Floating point numbers?

Which of the following will you select as X in the following series of clicks to lay the title over a chart: Chart Title box &gt

guapka [62]

Answer:

A

Explanation:

We are to lay a title over a chart, which means the position of the title should be above the chart.

When doing this, it will centre the title over the chart without duly interfering with the original size of the chart.

The option 'over chart' is incorrect as it is not a valid selection in the pane. Below chart as well is incorrect as we are to lay the title above the chart.

CODEHS: WHY is it important to know the difference between div and span?

DerKrebs [107]

Span and div are both generic HTML elements that group together related parts of a web page. However, they serve different functions. A div element is used for block-level organization and styling of page elements, whereas a span element is used for inline organization and styling.

Consider the helicopter of Example 2.1, but with a slightly different definition of the input and output. Suppose that, as in th

anzhelika [568]

Answer:

Solution: In this case, the system can be modeled as a function with two output signals,

$S: (R --> R) --> (R --> R)^{2}$

where

$(S(T_{y}))(t) = (x(t), y(t))$

where(x(t), y(t)) is the position of the tail in they plane. This model Is Clearly not linear. If the Input torque doubles, for example, the output values will not double. In fact, the output values are constrained to lie on a circle centered at the origin, regardless of the Input. For this reason, the model is BIBO stable. The output is always bounded. Thus, while our previous model was linear and unstable, this one Is nonlinear and stable. Which model is more useful?
