No: g(x) of not the inverse function of f(x)

Given data

f(x) = -4 ( -2x + 9 )^3 - 8

g(x) = - cube root ( -5x + 6 ) + 2

f(x) = -4 ( -2x + 9 )^3 - 8

dividing through by - 4 gives

= ( -4 ( -2x + 9 )^3 ) / -4 - ( 8  / -4)

= ( -2x + 9 )^3 -  ( -2 )

=  ( -2x + 9 )^3 + 2

finding the cube root

= ( -2x + 9 )^3 + 2

= cube root ( ( -2x + 9 )^3 + 2 )

= ( -2x + 9 ) +  cube root ( 2 )

( -2x + 9 ) +  cube root ( 2 ) ≠ g(x) = - cube root ( -5x + 6 ) + 2

The equation solved is not equal to g (x), therefore we can say that g(x) of not the inverse function of f(x)

Answer: no

Step-by-step explanation: because it says 1 mile for every 6 minutes not it takes Akiko 1 mile in 6 minutes to get to school

Given conditions:

6th term (T6) = -2

first term (a) = 18

n = 6, r = ?

Formula for finding the nth term of a GP:

[tex]tn = a {r}^{n - 1} [/tex]

Where:

T = the given value for the number of term(s)

n = the given number of term

a = The first term

r = The common ratio

Replacing for the values:

[tex] - 2 = 18 {r}^{6 - 1} \\ - 2 = 18 {r}^{5} [/tex]

Dividing both sides by 18, we have:

[tex] {r}^{5} = \frac{ - 2}{18} [/tex]

Now, we have to fifth root both sides to find the value of r.

[tex] \sqrt[5]{ {r}^{5} } = \sqrt[5]{ \frac{ - 2}{18} } [/tex]

Therefore:

Common ratio, [tex]r = -0.0638165752[/tex] [tex]≈ -0.064[/tex] to 3 decimal places.

[tex]\textsf{where $(x_1,y_1)$ and $(x_2,y_2)$ are two points on the line.}[/tex]

Define the points:

[tex]\textsf{Let}\:(x_1,y_1)=(5,7)[/tex]

[tex]\textsf{Let}\:(x_2,y_2)=(-3,-4)[/tex]

Substitute the defined points into the formula:

The population of the Bownville city reach 1,548,800 at nearly 2015

Given, Since January 2000,

The population of the city of Brownville has grown according to the mathematical model.

Y= 720,500(1.022) x

Where, X= number of years

To find:  If this continues, predict the year during which population of Brownville will reach 1,548,800

Starting population = 720,500

Growth rate = 1.022

(720500) (1.022) x = 1,548,800

1.022x = 2.1496

Taking log on both sides

log1.022x = log2.1496

x log 1.022 = log 2.1496

x=log 1.022×2.1496

x=15

Therefore, nearly it takes 15 years to reach the population 1,548,800

Hence the population of the Bownville city reach 1,548,800 at nearly 2015.

The answer would be 4/21 if divided 2/7 by 1.5 which is the correct option (C).

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have to determine the divide 2/7 by 1.5

⇒ 2/7 ÷ 1.5

Here 1.5 = 3/2

⇒ 2/7 ÷ 3/2

Apply the division operation between both term

⇒ (2/7)/(3/2)

Reciprocal the terms, we get

⇒ (2/7)×(2/3)

⇒ (2×2)/(7×3)

⇒ 4/21

Answer:

A) x = m - n - p

Step-by-step explanation:

m - x = n + p

subtract m from both sides

m - x (- m) = n + p (- m)

m cancels out on the left and stays on the right

- x = n + p - m

divide by -1 because this is the constant in front of x

visualize as -1*x if it helps (anything multiplied by 1 is that number)

(- x / -1) = (n / -1) + (p/ -1) - (m/ -1)

the positives become negative and the negatives become positive

x = -n - p + m or x = m - n - p

Step-by-step explanation:

The linear function is V(x) = 800x + 2400.

Given,

The cost of computer when purchased (the initial book value), V = 2400 (x = 0)

Company chooses to depreciate for 3 years using straight line method.

The book value after 3 years = 0 (x = 3)

We have to write a linear function that expresses the book value of the computer as a function of its age V(x).

Here, the value is depreciating over 3 years.

That is 2400 in 3 years = 2400/3 = 800

That is depreciating $800 in a year.

Now we can write the equation as:

V(x) = 800x + 2400

When we consider slope-intercept form, we can check that the above given equation of a line passes through two points: (0, 2400) and (3, 0)

Explanation:

The preimage (-6,-2) shifts to the image point (-4,-4)

Focus on the x coordinates. The jump from -6 to -4 is an increase of 2. So we have x become x+2

Now focus on the y coordinates. The jump from -2 to -4 is -2, so y becomes y-2

The translation rule we use is [tex](\text{x},\text{y})\to (\text{x}+2,\text{y}-2)[/tex] which shifts the point 2 units to the right and 2 units down.

Answer:

b, c, a

Step-by-step explanation:

The function g(x) that represents the required transformations of f(x) = x³ are;

A reflection across the x–axis;

A vertical stretch by a factor of 4;

A reflection across the y–axis;

A horizontal compression by a factor of 1/5;

The function g(x) that represents the reflection of f(x) across the x–axis is presented as follows;

g(x) = -f(x)

Therefore, we have;

f(x) = x³

Which gives;

The function, g(x) that represents a vertical stretch of a function f(x) by a factor of c, is presented as follows;

g(x) = c•f(x)

Where c = 4, we have;

g(x) = 4•f(x)

Therefore;

The function g(x) that represents a reflection across the y–axis is presented as follows;

g(x) = f(-x)

Therefore;

The function, g(x), that represents the horizontal compression of f(x) by a factor of c is presented as follows;

g(x) = f((1/c)•x)

Which gives;

g(x) = ((1/5)•x)³ = (x/5)³

The picture indicates the case of the launch of an object from the top of a building. The height of the object (f(x)), in feet, as a function of time, (x), in seconds. Both height and time are represented by non-negative real numbers and hence the following solutions do not make sense in the context of problem:

Now we proceed to fill the blanks in the four paragraphs:

f(- 2) = 0, meaning that - 2 second after the object was launched, the object was 0 feet above the ground. This interpretation does NOT make sense in the context of the problem.

f(0.5) = 100, meaning that 0.5 seconds after the object was launched, the object was 100 feet above the ground. This interpretation make sense in the context of the problem.

f(6) = - 224, meaning that 6 seconds after the object was launched, the object was - 224 feet above the ground. This interpretation does NOT make sense in the context of the problem.
