Mathematics

By definition of cubic roots and power properties, we conclude that the domain of the cubic root function is the set of all real numbers.

<h3>What is the domain of the function?</h3>

The domain of the function is the set of all values of x such that the function exists.

In this problem we find a cubic root function, whose domain comprise the set of all real numbers based on the properties of power with negative bases, which shows that a power up to an odd exponent always brings out a negative result.

<h3>Remark</h3>

The statement is poorly formatted. Correct form is shown below:

<em>¿What is the domain of the function </em>y = \sqrt[3]{x - 1}<em>?</em>

What is (4x + 3) + (-2x + 4)
kobusy [5.1K]

Answer:

(4x + 3) + (-2x + 4) = 2x + 7  

Step-by-step explanation:

(4x + 3) + (-2x + 4) =     you then collect like terms  

(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis

= 2x + (3 + 4). step-by-step

= 2x + 7.  then that is how you get =2x+7

If (5-3i)(x+iy)/(4-5i) = (2+i)^2-(3-4i)^2, then x=___ and y=____
Leona [35]
This looks complicated

lets simplify both sides

By multiplying top and bottom by the conjugate:-

left side  =  (5-3i)(x + iy) (4+5i)          (5-3i)(x + iy) (4+5i) 
                  ------------------------   =      ------------------------
                        (4-5i)(4+5i)                           41

right side =  (2 + i + 3-4)(2+i - 3 + 4i)    (by  Difference of 2 squares)

               =  5-3i)(-1 + 4i)

so as left side = right side

(5-3i)(x+yi)(4+5i)   = 41 (5-3i)(-1+5i)

5-3i is common so:-

(x + iy)(4+5i) = 41(-1+5i)

4x +5xi + 4yi - 5y = -41 + 205i

4x - 5y + (5x + 4y)i = -41 + 205i

EQuating coefficients we are left with the system of equations

4x -  5y = -41
5x + 4y  = 205

solving this gives x = 21 and y = 25

13.5-ounce bottle cost 2.19. A 29.2-ounce bottle costs 5.37 find the unit price for each size
maks197457 [2]

Answer:

A)Unit prize is $0.162

B)Unit prize is $0.183

Step-by-step explanation:

A) 13.5-ounce bottle cost 2.19

Cost of 13.5 ounce bottle =2.19

Cost of 1 ounce bottle =\frac{2.19}{13.5}=0.162

So, Unit prize is $0.162

B)29.2-ounce bottle costs 5.37

Cost of 29.2 ounce bottle = 5.37

Cost of 1 ounce bottle =\frac{5.37}{29.2}=0.183

So, Unit prize is $0.183
