The length of the fence must be 618cm

The volume that it can hold is 1,909,620 cm³

First, the fence is just equal to the circumference of the cylinder, remember that the circumfernce of a circle of diameter D is:

C = П*D

Here we use П = 3, then:

C = П*206cm

C = 3*206cm = 618cm

Now the volume, for a cylinder of diameter D and height H, the volume is:

V = П*(D/2)²*H

Replacing the values that we know we will get:

V = 3*(206cm/2)²*60cm = 1,909,620 cm³

The slope of the straight line passing through the two given points is undefined which means the line is parallel to the y-axis.

Let us consider the two points A(x₁,y₁) and B(x₂,y₂) be the two points (7,-6) and (6,-6) on the cartesian coordinates.

Let the slope of the line joining A (7,-6)  and B(6,-6)  be m.

We know that the slope of a line is given by:

\(m=\frac{y_2-y_1}{x_2-x_1}\)

Slope of the line

= (6-7) / (-6+6)

= -1 / 0

= undefined

Since the slope is undefined we can say that the straight line is parallel to the y axis.

we know that tan 90° = ∞

So any line parallel to this line will have the same slope as the y axis.

Hence the slope of the given line is undefined or infinity.

Domain of the function represented by the graph of a quadratic function y = \(x^2\) – 4 with a minimum value at the point (0,-4) is all real numbers.

The correct answer is option D.

To determine the domain of the quadratic function y = \(x^2\) - 4, we need to consider the x-values for which the function is defined. Since a quadratic function is defined for all real numbers, the domain of this function is "all real numbers."

Let's analyze the given function and its graph to understand why the domain is "all real numbers."

The function y =  \(x^2\) - 4 represents a parabola that opens upward, which means it extends infinitely in both positive and negative x-directions. The vertex of the parabola is at the point (0, -4), indicating that the minimum value of the function occurs at x = 0.

Since there are no restrictions or limitations on the x-values for which the function is defined, the domain is unrestricted and encompasses all real numbers. In other words, the function can be evaluated and calculated for any real value of x, whether it is a negative number, zero, or a positive number.

Option B : The center of a triangle's inscribed circle.

Draw the triangle and circle and lines form the center of the circle to the point where the sides of the triangle are tangent to the circle.

Final answer:

Option B : The center of a triangle's inscribed circle.

I. A statement p(10n) = p(n) is not true for each positive integer n.

II. A statement p(n+1) > p(n) is not true for each positive integer n.

III.A statement p(2n) = 2p(n) is not true for each positive integer n.

The correct answer is an option (A)

Here, p(n) is defined to be the product of the digits of n

Consider the first statement.

p(10n) = p(n)

p(10n) will always have units digit as 0

p(n) can be any integer.

⇒ p(10n) ≠ p(n)

Thus, the first statement must not be true.

Consider statement - II

p(n + 1) > p(n)

for n = 2

p(n +1) = 3 and p(n) = 2

i.e., p(n + 1) > p(n)

for n = 9;

p(n + 1) = 0 and p(n) = 9

i.e., p(n + 1) < p(n)

Thus, the second statement must not be true.

Consider the statement - III

p(2n) = 2 × p(n)

for n = 12;

p(2n) = p(2 × 12)

        = p(24)

        = 8

And 2 × p(n) = 2 × p(12)

                    = 2 × 2

                    = 4

This means that p(2n) ≠ 2 × p(n)

Thus, the third statement must not be true.

Answer

The y-intercept = 2

Explanation

The slope and y-intercept form of the equation of a straight line is given as

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

So, we just have to write the given equation in this form and the y-intercept will become apparent.

x + 4y = 8

4y = -x + 8

Divide through by 4

(4y/4) = (-x/4) + (8/4)

y = -0.25x + 2

Comparing this with y = mx + b

We can see that

b = y-intercept = 2

All you have to do is multiply 19.8 x 26

We will use sine function, and length of the opposite side is \(\frac{25\sqrt{3}}{2}$\) feet.

To solve for the opposite side of the right triangle, we would use the sine function. In a right triangle, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse.

In this problem, we are given that one angle of the right triangle is 60 degrees and the hypotenuse is 25 feet. Let's label the opposite side as x and the adjacent side as y. Then we can use the sine function:

\($\sin 60^\circ = \frac{x}{25}$\)

Simplifying the left side, we have:

\($\frac{\sqrt{3}}{2} = \frac{x}{25}$\)

Multiplying both sides by 25, we get:

\($x = \frac{25\sqrt{3}}{2}$\)

Therefore, the length of the opposite side is \(\frac{25\sqrt{3}}{2}$\) feet.

1.1. Accumulated depreciation:

The accumulated depreciation for the machine bought on 1 July 2013 would be R150,000 as of 31 March 2016.

1.2. Machine realization:

The machine bought in 2013 was sold for R120,000 on 30 June 2015, resulting in a profit/loss on the sale of R10,000.

1.1. Accumulated Depreciation:

To calculate the accumulated depreciation, we need to determine the annual depreciation expense for each machine and then accumulate it over the years.

Machine bought on 1 July 2013:

Cost: R250,000

Depreciation rate: 20% per annum on cost

Depreciation expense for the year ended 31 March 2014: 20% of R250,000 = R50,000

Depreciation expense for the year ended 31 March 2015: 20% of R250,000 = R50,000

Depreciation expense for the year ended 31 March 2016: 20% of R250,000 = R50,000

Accumulated depreciation for the machine bought on 1 July 2013:

As of 31 March 2014: R50,000

As of 31 March 2015: R100,000

As of 31 March 2016: R150,000

1.2. Machine Realisation:

To record the sale of the machine bought in 2013, we need to adjust the machine's value and the accumulated depreciation.

Machine's original cost: R250,000

Accumulated depreciation as of 30 June 2015: R100,000

Net book value as of 30 June 2015:  

R250,000 - R100,000 = R150,000.

On 30 June 2015, the machine was sold for R120,000.

Realisation amount: R120,000

To record the sale:

Debit Cash: R120,000

Debit Accumulated Depreciation: R100,000

Credit Machine: R250,000

Credit Machine Realisation: R120,000

Credit Profit/Loss on Sale of Machine: R10,000 (difference between net book value and realisation amount).
