Answer:
Step-by-step explanation:
You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:
and solving for a:
so
a = 143.0
1) f(x) + g(x)
= 7√x + 4 + 2√x - 2
= √x(7 + 2) + 2
= 9√x + 2 [ Final Answer ]
2) f(x) - g(x)
= 7√x + 4 - (2√x - 2)
= 7√x + 4 - 2√x + 2
= √x(7 - 2) + 6
= 5√x + 6 [ Final Answer ]
Hope this helps!
Since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom.
Answer:
= 7034000000000
(real number)
= 7.034 × 1012
(scientific notation)
= 7.034e12
(scientific e notation)
= 7.034 × 1012
(engineering notation)
(trillion; prefix tera- (T))
= 7034000000000
(real number)
Step-by-step explanation:
Convert Scientific Notation to a Real Number
Multiply the decimal number by 10 raised to the power indicated.
Examples:
3.456 x 10^4 = 3.456 x 10,000 = 34560
3.456 x 10^-4 = 3.456 x .0001 = 0.0003456
