What is the perimeter of the rectangle

Answer:

(no global maxima found)

Step-by-step explanation:

Find and classify the global extrema of the following function:

f(x) = 4 x^4 - 2 x^3 + x - 5

Hint: | Global extrema of f(x) can occur only at the critical points or the endpoints of the domain.

Find the critical points of f(x):

Compute the critical points of 4 x^4 - 2 x^3 + x - 5

Hint: | To find critical points, find where f'(x) is zero or where f'(x) does not exist. First, find the derivative of 4 x^4 - 2 x^3 + x - 5.

To find all critical points, first compute f'(x):

d/( dx)(4 x^4 - 2 x^3 + x - 5) = 16 x^3 - 6 x^2 + 1:

f'(x) = 16 x^3 - 6 x^2 + 1

Hint: | Find where f'(x) is zero by solving 16 x^3 - 6 x^2 + 1 = 0.

Solving 16 x^3 - 6 x^2 + 1 = 0 yields x≈-0.303504:

x = -0.303504

Hint: | Find where f'(x) = 16 x^3 - 6 x^2 + 1 does not exist.

f'(x) exists everywhere:

16 x^3 - 6 x^2 + 1 exists everywhere

Hint: | Collect results.

The only critical point of 4 x^4 - 2 x^3 + x - 5 is at x = -0.303504:

x = -0.303504

Hint: | Determine the endpoints of the domain of f(x).

The domain of 4 x^4 - 2 x^3 + x - 5 is R:

The endpoints of R are x = -∞ and ∞

Hint: | Evaluate f(x) at the critical points and at the endpoints of the domain, taking limits if necessary.

Evaluate 4 x^4 - 2 x^3 + x - 5 at x = -∞, -0.303504 and ∞:

The open endpoints of the domain are marked in gray

x | f(x)

-∞ | ∞

-0.303504 | -5.21365

∞ | ∞

Hint: | Determine the largest and smallest values that f achieves at these points.

The largest value corresponds to a global maximum, and the smallest value corresponds to a global minimum:

The open endpoints of the domain are marked in gray

x | f(x) | extrema type

-∞ | ∞ | global max

-0.303504 | -5.21365 | global min

∞ | ∞ | global max

Hint: | Finally, remove the endpoints of the domain where f(x) is not defined.

Remove the points x = -∞ and ∞ from the table

These cannot be global extrema, as the value of f(x) here is never achieved:

x | f(x) | extrema type

-0.303504 | -5.21365 | global min

Hint: | Summarize the results.

f(x) = 4 x^4 - 2 x^3 + x - 5 has one global minimum:

Answer: f(x) has a global minimum at x = -0.303504

Answer:

12 people like to watch football

Step-by-step explanation:

The results are that 98 like to watch basketball, 12 like to watch football, and 2 dislike both.

Total number of residents = 100

Basketball (B) = 98

Football(F) = 12

Number of residents that like basketball and football = ( B ∩ F)

2 dislike both

n ( B ∪ F) - People that dislike it = n(B) + n ( F ) - n ( B ∩ F)

100 - 2 = 98 + 12 - n ( B ∩ F)

98 = 110 - n ( B ∩ F)

n ( B ∩ F) = 110 - 98

= 12

Therefore, 12 people like both Football and Basketball

How many like to watch football?

From the above question, we can see that the total number of people that like to watch football = 12 people

Answer:

0.00570776255

Step-by-step explanation:

there are 8760 hours in a year

divide 50 by 8760

0.00570776255

The number of earth quakes per hour is 5.7077.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

In one year = 50,000 occurs

In one year = 365 days

In 1 day = 24 hour

In 365 days= 8760 hours

So, number of earthquakes occurred in one hour

=50000/8760

=5.7077

Answer:

[tex]25\frac{1}{4}[/tex] feet

Step-by-step explanation:

Given

[tex]Maddy = 67\frac{3}{4}[/tex] above Jasmin

[tex]Jasmin = 42\frac{1}{2}[/tex] below Quinn

Required

Determine Maddy's position relative to Quinn's

From the given parameter, one can easily deduce that Quinn is in between Maddy and Jasmin (See attachment)

Using the attachment as a point of reference;

[tex]z = 67\frac{3}{4}[/tex]

[tex]x = 42\frac{1}{2}[/tex]

The relationship between x, y and z is

[tex]z = y + x[/tex]

Make y the subject of formula

[tex]y = z - x[/tex]

Substitute the values of z and x

[tex]y = 67\frac{3}{4} - 42\frac{1}{2}[/tex]

Convert to improper fractions

[tex]y = \frac{271}{4} - \frac{85}{2}[/tex]

Take LCM

[tex]y = \frac{271 - 170}{4}[/tex]

[tex]y = \frac{101}{4}[/tex]

[tex]y = 25\frac{1}{4}[/tex]

Hence; Maddy's position relative to Quinn's is [tex]25\frac{1}{4}[/tex] feet

Answer: 50%

To convert fractions into a percentage you Divide the Numerator and Denominator.

