Which basic geometric term has exactly one dimension?

Degger [83]

Answer: Option 'C' is correct.

Step-by-step explanation:

We need to find which has one dimension.

Since Point is undefined term with no size or dimension, but in two dimensional it is found in ordered pair i.e. (x,y)

Plane is also an undefined term with length and width but no thickness, so, it is two dimensional.

Angle is undefined term formed by tow lines or rays diverging from a common vertex, so it is two-dimensional.

But Line is also undefined term with length only but there is no width or thickness.

So, Line has exactly one dimension.

Hence, Option 'C' is correct.

At the district competition for 5th grade jump-roper of the year, the following number of jumps without stopping were recorded p

Tcecarenko [31]

Answer:

Mean = 242.83

Median = 265

Step-by-step explanation:

Looking at the data set, we see there are "24" numbers.

The mean is the average, which is sum of all the numbers divided by the number of numbers.

The median is the middle value when the numbers are arranged in ascending order. Since there are even number of numbers (24), the median would be the average of 12th number and 13th number.

First, lets arrange the numbers in ascending order:

90, 100, 100, 200, 203, 224, 233, 237, 245, 257, 264, 265, 265, 266, 277, 279, 285, 288, 290, 290, 291, 291, 300

The mean is the sum of all of them divided by 24:

Mean = 242.83

The median is the average of 12th number (265) and 13th number (265). So that is:

(265+265)/2 = 265

Thus,

Mean = 242.83

Median = 265

Which of the following functions are solutions of the differential equation y" – 4y' + 3y = 0? CA. y(x) = xe-3x B. y(x) = et C.

Kipish [7]

Answer:

$y(x)=c_1e^{x}+c_2e^{3x}$

$y(x)=e^x$

$y(x)=e^{3x}$

Option B is correct. $y=e^t$

Step-by-step explanation:

Given: y''-4y'+3y = 0

It is a linear differential equation.

First we make characteristic equation.

$m^2-4m+3=0$

Now factor the equation and we get

$(m-3)(m-1)$

$m=1,3$

Here, we have two distinct root.

$y(x)=c_1e^{m_1t}+c_2e^{m_2t}$

Solution of differential equation:

$y(x)=c_1e^{x}+c_2e^{3x}$

where, c₁ and c₂ are constants.

Hence, The solution of the given differential equation is $y(x)=c_1e^{x}+c_2e^{3x}$

$y(x)=e^x$

$y(x)=e^{3x}$
