What is the result when the number 32 is decreased by 25%?

Answer:

Step-by-step explanation: [-2.19] = -3

[3.67] = 3

[-0.83] = -1

The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.

This can be generalized as given below:

[x] = -2, -2 ≤ x < -1

[x] = -1, -1 ≤ x < 0

[x] = 0, 0 ≤ x < 1

[x] = 1, 1 ≤ x < 2

Answer:

y = - [tex]\frac{3}{2}[/tex] x

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (0, 0) ← 2 points on the line

m = [tex]\frac{0-3}{0-(-2)}[/tex] = [tex]\frac{-3}{0+2}[/tex] = - [tex]\frac{3}{2}[/tex] , then

y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (0, 0 )

0 = - [tex]\frac{3}{2}[/tex] (0) + c = 0 + c , so

c = 0

y = - [tex]\frac{3}{2}[/tex] x + 0 , that is

y = - [tex]\frac{3}{2}[/tex] x

  sum = (m+n)(n-m +1)/2

Step-by-step explanation:

You want an expression for the sum of the numbers from m to n.

As the example shows, the sums of the numbers written forward and backward will be the sum of the numbers at the ends of the range:

  m +n

The number of times this sum is repeated is equal to the number of numbers in the range:

  n -m +1

The sum of the numbers in the range will be half the product of these values:

  sum = (m+n)(n-m +1)/2

[tex]-\sqrt{9y^2} = -1\cdot \sqrt{9}\cdot \sqrt{y^2}[/tex]

I assume you're good with [tex]\sqrt{9}=3[/tex], so this gives us:

          [tex]= -3\cdot \sqrt{y^2}[/tex]

Now the trick on the variable portion is that since y<0, when you square y, you turn it from being a negative number into a positive [tex]y^2[/tex] value.  And when you take the square root of that, you keep the positive value.  So effectively, [tex]\sqrt{y^2} = |y|[/tex], since it just makes the negative number become positive.

Inequality to show the shaded region in the graph:

x + 3y > -15

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given equation of the line

x + 3y = -15

Shaded region is above the line

Which can be expressed as inequality

x + 3y > -15

Answer:

Step-by-step explanation: The above answer is only partially right.  Due to the fact that the line with the arrows is solid, the sign is greater than or equal to.

So, the side with (0,0) is the side where x+3y>−15 and the shaded region (which contains (0,0)) shows the solutions of the inequality x+3y>−15.

Notice that since the boundary line is graphed with a solid line, the inequality includes the equal sign.

The graph shows the inequality x+3y≥−15.

Probability has values between 0 and 1.

What is the Probability?

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

0 represents an impossible event and 1 represents a certain event.

A probability of 0 means that an event will not occur, and a probability of 1 means that an event will certainly occur.

Probabilities between 0 and 1 represent the likelihood of an event occurring, with values closer to 1 indicating a higher likelihood of the event occurring and values closer to 0 indicating a lower likelihood.

Hence, Probability has values between 0 and 1.

The inverse Laplace transform of (2/(s+5)) is f(t) = 2 * e^(-5t)u(t).

To find the inverse Laplace transform of F(s) = (2/(s+5)), we can use partial fraction expansion and then use a table of Laplace transforms to identify the inverse transforms.

Step 1: Perform partial fraction expansion on the fraction:

(2/(s+5)) = (2/5) * (1/(1+(s/5))) = (2/5) * (1/1 + (s/5))

Step 2: Recognize the form of the partial fraction as a geometric series, and use the formula for the sum of a geometric series to find the inverse Laplace transform:

The sum of this geometric series is

(2/5) * (1/(1-(-s/5)))

= (2/5) * (1/(1+s/5))

= (2/5) * (5/5+s)

= (2/(5+s))

Step 3: Use the table of Laplace transforms to find the inverse transform of (2/(5+s)):

f(t) = 2 * e^(-5t)u(t)

where u(t) is the unit step function.

Answer:

To calculate the value of X, we first need to calculate the total amount of money Miss Saver will have saved by the time she retires at age 60.

