The length of a diagonal will be 109 cm.

What is Rectangle?

A rectangle is a quadrilateral that has parallel sides equal to each other and all the four angles are equal to 90 degrees.

Given that;

Length of a rectangle = 60 cm

Width of a rectangle = 91 cm

Now,

Since, We know that;

Diagonal of a rectangle (D) = √Length² + Width²

Substitute all the values we get;

Diagonal of a rectangle (D) = √Length² + Width²

                                         = √60² + 91²

                                         = √3600 + 8,281

                                         = √11,881

                                         = 109

So, Diagonal of a rectangle = 109 cm.

Thus, The length of a diagonal will be 109 cm.

The order of the numbers from least to greatest will be 97%, 1.74, 2 4/5, and 18/5.

I rewrite the numbers in equivalent forms, this was illustrated in decimals to make it easier.

From the information, the data set includes the following numbers: eighteen over 5, two and four fifths, 97%, and 1.74. This will be:

18/5 = 3.6

2 4/5 = 2.8

Answer:

A. {2.82, √8, √11, 3 1/2}

Step-by-step explanation:

A. {2.82, 2.83, 3.32, 3.5}

√8 = 2.82842712475 or 2.83 when rounded to the nearest hundredth.

√11 = 3.31662479036 or 3.32 when rounded to the nearest hundredth.

To find the square root you multiply a factor of a number by itself in order to get that number.

3 1/2, or 7/2 = 3.5

To convert a fraction into a decimal you divide the numerator by denominator.

B. {2.24, -2.45, 2.5, -3}
√5 = 2.2360679775 or 2.24 when rounded to the nearest hundredth.

-√6 = -2.44948974278 or -2.45 when rounded to the nearest hundredth.

2 1/2, or 5/2 = 2.5

C. {-4, -4.12, -4.24, -4.36}

The expansion and simplified form of the expression [(x+3)(2x-1)(x+4)] will be (2x³ + x² - 25x - 12).

As per the question statement, we are provided with the expression of [(x+3)(2x-1)(x+4)] where three separate factors of the variable "x" are multiplied with each other.

We are required to expand and simplify the above-mentioned expression to obtain our desired answer.

Given, [(x + 3)(2x - 1)(x + 4)]

= [{(x + 3)*(2x - 1)}(x + 4)]

= [{(x*2x) - (x*1) + (3*2x) - (3*1)}(x + 4)]

= [(2x² - x - 6x -3)(x + 4)]

= [(2x² - 7x -3)(x + 4)]

= [(2x²*x) + (2x²*4) - (7x*x) - (7x*4) - (3*x) - (3*4)]

= [2x³ + 8x² - 7x² - 28x - 3x - 12]

= [2x³ + (8x² - 7x²) - (28x + 3x) - 12]

6x+26x-10=8(4x+10) quadratic equation has no solution.

First, Simplify the equation:

6x + 26x + (-10) = 8(4x + 10)

Now, reorder the terms:

(-10) + 6x + 26x = 8(4x + 10)

Combine the like terms:

6x + 26x = 32x

-10 + 32x = 8(4x + 10)

Then, reorder the terms:

-10 + 32x = 8(10 + 4x)

-10 + 32x = (10 × 8 + 4x × 8)

-10 + 32x = (80 + 32x)

Add '-32x' to each side of the equation.

-10 + 32x + -32x = 80 + 32x + -32x

Again, Combine like terms:

32x + -32x = 0

-10 + 0 = 80 + 32x + -32x

-10 = 80 + 32x + -32x

Repetitively, Combine like terms:

32x + -32x = 0

-10 = 80 + 0

-10 = 80

After Solving,

-10 = 80

Thus, there is no further variable to solve.

∴ This equation is invalid, the left and right sides are not equal, therefore there is no solution.

The expression 1/(2x²) - 7y is not a polynomial because it has a negative exponent

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

A polynomial is an expression that involves only the operations of addition, subtraction, multiplication, and positive exponent powers of variables. If the expression has a negative exponent, it is not a polynomial.

Explanation:

Given that,

[tex]\frac{dA}{dt}[/tex] = -4

The surface area of the snow ball = 4π[tex]r^{2}[/tex]

Let the surface area = A

If A denotes the surface area and D the diameter then,

A = 4π[tex]r^{2}[/tex] = 4π[tex](\frac{D}{2} )^{2}[/tex]

⇒ A = π[tex]D^{2}[/tex]

Differentiate with respect to r,

[tex]\frac{dA}{dD}[/tex] = 2πD

By using chain rule,

[tex]\frac{dA}{dD}[/tex] = [tex](\frac{dA}{dt})[/tex][tex](\frac{dt}{dD})[/tex] = [tex]\frac{\frac{dA}{dt}}{\frac{dD}{dt}}[/tex]

⇒ 2πD = [tex]-\frac{4}{\frac{dD}{dt}}[/tex]

∴ [tex]\frac{dD}{dt}[/tex] = [tex]-\frac{4}{2\pi\\D}[/tex]

when D = 9,

[tex]\frac{dD}{dt}[/tex] = [tex]-\frac{4}{18\pi}[/tex]

∴ [tex]\frac{dD}{dt}[/tex] = [tex]-\frac{2}{9\pi}[/tex]

so, the diameter is decreasing at a rate of [tex]\frac{2}{9\pi}[/tex] .
