Find the critical points and determine if the function is increasing or decreasing on the given intervals.y = 9x^4 + 10x^3Left c
lina2011 [118]
y=9x^4+10x^3

To find the critical points, first we derivate the function:

\frac{dy}{dx}=36x^3+30x^2

dy/dx has roots x = 0 and x = -5/6.

When x < -5/6, we can check that dy/dx is negative. When -5/6 < x < 0, we can check that dy/dx is positive. And, when x > 0, we can check that dy/dx is also positive.

Therefore, y is increasing when x > -5/6 and decrasing when x < -5/6. y has inflection points at x = -5/6 and x = 0

3 A new club opens with 20 members, plus an unknown number of members from another club. The club allows only members to join on
Marina86 [1]

Step-by-step explanation:

let the unknown members be X

At first, the club had 20 + X members

After the first year,

2( 20+X)

The second year,

2( 20 +X/2) +40

The third year,

3[2(20+ X/2) +40]

Total number =

20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]

= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]

= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]

= 60 +3X +80+X + 3[80+X]

= 140+4X + 240+3X

=380 + 7X

-380=7X

X = -54.3
