Answer:
(-2.5, -10)
Step-by-step explanation:
Midpoint Formula: 
Step 1: Plug in
x = (-2 + -3)/2
y = (-8 + -12)/2
Step 2: Evaluate
x = -5/2
y = -20/2 = -10
Step 3: Format into coordinates
(-5/2, -10)
Step 4: Convert to decimal
(-2.5, -10)
The axis of symmetry of the quadratic equation y = 2x^2 + 3 is x = 0
<h3>How to determine the axis of symmetry?</h3>
The equation is given as:
y = 2x^2 + 3
Differentiate the above equation with respect to x
y' = 4x + 0
This gives
y' = 4x
Set the equation to 0
4x = 0
Divide both sides by 4
x = 0
Hence, the axis of symmetry is x = 0

Answer:
212 student tickets
Step-by-step explanation:
I am assuming that this is what you meant:
Total of tickets sold= 326
Price of an adult ticket= $8
Price of a student ticket= $5
Total amount if money (student & adult) collected= $1972

Answer:
The answer is 18,900 Joules.
Step-by-step explanation:
If you work out the equation
Half of 350 is 175
12 squared is 144
6 squared is 36
Subtract 36 from 144 and get 108
108 multiplied by 175 is 18,900
