Answer:
(f - g)(x) = x^4 - x^3 - 4x^2 - 3
Step-by-step explanation:
Subtract g(x)=x^3 + 3x^2 + 12 from f(x)= x^4 - x^2 + 9
First, take the negative of every term (including the label g(x) ) of g(x), obtaining -g(x) = -x^3 - 3x^2 - 12.
Now combine this result with f(x):
f(x)= x^4 - 0x^3 - x^2 + 9
-g(x) = - 1x^3 - 3x^2 - 12
---------------------------------------
(f - g)(x) = x^4 - x^3 - 4x^2 - 3
Answer:
a rule to know: a median divides the side into equal parts.
we know:
PR = -2a + 34
SR = 2a + 26
- based on the rule, SR is half of PR. in other words, PR is two times greater than SR.
so,
2SR = PR (now simply pluggin the expressions we have)
2(2a + 26) = -2a + 34 (solve the equation like any other equation prob.)
4a + 52 = -2a + 34
6a + 52 = 34
6a = -18
a = -3
- inorder to check if this is correct, simply reverse what we did. so pluggin the value of a to see if its correct.
The total mass for proton is -7.3 and the mass of the electron is 63.1. I'm sorry, I don't get the second part of the question.
Answer:
418122 seconds
Step-by-step explanation:
First divide 400,500 by 50. That is 8010.
Then multiple 8010 by 52.2 and you answer is 418122 seconds. OR
