Answer:
A) 288.62
Step-by-step explanation:
10.4×15.3= 159.12
10.4²+15.3²= X²
342.25= X²
18.5= X
7×18.5= 129.5
129.5+159.12= 288.62
Answer:
Step-by-step explanation:
We know by definition that the cosine is an even function, therefore
We also know that the sin is an odd function, therefore
By definition:
Then:
Using these trigonometric properties we can simplify the expression

21 = 3*7
65 = 5*13
CGF: to find the greatest common factor, multiply those factors both numbers have in common
GCF :1 since there are no factors in common
Answer:
2.6768·10^(-14) (Answer C)
Step-by-step explanation:
Problem 4: We ADD the powers of 10: 10^6·10^(-3) = 10^3. Also, 3.6·1.7 = 6.12. Therefore, Answer D is correct.
Problem 5: Again we ADD (combine) the powers of 10: 10^(-10)·10^(-5) =
10^(-15). 4.78·5.6 = 26.768. Our intermediary answer is thus:
26.768·10^(-15). This must be rewritten in the form x.xxxx, so here we have:
2.6768·10^(-14) (Answer C)
