If the shortest leg of the small triangle is 4 in and the hypotenuse is 12 in and the shortest leg of the large triangle 8 in, then the length of the hypotenuse of the large triangle is 24 inches.

We know that two triangles are proportional if their corresponding sides are in proportion to each other. That is, the ratio of the lengths of the corresponding sides is the same for both triangles.

Let's denote the length of the hypotenuse of the large triangle by "h". We can set up a proportion using the given information:

shortest leg of small triangle / hypotenuse of small triangle = shortest leg of large triangle / hypotenuse of large triangle

Plugging in the values we get:

4/12 = 8/h

Simplifying the equation we get:

h = (12*8)/4 = 24

To explain the solution, we used the fact that similar triangles have proportional sides. We then used the given information about the lengths of the sides of the small and large triangles to set up a proportion and solve for the unknown length of the hypotenuse of the large triangle.

The key to this problem was recognizing the relationship between similar triangles and using that relationship to set up and solve a proportion.

The missing value in the expression A = -2(x-9)² + ? is 162, which represents the maximum area of the storage bin.

A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves.

To complete the perfect square, we need to factor out the coefficient of the squared term (-2) from the expression:

A = -2x² + 36x

A = -2(x² - 18x)

Next, we need to add and subtract the square of half the coefficient of the x-term (-18/2 = -9) inside the parentheses:

A = -2(x² - 18x + (-9)² - (-9)²)

Simplifying the expression inside the parentheses, we get:

A = -2[(x - 9)² - 81]

Distributing the -2, we get:

A = -2(x - 9)² + 162

Answer:

Step-by-step explanation:

1/(x+1)(x-2) is the simplified form of the expression

Given the expression below

x+2/4x²+5x+1 · 4x+1/x²-4

Factorise the quadratic expressions

4x²+5x+1 = 4x²+4x + x+1

4x²+5x+1 = 4x(x+1)+1(x+1)

4x²+5x+1 = (4x+1)(x+1)

For the expression x²-4

x²-4 = (x+2)(x-2)

Substitute

x+2/4x²+5x+1 · 4x+1/x²-4 = x+2/(4x+1)(x+1) · 4x+1/(x+2)(x-2)

x+2/4x²+5x+1 · 4x+1/x²-4 = 1/x+1 · 1/x-2

For given linear inequalities in step 3 and 7 properties shown are Commutative property and addition property of inequality.

What exactly is a linear inequality?

In mathematics, inequality denotes a mathematical statement with no equal sides. An inequality happens in mathematics when a connection results in a non-equal comparison of two expressions or two numbers. Any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠), replace the equal sign "=" in the sentence. In mathematics, inequalities are classified into three types: polynomial inequalities, rational inequalities, and absolute value inequalities.

The characters "< and >" denote severe inequalities, whereas ‘≤’ and ‘≥’  denote slack inequalities. A linear inequality looks to be a linear equation, however the formula is different.

Now,

As stated in Commutative property the order in addition does not matter and in addition property the value added on both sides does not affect the result.

In step 3 we can write this as 5x-x-5<11x+x-21

which will not change result and

The weighted average price index is 171, which means that the average price of the components in Year 2 was 171% of their average price in Year 1.

To compute the weighted average of relatives, we need to find the weighted average of the ratio of the prices of each component in Year 2 to Year 1. Let's call this ratio the "relative price".

Relative price for component A = Po Year 2 / Po Year 1 = 6.00 / 3.00 = 2.00

Relative price for component B = Pn Year 2 / Pn Year 1 = 8.50 / 6.80 = 1.25

Relative price for component C = Pn Year 2 / Po Year 1 = 17.68 / 20.80 = 0.85

Next, we'll find the weighted average of the relatives by summing the product of each relative price and its corresponding standard weight, and dividing by the sum of the standard weights.

Weighted average of relatives = (2.00 * 16 + 1.25 * 6 + 0.85 * 2) / (16 + 6 + 2)

= (32 + 7.5 + 1.7) / 24

= 41.2 / 24

= 1.71

The weighted average of relatives is 1.71, which means that the average price of the components increased by 71% from Year 1 to Year 2.

To compute the weighted average price index, we'll use the weighted average of relatives as a reference point and multiply it by 100.

Weighted average price index = Weighted average of relatives * 100

= 1.71 * 100

= 171

Therefore the weighted average price index is 171, which means that the average price of the components in Year 2 was 171% of their average price in Year 1.

