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

Answer:

The answer is "Experimental Probability  ".

Step-by-step explanation:

The probability of experiments is uncertainty which is calculated several times as per the outcome of even an experiment. The probability distribution is probably dependent upon reasoning. This probability is a price of about one or zero. It was based on the relative frequency or what occurs during a probability test.

Step-by-step explanation:

tan 45=1/1=1

Tan Theta is one of the trigonometric ratios which is equal to opposite / Adjacent in a triangle, the value of tan45 is 1.

The 45-45-90 triangle is also an isosceles triangle, which means its two legs are equal in length.

Tan Theta is one of the trigonometric ratios which is equal to opposite / Adjacent in a triangle.

The side lengths of a 45-45-90 triangle are in the ratio 1: 1: [tex]\sqrt{2}[/tex].

The value of tan45 is given by the following formula;

[tex]\rm Tan 45 = \dfrac{Perpendicular}{Base}\\\\Tan45=\dfrac{1}{1}\\\\Tan45=1[/tex]

Hence, the value of tan45 is 1.

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:

AC ≈ 5.5

Step-by-step explanation:

Angle bisector theorem states that "angle bisector of an angle divides the opposite side into two segments which are proportional to the other two sides of the triangle."

By applying this theorem in the given ΔABC,

AD is the angle bisector of ∠CAB which divides the opposite side of the angle into two segments BD and CD.

Therefore, [tex]\frac{AB}{BD}=\frac{AC}{CD}[/tex]

[tex]\frac{5.1}{4}=\frac{AC}{4.3}[/tex]

[tex]AC=\frac{5.1\times 4.3}{4}[/tex]

AC = 5.4825

AC ≈ 5.5 units

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.
