Answer:
<u>j = 2.5s</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Lemon juice (mL) Sugar (gr)
Batch A 500 200
Batch B 750 300
Batch C 1,500 600
2. Write an equation to describe the relationship between j, the amount of lemon juice in mL, and s, the amount of sugar in g.
Ratio = Amount of lemon juice/Amount of sugar
Ratio = 500/200 = 750/300 = 1,500/600
Ratio = 2.5
Now, we can write the equation, this way:
<u>j = 2.5s</u>
June :
900 + 0.02(48,500) + 0.018(48500 - 17500) =
900 + 970 + 558 = 2428 <==
July :
900 + .02(50,200) + 0.018(50200 - 17500) =
900 + 1004 + 588.60 = 2492.60 <===
Cos ( ∠C ) = 5/13 = 0.38462
m ∠C = cos^(-1) 0.38642 = 67.4°
m ∠A = 90° - 67.4° = 22.6°
m ∠C - m ∠A = 67.4° - 22.6° = 44.8°
Answer:
B ) 44.8°
Answer:
1. Equilibrium solution: y= -3
2. Equilibrium solution y= ±1.414
Step-by-step explanation:
Thinking process:
The equilibrium solution can only be derived when 
1. Let's look at the first equation:

equating
to the expression
gives
y + 3 = 0
y = -3
Therefore, the equilibrium solution occurs at y = -3
2. Let's look at the second solution:

dividing each side by (t²-1) gives
1/(t²-1)
= (y²-2)/ (y²-4)
factorizing the right hand side gives:
at equilibrium:
, then
y² - 2 = 0
solving for y gives y = ±√2
= ±1.414
