81 is 3^4, so

$3^4 \cdot x^4 \cdot \left(y^2\right)^4 = \left(3 \cdot x \cdot y^2\right)^4 = \boxed{\left(3xy^2\right)^4}$

If sin(theta) =4/5 and is in quadrant 2, the value of cot(theta

iren [92.7K]

$\sin\theta= \frac{4}{5} 
\\
\\\sin^2\theta+\cos^2\theta=1
\\ \cos\theta=\pm \sqrt{1-\sin^2\theta} =\pm \sqrt{1-( \frac{4}{5})^2 } =\pm \sqrt{1- \frac{16}{25} } =\pm \sqrt{\frac{9}{25} }=\pm \frac{3}{5}}$

$\theta \in II \Rightarrow \cos\theta\ \textless \ 0 \Rightarrow \cos\theta=-\frac{3}{5}$

$\cot\theta= \frac{\cos\theta}{\sin\theta}= \frac{-\frac{3}{5}}{\frac{4}{5}} =- \frac{3}{4}$

An ostrich egg weighs 64 ounces is the weight of the ostrich egg greater than 5 pounds?

IgorLugansk [536]

Answer:

An ostrich egg is 4 pounds, therefore, an ostrich egg is not greater than 5 pounds.

Step-by-step explanation:

Convert the ounces to pound.

1 pound = 16 ounces

Next, divide.

64 ÷ 16 = 4.

4 < 5

So, an ostrich isn't greater than 5 pounds

Have a wonderful day!

Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15

Norma-Jean [14]

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x
