Two poles of lengths 10ft and 15ft are set up vertically with their bases on horizontal ground 12ft apart. Find the distance between the tops of the poles
By using the concept of Pythagoras Theorem, the result obtained is
Distance between their tops is 13 ft.
What is Pythagoras Theorem?
Pythagoras Theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of perpendicular and base.

Let the poles be represented by CD and AE and let AC represents the distance between their tops
Construction
A line from C parallel to DE (shown by a dotted line) is drawn
CD = 10 ft.
AE = 15 ft.
BE = 10 ft.
AB = AE - BE
= 15 - 10

what is the smallest positive integer that can be expressed as the sum of nine consecutive integers, the sum of ten consecutive integers, and the sum of eleven consecutive integers? (1993,
Any positive integer n that meets the three requirements is a multiple of 9 and 11, as well as an odd multiple of 5. Lcm(5,9,11)=5911=495 is the smallest such n.
What is integer?Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers.
Here,
The n subsequent integers from -(n-1)/2 to (n+1)/2 have a sum of 0 if n is an odd number. Sum n is produced by translating the interval to the right by 1. Each positive sum is therefore a positive multiple of n.
If n is even, the sum of the next n even integers from -n/2-1 to +n/2 is n/2. Sum n+n/2 is produced by moving the interval to the right by 1. As a result, every positive sum is an odd multiple of n/2.
Therefore, any positive integer n that meets the three requirements is a multiple of 9 and 11, as well as an odd multiple of 5. Lcm(5,9,11)=5911=495 is the smallest such n.

1. A = 45° B = 110°
2. B = 88° C = 44°
3. A = 59° B = 48° C= 73°
4. The measure of the exterior angle is 108°
5. The tornado's direction needs to change by 30°
The sum of interior angles of triangle is always equal to 180°.
Now let's apply it in the given questions.
1. A = x
B = x + 65
C = 25
So, x + x + 65 + 25 = 180
2x = 180 - 90
x = 90/2
x = 45°
2. x + 48 + x - 44 = 180
2x = 180 - 4
x = 176/2
x = 88°
3. x + 73 + x - 11 = 180
2x = 180 - 62
x = 118/2
x = 59°
4. Let the third interior angle be b.
2a + b = 180
b = 180 - 2a
now by applying angle sum property
a + 10 + 44 + 180 - 2a = 180
2a - a = 54
a = 54°
the exterior angle is 2a that is 54*2 = 108°
5. For the tornado to deviate and pass through radar station instead of cell phone tower the angle that needs to be made will be nothing but the third interior angle of the triangle as the tornado is at the vertex.
Let us suppose the angle to be y
so y + 75 + 75 = 180

C. The angles are given as follows:
m < 1: 57º.m < 2: 57º.m < 3: 123º.How to obtain the mesures?The two parallel lines, p and q, are cut by the transversal line, hence angles 2 and 3 are supplementary angles, and thus:
x - 9y + 1 + 11x + 2 = 180
12x - 9y = 177.
Angles 1 and 2 are alternate interior angles, meaning that they are congruent, hence:
6x + y - 4 = x - 9y + 1.
5x + 10y = 5.
x + 2y = 1.
x = 1 - 2y.
Replacing in the first equation, the value of y is given by:

The line x + 2y = 16 is perpendicular to a line containing the points (-9,n) and (1,5n). Find the value of n.
So how do I do it?
Step #1: Find the slope of the given line.
To do this, solve the equation for slope-intercept form:
x + 2y = 16
2y = -x + 16
y = -1/2 x +8
The slope of this line is -1/2.
Step #2: Find the slope of the new line.
To be perpendicular, the other line needs a slope that is the opposite reciprocal slope. So, that'd be +2/1 or just 2.
Step #3: Find n.
Now, you know m=2 and we also have the slope formula
m = (y2 - y1) / (x2 - x1)
Using the two points (-9,n) and (1,5n), we can set up:
2 = (5n - n) / (1 - (-9))
2 = 4n / 10
2 = 2n/5
Multiply by 5 and divide by 2:
10 = 2n
5 = n
The process was: find the slope of the given line, use that to find the slope of the perpendicular line, and then use and the slope formula to find n.

Given that a line has a y-intercept of 3 and an x-intercept of 4, write an equation for the line.
Given that a line has a y-intercept of 3 and an x-intercept of 4
The equation of the line is 4y−12=3x.
The line has an x-intercept at x=−4 and y intercept at y=3, this means that the line passes through the points (−4,0) and (0,3).
Now we find the slope m of the line passing through the points (−4,0) and (0,3) (x-intercept).
The slope of the line is:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{3-0}{0-(-4)} = \frac{3}{4}[/tex]
Point-Slope Formula:

describe how the time of flight range and maxium height would change if the angle was shot out at originally were change to 55 degrees
Increasing the launch angle increases the maximum height. Increasing the launch angle increases the time of flight.
The starting vertical velocity determines the time in the air. Increasing the launch angle lengthens the duration in the air because steeper launch angles have a larger vertical velocity component.
The height of release and the angle of release is related. -The angle of release decreases as release height increases. - The angle of release rises as the height of release falls.
We observe that the projectile's maximum height is dependent on both initial speed and the angle of projection (), just as it is in the case of flight time. The projectile will rise to a larger height if its initial velocity is higher and its angle of projection from the horizontal is greater.

use the delta method to approximate the standard error for the square root of the sample average g
To use the delta method to approximate the standard error for the square root of the sample average g, we first need to calculate the sample average g.
What is an error?A variation from precision or correctness is called an error. An error, then, is a mistake or a failure to perform an action appropriately. Errors can take place person commits a calculation error, an equipment breaks down, or a person interprets information incorrectly.
Various factors might lead to errors. For instance, a person may make a mathematical error because they misunderstood the problem or made an error when doing the computation. A machine may break down due to a design error, normal wear and tear, or an outside event like a power loss. A person's prejudice may cause them to interpret information incorrectly.
How to solve?
This can be done by summing all the values in the sample and dividing by the total number of values in the sample. Next, we need to find the derivative of the function that describes the square root of the sample average g. This derivative will be used to approximate the standard error. To find the standard error, we then multiply the derivative by the standard deviation of the sample average g. This will give us an approximation of the standard error for the square root of the sample average g. It is important to note that this approximation will only be accurate if the sample is normally distributed and the sample size is large. Additionally, the delta method is only one way to approximate the standard error, and other methods may be more appropriate in certain situations.
