How many litres can be held by a cylindrical can 14cm in diameter and 20cm hight?
Answer:
about 3.08 L
Step-by-step explanation:
You want the number of litres in the volume of a cylindrical can 14 cm in diameter and 20 cm high.
LitersA litre is a cubic decimeter, 1000 cubic centimeters. As such, it is convenient to perform the volume calculation using the dimensions in decimeters:
14 cm = 1.4 dm . . . . . . diameter20 cm = 2.0 dm . . . . . heightVolumeThe volume of the cylinder is given by the formula ...
V = (π/4)d²h . . . . . . . where d is the diameter and h is the height
V = (π/4)(1.4 dm)²(2.0 dm) ≈ 3.079 dm³ ≈ 3.08 L
The cylindrical can will hold about 3.08 litres.

what is the graph of linear inequality 2y>x-2
Answer:
Please refer to the attached graph for the graph of linear inequality:
\(2y>x-2\)
Step-by-step explanation:
Method to draw graph of inequality:
1. First of all replace the inequality sign with equality.
Now the equation is:
\(2y=x-2\)
Now, find point and plot them.
Let us put x = 0, we get y = -1. So one point is (0, -1)
Let us put y = 0, we get x = 2. So one point is (2,0)
Now, plot both the point and join with straight line on xy coordinate axis.
2. Now, try to find a random point and put in the inequality.
If the point satisfies the inequality shade the region moving from the line towards that point.
For example:
Taking a point (4, 2)
Putting in the inequality:
\(8 > 2-2 \\8>0\)
So, (4, 2) satisfies the inequality.
Now, shade the region moving from the line towards the point (4,2).
We get the shaded region as shown in the attached figure in the answer area.
Inequalities are used to represent expressions of unequal values
The linear inequality is given as:
\(2y > x - 2\)
Divide through by 2
\(y > 0.5x - 1\)
The above linear inequality means that:
The inequality has a dotted lineThe upper part is shadedThe slope of the line is 0.5The y-intercept is -1See attachment for the graph of \(2y > x - 2\)

Ratna wants to pave stone in his triangular yard of sides 50m, 50m and 60m. If the area of each stone is 120cm², find the total number of stones required for it. Also, calculate the total cost at the rate of Rs. 5 per stone
The total number of stones required to pave the yard would be 100,000√3 stones and the cost would be Rs. 500000√3 at the rate of Rs. 5 per stone.
Rate calculationTo find the number of stones required, we need to find the area of the triangular yard and then divide it by the area of each stone.
First, let's find the area of the triangular yard using Heron's formula:
s = (50 + 50 + 60) / 2 = 80
Area = √(s(s-50)(s-50)(s-60)) = √(803030*20) = 1200√3 m²
Now, we need to convert the area to cm² and divide by the area of each stone:
Area in cm² = (1200√3) * 10000 = 12000000√3 cm²
Number of stones required = (Area in cm²) / (Area of each stone) = (12000000√3) / 120 = 100000√3 stones
Finally, to calculate the total cost at the rate of Rs. 5 per stone, we simply multiply the number of stones by the rate per stone:
Total cost = (100000√3) * Rs. 5 = Rs. 500000√3

Answer:
83/10
Step-by-step explanation:
let x represent the number:
43/10 - x = 4
x = 4 + 43/10
simplifying the answer:
x = (4(10) + 43)/10
x = (40 + 43)/10
x = 83/10

One positive point charge q1 is located at (x, y) coordinate (-4. 37, -7. 77) and a second positive point charge q2
The value of positive point charge q1 would have to be \(2.65*10^{-8}\) C to make the x-component of the electric force exerted by q1 on q2 equal to 0.289 N.
The electric force between two point charge q1 and q2 is given by Coulomb's law:
F = \(k*q1*q2/r^{2}\)
Where k is the Coulomb constant \((8.99*10^{9}Nm^{2}/C^{2} )\), q1 and q2 are the charges, and r is the distance between the charges. The x-component of the electric force can be found by considering only the x-component of the separation between the charges:
Fx = F * (x2 - x1) / r
Where x1 and x2 are the x-coordinates of the charges, and r is the distance between the charges.
We are given that q2 = 1E-5 C, and we want to find the value of q1 such that Fx = 0.289 N. To do this, we need to find the x-component of the separation between the charges and the distance between the charges.
First, the x-component of the separation between the charges is:
(x2 - x1) = (4.89 - (-4.37)) = 9.26 m
Next, the distance between the charges is given by the Pythagorean theorem:
r = \(\sqrt{(x^{2} -x1)^{2}+(y2-y1)^{2} }\) = \(\sqrt{9.26^{2} + (7.54-(-7.77)^{2} )}\) = 15.15 m
Now we can use the above equations to find the value of q1:
0.289 = \(k*q1*(1E-5)/15.15^{2}\)
q1 = \(0.289/(k * (1E-5)/15.15^{2} )\)
q1 = \(0.289/(8.99*10^{9} * 1E-5/15.15^{2} )\)
q1 = \(0.289/(8.99*10^{9} * 1E-5/227.3 )\)
q1 = \(2.65 * 10^{-8}\) C
So the value of q1 would have to be \(2.65 * 10^{-8}\) C in order to make the x-component of the electric force exerted by q1 on q2 equal to 0.289 N.