The derivative of the composite function f(x) = (3 · x · cos x + √x) / [5 · x² · (sin x + 1)] is equal to f'(x) = [[3 · cos x - 3 · x · sin x + (1 / 2√x)] · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · [5 · x · (sin x + 1) + 5 · x² · cos x]] / [5 · x² · (sin x + 1)]².

In this problem we must determine the derivative of the composite function f(x) = (3 · x · cos x + √x) / [5 · x² · (sin x + 1)]. This can be done by using the following derivative rules:

Derivative of the addition of two functions

d [f(x) + g(x)] / dx = df(x) / dx + dg(x) / dx

Derivative of the product of two functions

d [f(x) · g(x)] / dx = [df(x) / dx] · g(x) + f(x) · [dg(x) / dx]

Derivative of the division of two functions

d[f(x) / g(x)] / dx = [[df(x) / dx] · g(x) - f(x) · [dg(x) / dx]] / [g(x)]²

Derivative of a function and a constant

d [c · f(x)] / dx = c · df(x) / dx

Derivative of a power function

d [xⁿ] / dx = n · xⁿ⁻¹

Derivative of cosine

d [cos x] / dx = - sin x

Derivative of sine

d [sin x] / dx = cos x

Now we proceed to determine the derivative of the function by derivative rules:

f'(x) = [d [3 · x · cos x + √x] / dx · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · d [5 · x² · (sin x + 1)] / dx] / [5 · x² · (sin x + 1)]²

f'(x) = [[3 · cos x - 3 · x · sin x + (1 / 2√x)] · [5 · x² · (sin x + 1)] - (3 · x · cos x + √x) · [5 · x · (sin x + 1) + 5 · x² · cos x]] / [5 · x² · (sin x + 1)]²

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the information that the polynomial function P(x) has leading coefficient 1, has roots of multiplicity 2 at x = 1 and x = 0, and a root of multiplicity 1 at x = -5, we can use this information to find a possible formula for P(x).

A polynomial function's roots are the values of x that make the function equal to zero. If a root has multiplicity n, it means that (x - root) is a factor of the polynomial function n times.

So, based on the given information, we know that P(x) must be divisible by the factors (x - 1)^2, (x - 0)^2, and (x + 5), and that the leading coefficient must be 1.

Putting it all together, a possible formula for P(x) is:

P(x) = (x - 1)^2 (x - 0)^2 (x + 5) = (x^2 - 2x + 1)(x^2)(x + 5) = x^6 - 7x^5 + 17x^4 - 22x^3 + 17x^2 - 7x + 5

So, the possible formula for P(x) is P(x) = x^6 - 7x^5 + 17x^4 - 22x^3 + 17x^2 - 7x + 5.

Answer:   [tex]P(\text{x}) = \text{x}^2(\text{x}-1)^2(\text{x}+5)[/tex]

Explanation:

If k is a root of P(x), then x-k is a factor. The multiplicity is the exponent for that factor.

For instance, the root x = 1 with multiplicity 2 leads to the factor [tex](\text{x}-1)^2[/tex]

The leading coefficient is the number out front. For example, if the leading coefficient was 8, then we'd have [tex]P(\text{x}) =8\text{x}^2(\text{x}-1)^2(\text{x}+5)[/tex]

However, we change that "8" to a "1" since the leading coefficient is 1 here.

That's how we get to

[tex]P(\text{x}) = 1\text{x}^2(\text{x}-1)^2(\text{x}+5)[/tex] aka [tex]P(\text{x}) = \text{x}^2(\text{x}-1)^2(\text{x}+5)[/tex]

Optionally if you were to expand everything out, combine like terms, and simplify then you'd get

[tex]P(\text{x}) = \text{x}^2(\text{x}-1)^2(\text{x}+5) = \text{x}^5 + 3\text{x}^4- 9\text{x}^3+5\text{x}^2[/tex]

I don't recommend doing this because you lose the information about the roots along with their corresponding multiplicities. It's better to keep things factored.

You can use a graphing tool like Desmos or GeoGebra to verify the answer.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Two intersecting lines will have exactly one solution (i.e., a unique point of intersection) if and only if they are not parallel.

In other words, if the slopes of the two lines are different, they will intersect at a single point. This is because the slopes of the lines determine how steep they are, and if they are not the same, they will eventually cross at a single point.
