Step-by-step explanation:
Heavy Metal "music" impacts negatively the long term memory, if at least the ability to access it.
while harmonic music has no blocking effect or maybe even strengthens the long term memory and the ability to access it.
here 3 remarks.
first 2 scientifically from psychology : memory works mostly associative. that means brains do not store absolute information like a digital computer, but always in combination and association with other pieces of information. if there is nothing else to remember (like a more or less random pattern of sound effects for that the brain cannot find a rule or concept for), there are no associations with presented pieces of information, and the storage and access to it is much harder and restricted.
and - loud crashing and seemingly random noise triggers the panic mode in our brains. and panic is the mode favoring pure instinct and suppressing cognitive functions.
and finally, personally, it just confirms what I literally feel when listening to such music : it destroys at that moment any ability to keep a straight thought, prolonged exposure gives me the feeling that something gets broken inside my brain and thought processes.
I suspect that this is exactly the feeling that the fans of this kind of music are after (kind of like most drugs), but I am not surprised that there actually is something broken in the brain (again, as with drugs).
We know that
in the triangle ROA
tan (∡ROA)=12/5
(∡ROA)=arc tan(12/5)---------> 67.38°
in the triangle OPA
(∡POA)=(∡ROA)-------> 67.38°
sin (∡POA)=PA/5-------> PA=5*sin (67.38°)-----> 4.62 units
the answer is
PA=4.62 units
<span>alternative method
</span>in the triangle ROA
RO²=12²+5²-------> RO=13 units
sin (∡ROA)=12/13
in the triangle OPA
(∡POA)=(∡ROA)
sin (∡POA)=12/13
sin (∡POA)=PA/5
12/13=PA/5-------> PA=12*5/13-------> PA=4.62 units
Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons.
Answer:rectangular pyramid
Explanation:1- rectangular pyramid:A rectangular pyramid has only one base that has a rectangle shape. Slanting sides meet at a vertex in the top.
2- Heptagonal prism:A prism whose two bases are heptagons (7-sided polygons). The two bases are parallel and congruent
3- Cylinder:A prism whose two bases are circles. The two bases are parallel and congruent
4- Cube:A prism whose two bases are squares. The two bases are parallel and congruent
I have attached figures of the all 4 options for better illustration.
Answer:
Step-by-step explanation:
Give an example of a proportion using only numbers.
When all numbers are given (A, B, C, D) in order to assess whether the proportion is true or false it will calculate the value of the division of A by B (A/B), and the value of the division of C by D then compares it. If the two resulting values are equal then the ratio is TRUE, otherwise is FALSE. Few examples of calculations 1.
How do you know it is a proportion?
A proportion is just an expression setting two ratios equal to each other, using different absolute numbers in the fractions. Proportions are written like ratios are, for example, a/b = c/d or a:b = c:d. You don't need a fancy ratio calculator function to solve most simple ratio problems.
