opposite means the sign changes (from positive to negative or vice versa)
since a rational number includes both positives and negatives, then the opposite of a rational is also a rational.
For example:
is a rational number. Its opposite is
, which is also a rational number.
Hope this helped!
Answer: YES
Answer:
It's the law of cosines
Step-by-step explanation:
law of cosines states that ![c^{2} =a^{2} +b^{2} -2ab (cos(\alpha ))](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D%20-2ab%20%28cos%28%5Calpha%20%29%29)
so we know that a = 7, b = 4, and alpha would be 135 degrees, so just plugging it in gets us 49+16-2*7*4*(-0.707) = 65 + 39.59 = 104.59
First row -11, -28, -8,16, -36
Answer:
{4}
Step-by-step explanation:
first move 7 to RHS in addition
then 4 in RHS in division
Principal amount is $1510, so P = 1,760 dollars.
Compounding period is daily, so N = 365.
Interest rate is 6%, so r = 0.06
Time of investment is 7 years, so t = 7 years.
We can use compound interest formula as given below :-
Amount =
Hence, total amount in account would be 2,678.56 dollars.
