B) 231

To get the answer, you first need to figure out how many men are in the book club:
- Multiply the total number of members (315) by the fraction of members that are men (4/15)
- (4/15) * 315
- Multiply 4 by 315, and then divide by 15.
- This will give you the number of men (84)

Then you need to figure out how many women there are:
- Subtract the number of men (84) from the total number of members (315)
- 315 total members - 84 male members = 231 female members

M+f=315
m=4*315/15
m=1260/15
m=84

f=315-84
f=231

state whether each expression is meaningful. if not, explain why. if so, state whether it is a vector or a scalar.
DanielleElmas [232]

The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product so options (b), (d), and (e) are not meaningful.

<h3>What is a vector?</h3>

An item with both magnitude and direction is referred to be a vector.

A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.

A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.

The dot product of two vectors gives scalar quantity while the cross product gives a vector quantity.

Now,

In option (B) ;

a Х (b . c) now here b . c is a scalar quantity and we can not cross multiply a scalar with a vector.

In option (D) ;

(a.b) Χ (c.d) where we cannot multiply two scalars by cross product.

In option (E);

a.(b.c) we can not multiply two scalars by the dot product.

Hence "The dot product of two vectors gives scalar quantity and between scalar quantity, we can not apply any product".

Triangle A'B'C' is the image of triangle ABC under a rotation about point Q.<br><br>​
yan [13]

9514 1404 393

Answer:

  True; about 120° CCW rotation about Q

Step-by-step explanation:

Triangle A'B'C' appears to be congruent to triangle ABC and about the same distance from point Q. The angle of rotation from ABC to A'B'C' appears to be about 120° counterclockwise when measured using a geometry program.

Triangle A'B'C' is the image of triangle ABC under rotation about 120° CCW about point Q.

_____

<em>Additional comment</em>

If choices of rotation angle are ±135° or ±165°, the best choice would be ...

  135°
