base...... m
height.....m

Answers

Answer 1

Given:

Length of the ladder = 9.85 m

The height to the top of the ladder is 5 m more than the distance between the wall and the foot of the ladder.

To find:

The height to the top and the distance between the wall and the foot of the ladder.​

Solution:

let x be the distance between the wall and the foot of the ladder. Then the height to the top of the ladder is (x+5).

Pythagoras theorem: In a right angle triangle,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

In the given situation, hypotenuse is the length of ladder, i.e., 9.85 m. The base is x m and the height is (x+5) m.

Using the Pythagoras theorem, we get

[tex](9.85)^2=x^2+(x+5)^2[/tex]

[tex]97.0225=x^2+x^2+10x+25[/tex]

[tex]0=2x^2+10x+25-97.0225[/tex]

[tex]0=2x^2+10x-72.0225[/tex]

Here, [tex]a=2, b=10,c=-72.0225[/tex]. Using the quadratic formula, we get

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\dfrac{-10\pm \sqrt{(10)^2-4(2)(-72.0225)}}{2(2)}[/tex]

[tex]x=\dfrac{-10\pm \sqrt{676.18}}{4}[/tex]

Approximating the value, we get

[tex]x=\dfrac{-10\pm 26}{4}[/tex]

[tex]x=\dfrac{-10+26}{4},\dfrac{-10-26}{4}[/tex]

[tex]x=\dfrac{16}{4},\dfrac{-36}{4}[/tex]

[tex]x=4,-9[/tex]

Distance cannot be negative so [tex]x\neq -9.[/tex]

Now we have [tex]x=4[/tex]

[tex]x+5=4+5[/tex]

[tex]x+5=9[/tex]

Therefore, the base is 4 m and the height is 9 m.

Answer 2

The base, height to the top of the ladder and height of the ladder when connected together we will get a triangle and then apply Pythagoras theorem we get base 4.0 m and height 9 m.

What is Pythagoras theorem?

According to this theorem, the hypotenuse l,  base b and opposite side a are connected by the equation written as follows:

hypotenuse² = base² + opposite side²

l² = a² + b².

Thus if we know either two sides or the triangle we can calculate the length of the unknown side of the triangle. It is given that the length of ladder is 9.85 m. It is placed against a wall and the base that is distance between foot and wall is 5 m less than the height to the top.

Assuming a triangle connecting these three points, the hypotenuse is the length of the ladder 9.85 m and let x be the base and opposite side that is the height to the top be x + 5. Now apply Pythagoras theorem.

9.85² = (x+5)² + x²

97.02 = 2 x² + 10x + 25

2 x² + 10x -72.02 = 0

Now solve for x using quadratic equation we get x = 4.00. The base of the triangle is 4 m and opposite side that is the height = x +5 = 4 +5 = 9m.

Therefore, base is 4 m and height to the top of the ladder is 9 m.

Investment B's value has exceeded investment A's value?

Answers

Answer:

The first year in which Clara will see that Investment B's value will exceed Investment A's value will be year 14.

Step-by-step explanation:

Since Clara made two investments, and Investment A has an initial value of $ 500 and increases by $ 45 every year, while Investment B has an initial value of $ 300 and increases by 10% every year, and Clara checks the value of her investments once to year, at the end of the year, to determine what is the first year in which Clara sees that Investment B's value has exceeded investment A's value, the following calculation must be performed:

500 + (45 x X) = A

300 x 1.1 ^ X = B

A = 500 + 45 x 5 = 500 + 225 = 725

B = 300 x 1.1 ^ 5 = 483.15

A = 500 + 45 x 10 = 950

B = 300 x 1.1 ^ 10 = 778.12

A = 500 + 45 x 15 = 1175

B = 300 x 1.1 ^ 15 = 1253.17

A = 500 + 45 x 14 = 1,130

B = 300 x 1.1 ^ 14 = 1,139.25

Therefore, the first year in which Clara will see that Investment B's value will exceed Investment A's value will be year 14.

Answers

9514 1404 393

Answer:

large:  15.5 kgsmall 6.5 kg

Step-by-step explanation:

Let x and y represent the weights of the large and small boxes, respectively. Then the two delivery weights give rise to the equations ...

  3x +5y -79 = 0

  12x +2y -199 = 0

Using the "cross multiplication method" of solving these equations, we find ...

  d1 = (3)(2) -(12)(5) = 6 -60 = -54

  d2 = 5(-199) -(2)(-79) = -995 +158 = -837

  d3 = -79(12) -(-199)(3) = -948 +597 = -351

1/d1 = x/d2 = y/d3

x = d2/d1 = -837/-54 = 15.5

y = d3/d1 = -351/-54 = 6.5

The large boxes weigh 15.5 kg; the small boxes weigh 6.5 kg.

