The Celsius temperature, C, of a chemical reaction increases and then decreases over time according to the
1 answer:
Answer:
See explanations below
Step-by-step explanation:
Given the quadratic formula that expresses the temperature of a chemical reaction
C(t)=-12t² +8t +93
Given that C(t) = 110°, we are to find the value of t
Substitute
110 = -12t² +8t +93
-12t² +8t +93-110 = 0
-12t² +8t -17 = 0
12t² -8t + 17 = 0
Using the general formula;
t = -(-8)±√(-8)²-4(12)(17)/2(12)
t = 8±√64-816/24
t = 8±√-752/24
<em>Since the value of t will give a complex number, hence the time doesn't exist when the reaction reaches 110°C</em>

The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the Sun :D
The answer to your question is y = sin(x + 90) as we have a sine graph phase shifted 90 units left
