Answer:

(-1, 2/3).

Step-by-step explanation:

Taking the derivative of f, we get f' = x^2 - 1 = 0.  Thus, x = -1 and x = +1.

At the relative max, y = (1/3)(-1)^3 - (-1) = -1/3 + 1 = 2/3.

The relative maximum is at (-1, 2/3).

step-by-step explanation:

v = (5.5)(4)(3.5)

v = 77 [tex]mm^{3}[/tex]

Answer:

Volume = 77mm

Step-by-step explanation:

Given the length, width and height find the volume

Volume = Length x Width x Height

4 x 5.5 x 3.5 = 77mm

Answer:

80 meters

Step-by-step explanation:

Length of rectangular field = x

Width of rectangular field = 50

Meters of Fencing required = perimeter of rectangle = 260 m

Perimeter of a rectangle = 2(length + width)

260 = 2(x + 50)

260 = 2x + 100

260 - 100 = 2x

160 = 2x

x = 160 / 2

x = 80 meters

Answer:

The answer is C

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the map or the scale length of the plants are not given.

To solve this, I will assume that:

[tex]Scale\ Distance = x[/tex]

[tex]Scale\ Ratio = 1\ unit : 1\ km[/tex]

Required

The total length

To get the total length (actual length), multiply the scale ratio by the scale distance;

[tex]Actual = Scale\ Distance * Scale\ Ratio[/tex]

So, we have:

[tex]Actual = x * 1km[/tex]

[tex]Actual = x\ km[/tex]

Assume that:

[tex]x = 5[/tex]

The total length will be:

[tex]Actual = 5km[/tex]

Answer:

53°

Step-by-step explanation:

[tex]m \angle1 = \frac{1}{2} (50 + 56) \degree \\ \\ = \frac{1}{2} \times 106 \degree \\ \\ = 53 \degree[/tex]

Step-by-step explanation:

Use the formula for compound interest

f/p: f =p(1+i)^n

p = 3300

i =8% = 0.08

n = 9 years

A = p(1+r)^t

A = 3300(1+0.08)⁹

A = 3300× 1.99

A= 6596.71 dollar ~ 6597 dollar.

Answer:

12

Step-by-step explanation:

18*2=36, 60-36=24, 24/2=12

The width of the room if the length is 18m is 1.66m.

We have given that,

Perimeter=60 and length=18m

P=2(l+w)

Where the l is the length and

W is the width

Perimeter=60 and length=18m.

Use this value in the formula of perimeter

60=2(18×W)

Divide both sides by 2

30=18w

isolate the w

Therefore, divide both sides by 18.

30/18=w

W=1.66m

Therefore the width of the room if the length is 18m is 1.66m.

solve for h

Answer:

Step-by-step explanation:

assuming that the triangles are similar,  which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.

' = feet

" = inches

h / 20' = 4'-2" / 3'-4"

just use inches for this,  it's easier

h / 240" = 50" / 40"

h = 240 ( 50 / 40 )

h = 300"

h = 25'

Answer = D

Step-by-step explanation:

If you add all of the heights up you get 480. divide that by ten (because there were 10 students whose height was taken) then you get 48. therefore, the typical second-grade student is about 48 inches tall.

I hope this helps have a good day :)

The typical second-grade student is about 48 inches tall.

'Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.'

According to the given problem,

Given data = { 44, 45, 47, 49, 48, 48, 49, 50, 48, 52 }

Sum of the given data = 44 + 45 + 47 + 49 + 48 + 48 + 49 + 50 + 48 + 52

                                     = 480

Average of the given heights = [tex]\frac{480}{10}[/tex]

                                                 = 48

Hence, we can conclude,  The typical second-grade student is about 48 inches tall since the average of the given data is 48.
