Subst. the given x and y values:  6(-1)^4 * (3)^3
                                                         6      * 27 = 162

Note that you MUST do the exponentiation first.

Also note that your post would be much clearer if you'd please use " ^ " to denote exponentiation:      6x^4 * y^3

Answer:

60 degrees

Step-by-step explanation:

C = 2(pi)r

The radius is 12 cm. We can find the circumference of a circle with radius 12 cm.

C = 2(pi)r = 2(3.14)(12 cm) = 75.36 cm

The length of the arc of the sector is 12.56 cm.

We can find the fraction this length is of the full circumference.

(12.56 cm)/(75.36 cm) = 1/6

The length of the arc of this sector is 1/6 the length of the circumference of the entire circle.

That means the angle of the sector is 1/6 the angle of an entire circle.

An entire circle has a central angle of 360 degrees.

1/6 * 360 degrees = 60 degrees

Does anyone know what irrational numbers are and if so can you explain it to me???
Romashka [77]

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. <u>Instead, the numbers in the decimal would go on forever, without repeating.  Ex) .7583947262.........    It doesn't repeat and goes on forever</u>

Two numbers have a sum of 761 and a difference of 335.what are the 2 numbers ​
melisa1 [442]

Answer:

548 and 213

Step-by-step explanation:

Use a linear function:

Let x = 1st number

Let y = 2nd number

x+y=761

x-y=335

2x=1096

x=548

plug x into either equation

548+y=761

y=761-548

y=213

548-y=335

-y=-213

y=213

I think of a number, double it, and subtract two. I get nine.
solniwko [45]

Answer:

2(x) - 2 = 9 \\ 2x - 2 = 9 \\ 2x = 9 + 2 \\ 2x = 11 \\ x =  \frac{11}{2}  \\ x = 5 \frac{1}{2}
