Compute the following radical.<br> sq root 144
lara31 [8.8K]

we are given

\sqrt{144}

Firstly, we will find all possible factors of 144

144=2\times 2\times 2\times 2\times 3\times 3

we can also write as

144=(2\times 2)^2\times (3)^2

now, we can put exponent to over entire term

144=(2\times 2\times 3)^2

now, we can replace 144

\sqrt{144}=\sqrt{(2\times 2\times 3)^2}

now,  sqrt will get cancelled with square

and we get

\sqrt{144}=(2\times 2\times 3)

now, we can simplify it

\sqrt{144}=(4\times 3)

\sqrt{144}=12.............Answer

A hotel offers a reward program based on the number of night stayed. The function f(x) represents the number of free nights earn
iris [78.8K]

Answer:

a. A customer earns 1 free night per 10 nights stayed.  

Step-by-step explanation:

The missing function is:

f(x) = x/10  

The missing options are:

<em> a. A customer earns 1 free night per 10 nights stayed.  </em>

<em> b. A customer starts with 1 free night and then earns another free night after every 10 nights stayed. </em>

<em> c.A customer earns x – 10 free nights for every 10 nights stayed.  </em>

<em> d. A customer earns 10 free nights after x number of nights stayed. </em>

The function means that after a customer stayed 10 nights, a free night is earned. That is, replacing x = 10 into the function, we get:

f(10) = 10/10  = 1

which means 10 nights are equivalent to 1 free night.

What is the value of k?
Romashka-Z-Leto [24]

Answer:

k = 10

Step-by-step explanation:

The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.  

So 10k + 15 must equal the remaining 115

subtract 15 from each side and you get 10k = 100

divide each each by 10 and you get the answer of k = 10

Isolate x:

-4x = -200 - 104 = -304

x = -304/-4 = 76
