What is the perimeter of the triangle? units

Mathematics

Answer:

30 units

Step-by-step explanation:

The perimeter of the triangle is the sum of the two legs, or the shorter sides <em>a</em> and <em>b</em>, and the hypotenuse, the last and longest side, <em>c</em>.

We can already see that side <em>a </em>and <em>b</em> have the lengths of 5 and 12 units.

To find the length of <em>c</em>, use the formula <em>a² + b² = c²</em>.

Substitute our <em>a </em>and<em> b </em>values into the formula and solve for <em>c</em>.

<em>a² + b² = c²</em>

<em>5² + 12² = c²</em>

<em>25 + 144 = c²</em>

<em>169 = c²</em>

<em>√169 = √c²</em>

<em>13 = c</em>

The third side is 13 units long.

Now we can add our values for <em>a</em>, <em>b</em>, and <em>c</em> together to find the perimeter.

<em>5 + 12 + 13 = P</em>

<em>30 = P</em>

The perimeter is 30 units.

Good luck ^^

Given that f(a+b)= f(a) + f(b) and f(x) is always positive, what os the value of f(0)?
FrozenT [24]
This is a strange question, and f(x) may not even exist. Why do I say that? Well..

[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).

[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!

Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.

To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.

Which is not true about the random sample method?
USPshnik [31]

B. The sample is likely to represent one portion of the population.

This is impossible to say because it's random.
