1. Evaluate -3x^3 -2y^2 when x=-5 and y =3

Answer:

357

Step-by-step explanation:

A) We replace x = - 5 and u = 3 into -3x^3 -2y^2

and we have -3x^3 -2y^2= -3*(-5)^3 -2*3^2= -3*(-125)- 2*9

or -3x^3 -2y^2 = 375-18= 357

The answer is 357.

B) Replace h = -2 into h^2-3h+2

we have h^2-3h+2 = (-2)^2 -3*(-2) +2 = 4 +6 + 2= 12

The answer is 12

Have a good day.

What is the price if you mark up $50 by 10%
BARSIC [14]

Answer:

55

Step-by-step explanation:

Original price = 50 and percent markup is 10%

The increase is the original price times the percent markup

increase = 50 * 10%

increase  = 50*.10

                = 5

The new price is the original price plus the increase

new price = 50 + 5

                 = 55

Fed [463]

Answer:

0.02 (rational)

2 (rational)

Square root of 2 (irrational)

Square root 1/2 (irrational)

Step-by-step explanation:

Rational numbers are numbers that can be in form of a/b such that a and b are not zeros. In other words, a and b are integers ranging from 1 to infinity.

Conversely, irrational numbers are numbers that are endless and are non repeating digits after decimal point.

Thus, from the questions above;

0.02 =   \frac{2}{100}  = rational \: number

2 =  \frac{2}{1}  = rational \: number

\sqrt{2}  = 1.41421356 = irrational \: number

\sqrt{ \frac{1}{2} }  = 0.70710678 = irrational \: number
