What is the range of possible sizes for side x? _ < x < _
allochka39001 [22]

Answer:

  0.5 < x < 16.5

Step-by-step explanation:

The third side of the triangle must be longer than the difference of the other two sides:

  x > (8.5 -8.0)

  x > 0.5

And it must be shorter than their sum:

  x < (8.5 +8.0)

  x < 16.5

The third side must be in the range ...

  0.5 < x < 16.5

_____

These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.

Which answer choice states the range of the following
ankoles [38]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.

Remember that for any relation, we have a set A that matches the the domain (also called the set of inputs) of the function and the set B that contains the range (also called the set of outputs).

Suppose our relation is:

y=-10+x \\ \\ For \ x=1,2,3,4,5

So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:

\text{If x=1} \\ \\ y=-10+1=-9 \\ \\ \\ \text{If x=2} \\ \\ y=-10+2=-8 \\ \\ \\ \text{If x=3} \\ \\ y=-10+3=-7 \\ \\ \\ \text{If x=4} \\ \\ y=-10+4=-6 \\ \\ \\ \text{If x=5} \\ \\ y=-10+5=-5

So in this context, the correct option is:

B) (-9,-8, -7, -6, -5}

If h(x) = x – 7 and g(x) = x2, which expression is equivalent (g o h)(5)
Zanzabum
(goh)(x) = (g(x))(h(x)) = (x^2)(x-7) = x^3 -7x^2
then (goh)(5) = (5^3)-7(5)^2 = 124-7(25) = 124-175 = -51
