A telephone pole is 54 feet tall. A guy wire runs 83 feet, from point A at the top of the telephone pole, to the ground at point B. The base of the telephone pole is at point C. Triangle ABC is a right triangle.
How far from the base of the telephone pole, to the nearest tenth of a foot, is the guy wire secured to the ground at point B?
Okay, let's break this down step-by-step:
* The telephone pole is 54 feet tall
* The guy wire runs 83 feet from point A (top of pole) to point B (ground)
* So the hypotenuse (AB) of the right triangle is 83 feet
* The opposite side (AC) is 54 feet (height of pole)
To find the adjacent side (BC), we use the Pythagorean theorem:
a^2 + b^2 = c^2
54^2 + BC^2 = 83^2
Solving for BC gives:
BC = sqrt(83^2 - 54^2) = sqrt(1296 - 2916) = sqrt(1620) = 40 feet
So the guy wire is secured 40 feet from the base of the telephone pole.
Rounded to the nearest tenth is 40.0 feet.
Therefore, the final answer is:
40.0

The first four terms of the sequence t/n = n(6n - 2) are: 4, 20, 48, 88.
How to find st four terms of the sequenceLet's substitute n = 1:
t/1 = 1(6(1) - 2)
t = 1(6 - 2)
t = 4
The first term of the sequence (when n = 1) is 4.
Now, let's substitute n = 2:
t/2 = 2(6(2) - 2)
t = 2(12 - 2)
t = 2(10)
t = 20
The second term of the sequence (when n = 2) is 20.
Next, let's substitute n = 3:
t/3 = 3(6(3) - 2)
t = 3(18 - 2)
t = 3(16)
t = 48
The third term of the sequence (when n = 3) is 48.
Lastly, let's substitute n = 4:
t/4 = 4(6(4) - 2)
t = 4(24 - 2)
t = 4(22)
t = 88
The fourth term of the sequence (when n = 4) is 88.
Therefore, the first four terms of the sequence t/n = n(6n - 2) are: 4, 20, 48, 88.

B. (x, y) ⟶ (–0.5x, 0.5y)
C. (x, y) ⟶ (2x, 2y)
D. (x, y) ⟶ (–2x, 2y)
Based on the analysis, the correct transformation that maps triangle △UVW to triangle △EFG is option C: (x, y) ⟶ (2x, 2y), which represents an enlargement or dilation of the figure.
To determine which transformation maps triangle △UVW to triangle △EFG, we need to analyze the given options and understand the effects of each transformation.
A. (x, y) ⟶ (0.5x, 0.5y):
This transformation scales the coordinates of a point by a factor of 0.5 in both the x and y directions.
It represents a reduction or contraction of the figure.
Triangle △UVW would be scaled down to a smaller size, so option A is not the correct transformation.
B. (x, y) ⟶ (–0.5x, 0.5y):
This transformation reflects the coordinates of a point across the y-axis and scales the x-coordinate by a factor of -0.5 and the y-coordinate by a factor of 0.5.
It represents a reflection and scaling.
Triangle △UVW would be reflected across the y-axis and scaled, which does not match the transformation to △EFG.
Therefore, option B is not the correct transformation.
C. (x, y) ⟶ (2x, 2y): This transformation scales the coordinates of a point by a factor of 2 in both the x and y directions.
It represents an enlargement or dilation of the figure.
Triangle △UVW would be scaled up to a larger size, which aligns with the transformation to △EFG.
Therefore, option C could be the correct transformation.
D. (x, y) ⟶ (–2x, 2y):
This transformation reflects the coordinates of a point across the x-axis and scales the x-coordinate by a factor of -2 and the y-coordinate by a factor of 2.
It represents a reflection and scaling.
Triangle △UVW would be reflected across the x-axis and scaled, which does not match the transformation to △EFG.

