Answer:

<h2>Lenght of the third side =12</h2>

Step-by-step explanation:

hypotenuse = 13 \\ opposite = 5 \\ adjacent = x \\  {hyp}^{2}  =  {opp}^{2}  +  {adj}^{2}  \\

{13}^{2}  =  {5}^{2}  +  {x}^{2}  \\ 169 = 25 +  {x}^{2}  \\ 169 - 25 =  {x}^{2}  \\ 144 =  {x}^{2}

\sqrt{144}  =  \sqrt{ {x}^{2} }  \\ 12 = x

Answer:

If the third side is the hypotenuse, then (using the Pythagorean Theorem) the square of its length is the sum of the squares of the other two sides:  132+52 , so the length of the hypotenuse is √194=13.92838827718412...  

However, it is also possible to have a right triangle with a hypotenuse of 13 cm and one side of 5 cm, in which case the third side would be:  √132−542=12.  

Of course, the second answer may seem “nicer” but both are correct and the question is ambiguous.

If log(base4)x=2.5 and log(base Y)125=-3/2, find the numerical value of x/y, in simplest form.
Naya [18.7K]
X = (2^2)^(2.5) 
<span>x = 2^(2 * 2.5) </span>
<span>x = 2^5 </span>
<span>x = 32 
</span>y^(-3/2) = 125 
<span>y^(-3) = 125^2 </span>
<span>y^(-3) = (5^3)^2 </span>
<span>y^(-3) = (5^2)^3 </span>
<span>y^(-3) = 25^3 </span>
<span>y = 25^(-1) </span>
<span>y = 1/25 </span>


<span>x/y => </span>

Sophie [7]

Answer:

a= 336 different ways

b= 10 possible combinations

Step-by-step explanation:

As it is a definite machine and it must have ordered combinations therefore it is a permutation question . So finding 3 out of eight

8 P 3= 336  different ways the eight machines be arranged in the three spaces available.

Since the parts are randomly selected and there is no distinct pattern therefore combinations is used to solve this.

5C2 = 10 possible combinations of two parts can be selected.
