Answer:

u = \sqrt{6}.

Step-by-step explanation:

This is a 45-45-90 triangle.

That means that there are two side lengths with lengths of x, and a hypotenuse with a length of xsqrt(2). We can then set up a proportion.

\frac{1}{\sqrt{3} } =\frac{\sqrt{2} }{u}

1 * u = \sqrt{3} * \sqrt{2}

u = \sqrt{6}.

Hope this helps!

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

Suppose you have a pocketful of change. You have some pennies (p) and some quarters (q). One expression could be used to describ
faltersainse [42]

Answer:

13

1.57

Step-by-step explanation:

So we have two equations regarding the number of quarters <em>q</em> and the number of pennies <em>p:</em>

<em />p+q<em />

Which represents the total amount of coins and

0.01p+0.25q

Which represents the total amount of money in dollars.

So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for <em>q</em> and 7 in for <em>p:</em>

<em />p+q\\(7)+(6)=13<em />

This tells us that we have 16 coins in total.

0.01(7)+0.25(6)\\=0.07+1.50\\=1.57

This tells us that we have a total amount of $1.57.
