PLEASE SOMEONE TELL ME HOW THEY GOT 423 cm AS THE ANSWER FOR A. I NEED HELP WITH THIS QUESTION!!!!!!!!!!!!!
3241004551 [841]

From the setup of the problem, the "length of the top of the bookcase, measured along the attic ceiling" will be the hypotenuse of a right triangle, the length "AB". We have both the angle between AB and AC and the length of AC (3.24 meters), so we can use trigonometric identities.

The cosine of the 40 degree angle between AB and AC is equivalent to the length of AC divided by the length of AB. Equivalently, we have:

cos(40) = \frac{3.24}{h}

where "h", the hypotenuse, is the length we want. Rearranging the formula to solve for h we have that

$h = \frac{3.24}{cos(40)}$

which is 4.2295... meters. Converting to centimeters (multiplying by 100) we have that h = 422.95... centimeters, or if we round the value, h = 423 centimeters.

Which vector best describes the translation below?
Nimfa-mama [501]
<h3>Answer: Choice A)  <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule (x,y) \to (x+9, y). We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation (x,y) \to (x+a, y+b) is shortened to the translation vector notation < a, b >. In this case, a = 9 and b = 0.
