The correct format of the question is

If f(x)= [tex]\frac{1}{3}x^3 -4x^2+12x -5[/tex] and the domain is the set of all x such that 0≤x≤9 , then the absolute maximum value of the function f occurs when x is

Answer:

The absolute maximum value of the function F(x) occurs when x is 9

Step-by-step explanation:

F'(x) = [tex]x^2 -8x +12= 0[/tex]

      = (x-6)(x-2) = 0

      x = 2,6

so we have boundary points 0 , 9 and 2,6

The value of function at these four points

  x =     0    2       6     9

F(x) =  -5    17/3   -5     22

So the absolute maximum value of the given function is x = 9 and F(x) is 22.

The absolute maximum value of the function f occurs when x is 9 and this can be determined by differentiating f(x) and then equating it to zero.

Given :

In order to determine the absolute maximum value of function f(x), differentiate f(x) and then equate it to zero.

[tex]\rm f'(x)=\dfrac{1}{3}\times(3x^2)-8x+12[/tex]

Now, equate the above equation to zero.

[tex]x^2-8x+12 = 0[/tex]

Factorize the above quadratic equation.

[tex]x^2-6x-2x+12=0[/tex]

x(x - 6) - 2(x - 6) = 0

(x - 6)(x - 2) = 0

Now, determine the value of f(x) at x = 0, 2, 6, 9

f(0) = -5

f(2) = 1/3.(8) - 4(4) + 12(2) - 5

f(2) = 17/3

f(6) = 72 - 144 + 72 - 5

f(6) = -5

f(9) = 243 - 324 + 108 - 5

f(9) = 22

So, the absolute maximum value of the function f occurs when x is 9.

The number of stickers did each student receive get is 12, 18 and 30 respectively.

Given that, a teacher divided 60 stickers among 3 students in a ratio of 2:3:5.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Here, 2+3+5=10

Number of stickers student 1 get

= 2/10 × 60

= 12

Number of stickers student 2 get

= 3/10 × 60

= 18

Number of stickers student 3 get

= 5/10 × 60

= 30

Therefore, the number of stickers did each student receive get is 12, 18 and 30 respectively.

Answer:

On melissa's 6th birthday, she gets a $4000 cd that earns 3% interest, compounded quarterly. If... | like | dislike ... The amount accumulated in a certificate of deposit (CD) is found using the compound interest formula as a CD also earns compounding interest. ... The number of years between the 6th and 12th birthdays is 6

Step-by-step explanation:

There will be $41142.87 available on Melissa's 16th birthday.

Interest accrued on both the principal sum of money and the interest already earned.

The formula for compound interest is p(1+r/100)ⁿ - p

Where p is principal, r is rate and n is time.

Given that,

Amount that Melissa gets on her 6th birthday = $4000

Rate of interest = 6% compounded quarterly.

Melissa gets amount on her 16th birthday, time = 6 years

The amount that Melissa will get on her 16th birthday

= 4000(1+6/100)¹⁰ˣ⁴

= 4000 (106/100)⁴⁰

= 4000 x 10.2857

= 41142.87

Melissa will get $41142.87 on her 16th birthday.

Answer:

Time to land on 11ft is 4.25 seconds

Step-by-step explanation:

Given

[tex]y = 300 - 16t^2[/tex]

Required

Solve for t when height is 11ft

This implies that [tex]y = 11[/tex]

So: substitute 11 for y in [tex]y = 300 - 16t^2[/tex]

[tex]11 = 300 - 16t^2[/tex]

Collect Like Terms

[tex]16t^2 = 300 - 11[/tex]

[tex]16t^2 = 289[/tex]

Express both sides as squares

[tex]4^2 * t^2 = 17^2[/tex]

[tex](4t)^2 = 17^2[/tex]

Take square roots of both sides (ignore negative)

[tex]4t = 17[/tex]

Solve for t

[tex]t = \frac{17}{4}[/tex]

[tex]t = 4.25[/tex]

Hence, time to land on 11ft is 4.25 seconds

Answer: There are none to choose from

Step-by-step explanation:

Answer:

A=30t+200

B=50t+100

The number of hours,t, that would make the cost of each company the same is 5.

30(5)+200= A

  150+200=350

50(5)+100= B

  250+100=350

Step-by-step explanation:

The time required in hours for the cost for both the companies to be the same is 5 hours.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

From the given information the total cost C in terms of t for company A is,

C = 30t + 200 and for company B is, C = 50t + 100.

Therefore, the number of hours when  the cost of each company would be the same is,

30t + 200 = 50t + 100.

30t - 50t = 100 - 200.

- 20t = - 100.

20t = 100.

t = 10/2.

t = 5 hours.

PART A:

Finding the slope of the function f(x)

Choose any two pairs of coordinate from the table; (-1, -15) and (0, -10)

Let (-1, -15) be (x₁, y₁) and (0, -10) be (x₂, y₂)

Slope =

Slope of f(x) = 5

The function g(x) is given in the straight line equation form

Where,  is the slope and  is the y-intercept

Slope of g(x) = 2

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

g(x) = 2x + 8

Where, the slope (m) = 2 and the y-intercept (c) = 8

The y-intercept of g(x)  is 8

for f(x), we can read the y-intercept when x = 0.

From the table, when x = 0, y = -10

The y-intercept of f(x) is -10

Function g(x) has higher y-intercept

Step-by-step explanation:

Part 1

Pizzas sold last day = 65

Increasement needed in sale = 20%

pIzzas to be sold today

= 65 + 20% of 65

= 65 + 20/100 × 65

= 65 + 1/5 × 65

= 65 + 1/1 × 13

= 65 + 13

= 78

Part 2

Pizzas sold last day = 65

Pizzas sold today = 60

60 = 65 + x% of 65

60 = 65 + x/100 × 65

60 - 65 = x/20 × 13

- 5 = x/20 × 13

-5/13 = x/20

-5/13 × 20 = x

-7.692 = x

Therefore, there was a decrease in pizza sale by 7.692%

By rounding off,

The decrease in pizza sale was by 7.700%.

= 7.7%
