Answer:

5.03\frac{rad}{sec}

Step-by-step explanation:

To find the angular velocity divide the revolutions by the time

so

\frac{16}{20}=0.8\frac{rev}{sec}

Remember that

1\ rev=2\pi \ rad

Convert rev/sec to rad/sec

0.8\frac{rev}{sec}=0.8*(2\pi)=1.6 \pi\frac{rad}{sec}

assume \pi=3.1416

1.6(3.1416)=5.03\frac{rad}{sec}

Write the expression as a square of a monomial. <br><br><br><br><br><br><br><br><br><br> a 81x^4
poizon [28]

Answer:

(9x²)²

Step-by-step explanation:

Given the expression 81x⁴, to write the expression as a square of a monomial, first we will assign a variable to the expression.

y = 81x⁴

Then we take the square root of both sides of the expression

√y = √81x⁴

y^½ = √81 × √x⁴

y^½ = 9x²

Squaring both sides of the resulting equation to get y back

(y^½)² = (9x²)²

y = (9x²)²

The expression as a square of a monomial is (9x²)²