How to obtain the measure of angle ABC?First we look to the exterior angle of angle C in the bottom parallel line, as a ray is formed, hence the missing angle measure is given as follows:
50 + 75 + x = 180
125 + x = 180
x = 55º.
The exterior angle relative to angle B is supplementary with the angle of 55º, as they are consecutive angles, hence it’s measure is obtained as follows:
y + 55º = 180
y = 125º.
By the exterior angle theorem, an interior angle is supplementary with it’s respective exterior angle, hence the measure of angle ABC is given as follows:

A popular brand has introduced a new design of jeans. All major stores have stocked the jeans because the brand usually sells very well. But the cost of these jeans is much higher than those of other brands, so people don't buy them.
The price of the jeans will decrease because supply is greater than demand hence the stores will sell them at discounted prices.
How do we calculate?The store owners would be forced to cut pricing if the jeans weren't purchased at all or as frequently as the other brands. Either they choose that choice, return the goods if possible or just toss the jeans away. It generally takes some trial and error to determine the proper price.
For instance, the owner may lower the price to $75 and test whether the 25% discount works or not if the jeans initially sell for $100 and nobody buys them for a week.
The price might remain there if people continue to buy and if not, the cost might decrease even further.

how much money deposited now will provide payment of Rs. 15000 at the end of each half year for 10 years, if interest is 16% compounded six-monthly
The amount of money that will produce Rs. 15000 at the end of 6 month for 10years at 16% is Rs. 3750
What is Compound interest?Compound interest is the interest you earn on interest.
For example, if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.
Compound interest is expressed as;
A = P( 1+r/n) ^{nt}
where A is the amount
n is the number of time its compounded
t is time
A = 15000
r = 16/100 = 0.16
n = 6/12 = 0.5
t = 10 years
15000 = P( 1 + 0.16/0.5) ^{ 0.5× 10}
15000 = P( 1 + 0.32)⁵
15000 = P( 1.32)⁵
15000 = 4P
P = 15000/4
P = Rs. 3750

Step-by-step explanation:
limit for n going to what ?
I think you mean n going to ±infinity.
for very large n (when n goes to infinity) such a fraction is reduced to the ratio of the terms with the highest exponents of n. the terms with lower exponents simply get less and less impact with growing n, and fade away for really, really large n going to infinity.
so, this limit evaluation is reduced to
lim n²/(3n³ + n²) = 1/(3n + 1)
which is again for very large n
lim 1/(3n), which goes to 1/infinity = 0
the same for going to 1/-infinity = 0
if you meant e.g. limit for n going to 0, then for the limit we set n to 0 and see, that all terms are turning 0, except for the constants -5 in the numerator and +7 in the denominator.
so, that limit is then

Submit
The length of the hypotenuse of the given right triangle is 117 millimeters because it is the longest side and it satisfies the conditions of the Pythagorean theorem.
The length of the hypotenuse of a right triangle with side lengths 45 millimeters, 108 millimeters, and 117 millimeters is 117 millimeters.
The hypotenuse of a right triangle is always the side opposite the right angle, and it is the longest side in a right triangle.
In this case, the side lengths are given as 45 millimeters, 108 millimeters, and 117 millimeters.
By comparing the lengths, we can see that 117 millimeters is the longest side, which makes it the hypotenuse.
To further understand why the hypotenuse is the longest side, we can refer to the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
Mathematically, it can be written as c² = a² + b²,
where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides.
In this case, if we square the lengths of the sides, we get 45² = 2025, 108² = 11664, and 117² = 13689.
By comparing these values, we can see that 13689 is the largest, which corresponds to the length of the hypotenuse, 117 millimeters.

i need some help here
The value of x, considering the Pythagorean Theorem, is given as follows:
x = 9.
What is the Pythagorean Theorem?The Pythagorean Theorem states that in the case of a right triangle, the square of the length of the hypotenuse, which is the longest side, is equals to the sum of the squares of the lengths of the other two sides.
Hence the equation for the theorem is given as follows:
c² = a² + b².
In which:
c > a and c > b is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.The sides for the problem are given as follows:
15 and 8 (segment of 8 is the radius, which is the distance from the center to a point on the circumference of the circle).
Hence the hypotenuse is obtained as follows:
h² = 15² + 8²
h² = 289
h = 17.
Hence the value of x is obtained as follows:
x = 17 - 8
x = 9.

Find the sum below. Explain how you got this answer
-11 + 3 + 10 + (-25) + 48 =
Answer:
25
Step-by-step explanation:
There are only additions, so do each addition, in the order it appears, from left to right.
-11 + 3 + 10 + (-25) + 48 =
= -8 + 10 + (-25) + 48
= 2 + (-25) + 48
= -23 + 48
= 25
