Given the following polynomial find the maximum possible number of turning points. f(x)=x^11+x^10+x^12+x^9

11111nata11111 [884]

Turning points are inflection points

think
1st degree (linear) has no turning/inflecion points
2nd degree (quadratic, parabola) has 1 turning/inflection point
so
nth degree has n-1 turning/inflection point

this is 11th degree since highest power is 12
12-1=11
11 turning oints

geniusboy [140]

Answer: (5,10)

Step-by-step explanation:

multiply first equation with 2 and add it to second to eliminate X

7x-5y=-15 //*2

14x-10y=-30

-14x+7y=0

----------------

-3y=-30

y=-30/-3

y=10

7x=50-15

7x=35

x=35/7

What is the value of x? A. 4 B. 4√3 C. 8 D. 8√3

SashulF [63]

Answer:

B. 4√3

Step-by-step explanation:

$\sin \: 60 \degree = \frac{x}{8} \\ \\ \therefore \: \frac{ \sqrt{3} }{2} = \frac{x}{8} \\ \\ \therefore \: x = \frac{8 \times \sqrt{3} }{2} \\ \\ \therefore \: x = 4 \times \sqrt{3}\\ \\ \huge \purple{ \boxed{ \therefore \: x = 4 \sqrt{3} }}\\$
