Answer:

84.4

Step-by-step explanation:

done

Volume of a right circular cone is  84.39 m³

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Given:

height = 12.4 m. base diameter= 5.1 m, radius= 5.1/2 m

Volume of right circular cone= 1/3* π* r²*h

                                                = 1/3*3.14* 2.55*2.55*12.4

                                               = 84.39 m³

Hence, the volume of right circular cone is 84.39 m³

Step-by-step explanation:

hi

The domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as (-∞, ∞) for all x ∈ R.

The domain is the set of all the input values given to a function.

Given is an expression f(x) = 5x - 7, we need to find the domain,

We know that,

The domain of any expression is set to all the real numbers, except where the expression is undefined.

Therefore, the domain is all real numbers.

Also,

The graph of the function will be a straight line without discontinuities.

Hence the domain of f(x) = 5x - 7 is {x | x is a real number} and this can be denoted as (-∞, ∞) for all x ∈ R.

Answer:

Step-by-step explanation:

Answer:

The third one counting from the top.

Step-by-step explanation:

We have the inequality:

(-1/3)*(2x + 1) < 3

The first thing we need to do is isolate x on one side of the inequality.

First we can by -3 in both sides of the inequality, and remember, because we are multiplying by a negative number, the inequality sign changes its direction:

(-3)*(-1/3)*(2x + 1) > 3*(-3)

(2x + 1) > -9

Now we can subtract 1 in both sides:

2*x + 1 - 1 > -9 - 1

2*x > -10

Now we can divide by 2 in both sides:

2*x/2 > -10/2

x > -5

Then we should see a number line such that all the points at the right of -5 are colored.

The correct option is the third one, counting from the top.

Using pythagoras theorem

Answer:

NPV, IRR, payback.

Step-by-step explanation:

The best worst decision technique involves the choice modelling. In terms of the overall usefulness in the capital budgeting decisions,

-- the decision rule that is best is the NPV

-- the decision rule that is worst is payback period

The NPV capital budgeting tool provides accurate results and it also assumes cash flow can be reinvested at a discount rate.

The IRR is the second best budgeting tool where it assumes that the cash flows can be reinvested at IRR.

And the worst is the payback where it does not take into account its time value of the money and so it does not yield the correct as well as accurate results.

Therefore, ranking the rules from best to worst is : NPV, IRR, payback.

Answer:

The current that produces maximum power is 3A

Step-by-step explanation:

Given

[tex]P(c) = 20(c - 3)^2[/tex]

Required [Missing from the question]

The current that produces maximum power

First, we represent the function in standard form

[tex]P(c) = 20(c - 3)^2[/tex]

[tex]P(c) = 20(c - 3)(c - 3)[/tex]

Open bracket

[tex]P(c) = 20(c^2 -6c+ 9)[/tex]

[tex]P(c) = 20c^2 -120c+ 180[/tex]

The maximum value of c is:

[tex]Max(c) = \frac{-b}{2a}[/tex]

Where:

[tex]f(x) = ax^2 + b^2 + c[/tex]

By comparison: [tex]P(c) = 20c^2 -120c+ 180[/tex]

[tex]a = 20[/tex]

[tex]b = -120[/tex]

[tex]c = 180[/tex]

So, we have:

[tex]Max(c) = \frac{-b}{2a}[/tex]

[tex]Max(c) = \frac{-(-120)}{2 * 20}[/tex]

[tex]Max(c) = \frac{120}{40}[/tex]

[tex]Max(c) = 3[/tex]

Answer:

triangular prism

Step-by-step explanation:

Questions :

(a) Determine the total length of the circular portions in terms of

pi. Show the work that leads to your answer.

(b) Determine the total length of wire needed, both circular and

square portions, to the nearest tenth of an inch.

G

(c) Determine the total weight of the ornament to the nearest

gram.

Answer:

12π

53.68 in

96.624g

Step-by-step explanation:

The total length of the circular portion :

Perimeter of circle = Circumference of the circle = 2πr ; r = radius = 2

Size of each circle is 3/4

Number of circles = 4

Number of complete circles :

4 × 3/4 = 3 complete circles

Perimeter of circle:

Number of circles * (2πr)

3 * 2 * π * 2 = 12π

Total wore needed :

Circular + Square

Perimeter of square = 4s

s=side length = 4

Total square 4 * 4 = 16

Perimeter of Square + perimeter of circle

16 + 12π = 16 + (12 * 3.14) = 53.68 in

Total weight of ornament :

1.8 g * perimeter

1.8 * 53.68 = 96.624g

Answer:

800 ÷ 30 = 26.66666666666667 or 26.

Step-by-step explanation:

Answer:

a. d(x) = x

b. yes

Step-by-step explanation:

a. since c(x) = [tex]x^{2}[/tex] + 1

c(d(x)) = (d(x))^2 + 1 (replace x with d(x))

that means d(x) has to be x for c(d(x)) to equal [tex]x^{2}[/tex] + 1

b. for example if you use 2 as x, c(d(x)) will equal 5 since d(x) = 2 and [tex]2^{2}[/tex] + 1 = 5

d(c(x)) will also equal 5 because c(x) = [tex]2^{2}[/tex] + 1 = 5 and d(c(x)) = c(x) = 5

The diver is approximately 276.5 feet away from the boat to the nearest foot.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

We can use the tangent function to solve this problem.

Let x be the distance from the boat to the point directly below the scuba diver on the water's surface.

Then we have:

tan(39°) = x/356

Multiplying both sides by 356, we get:

x = 356 tan(39°)

x = 276.5

Therefore,

The diver is approximately 276.5 feet away from the boat to the nearest foot.
