Arrange your given equation to resembles the form
a^2 +2ab+ b^2 because this equals (a+b)^2
So we get:
y^2+16y+8^2=0
Now compare
y^2+16y+8^2 to a^2 +2ab+ b^2
So we got
y^2+2•8 y+8^2=0 which equals (y+8)^2
Answer:
$21 . 30
Step-by-step explanation:
Money spent on dinner =$ 63.90
Money paid by each of the 3 friends = 63.90 ÷ 3 = $ 21.30
Round 57.8 to 60 and round 81 to 80.
60/80 or, if you simplify it, 3/4
And it is common knowledge that 3/4 = .75
So the quotient of 57.8/81 is ~.75
Answer:
Step-by-step explanation:
A recipe for sabayon calls for 2 egg yolks, 3 tablespoons of sugar, and ¼ cup of white wine. After cracking the eggs, you start measuring the sugar, but accidentally put in 4 tablespoons of sugar. How can you compensate?
Note that we put in 4/3 more sugar than we wanted, because 3(4/3) = 4
So we need to increase eveything else by 4/3
So 2(4/3) = 8/3 = 2 +2/3 egg yolk and (1/4)(4/3) =4/12 = 1/3 cup of wine
Answer:
ln(125) ≈ 4.828314
Step-by-step explanation:
The relevant log relation is ...
log(a^b) = b·log(a)
__
This means your expression is equivalent to ...
3·ln(5) = ln(5^3) = ln(125) ≈ 4.828314
__
The "exact" answer is ln(125).
