The two triangles below are similar. What is the similarity ratio of ∆ABC to ∆DEF?
Schach [20]

Answer:

Option C is correct

Step-by-step explanation:

The two triangles are similar if there sides are proportional to each other

So, In Triangle ABC and Triangle DEF

AB/DE=BC/EF=AC/FD

according to definition of similar triangles.

We are given AC = 8

and FD = 4

So, AC/FD = 8/4 = 2/1

or 2:1

So, Option C is correct

Rewrite the following without an exponent. 6^-2<br> Please answer ASAP!
julia-pushkina [17]

Answer:

Rewriting 6^{-2} without an exponent we get \mathbf{\frac{1}{36}}

Step-by-step explanation:

We need to rewrite the following without an exponent. 6^{-2}

We need to solve the exponent to find the result.

We know the exponent rule: a^{-b}=\frac{1}{a^b}

Now using this rule to solve the equation:

6^{-2}\\=\frac{1}{6^2}\\We \:know \:that\:6^2 = 6\times 6=36\\=\frac{1}{36}

So, Rewriting 6^{-2} without an exponent we get \mathbf{\frac{1}{36}}

Find the inverse of the function x2 + y2 = 4 and the domain of the inverse for 0 ≤ x ≤ 2.
alexandr402 [8]
To get the inverse "relation" of an expression, we first off, do a quick switcharoo of the variables, and then solve for "y", so let's proceed,

\bf x^2+y^2=4\qquad inverse\implies \boxed{y}^2+\boxed{x}^2=4&#10;\\\\\\&#10;y^2=4-x^2\implies y=\pm\sqrt{4-x^2}

and yes, the domain for the range 0 ⩽ x <span>⩽ 2, let's get instead the "range" of the original function,

</span>\bf x^2+y^2=4\implies 0^2+y^2=4\implies y=\pm\sqrt{4}\implies \boxed{y=\pm 2}&#10;\\\\\\&#10;x^2+y^2=4\implies 2^2+y^2=4\implies 4+y^2=4\implies \boxed{y=0}\\\\&#10;-------------------------------\\\\&#10;\stackrel{\textit{range of original}}{-2\le y \le 2}~~=~~\stackrel{\textit{domain of its inverse}}{-2\le x \le 2}<span>