a famer has 120 feet of fencing with whcih to enclose two adjacent rectangular pens as shown. what dimeensions should be used that the enclosed area will be a maximum? what will the area be?
The dimensions of the rectangular pen should be 15 by 20 feet and the maximum area is 1200 square feet.
Let the area be y .
Area = (base) × (height)
Base = 2x
Height = h
Let the area of the rectangular pens be y .
∴ y = 2xh
Perimeter of all the fencing = 4x+3h
∴ 4x+3h = 120
now we solve for h
3h = 120-4x
h = 40 - 4/3 x
Now we will substitute this value in the above first equation:
y = 2xh
or, y = 2x (40 - 4/3 x)
or, y = 80x - 8/3 x²
Now for the maximum area we have to find the first order differentiation of y
now,
dy /dx = 80 - 16/3 x
At dy/dx = 0 we get the value of x for which y is maximum.
80 - 16/3 x = 0
or, - 16/3 x = -80
or, x = 15 feet
Hence height = 40 - 4/3 x = 40 - 20 = 20feet
Maximum area = 2xh = 2×15×40 = 1200 square feet
The dimensions of the rectangular pen should be 15 by 20 feet and the maximum area is 1200 square feet.

By the assumption of collinearity between points A, B and C and line segment properties, the length of the line segment BC is 7.
What is the length of a missing line segment?
According to Euclidean geometry, a line is generated by two distinct points set on a plane and three points are collinear if they lie on one and same line. Algebraically speaking, we know that that line segments are contained in the following model:
AC = AB + BC
AC = AB + BC (1)
If we know that AC = 19 and AB = 12, then the length of the line segment BC is:
19 = 12 + BC
BC = 19 - 12
BC = 7

For the function, find the points on the graph at which the tangent line is horizontal. If none exist, state that fact.
The points on the graph at which the tangent line is horizontal are:
(-1.414, 4.886) and (1.414, 1.114).
What is the horizontal point on the tangent line?
Since the horizontal tangent is parallel to the x-axis, its slope, or derivative, should also have a value of 0 at the tangent point. This is the key concept for finding the point on the graph where the tangent line is horizontal.
The function is given as:
y = ¹/₃x³ - 2x + 3
The tangents are horizontal where the derivative is zero. The derivative of the given function is:
y' = x² -2
This is zero when:
0 = x² -2

x = ±√2 . . . x-values where the derivative is zero
The corresponding y-values are:

To find the points on the graph at which the tangent line is horizontal, we need to find the x-values where the derivative of the function is equal to zero.
To find the points on the graph at which the tangent line is horizontal, we need to find the x-values where the derivative of the function is equal to zero. The derivative represents the rate of change or slope of the function at any given point.
Let's say we have a function f(x). To find the derivative of f(x), we differentiate the function with respect to x. The resulting derivative function is denoted as f'(x) or dy/dx.
Next, we set the derivative function f'(x) equal to zero and solve for x. The x-values obtained from this equation represent the points on the graph where the tangent line is horizontal.
If there are no solutions to the equation f'(x) = 0, it means there are no points on the graph where the tangent line is horizontal.

Find the sum of squares due to regression, if the sum of squares due to error is 6972.20 and the total sum of squares is 15846.95 . Round your answer to 2 decimals.
The sum of squares due to regression is approximately 8862.75.
The sum of squares due to regression (SSR) can be calculated using the formula:
SSR = SST - SSE
where SST is the total sum of squares and SSE is the sum of squares due to error.
Given that the sum of squares due to error is 6972.20 and the total sum of squares is 15846.95, we can substitute these values into the formula to find SSR:
