Answer:
Step-by-step explanation:
10y2 - 17y + 12 = y + 16
10y2 - 17y + 12 - 16 = y
10y2 - 17y - 4 = y
10y2 -17y - y -4 = 0
10y2 -16y - 4 = 0
Now put formula
x = -b +- (square root) b2 - 4ac
2a
a = 10 b= -16 c= -4
y = -(-16) +- (square root) -16 - 4 (10) (-4)
2(10)
y = 16 +- (square root) -16 - 400
20
y = 16 +- (square root) -416
20
y = 16 +- 20.396
20
Now this +- is the plus minus thingy in which two answers come
The first we will do is +
16 + 20.396 16 - 20.396
20 20
= 1.8198 = -0.2198
well the name of the phase for that is called freezing. I think that's we have to look for, maybe not, but I hope I helped
Step-by-step explanation:
the similarity of the triangle:
x/18 = 8/12
=> 12x = 18×8
12x = 144
x = 12
Answer:
Step-by-step explanation:
For this case we have the following data:
Days to Maturity Dollar Value $ Millions)
20 20
12 30
7 10
5 15
6 10
For this case the definition of weigthed mean is given by:
Where 
represent the weight of each value and 
represent the observations (Days to maturity)
Our interest is the number of days so then our weighting variable would be the dollar Value, so then we can find the weighted mean like this:
