A function is classified as exponential if when the input variable is changed by one, the output variable is multiplied by a constant.

Hence, in this problem, the function g(x) is exponential, as when the input x is increased by one, the output g(x) is multiplied by two.

A function is classified as linear if when the input variable is changed by one, the output variable is increased/decreased by a constant.

Hence, in this problem, the function f(x) is linear, as when the input x is increased by one, the output f(x) is increased by a constant of six.

The dimensions of the rectangular garden which minimize the cost is equal to 9.6ft and 14.6ft respectively.

As given in the question,

Cost of brick wall is equal to $40/ft

Cost of metal fencing is equal to $20/ft

Let 'x' and 'y' are the dimensions of the rectangular garden

Area of the rectangular garden = 142 square feet

⇒ 142 = xy

⇒x = 142/y

Costing of four side fencing 'C' = 40x + 20x + 20y + 20y

⇒ C = 60x + 40y

⇒C = 60(142/y) + 40y

⇒C = 8520/y + 40y

Differentiate with respect to y

dC/dy = -8520/ y² + 40

Put dC/dy = 0

-8520/ y² + 40 = 0

⇒y² = 8520/40

⇒y = √213

⇒ y= 14.6 ft

⇒ x= 142/14.6

Answer:

So, it will take between 4 and 5 bags of quickrete to fill the tube.

Step-by-step explanation:

To find the volume of the sonotube, you can use the formula for the volume of a cylinder: V = πr^2h, where r is the radius of the tube and h is the height.

First, you need to find the radius of the tube. The diameter of the tube is 10 inches, so you can divide that by 2 to get the radius: r = 10 inches / 2 = 5 inches.

Then, you can plug the radius and height into the formula to find the volume of the tube: V = πr^2h = π(5 inches)^2(48 inches) = about 235.61 inches^3.

To find the number of bags of quickrete you will need to fill the tube, you need to convert the volume of the tube to cubic feet and then divide by the number of cubic feet in a bag of quickrete.

First, you can convert the volume of the tube to cubic feet by dividing by 1728 (the number of cubic inches in a cubic foot): V = 235.61 inches^3 / 1728 inches^3/ft = about 0.14 cubic feet.

Then, you can divide this volume by the number of cubic feet in a bag of quickrete to find the number of bags you need: 0.14 cubic feet / (1 cubic foot / 30-40 bags) = about 4-5 bags.

So, it will take between 4 and 5 bags of quickrete to fill the tube.

The circumcenter of a triangle formed by (4,2), (3,-3) and (2,2) is located at (3, -0.4).

The circumcenter of a triangle is the point of intersection of the three perpendicular bisectors of the sides of a triangle.

Let A = vertex at (4,2)

B = vertex at (3,-3)

C = vertex at (2,2)

Get the midpoint of each side.

midpoint = [(x₂ + x₁)/2 , (y₂ + y₁)/2]

side AB : midpoint = [(3 + 4)/2 , (-3 + 2)/2] = (3.5, -0.5)

side AC : midpoint = [(4 + 2)/2 , (2 + 2)/2] = (3, 2)

side BC : midpoint = [(3 + 2)/2 , (-3 + 2)/2] = (2.5, -0.5)

Get the slope of each side.

slope = (y₂ - y₁) / (x₂ - x₁)

side AB : slope = (-3 - 2) / (3 - 4) = 5

side AC : slope = (2 - 2) / (2 - 4) = 0/-2 = 0

side BC : slope = (2 - -3) / (2 - 3) = -5

Determine the equation of the line of each of the three perpendicular bisectors of the sides of a triangle, that passes through the midpoint and with a slope equal to the negative reciprocal of the slope of the side.

y = mx + b

perpendicular bisector of AB :

-0.5 = -1/5(3.5) + b   ;   b = 0.2   ;   y = -1/5x + 0.2

perpendicular bisector of AC :

since AC is a horizontal line, x = 3

perpendicular bisector of BC :

-0.5 = 1/5(2.5) + b   ;   b = -1   ;   y = 1/5x - 1

Since x is already equal to 3, substitute the value of x in the two other equation and solve for y.

y = -1/5x + 0.2

y = -1/5(3) + 0.2

y = -0.4

y = 1/5x - 1

y = 1/5(3) - 1

The values of x and y after solving this system of equations will be 32/35 and -88/105 respectively.

System of equations are a set of two or more equations that contain variables. The values of the variables can be calculated using either method of elimination or substitution. The values of the variables must then satisfy all the equations.

For a set of two equations, in elimination we make the coefficient of any one variable equal to the coefficient of the same variable in the other equation. This can be done by multiplying or dividing the whole equation accordingly. Then we subtract the equations from each other and solve for one variable.

6x - 3y = 8 (multiplying this equation by -2 to make the coefficient of y equal to that of in the equation 23x + 6y = 16)

Now are equations are

-12x + 6y = -16 and 23x + 6y = 16

subtracting eq 1 from eq 2 gives,

35x = 32 (Note that y has now been eliminated)

After 3 seconds will it take for it to fall 112 feet.

What is distance?

Distance is a measurement of how far apart two objects or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

Given:

The distance s that an object falls varies directly with the square of the time, t , of the fall.

⇒ D = KT^2

Where D is the distance

T is the time

K is the proportionality constant

As an object falls 16 feet in one second.

⇒  D = 16, T = 1

⇒ 16 = K(1)^2

   16 = K

Therefore, the equation becomes

D = 16T^2

To find the how long will it take for it to fall 112 feet.

Here D = 112 feet

Plug D = 112 in the above equation.

112 = 16T^2

The area of the rhombus inside a square formed by two equilateral triangles is 1.856 cm².

Here we have to find the area of the rhombus.

Data given:

sides of a square = 2√3 cm

Let ABCD be a square whose sides are 2√3 cm.

As two triangles are inscribed in a square so ABE and CDG be equilateral triangles in square ABCD.

The altitude of the equilateral triangle ABE and CDE = 2√3 sin 60°

= 2√3 × √3/2

= 3cm

The diagonal EG of the rhombus EFGH = 2√3 - 2(2√3 - 3)

= 2.535 cm

The diagonal FH of the rhombus, EFGH = 2√3 - 2(√3tan 30°)

= 1.464 cm

The formula for the area of the rhombus = d1 × d2 / 2

where d1 and d2= diagonal of a rhombus

Now the area of the rhombus EFGH = EG × FH / 2

= 2.535 × 1.464 / 2

The best course grade your friend can earn is 73.8% the minimum score would your friend would need on the final to earn a 75% for the course is 108%.

Given that,

Before the course's final exam, a friend had an 84% course average. Except for the final, which accounts for 15% of the course grade, everything else is included in that score.

We have to find what is your friend's best possible course grade and What grade on the final must your friend obtain in order to receive a 75% for the course.

We know that,

Best grade = (84%)(0.7) + (100%)(0.15)

Best grade=0.588+0.15

Best grade=0.738 or 73.8%

Now,

Let final = 15% of the grade

Let class work = (110%-15%)=95%

Let your friend minimum score =f

So,

70%(0.84) + 15%(final) = 75%

0.7(0.84) + 0.15f = 0.75

0.588 + 0.15f = 0.75

Collect like terms

0.15f=0.75-0.588

0.15f = 0.162

Divide both side by 0.15f

f=0.162/0.15

f =1.08 or 108%

Therefore, the best course grade your friend can earn is 73.8% the minimum score would your friend would need on the final to earn a 75% for the course is 108%.
