a tree of 14 m height is broken so that its top touches ground and makes an a 60 degeree.find the length of broken part of tree
Answer:
98 - 24√3 is your answer dear.
Step-by-step explanation:
Let the length of broken part of the tree = 14 - x
For finding x
sin60° = √3/2 = x /14-x
14√3 - √3x = 2x
14√3 = 2x + √3x
14√3 = (2 + √3)x
x = 14√3/(2 + √3)x
after rationalisation
x = 24√3 - 84
substract it 14 - (24√3 - 84)
YOU'LL GET 98 - 24√3 WHICH IS YOUR ANSWER.

A sales associate at an electronics store earns 9.5% commission on her total yearly sales. Last year, the sales associate earned an income of $11,875. What is the total amount of sales that the associate made last
year?
The total amount of sales made by the associate last year is $124,000.
What is defined as the percentage?The term percent means "out of every hundred" or "per hundred."
The term is based on the Latin phrase per centum, which means "by the hundred." So, for every 100 units of something, a single percent represents one of those hundred units, or one percent.To calculate a percentage, divide the fraction of the total by the total but also multiply by 100.Now, as per the given question;
Let the total sales done by the associate in last year is 'x'.
The commission earned on the total sales is 9.5%
Thus, 9.5% of x can be written as;
= (9.5×x)/100
The total earning from the sales is $11,875.
Thus,
(9.5×x)/100 = 11,875
Simplify the equation to find x.
x = (11,875×100)/9.5
x = 125,000
Therefore, the total sales done by the commissioner in last year was $125,000.

are the Lines parallel, perpendicular, or neither?
Answer: The lines are perpendicular.
To solve, we can find the slope of each line and compare them to the qualities of parallel and perpendicular lines.
Vocabulary and SlopeParallelThe lines run in the same direction and can never meet. If the lines are parallel, they would have the same slope.
PerpendicularThe lines meet at 90°. If the lines are perpendicular, the slopes would be negative reciprocals of each other.
The negative reciprocal of a number is when we flip the fraction upside down and change the negative sign.To check this, we could multiply the two slopes together and the answer will be –1.How to Find SlopeUse the slope formula. Slope is represented by the letter m.
[tex]\displaystyle{ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} }[/tex]
On a graph, we write points as (x, y). To use the formula, we need two points on each line. The question already shows what points we can use.
Choose which point coordinates will be x₁, y₁ and x₂, y₂.Substitute the points into the formula.Solve.a) Blue lineThe points are (2, -7) and (6, 5). The variables can be:
x₁ = 2
y₁ = -7
x₂ = 6
y₂ = 5
Substitute into the slope formula and solve for slope.
[tex]\displaystyle{ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} }[/tex]
[tex]\displaystyle{ m=\frac{5--7}{6-2} }[/tex] Simplify the numerator.
[tex]\displaystyle{ m=\frac{5+7}{6-2} }[/tex] Simplify the numerator and denominators.
[tex]\displaystyle{ m=\frac{12}{4} }[/tex] Divide.
[tex]\displaystyle{ m=3 }[/tex] Solved for slope of blue line.
b) Green lineThe points are (-1, 5) and (8, 2). The variables can be:
x₁ = -1
y₁ = 5
x₂ = 8
y₂ = 2
Substitute into the slope formula and solve for slope.
[tex]\displaystyle{ m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} }[/tex]
[tex]\displaystyle{ m=\frac{2-5}{8--1} }[/tex] Simplify the denominator.
[tex]\displaystyle{ m=\frac{2-5}{8+1} }[/tex] Simplify the numerator and denominators.
[tex]\displaystyle{ m=\frac{-3}{9} }[/tex] Simplify the fraction.
[tex]\displaystyle{ m=-\frac{1}{3} }[/tex] Solved for slope of green line.
Compare the SlopesThe slopes are:
[tex]\displaystyle{-\frac{1}{3}}[/tex] [tex]3[/tex], which is the same as [tex]\displaystyle{\frac{3}{1}}[/tex]We know the slopes are not the same, so the lines are not parallel.
However, the slopes are negative reciprocals of each other. The fraction is flipped and the negatives are different.
If we multiply the slopes together, we would get –1:
[tex]\displaystyle{-\frac{1}{3}*\frac{3}{1}=-1}[/tex]
∴ The lines are perpendicular.

5. Mr. Franklin needs to purchase 60 AA batteries. A nearby store sells a 20-pack of AA batteries for $12.49 and a 12-pack of the same batteries for $7.20. Would it be less expensive for Mr. Franklin to purchase the batteries in 20-packs or 12-packs? What is the difference between the costs of one battery from each pack?
Answer: See explanation
Step-by-step explanation:
A nearby store sells a 20-pack of AA batteries for $12.49. Therefore, the cost of 1 pack will be:
= $12.49 / 20
= $0.6245
The store also sells a 12-pack of the same batteries for $7.20. The cost per pack will be:
= $7.20 / 12
= $0.6
Therefore, it will be less expensive for Mr. Franklin to purchase the batteries in 12 packs.
The difference between the costs of one battery from each pack will be:
= $0.6245 - $0.60
= $0.0245
Answer:
$0.0245

Why can't you have a shoe size of 4.5 and a height of 72 inches?
Answer:
Ok, lemme say something.
4.5 shoes are for 9 inch feet.
Dont think a 6 foot person is gonna fit tbh.
Step-by-step explanation:
A shoe size is for relation to feet size. Your feet grow from your height too, along with weight. If you are 6 feet, your feet are gonna be more than at least 1 foot.
4.5 shoes are for 9 inch feet
1 foot = 12 inches.
12 > 9.
12-9=3.

Write y+4=−1/2(x−2) in slope intercept form .
Answer:
y = - [tex]\frac{1}{2}[/tex] x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y + 4 = - [tex]\frac{1}{2}[/tex] (x - 2) ← distribute
y + 4 = - [tex]\frac{1}{2}[/tex] x + 1 ( subtract 4 from both sides )
y = - [tex]\frac{1}{2}[/tex] x - 3 ← in slope- intercept form

1. What can you say about the value of a polynomial
when P(a)=0
Answer:
The expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0
Step-by-step explanation:
The question would be better answered if you gave option. Since there is no option, I'll answer the question generally.
Given
[tex]P(a) = 0[/tex]
The above expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0
Take for instance, the polynomial is:
[tex]P(x) = x^2 - x - 2[/tex]
And the divisor is x - 2, then P(2) = 0 because (x - 2) is a divisor of the equation.
[tex]\frac{P(x)}{x} =\frac{x^2 - x - 2}{x - 2}[/tex]
Factorize the numerator
[tex]\frac{P(x)}{x} =\frac{(x- 2)(x + 1)}{x - 2}[/tex]
[tex]\frac{P(x)}{x} =x + 1}[/tex]
See that x - 2 is a divisor
To check
Set x - 2 to 0
[tex]x -2 = 0[/tex]
[tex]x = 2[/tex]
So, we have:
[tex]P(x) = x^2 - x - 2[/tex]
[tex]P(2) = 2^2 - 2 - 2[/tex]
[tex]P(2) = 4 - 2 - 2[/tex]
[tex]P(2) = 0[/tex]
