The function f (x) = cube root of x is an example of a logarithmic function.<br> true false

xxMikexx [17]

This is a false statement.

The cube root of x also means x raised to the 1/3rd power. In order for it to be a logarithmic function, it needs to grow as a inverse to a power function. Since we still have a number raised to a power (albeit a very low power) it is not a logarithmic function.

All logarithmic functions will approach the y axis as they get lower and lower. The cube root of x will actually hit the y-axis at (0, 0)

What is the inverse function of F(x) = -3/2x - 8

GrogVix [38]

Answer:

f-1(x)=- $\frac{2}{3}$ x- $\frac{16}{3}$

Step-by-step explanation:

First, switch f(x) to the variable "y".

y=- $\frac{3}{2}$ x-8

Next, swap "x" and "y" with each other.

x=- $\frac{3}{2}$ y-8

Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...

2x=-3y-16

Now move -16 to the left side.

16+2x=-3y

To get "y" by itself, lets divide each side by -3. Our result is...

y=- $\frac{2}{3}$ x- $\frac{16}{3}$

To finish the problem off, replace y with f-1(x) and your complete answer will be...

f-1(x)=- $\frac{2}{3}$ x- $\frac{16}{3}$

Solve the system of equations given by 5x - 2y = -6 and 15x - 6y = 6

AURORKA [14]

Answer:

8x - 3y = 12 _______( 1 )

5x = 2y + 7 _______( 2 )

On further solving ( 2 ), we get

5x - 2y = 7 _______( 3 )

Multiply ( 1 ) by 2

16x - 6y = 24 _______( 4 )

Multiply ( 3 ) by 3

15x - 6y = 21 _________( 5 )

Subtract ( 4 ) and ( 5 )

( 16x - 6y ) - ( 15x - 6y ) = 24 - 21

16x - 6y - 15x + 6y = 3

Put this in ( 2 )

5 ( 3 ) = 2y + 7

15 = 2y + 7

2y = 15 - 7

2y = 8

y = 8 / 2

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m

ikadub [295]

Answer : The number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.

Step-by-step explanation :

As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.

Now we have to determine the number of bottles should the pharmacy technician prepare to provide the required dose.

As,

The pharmacy has stock albumin = $50mL\times \frac{25}{100}$

The pharmacy has stock albumin = 12.5 mL

So,

Number of bottles should the pharmacy technician prepare to provide the required dose = $\frac{50}{12.5}$

Number of bottles should the pharmacy technician prepare to provide the required dose = 4

Therefore, the number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.
