Explain why the expression 7•3x is not equal to the expression 21x
rusak2 [61]
The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>

A straight line has a slope of 2.08. Calculate the angle that the line makes with the x (horizontal) axis.
zubka84 [21]

Answer:

The angle that the line makes with x-axis of of 64.3º.

Step-by-step explanation:

Equation of a line, and angle with the x axis:

The equation of a line has the following format:

y = mx + b

In which m is the slope.

The angle that the line makes with the x axis is given by the angle which has tangent m, that is, a = \tan^{-1}{m}.

In this question:

We have that m = 2.08. So

a = \tan^{-1}{2.08} = 64.3

The angle that the line makes with x-axis of of 64.3º.

What is -2 square root of 20 negative square root of 125 in its simplest radical form
Ivenika [448]

Answer:

-7√5

Step-by-step explanation:

I'll transcribe your verbal question into a symbolic one as best I can:

-2√20 - √125

Note how √20 = √4*√5 and √125 = √25 *√5.  Thus,

your -2√20 - √125, after we've factored √5 out of both terms, becomes

-2(2)√5 - 5√5, or -2√5 - 5√5, which combines to form

-7√5 (answer)
