Si f(x) = 1/2x^2-(1/4x+3),¿cuál es el valor de f(8)?<br> (3) 27<br> (2) 17<br> (4) 33<br> (1) 11
gavmur [86]

Answer:

27

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = \frac{1}{2} × 8² - (\frac{1}{4} × 8 + 3)

     = \frac{1}{2} × 64 - (2 + 3)

     = 32 - 5

     = 27

In ΔLMN, \overline{LN}
Karolina [17]

Answer:

\bold{\angle NLM = 10^\circ}

Step-by-step explanation:

Given a ΔLMN.

Line LN is extended to point O.

such that:

\text{m}\angle MNO = (5x-13)^{\circ}

\text{m}\angle NLM = (x-4)^{\circ} and

\text{m}\angle LMN = (2x+19)^{\circ}

To find:

\text{m}\angle NLM=?

Solution:

Kindly refer to the attached image for the given triangle and dimensions of angles.

Let us recall the external angle property of a triangle:

The external angle of a triangle is equal to the sum of two opposite internal angles.

i.e.

\angle MNO = \angle NLM + \angle LMN\\\Rightarrow 5x-13 = x-4+2x+19\\\Rightarrow 5x-13 = 3x+15\\\Rightarrow 5x-3x = 13+15\\\Rightarrow 2x=28\\\Rightarrow x =14

Putting the value of x in \angle NLM.

\angle NLM=14-4 \\\Rightarrow \bold{\angle NLM = 10^\circ}

What is the range of the function on the graph?all real numbersO all real numbers less than or equal to -1all real numbers less
Yuki888 [10]

The range of the function f(x) is the set of all values that function f takes.

The domain of the function f(x) is the set of all possible values for x.

From the given graph you can see that the domain is all real numbers, x\in (-\infty,\infty).

The maximal y-value that f takes is 3 at x=-1. For all another x from the domain, y is less than 3.

Thus, the range of the given function is y\in (-\infty,3].

Answer:  y\in (-\infty,3].
