Answer
x= -7, -1
Step-by-step explanation:
x^2= -7x- 8
x^2+ 7x+ 8 =0
x+7=0 x+1=0
x=-7 x=-1
4.16161616=41010101/6250000
Showing the work
Rewrite the decimal number as a fraction with 1 in the denominator
4.16161616=4.16161616/1
Multiply to remove 8 decimal places. Here, you multiply top and bottom by 10^8 = 100000000
4.16161616/1×100000000/100000000=416161616/100000000
Find the Greatest Common Factor (GCF) of 416161616 and 100000000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 16,
416161616÷16/100000000÷16=26010101/6250000
Simplify the improper fraction,
=4 1010101/6250000
In conclusion,
4.16161616=4 1010101/6250000

Answer:
$280.51
Step-by-step explanation:
F= 200(1 + 07)^5
The future worth (F) of the investment at present (P) with a compound interest i after n years is calculated through the equation, F=P x (1 + i)^n
To round off a given number in decimals to one decimal place (1 dp), we simply take the figure right after the decimal and approximate the remaining after it. If the second number after the decimal is a significant number (5 and above) we make it 1 and add to the number right after the decimal. If its NOT a significant number, we simply disregard it. The solutions therefore are;
ANSWER:
Notice how the number in (1) becomes 0.7, after taking the next number (which is 9) and adding it as 1 to the number after the decimal (which is 6). The same applies to the number in (3).
