Which expression is equivalent to the given expression? Assume the denominator does not equal zero.

ipn [44]

The expression equivalent to given expression is $\frac{b^4}{a}$

<em><u>Solution:</u></em>

Given expression is:

$\frac{a^3b^5}{a^4b}$

We are asked to find the expression equivalent to given expression

Assume that denominator does not equal to zero

We can apply the exponent rule in given expression

$\frac{x^a}{x^b} = x^{a - b}$

Apply the above rule in given expression

$\frac{a^3b^5}{a^4b} = a^{3-4} \times b^{5-1} = a^{-1}b^4$

$a^{-1}b^4 = \frac{b^4}{a}$

Thus the equivalent expression is found

The circumference of a circle is 11 inches. What is the area, in square inches, of the circle? Express your answer in terms of p

kakasveta [241]

Answer

A = 30.25pi. PLS GIVE BRAINLIEST

Step-by-step explanation:

so if circumference is 11, and formula for circumference is 2pi*r, we can work backwards to find the radius.

Radius: 11pi/2 = 5.5pi = 5.5 is radius

Area = pi * r^2

so Area = pi*5.5^2

so A = 30.25pi left in terms of pi

The statements below can be used to prove that the triangles are similar. ? △ABC ~ △XYZ by the SSS similarity theorem. Which mat

Vsevolod [243]

Solution:

It is given that two triangles Δ ABC and Δ X Y Z are similar by Side -Side - Side(SSS) Similarity theorem.

So, the Statement which is given, that is →→∠B ≅ ∠Y and ∠B ≅ ∠Z, is inadequate for similarity criterion by SSS, as these statement are about angles of Triangles,not sides, which can't be true.

So, if the two triangles are Similar by SSS criterion , then the appropriate mathematical statement must be,

⇒ $\frac{AB}{XY}=\frac{BC}{ZY}=\frac{AC}{XZ}$
