Select the correct answer. what are the approximate values of the minimum and maximum points of f(x) = x5 − 10x3 + 9x on [-3,3]? a. maximum point: (–2.4, 37.014) and minimum point: (2.4, –37.014) b. maximum point: (2.4, –37.014) and minimum point: (–2.4, 37.014) c. maximum point: (–1.4, 33.014) and minimum point: (1.4, –33.014) d. maximum point: (–3, 30) and minimum point: (3, –30)

Take the first derivative to find critical points:

or approximately (from least to greatest) -2.4, -0.56, 0.56, 2.4.

We have second derivative

and at each of the critical points, we have

The signs of the second derivative at each point indicates a local minima at and , and local maxima at and . At these extrema, we have

and at the endpoints of the interval, we have

So the answer is A.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
