Given the following polynomial find the maximum possible number of turning points. f(x)=x6+x2+x7+x12

1 answer:

8 0

If you put in descending order you get:
f(x) = x^12 + x^7 + x^6 + x^2
The highest power (n) is 12 so the maximum number of turning points is (n - 1), 12 -1 = 11
You can have 11 turning points

Answer:

It will be the graph of two lines intersecting at two comma three with text on graph that reads One Solution 2, 3.

Step-by-step explanation:

The system of equations are

y - 2x = - 1 ............ (1) and

2y - x = 4 ........... (2)

Now, solving equations (1) and (2) we get,

2(2x - 1) - x = 4

{Substituting the value of y from equation (1) to equation (2)}

⇒ 4x - 2 - x = 4

⇒ 3x = 6

⇒ x = 2

Hence, from equation (1) we get,

y = 2x - 1 = 2(2) - 1 = 3

Therefore, the solution is (2,3).

So, it will be the graph of two lines intersecting at two comma three with text on the graph that reads One Solution 2, 3. (Answer)

Madie drove 200 miles at a speed of 50 miles per hour. Which equation will help you find the number of hours she was driving? St

aalyn [17]

Answer:

StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction

Step-by-step explanation:

For constant speed, miles and hours are proportional. One possible equation is ...

$\dfrac{50\,\text{miles}}{1\,\text{hour}}=\dfrac{200\,\text{miles}}{?\,\text{hours}}\qquad\text{matches the first choice}$

_____

Comment on the solution

I personally like to put the unknown in the numerator, so the equation can be solved in one step. The equation above requires two steps: one to cross-multiply, and one to divide by 50.

I might write the equation as ...

(? hours)/(200 mi) = (1 hour)/(50 mi) . . . . multiply by 200 mi to solve

Another way to write the equation is matching the ratios of times to corresponding miles:

(? hours)/(1 hour) = (200 mi)/(50 mi)

This only requires simplification to solve it: ? = 4.

(Drinking and driving.) Just after Eric had his last drink, the alcohol level in his bloodstream was 0.20 (milligram of alcohol

Here's the formula for exponential decay:

$A = p(1-k)^t$

(where A = new amount, p = principal (starting) amount, k = rate of decay, and t = time)

Let's use what we know and fill in the expression.

$0.08 = 0.20(1-0.47)^t$

And now we solve for t.

$0.08 = 0.20(0.53)^t \\ 0.4 = 0.53^t \\ log0.4=t*log0.53 \\ t = \frac{log0.4}{log0.53} = \boxed{1.44\ hours}$
