A swift can fly at 160km/h. what is the speed in m/s? show clearly how you worked out your answer.

Oduvanchick [21]

Step-by-step explanation:

$Given \: speed \: = 160km| h \\ To \: find \: speed \: in \: m|s \\ Solution \: speed \: = 160km|h \\ = (160 \times \frac{5}{18}) \: m|s \\ = \frac{800}{18} m|s \\ = 44.44m|s \\ Hence \: speed \: = 44.44m|s...$

Answer: True.

Step-by-step explanation:

A conditional distribution in this case is a probability distribution for a sub-population. In other words, it represent the probability that a randomly selected item in a sub-population has a characteristic we’are interested in .

Write an EQUATION with an undefined slope:

Phantasy [73]

Answer:

Example of an equation with an undefined slope: x = 2

Step-by-step explanation:

<h2>Definitions</h2>

The standard form of linear equations with an undefined slope is x = a, whose graph represents a vertical line. The value of a in the standard form is the x-intercept, (a, 0).

The slope is the ratio of the vertical change in y-values to the horizontal change in x-values.

$\displaystyle\mathsf{Slope(m) =\:\frac{\triangle y}{\triangle x}\:=\frac{y_2 - y_1}{x_2 - x_1}}$

The slope of a vertical line is undefined because if we were to solve its slope, the denominator will be zero. As we know, division by zero is an undefined operation.

<h2>Example:</h2>

For example, suppose that we have the following points (2, 5) (2, 10).

Let (x₁, y₁) = (2, 5)

(x₂, y₂) = (2, 10)

Substitute these values into the slope formula:

$\displaystyle\mathsf{Slope(m) =\:\frac{\triangle y}{\triangle x}\:=\frac{y_2 - y_1}{x_2 - x_1}\:=\:\frac{10\:-\:5}{2\:-\:2}\:=\frac{5}{0}}$

Dividing the numerator, 5, by the denominator, 0, will have an undefined quotient.

Thus, the equation of the vertical line will be: x = 2, where a = 2.
