What is the length of AC?

Otrada [13]

Answer:

Length of AC = <u>12units</u>.

Step-by-step explanation:

$\sf\large{\star Given:-}$

Hypotenuse of the triangle = $\sf\pink{10\:units.}$
Height of the triangle = $\sf\pink{8 \: units.}$

$\sf\large{\star To\: Find:-}$

$\rightarrow$ Base of the triangle.

$\sf\large{\star Solution:-}$

$\rightarrow$ As we know that,

Pythagoras Theorem:

$\sf\blue{Hypotenuse^2\:=\: Height^2+Base^2}$

So, In triangle ABD by putting the value of hypotenuse and height in this formula we get,

$\rightarrow$ $\sf{10^2\:=\: 8^2 + Base^2}$

$\rightarrow$ $\sf{100\:=\: 64 + Base^2}$

$\rightarrow$ $\sf{100-64\:=\: Base^2}$

$\rightarrow$ $\sf{36\:=\: Base^2}$

$\rightarrow$ $\sf{\sqrt{36}\:=\: Base}$

$\rightarrow$ $\sf{6\:=\: Base}$

Since, it is given that BD is the perpendicular bisector of AC so length of AC will be doubled.

Therefore, length of AC of the given triangle = $\sf\purple{12units.}$

Simplify the following expression. 4a^-2b<br><br> A.) b/4a^2<br> B.)4b/a^2<br> C.)1/4a^b2

Sergio [31]

ANSWER

The correct answer is B

$\frac{4b}{ {a}^{2} }$

EXPLANATION

The given exponential expression is

$4 {a}^{ - 2} b$

We can rewrite this as,

$4b \times {a}^{ - 2}$

We need to simplify to obtain a positive index, so we apply the following property,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

This implies that,

$4b \times {a}^{ - 2} = 4b \times \frac{1}{ {a}^{2} }$

This will finally simplify to,

$4b \times {a}^{ - 2} =\frac{4b}{ {a}^{2} }$

Therefore the correct answer is B
