If f(x) = 3x, what is f(4)?

Mathematics
1 answer:
dimulka [17.4K]3 years ago
3 0

Answer:

f(4) = 12

Step-by-step explanation:

Substituting 4 for x in f(x) = 3x, we get f(4) = 3(4) = 12.  We conclude that "the value of the function f(x) = 3x at x = 4 is 12."

Answer:

|F net| = 20.22 N

θ ≈ 19.8°

Step-by-step explanation:

F net = 15N i + 8cos(60°)N i + 8sin(60°)N j

= 15N i + 8×½N i + 8×√3/2N j

= 15N i + 4N i + 4√3N j

= 19N i + 4√3N j

|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N

tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°

What are the period and amplitude of the function?
umka2103 [35]

Answer:

The period of function is 5 and amplitude is 3.

Step-by-step explanation:

<em>The period of the function is the time interval after which it repeats itself.</em>

It means the time interval after which the same value of graph is attained.

In the above case looking at the peak point at time 5 seconds, the same value is obtained at time 10 seconds.

Thus the time interval is (10 - 5) 5 seconds.

<em>Amplitude is the maximum value attained by the graph in the complete interval.</em>

In the above case, the maximum value attained is 3.

german
By simple substitution on the left side and on the right side of the given equation, we have to
 For <span>coordinates (-3,-9)
 -9</span><span>=−8|-3+3|−9
 -9</span><span>=−8|0|−9
</span> -9=−9
 Therefore, it is demonstrated that<span> the coordinates of the vertex is
 (-3,-9)</span>
