Which of the following choices are equivalent to the expression below? check all that apply

Naddika [18.5K]

The choices are equivalent to the expression correct choices are A, C, and D.

The given expression is

x^3 /5

<h3>What is the expression?</h3>

The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.

<h3>What is the power rule?</h3>

$a^{\frac{m}{n} =\sqrt[n]{a^m}$

Therefore the above power rule implies that,

$x^{(\frac{3}{5}) }=\sqrt[5]{x^3}$

Also, we have the power rule

$(a^m)}^n=a^{mn}$

$x^{\frac{3}5} =(x^3)^{\frac{1}{5}$

or it can be written as

$x^{\frac{3}{5} =(\sqrt[5]{x})^3$

The correct choices are A, C, D.

What is 0.4(0.3x-1)=2+0.75x ?

Andrews [41]

1st disribute .4 through the parentheses.

.4 (.3x-1)=2+.75x
.12x-.4=2+.75x

subtract .12x from each side

-.4 = 2 + .63x

subtract 2 from each side

-2.4 = .63x

Divide each side by .63

-3.81 = x

Consider a triangle with angles 30o-60o-90o, with hypotenuse of length 2. Calculate the lengths of the other 2 sides and store t

kumpel [21]

Answer:

1.00 and 1.73

Step-by-step explanation:

1) Calculating the 1st and the 2nd leg using trigonometric function sine:

$sin (30^{0})=\frac{c}{2}\Rightarrow \frac{1}{2}=\frac{c}{2}\Rightarrow 2*\frac{1}{2}=2*\frac{c}{2}\Rightarrow c=1\\sin(60^0)=\frac{b}{2}\Rightarrow \frac{\sqrt{3}}{2}=\frac{b}{2}\Rightarrow b=\sqrt{3}\Rightarrow\: b\approx \:1.73$

Once one leg is found there is another way to find the other leg, using Pythagorean Theorem too.

$a^{2}=b^{2}+c^{2}\Rightarrow 2^{2}=b^{2}+1^{2}\Rightarrow 4-1=b^{2}\Rightarrow b=\sqrt{3} b\approx 1.73$

Sides

a hypotenuse: 2.00

-------------------------------

b leg: 1.73

--------------------------------

c leg: 1.00
