21.325 is the correct answer
Answer:
x = ≈4.78
Step-by-step explanation:
25.1226x / 7.85 = 15.3
25.1226x = 15.3 × 7.85
25.1226x = 120.105
divise by 25.1226 to isolate x
x = ≈ 4.78
The value of (f· g)(x) from the given functions is
.
The given functions are f(x)=x³+x+1 and g(x)=-x.
<h3>What is the function?</h3>
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here,
(f·g)(x)= f(x) × g(x)
= (x³+x+1) × (-x)
= ![-x^4-x^2-x](https://tex.z-dn.net/?f=-x%5E4-x%5E2-x)
(g·f)(x)= g(x) × f(x)
= (-x) × (x³+x+1)
= ![-x^4-x^2-x](https://tex.z-dn.net/?f=-x%5E4-x%5E2-x)
Therefore, the value of (f· g)(x) from the given functions is
.

Answer:
Step-by-step explanation:
Of that list, only the square and the rectangle have the property you are asking for.
Try drawing it. The parallelogram has a shorter diagonal from the two obtuse angles than the diagonal from the two acute angles.
The rhombus has the same property as the parallelogram.
The kite has a far longer diagonal from the angle enclosed by the two long sides going to the angle enclosed by the two shorter sides, than a line going from the angle enclosed by one shorter and one longer side to the other angle made the same way.
Answer:
-8
Step-by-step explanation:
Perpendicular means negative reciprocal of the slope.
Negative reciprocal of 1/8 is -8.
