Answer:
Answer:
Option 2nd is correct.
=0.
Step-by-step explanation:
Given the function:
Solve:
First calculate:
f[g(x)]
Substitute the function g(x)
Replace x with x-8 in the function f(x) we get;
The distributive property says that:
Using distributive property:
⇒
Put x = 6 we get;
Therefore, the value of is 0.
Step-by-step explanation:
Why this is so easy
Ok so, 75/5=15
15*7 =105 so the answer is 105 pages
Let x = the length of the rectangle
Let w= the width
Two sections are required, hence 2w of fence required
2x+3w=500
this can be written as:
3w=1500-2x
w=(1500-2x)/3
Area=x*w
replacing w with our expression:
A=x(1500-2x)/3
A=(500x-2x^2)/3
This is a quadratic equation, if we find the axis of symmetry we will know what value of x gives maximum area:
Axis of symmetry: x=-b/2a
From our equation we get:
a=-2/3; b=1500/3
thus
x=(1500/3)/(-(-2/3))
x=750
thus the maximum area will be given by length of 750
The correct answer for this question is letter "<span>D. (x) / (sqrt (1+x^2))."

Make a triangle. yes a triangle. label "opposite" side x and adjacent side 1 since the tangent is x = x/1
use pythatoras to find the hypotenuse which will be
square root (1 + x^2)
then
<span>sin(ta<span>n<span>−1</span></span>(x)<span>) = x / (square root (1 + x^2))
</span></span>
that being opposite over hypotenuse
and by the same triangle
<span>cos(ta<span>n<span>−1</span></span>(x)) = </span>x / (square root (1 + x^2))
