kiruha [24]3 years ago

Answer:

4.432432 * 10^(13)

Step-by-step explanation:

We need to divide

(1.64 x10^(-24))

---------------------

(3.7  x10^(-38))

We can first divide (1.64/3.7)

0.4432432  *   (10^(-24))

                        ---------------------

                        (10^(-38))

Since the term consists of a division with the same base, we just need to subtract the exponents

0.4432432  *   (10^(-24 - (-38)))

= 0.4432432  * 10^(-24 +38)

= 0.4432432 * 10^(14)

= 4.432432 * 10^(13)

If f(x) = [x] - 5, what is (86)?
tatuchka [14]

Answer:

81

Step-by-step explanation:

I am assuming that you are asking what is [x] - 5 if f(86).

When you have this kind of question, what you do is to substitute the variable inside the parenthesis, so like what is says, f(x). If the question replaces the variable x with 86, that means you input the number into the equation.

So [x] - 5, if f(86).

Substitute:

86 - 5

On a test, wrong answers are worth -5.25 points and right answers are worth 3.5 points. So far, Marshall has one right answer an
slamgirl [31]

Answer:

-5.25 + 3.5 = -1.75

Step-by-step explanation:

This can technically be done two ways. The first is the most simplified, and the second less simplified, and less likely to get the best grade.

1.So long as you don't have to order it chronologically, you should be good with this one: -5.25+3.5=-1.75

2.This one IS chronological (she got a correct answer, then a wrong answer), but you can NOT simplify it, because it asks for an addition equation: 3.5+(-5.25)=-1.75

The best option is probably #1

Triangle can be formed with angle measures of 32 degrees, 126 degrees, and 32 degrees
Alexus [3.1K]

Answer:

No triangle can be formed with these angles.

Step-by-step explanation:

There must be  180 degrees in a triangle.

32 + 126 + 32

= 126 + 64

= 190 degrees - so this cannot form a triangle.