We know that her first payment is $1000, and that every subsequent payment increases by 5%. Using this information, we can calculate the total payments made during the 30 years:

$1000 x (1 + 0.05)^30 = $1000 x 3.3201 = $3320.1

This is the total amount of money Miss Saver will have saved by the time she retires at age 60.

Next, we need to calculate the value of each annual withdrawal over the 20 years of withdrawals.

We know that the effective annual interest rate is 2% perpetually, so we can use the formula for the future value of an annuity:

FV = X * ((1 + r)^n - 1) / r

where X is the annual withdrawal, r is the interest rate (0.02), and n is the number of years (20).

We can use this formula to solve for X:

3320.1 = X * ((1 + 0.02)^20 - 1) / 0.02

X = 3320.1 * 0.02 / (1.02^20 - 1)

X = 3320.1 * 0.02 / 0.1135 = $292.36

Therefore, Miss Saver needs to withdraw $292.36 each year for 20 years to deplete her savings account.

Rounded to the nearest integer, the value of X is $292.

The equation g(x) = (x - 4) (x + 2) is in the factored form.

The x-intercepts are x = -2 and x = 4.

The axis of symmetry is x = 1.

Vertex is (1, -9).

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 8 is an equation.

We have,

g(x) = (x - 4) (x + 2)

This is in the factored form.

Now,

From the graph,

The x-intercepts are x = -2 and x = 4.

The axis of symmetry.

x = -b/2a

x = 2/2

x = 1

i.e

g(x) = (x - 4) (x + 2)

g(x) = x² + 2x - 4x - 8

g(x) = x² - 2x - 8

a = 1, b = -2, and c = -8

Now,

g(x) = x² - 2x - 8

g(x) = x² - 2x + 1 - 1 - 8

g(x) = (x² - 2x + 1) - 9

g(x) = (x - 1)² - 9

This is in the form of f(x) = a(x - h)² + k

So,

Vertex = (h, k) = (1, -9)

If you read the decimal version of 4.8 out loud, it should be "four and eight-tenths."  This will always give you a good place to start when changing a decimal into an equivalent fraction.

Now, this is a mixed number: 4 and 8/10. To further simplify it as a mixed number, we can leave the 4 alone and reduce the fraction (8/10).  Both the numerator and denominator are divisible by 2, so we can conclude (8/10) = (4/5).  A correct answer in mixed number form is 4 and (4/5).

However, to change 4 and (4/5) to a single (improper) fraction, you first multiply the denominator (5) by the large number out front on the left (4) and ADD this product to the numerator (4).  This number is your new numerator and it will still have the same denominator as before.

Here, 4 and (4/5) = [(5)*(4) + 4]/5 = (20+4)/5 = 24/5.

24 and 5 have no common factors, so this fraction is already in reduced form.

The volume of a rectangular prism is expressed as;

Given that;

First, plug in the given values into the above formula and solve for x.

V = w × h × l

117 = ( 2x - 7 )( 2x + 3 )( x - 2 )

Expand using FOIL method

( 2x - 7 )( 2x + 3 )( x - 2 ) = 117

( 2x(2x) + 2x(3) - 7(2x) - 7(3) )( x - 2) = 117

( 4x² - 8x - 21 )( x - 2 ) = 117

Expand

4x³ - 16x² - 5x + 42 = 117

4x³ - 16x² - 5x + 42 - 117 = 0

4x³ - 16x² - 5x - 75 = 0

Using rational roots text

(x - 5)(4x² + 4x + 15 ) = 0

( x - 5 ) = 0

x - 5 = 0

x = 5

4x² + 4x + 15 = 0

x = -1±i√14 / 2

Since dimensions are real and positive numbers, we use;

x = 5

To determine the dimensions of the passenger section of the train, plug in x = 5 and simplify.

Width = 2x - 7 = 2( 5 ) - 7 = 10 - 7 = 3 meters

Length = 2x + 3 = 2( 5 ) + 3 = 10 + 3 = 13 meters