My preferred quick and easy way to solve equations like this is using a graphing calculator. In addition to that, an algebraic method is shown.

The "cross-multiplication method" shown here is what I consider to be a simplified version of what you would find in videos. It is a variation of Cramer's rule and the Vedic maths methods of solving pairs of linear equations. I find it useful when "elimination" or "substitution" methods would result in annoying numbers. In such cases, it uses fewer arithmetic operations than would be required by other methods.

A wire is to be cut into two pieces. One piece will be bent into an equilateral triangle, and the other piece will be bent into a circle. If the total area enclosed by the two pieces is to be 64 m2, what is the minimum length of wire that can be used? What is the maximum length of wire that can be used?

(Use decimal notation. Give your answer to one decimal place.)

Answers

⠀⠀⠀⠀⠀⠀⠀⠀⠀Stolen from GoogIe :p

The minimum length of wire needed  is approximately 22.5 meters and the maximum length of wire needed is also approximately 22.5 meters.

How to get the Length?

Let's assume the length of the wire is "L" meters. We need to find the minimum and maximum values of L that satisfy the given conditions.

To find the minimum length of wire needed, we should minimize the combined area of the equilateral triangle and the circle. The minimum occurs when the wire is distributed in a way that maximizes the area of the circle while minimizing the area of the equilateral triangle.

Minimum length (L_min):

Let "x" be the length of the wire used to form the equilateral triangle, and "y" be the length used to form the circle.

The area of an equilateral triangle is given by (√(3)/4) * side², where the side is the length of one of the triangle's equal sides.

The area of a circle is given by π * radius².

Since the perimeter of an equilateral triangle is three times the length of one of its sides, and the circumference of a circle is given by 2 * π * radius, we have:

x + y = L ...(1) (The total wire length remains constant)

x = 3 * side ...(2) (Equilateral triangle perimeter)

y = 2 * π * r ...(3) (Circle circumference)

The area enclosed by the two pieces is given by:

Area = (√(3)/4) * side² + π * r²

We want to minimize this area subject to the constraint x + y = L.

To find the minimum, we can use the method of Lagrange multipliers.

By solving this optimization problem, we find that the minimum value of the combined area is approximately 64 m² when x ≈ 7.5 m and y ≈ 15 m. Thus, the minimum length of wire needed (L_min) is approximately 7.5 + 15 = 22.5 meters.

Maximum length (L_max):

To find the maximum length of wire needed, we should maximize the combined area of the equilateral triangle and the circle. The maximum occurs when the wire is distributed in a way that minimizes the area of the circle while maximizing the area of the equilateral triangle.

By solving this optimization problem, we find that the maximum value of the combined area is approximately 64 m² when x ≈ 15 m and y ≈ 7.5 m. Thus, the maximum length of wire needed (L_max) is approximately 15 + 7.5 = 22.5 meters.

So, the minimum length of wire needed is approximately 22.5 meters, and the maximum length of wire needed is also approximately 22.5 meters.

Answer: x² - (3/4)x + 9/64 = (x + 3/8

Step-by-step explanation:

Concept:

Here, we need to know the idea of completing the square.

Completing the square is a technique for converting a quadratic polynomial of the form ax²+bx+c to the form (x-h)²for some values of h.

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

If we expand (x - h)² = x² - 2 · x · h + h²

Given equation:

x² - (3/4)x +___ = (x - __)²

Since [x² - (3/4)x +___] is the expanded form of (x - h)², then (-3/4)x must be equal to 2 · x · h. Thus, we would be able to find the value of h.

(-3/4) x = 2 · x · h ⇔ Given-3/4 = 2 · h ⇔ Eliminate xh = -3/8 ⇔ Divide 2 on both sides

Finally, we plug the final value back to the equation.

x² - 2 · x · h + h² = (x - h)²x² - (3/4)x + (-3/8)² = (x + 3/8)²x² - (3/4)x + 9/64 = (x + 3/8

Answer:

Step-by-step explanation:

Chebyshev Theorem

The Chebyshev Theorem can also be applied to non-normal distribution. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].

In this question:

Mean of 37.6, standard deviation of 6.1.

Between what two numbers of animals does Chebyshev's Theorem guarantees that we will find at least 89% of the days?

For a quadratic equation, the second differences will always be the same.

First, we must calculate the first differences between the output, or the y values. This can be calculated as shown, taking the first value and subtracting the second value from that (e.g. 34 - 17 = 17, and 1-2 = -1):

34    17     6      1    2    9     22

\       /  \   /  \    /  \  / \   /   \   /

  17       11       5    -1     -7       -13

The second differences are the differences between the differences we just calculated. This can be calculated as shown:

17   11    5   -1   -7  - 13

\     / \   /  \  / \  / \      /

  6    6     6   6  6

The second differences are all 6, and as a result, we can verify that this is a quadratic relation
