d)
First choice is an improper fraction because you can't have 22 ninths.
And the second two are just normal fractions, not wholes.
The first choice would be the right answer IF instead of writing it like that, it was written like this ( 2 4/9 )
Your answer is d).
Answer:
x^2+15x+7
Step-by-step explanation:
There are no like terms.
2/5 or 0.4 Because only two of the five numbers are even or greater than 78
d/dx cos^2(5x^3)
= d/dx [cos(5x^3)]^2
= 2[cos(5x^3)]
= - 2[cos(5x^3)] * sin(5x^3)
= - 2[cos(5x^3)] * sin(5x^3) * 15x^2
= - 30[cos(5x^3)] * sin(5x^3) * x^2
Explanation:
d/dx x^n = nx^(n - 1)
d/dx cos x = - sin x
Chain rule:
d/dx f(g(...w(x))) = f’(g(...w(x))) * g’(...w(x)) * ... * w’(x)
