Exponential equation is
y=a(b)ˣ
when b>1, it is growth
when 0>b>1, it is decay
so
we want the 2nd number to be more than 1
that would be the 3rd one, y=3(8)ˣ
Answer:
Step-by-step explanation:
-------------------------
Given:
---------->>>>
Combine like terms.
---------->>>>
Add 12 to both sides.
---------->>>>
Divide both sides by 9.
-------------------------
Hope this is helpful.
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)
x−12<3
Step 1: Add 12 to both sides.
x−12+12<3+12
x<15
