/tex]

Answers

EXPLANATION

x + y = 8 ----------------------------------------(1)

5x - 3y = 24 ------------------------------------------(2)

If we are to eliminate y in the equations, we first need to multiply through equation (1) by 3.

3x + 3y = 24 ----------------------------------------(3)

Add equation (2) and equation (3).

If we add equation(1) and equation(3) together, -3y will cancel-out 3y.

(5x + 3x) = (24 + 24)

8x = 48

Therefore, the correct option is D. 8x = 48
