if we take 30 to be the 100%, what is 27 off of it in percentage?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 30 & 100\\ 27& x \end{array} \implies \cfrac{30}{27}=\cfrac{100}{x} \\\\\\ \cfrac{10}{9}=\cfrac{100}{x}\implies 10x=900\implies x=\cfrac{900}{10}\implies x=90$

What is the simplified base for the function f(x) = 2rootindex 3 startroot 27 endroot superscript 2 x?

VMariaS [17]

Applying exponential properties, the simplified base for the function is given as follows:

$f(x) = 2(3)^{2x}$

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

The function is represented by the following definition:

$f(x) = 2\sqrt[3]{27^{2x}}$

As an exponent, the function is given by:

$f(x) = 2(27)^{\frac{2x}{3}}$

27 can be simplified as follows:

27 = 3 x 3 x 3 = 3³

Hence:

$f(x) = 2(3^3)^{\frac{2x}{3}}$

Then, the 3 at the exponent multiplies 2x and can be simplified with the 3 of the root, hence:

$f(x) = 2(3)^{\frac{3 \times 2x}{3}} = 2(3)^{2x}$

Hence the simplified base for the function is given as follows:

$f(x) = 2(3)^{2x}$

A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Which statement about the quadrilateral is true?

Aleksandr-060686 [28]

Answer: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Find:

You can see that vectors and This means that opposite sides are parallel and option B is false.

Find the lengths of all sides:

As you can see the lengths of opposite sides are equal, but all lengths are not equal. Therefore, the last option D is false.

Now check whether angles A and B are perpendicular:

The dot products are not equal to zero, then angles A and B are nor right. This means that option C is false and option A is correct (ABCD is a parallelogram with non-perpendicular adjacent sides

AKA your correct awnser choice is A :)✨

Some ppl might think this is easy

ratelena [41]

Point-slope form: y - 5 = (-1/5)(x - 7)

standard form: x + 5y = 7

slope-intercept form: y = (-1/5)x + (7/5)
***note: (-1/5) = -0.2 and (7/5) = 1.4
