Answer:
x = sqrt(10) - 9 or x = -9 - sqrt(10)
Step-by-step explanation by completing the square:
Solve for x:
x^2 + 18 x + 71 = 0
Subtract 71 from both sides:
x^2 + 18 x = -71
Add 81 to both sides:
x^2 + 18 x + 81 = 10
Write the left hand side as a square:
(x + 9)^2 = 10
Take the square root of both sides:
x + 9 = sqrt(10) or x + 9 = -sqrt(10)
Subtract 9 from both sides:
x = sqrt(10) - 9 or x + 9 = -sqrt(10)
Subtract 9 from both sides:
Answer: x = sqrt(10) - 9 or x = -9 - sqrt(10)
The answer is 3 because you multiply 5 and 1 which is 5 and you subtract 2 from the 5 which leaves you with 3.
Answer:
The amount at the end of second quarter is $1842.704
Step-by-step explanation:
Given as :
The principal in saving account = $1640
The rate of interest = 6 % compounded quarterly
The time period = 6 months
Now,<u> from compounded method</u>
The amount at the end of first quarter = 
= principal + 6 % of principal
I.e = $1640 + 6 % × $1640
Or, = $1640 + $ 98.4
∴ = $1738.4
Again ,
The amount at the end of second quarter = 
= 
+ 6 % of
I.e = $1738.4 + 6 % × $1738.4
Or, = $1738.4 + $104.304
∴ = $1842.704
So, The amount at the end of second quarter = = $1842.704
Hence , The amount at the end of second quarter is $1842.704 Answer
<span>Jack Watkins earns a base salary of $1500 a month, plus a 4% commission on the sales he makes. What is his gross pay of his sales for the month are $8000.
solution:
Gross pay=(salary)+(commissions)
base salary=$1500
commission=4%
monthly sales=$8000
commissions earned in cash
=4/100</span>×8000
=$320
thus
Gross salary=320+1500=$1820
