Answer:

4x^5\sqrt[3]{3x}

Step-by-step explanation:

\sqrt[3]{16x^7}  \times \sqrt[3]{12x^9}\\\\(2^4 x^7)^{\frac{1}{3}}  \times (2^2 \times 3 x^9)^{\frac{1}{3}}\\\\2^{\frac{4}{3}}  \times x^{\frac{7}{3}}  \times 2^{\frac{2}{3}} \times 3^{\frac{1}{3}} \times x^{\frac{9}{3}}\\\\2^{\frac{4}{3} + \frac{2}{3}} \times x^{\frac{7}{3} + 3} \times 3^{\frac{1}{3}}\\\\2^{\frac{6}{3}} \times x^{\frac{16}{3}} \times\sqrt[3]{3}\\\\2^2 x^5 \sqrt[3]{x}  \times \sqrt[3]{3} \\\\4x^5 \sqrt[3]{3x}

The length of one leg of a right triangle is 20.3 centimeters. The length of the hypotenuse is
meriva
<h3>Answer:  Approximately 23.0 cm</h3>

=====================================================

Work Shown:

a = 20.3

b = unknown

c = 30.7

Apply the pythagorean theorem to find b

a^2 + b^2 = c^2

(20.3)^2 + b^2 = (30.7)^2

412.09 + b^2 = 942.49

b^2 = 942.49-412.09

b^2 = 530.4

b = sqrt(530.4)

b = 23.0304146727757  value is approximate

b = 23.0

I rounded to one decimal place because the other values (20.3 and 30.7) were to one decimal place.

What is the parallel slope intercept form pls help?​
malfutka [58]
<h2>Answer:</h2>

If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.

-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b

Now that we have the y-intercept, we can create the equation.

y = 4x - 17

We can prove this by graphing both lines, like so.
