To find the angle of rotation θ between the previous x and y axes and the new x′ and y′ axes, we use the formula: cotangent of 2

The equation is the given one:

\cot 2\theta=\frac{A-C}{B}

Which is the same as:

\tan 2\theta=\frac{B}{A-C}

And the interval of the angle θ must be (0°,90°) so, 2θ must be (0°,180°).

So the statement is True.

How do the expressions 72 divided and -72divided by (-9) and compare when they are evaluated?
padilas [110]

Complete question is;

How do the expressions 72 divided by 9 and -72 divided by (-9) compare when they are evaluated?

A. They have different values and are different signs.

B. They have different values but are the same sign.

C. They have the same value but are different signs.

D. They have the same value and the same sign

Answer:

D. They have the same value and the same sign

Step-by-step explanation:

For 72 divided by 9,it is;

72/9 = 8

Usually when we don't have any sign in front of a number, it is said to be positive.

Thus, the answer can be expressed as; +8

Also, when -72 is divided by (-9), it is;

-72/-9

The negative signs will cancel out to give; 8

Similar to the first division, since no sign is attached to 8,it is said to be positive as +8.

This means both divisions yield same values and same signs
