Simplify by rationalizing the denominator

1 answer:

7 0

Answer: To rationalize the denominator, you must remove any radical expressions in it, such as square roots and cube roots. The key concept is to multiply the original fraction by an appropriate number so that the denominator no longer contains radicals after simplification.

Factor each polynomial <br> -28y^2-12y^5

artcher [175]

Answer:

y= $-\frac{\sqrt[3]{63} }{3}$

y=0

Step-by-step explanation:

− 4 $y^{2}$ ( 3 $y^{3}$ + 7 )

-4 $y^{2}$ =0, ( 3 $y^{3}$ + 7 )=0

$y^{2}$ =0 3 $y^{3}$ =-7

y=0 $y^{3}$ = $\frac{-7}{3}$

y= $-\frac{\sqrt[3]{63} }{3}$

Find the measure of the indicated angle to the nearest degree.

fredd [130]

Step-by-step explanation:

Let the measure of required angle be x degree

$\therefore \tan \: x = \frac{33}{56} \\ \\ \therefore \tan \: x = 0.589285714 \\ \\ \therefore \: x = {\tan}^{ - 1} (0.589285714) \\ \\ \therefore \: x = {\tan}^{ - 1} ( \tan \: 30.510237394 \degree) \\ \\ \huge \red{ \boxed{\therefore \: x = 31\degree}}$

Thus, first option is the correct answer.

Why is (3,-5) not a solution to -x+4y=-15

Olegator [25]

C) It doesn’t satisfy either the top or bottom equations.

When we plug them into the top equation:
$- 3 + 4( - 5) = - 15$
Simplify:
$- 3 + ( - 20) = - 15 \\ \\ - 23= - 15$
Because the statement of -23 = -15 is wrong, the solution pair is wrong for the top equation.

When we plug them into the bottom equation:
$- 2(3) - 3( - 5) = - 8$
Simplify:
$- 6 - ( - 15) = - 8 \\ \\ 9 = - 8$
9 = -8 is not a valid statement, so the pair doesn't satisfy both of the equations.
