Answer:
z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2
Step-by-step explanation:
To complete the square, the last term has to be 1. So adding 10 to both sides, we get:
4z^2+4z+1 = 10
Since 4z^2+4z+1=(2z+1)^2,
(2z+1)^2 = 10.
Taking the square root of both sides, we get
2z+1=sqrt(10) or 2z+1=-sqrt(10)
So z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2
Answer:
<u><em>6% decline</em></u>
Step-by-step explanation:
<u>Original stock price</u> = $3.63 + $56.87 = $60.50
<u>Percentage decline</u> = 60.50 - 56.87 / 60.50
= 3.63 / 60.50
= 0.06
= <u><em>6% decline</em></u>
Answer:
Slope = 4
Step-by-step explanation:
Let R = total revenue the year before
R = 45,000 x 0.25 + 45,000
R = 11,250 + 45,000
R = $56,250
