the following problems.
(i) Find the height of the pole.
(ii)If the other end of the wire touches the grand at Q, 9 m away from the
base to the opposite side of the pole, find the length of the falling wire.
Step by step solution
Answers
The height of the electric pole is 12 m
When an electric wire falls, its one end touches the ground at P, 5 m away from the base of the pole,
base = 5
length of the wire from the top of the pole to the ground is 13 m
Height of the plant can be calculated by pythagoras theorem
h² = p² + b²
13² = p² + 5²
p² = 169 - 25
p = √144
p = 12m
Therefore, the height of the electric pole is 12 m

The measure of the angle ACB is 87°.
What does the term angle mean?Angles produced by two beams are included in the plane that contains the rays. The intersection of two planes may also produce an angle. Dihedral angles are the name given to them. It is also possible to determine the angle between two crossing curves using the angle created by the rays that are perpendicular to each intersecting curve at that point.
An angle can also refer to a measurement of a rotation or an angle. This number represents the length-to-radius ratio of a circular arc.
When two crossing lines in a plane are not perpendicular to one another, Euclid defined a plane angle as the inclination between those intersecting lines.
In triangle ADE and triangle ACB, the triangles are similar.
So,
∠AED/ ∠ABC = ∠DAE/∠CAB
∠AED = ∠ABC
11x-2 = 6x + 13
11x - 6x = 13 + 2
5x = 15
x = 15/5
x = 3
So, the measure of angle ABC is
∠ ABC = 6(3)+13
∠ ABC = 18+13
∠ ABC = 31°
Now, consider triangle ABC, the sum of all angles = 180°
So, 62° + 31° + ∠ACB = 180°
∠ACB + 93° = 180°
∠ACB = 180° - 93°
∠ACB = 87°

gold miners in alaska have found, on average, 12 ounces of gold per 1,000 tons of dirt excavated with a standard deviation of 3 ounces. assume the amount of gold found per 1,000 tons of dirt is normally distributed. if the miners excavated 1,000 tons of dirt, how little gold must they have found such that they find that amount or less only 15% of the time?
Answers
Miners excavated 1000 tons of dirt, and they found 8.892 ounces of gold.
Let X stand for the random variable determining how much gold is discovered for every 1,000 tonnes of dirt dug up. After that, we learn that:
X ~ N (12, 3²)
Let K be the required amount of discovered gold. 15% of the time, less than K worth of gold is discovered. Next, we have:
P (X ≤ K) = 0.15
When we transform this into a typical normal variable, we get:
P [Z ≤ (K - 12) / 3] = 0.15
From the common normal tables, we can deduce:
P (Z ≤ -1.036) = 0.15
Comparing the two equations above, we obtain:
(K - 12) / 3 = -1.036
K = 12 - (1.036 * 3) = 12 - 3.108 = 8.892
As a result, 8.892 ounces of gold are needed.

let the length be x and the width be y
The parameter of the rectangle is given as;

x + y = 1600
y = 1600-x
let the area of the rectangle be A, then
A = x y
A = x(1600-x)
A = 1600x - x^2
finding the maximum derivative of A with respect of x
da/dx = 1600 - 2x
set da/dx to zero,
1600 - 2x = 0
1600 = 2x
x = 1600/2
x =800
substitute the value of x = 800 in to y

Which inequality represents the phrase "nine less than two

Answers
The expression of the inequality is [tex]9 < 2x\le45[/tex]. It can be obtained using the operations of inequality.
What is inequality?
In matmathematics if two numbers are not equal even then there is a relationship. This relationship can be defined by inequality relationship.
According to the pharase, 9 is less than two times a number. Hence, consider the number is x and its two times means 2x. Now, 9 should be less than this number. Hence, 9<2x. Now, again the number 2x is not more than 45. Means, it can be equal to 45. Hence, it will give the expression [tex]2x\le45[/tex].
Now, combine the two expressions as follows:
9<2x
[tex]2x\le45[/tex]
[tex]9 < 2x\le45[/tex]
Hence, the expression of the inequality is [tex]9 < 2x\le45[/tex].

An investor borrows r11500 to buy a computer and is charged interest at an annual rate of 6 %per annum compounded quarterly. the loan has to be paid in 3 years. calculate the amount of loan that is outstanding at the end of 2 years
Answers
The loan amount at the end of 2 years is Rs. 12,127 .
In the given question we have, amount Rs. 11500 is borrowed by investor at the interest rate of 6% per annum.
compund interest is defined as the addition of interest to the principal of loan.
principal (P) = 11500
If interest is compunded quarterly then time(t) = 3 years = 12 , rate ( r%) = 6/4% = 2/3 %
Using the formula of Amount ,
Amount = P( 1 + r / 100) ᵗ
= 11500( 1 + 2/ 300)⁸
= 12127.83 ~ 12128
compound interest = Amount - principal =
12128- 11500 = Rs. 628

if the interest for 5 years on Rs 3000 is Rs 525, find the interest on Rs 2200 for 6 years at the same rate of interest.
Answers
Using the formula of simple interest, the interest on Rs 2200 for 6 years at the same rate of interest is Rs 462.
In the given question,
The given principal amount = Rs 3000
The given time = 5 years
Interest amount = 525
Now finding the rate of interest.
As we know that the formula of simple interest.
I = P*R*T/100
525 = 3000*R*5/100
Multiply by 100 on both side we get
52500 = 15000*R
Divide by 15000 on both side
R = 52500/15000
R = 3.5
In the question we have to find the interest on Rs 2200 for 6 years at the same rate of interest.
To find the interest put the value in I = P*R*T/100
As given P=2200, R=3.5%, T=6 years
I = P*R*T/100
I = 2200*3.5*6/100
I = 462
