Answer: C. -1 2/5

Step-by-step explanation:

Given expression

(-3.5) (2/5)

Convert decimal into fraction

=(-35/10) (2/5)

=[(-35 ÷ 5) / (10 ÷ 5)] (2/5)

=(-7/2) (2/5)

Simplify by multiplication

=(-7 × 2) / (2 × 5)

Cancel out 2 on both numerator and denominator

=-7/5

Convert improper fraction to mixed fraction

=[tex]\boxed{-1\frac{2}{5} }[/tex]

Hope this helps!! :)

Large numbers can be easily written to a required significant figures using the standard notation. So that, the expression on Maria's calculator also can be written in standard form as 2.75 x [tex]10^{4}[/tex]

An exponential function can be used when dealing with large numbers, which can also be written in a standard form. This helps to simplify and express large numbers scientifically.

The value on Maria's calculator = 23,000 + 4.5E3

But,

4.5E3 = 4.5 x 1000

          = 4500

So that,

23,000 + 4.5E3 = 23,000 + 4500

                          = 27500

                          = 2.75 x [tex]10^{4}[/tex]

Thus,

23,000 + 4.5E3 = 2.75 x [tex]10^{4}[/tex]

Therefore, the expression on Maria's calculator also can be written in standard form as 2.75 x [tex]10^{4}[/tex]

The cross product distributes over sums, so we have

[O produto cruzado distribui somas, então temos]

(u + v) × (u - v) = (u × u) + (v × u) + (u × (-v)) + (v × (-v))

(u + v) × (u - v) = (u × u) + (v × u) - (u × v) - (v × v)

The cross product of a vector with itself is the zero vector, so

[O produto vetorial de um vetor com ele mesmo é o vetor zero, então]

(u + v) × (u - v) = 0 + (v × u) - (u × v) - 0

(u + v) × (u - v) = (v × u) - (u × v)

The cross product is anticommutative, meaning that for two vectors u and v,

[O produto vetorial é anticomutativo, o que significa que para dois vetores u e v,]

u × v = - (v × u)

So we end up with

[Então acabamos com]

(u + v) × (u - v) = (v × u) + (v × u)

(u + v) × (u - v) = 2 (v × u)

Given that u = (2, -3, -1) and v = (1, -1, 4), compute the cross product as follows:

[Dados esses vetores, calcule o produto vetorial:]

(1, -1, 4) × (2, -3, -1)

= ((1, 0, 0) - (0, 1, 0) + 4 (0, 0, 1)) × (2 (1, 0, 0) - 3 (0, 1, 0) - (0, 0, 1))

= 2 (1, 0, 0) × (1, 0, 0) - 2 (0, 1, 0) × (1, 0, 0) + 8 (0, 0, 1) × (1, 0, 0)

… … - 3 (1, 0, 0) × (0, 1, 0) + 3 (0, 1, 0) × (0, 1, 0) - 12 (0, 0, 1) × (0, 1, 0)

… … - (1, 0, 0) × (0, 0, 1) + (0, 1, 0) × (0, 0, 1) - 4 (0, 0, 1) × (0, 0, 1)

Recall the definition of the cross product:

[Lembre-se da definição de produto vetorial:]

(1, 0, 0) × (0, 1, 0) = (0, 0, 1)

(0, 1, 0) × (0, 0, 1) = (1, 0, 0)

(0, 0, 1) × (1, 0, 0) = (0, 1, 0)

The product reduces to

[O produto se reduz a]

(1, -1, 4) × (2, -3, -1)

= -2 (0, 1, 0) × (1, 0, 0) + 8 (0, 0, 1) × (1, 0, 0)

… … - 3 (1, 0, 0) × (0, 1, 0) - 12 (0, 0, 1) × (0, 1, 0)

… … - (1, 0, 0) × (0, 0, 1) + (0, 1, 0) × (0, 0, 1)

= 2 (0, 0, 1) + 8 (0, 1, 0) - 3 (0, 0, 1) + 12 (1, 0, 0) + (0, 1, 0) + (1, 0, 0)

= - (0, 0, 1) + 9 (0, 1, 0) + 13 (1, 0, 0)

= (13, 9, -1)

Finally,

[Finalmente,]

(u + v) × (u - v) = 2 (13, 9, -1) = (26, 18, -2)

An equation to model the sum of the situation will be +1 - 1 = 0.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that "A hydrogen atom has a zero charge because it has been negatively charged electron and one positively charged proton."

The expression for the given situation will be written as below:-

+1 - 1 = 0

Therefore, the equation to model the sum of the situation will be +1 - 1 = 0.

Answer:

Set the denom to 0 and solve.

x^2 - 16 = 0 --> x = -4,4

This means the vertical asymptote is 4, -4.

Therefor, the domain is for all real numbers that are not 4, -4.

We ignore the top because if the numerator was 0, it's still a number. But if the denom was 0, then it would be impossible (you can't divide by 0). So for all numbers that can go into the denom that aren't 0, is your domain.

Answer:

Step-by-step explanation:

Consider the function and its inverse shown in the second attachment. The function is ...

  f = {(a, 3), (b, 1), (c, 2)}

The inverse function is ...

  f^-1 = {(3, a), (1, b), (2, c)}

You will notice that the "x" and "y" of each pair are swapped between the function and its inverse. That is the point of an inverse function. It gives you the input that caused the function to create the output. For example, the pair (3, a) in the above inverse function tells you that the output 3 was the result of an input of 'a' to the original function.

__

On a graph, the swapping of input and output is essentially equivalent to relabeling the axes. If we keep the same x- and y-axis labels, it is equivalent to reflecting the function graph across the line y=x. That reflection is represented by the transformation (x, y) ⇒ (y, x).

__

The point of the exercise here is for you to identify some ordered pairs of one of the functions and realize that the inverse function reverses their order. You are to see that the graph of the function and its inverse are reflections of each other across the diagonal line y=x.

The distance between two points on the coordinate geometry is [tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]. The first stripe is 10 inches long.

Given that:

[tex](x_1,y_1) = (2,0)[/tex]

[tex](x_2,y_2) = (5,4)[/tex]

First, we calculate the number of units using distance formula:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

So, we have:

[tex]d = \sqrt{(2 - 5)^2 + (0 - 4)^2}[/tex]

[tex]d = \sqrt{(-3)^2 + (-4)^2}[/tex]

[tex]d = \sqrt{25}[/tex]

Take positive square root

[tex]d = 5[/tex]

From the question, we understand that each unit is 2 inches.

So, the length of the stripe is:

[tex]Length = 2 \times d[/tex]

[tex]Length = 2 \times 5[/tex]

[tex]Length = 10[/tex]
