Answer:

k=20.

Explanation: First we find where f(x) has its local extrema: f'(x)=3x2−10x+3. The critical points are roots of the equation: 3x2−10x+3=0.

A question on notation: Does sine inverse have an exponent? If not, why is there a negative one there? If so, why can't you just
NNADVOKAT [17]

Answer:

Step-by-step explanation:

When you write

          -1

y = sin    x, the "-1" is not an exponent, but rather an indication of "inverse function."

          -1

y = sin    x      can also be written as     y = arcsin x.

No exponentiation here, and no division here.

Vera_Pavlovna [14]

The margin of error is ±2%

<h3>What is Margin error?</h3>

A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.

Let x be margin of error and y be the percentages of the population.  

So,

y-x =33%

y +x = 37%

Solving above equations

2y= 70

y= 35%

and x= 2%

Hence, the margin of error is ±2%.

D/13&gt;-3<br><br> A. D&gt;-16<br> B. D&gt;39<br> C. D&gt;10<br> D. D&gt;-39<br><br> Help?
mylen [45]
D/13>-3

You have to multiply 13 in both sides to eliminate the Denominator 13 on the left leaving variable D only.
(D/13)(13) > -3(13)

D > -39

so... D. D > -39
