Answer: 16
Step-by-step explanation:
an area is always calculated by multiplying 2 dimensions.
when changing the dimensions, then the change factors for EACH dimension go into the calculation too.
therefore, when both dimensions of an area are enlarged 4 times, then the area is enlarged 4×4 = 16 times.
this just propagates to the whole surface area of an object, as each individual area of the overall surface area is enlarged by the same factor. and so, the sum of all the individual areas (= altogether the surface area of the object) is also enlarged in total by the same factor.
just think
16×a + 16×b + 16×c ... = 16×(a+b+c+...)
An outlier is a point that is by itself of far from the rest of the points.
A cluster is a group of points that are very close together hence the cluster name.
sorry thats all i know
This is a terrible question. Send the publisher a nasty note.
First let's answer the question.
Cosine is adjacent over hypotenuse, so the cosine of the angle labeled 16 degrees is 24 (the adjacent side to 16 degrees) divided by 25 (the hypotenuse).
Answer: 24/25
---------
Now I'm going to complain about the question. 24/25 is of course 0.96 exactly, while
cos 16° ≈ 0.96126169593831886191649704855706487352569
They're not the same, and never think 24/25 is the cosine of 16 degrees. It's approximately the cosine of 16 degrees; there's a big difference.
The cosine of 16 degrees is some awfully complicated algebraic number, a zero of some high degree polynomial with integer coefficients. Worse yet, the angle whose cosine is 24/25 is almost certainly a transcendental number, not the zero of any such polynomial.
Trigonometry as practiced forces approximations to be employed. Let's not sweep that under the rug in the questions, please.
His final answer would be A. 0.0045