2÷4=0.5

Since the result came out as a decimal we convert it to a percentage.

As you can see 5 is in the tenth place so that means 0.5 as a percent is 50%

[tex]f(0)=3(0)+1[/tex]

[tex]f(0)=1[/tex]

Answer: (3,4)

Step-by-step explanation:

To find the midpoint, you want to use the formula [tex]m=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]. Since we are given the two points, we can plug them in and solve.

[tex]m=(\frac{-1+7}{2} ,\frac{9+(-1)}{2} )[/tex]            [add numerator]

[tex]m=(\frac{6}{2} ,\frac{8}{2} )[/tex]                          [divide]

[tex]m=(3,4)[/tex]

Now, we know that the midpoint is (3,4).

Answer:

Step-by-step explanation:

the volume of the triangular prism is 1/2*3.2*5.4*6

Answer:

C

Step-by-step explanation:

The volume (V) of the triangular prism is calculated as

V = Al ( A is the area of the triangular end, l is the length )

A = [tex]\frac{1}{2}[/tex] bh ( b is the base, h the perpendicular height )

Here b = 5.4 and h = 3.2 , thus

A = 0.5 × 5.4 × 3.2 = 8.64 cm² , then

V = 8.64 × 6 = 51.84 cm³ → C

Answer:

-3

Step-by-step explanation:

6x take 4x equals 2x

So it'll be 2x+4=-2

Then you do - 2 take 4 which is - 6

So then it is 2x=-6

-6÷2=-3

Hope this helps you :)

Answer:

x=-3

Step-by-step explanation:

6x+4=4x-2

Subract the x on the right side on both sides

Equation should now be:

2x+4=-2

Now subtract the 4 from both sides

The equation is now:

2x=-6

Now all you have to do is divide the x on both sides

Your answer is now x=-3

Answer:

19:95

Step-by-step explanation:

Spanish club have 19 students

Baseball have 24 students

Drama have 15 students

Home work help have 17 students

Soccer have 20 students

The first step is to calculate the total number of students

= 19 + 24 + 15 + 17 + 20

= 95 students

Since the Spanish club have 19 students and the total number of students is 95 then, the ratio which compares the number of students in Spanish club to the total number of students is 19:95

Answer: 19:95, 19 to 95, or 19/95. They all equal the same so it depends which one is your option. ORDER OF RATIO MATTERS!!

Explanation: The students in the Spanish club are 19 and to find the total number of students, you add 19 + 24 + 15 + 17 + 20 which equals 95. Then you put 19 first then 95. This is because it asked to compare the number of students in the Spanish clubs (so this is first) to the the total number of students (so this is second).

Answer:

70feet

Step-by-step explanation:

during the

1st sec it travels 28 ft

2nd sec =28-7=21ft

3rd sec= 21-7=14ft

4th sec= 14-7= 7ft

last sec=7-7=0ft, at this point the car stops.

so altogether it travels 28+21+14+7+0= 70 feet

Answer: 86.6ft closer to the ground.

Step-by-step explanation:

The diameter of the wheel is 200ft

Then the radius, half of the diameter, is: r = 200ft/2 = 100ft.

Initially, the seat is at the same level that the center of the wheel.

And the distance between the center of the wheel and the bottom is the radius.

Then the initial position is at an angle of 0° from the x-axis. (where the (0,0) of this axis coincides with the center of the wheel=

Now, the wheel rotates 60°. (downwards, so we actually could use -60° measuring from the positive x-axis)

And thinking in this as a triangle rectangle, where the opposite angle is 60°, we can calculate the displacement in the vertical direction as:

y = sin(-60°)*R

y = sin(-60°)*100ft = -86.6ft

So the seat is 86.6ft closer to the ground.

The seat is [tex]86.6feet[/tex] closer to the ground

The seat will be closer by the height it drops when the Ferris wheel turns downwards by [tex]60^{\circ}[/tex].

The height, and the radius of the Ferris wheel form the opposite and the hypotenuse of a [tex]60^{\circ}[/tex] right-angled triangle. Since the diameter of the Ferris wheel is 200feet, the radius will be 100feet. So we have

[tex]sin60^{\circ}=\frac{opp}{hyp}=\frac{h}{100}\\\\h=100\times sin60^{\circ}\\=100\times 0.8660\\=86.6[/tex]

So the seat is [tex]86.6feet[/tex] closer to the ground
