-3^2= -(3)^2
The exponent of 2 only applies to the number 3. -(3)^2 should equal -9. This is true because according to the order of operations, exponents should be evaluated before multiplication. The negative sign here represents -1* 3^2.
If you want to find -3 to the power of 2 it must be written (-3)^2.
I believe the answer is 83.5 this may be wrong and if so I apologize in advance.
A ) The angle formed by 2 consecutive radii:
Ф= 360° : 8 = 45°
b ) The angle formed by a radius and a side of a polygon:
α = (180° - 45°): 2 = 135° : 2 = 67.5°
Answer:
B ) 45°, 67.5°

Answer:
The average rate of change = 4
Step-by-step explanation:
Given the function
x₁=-2, x₂=4
f(x₁) = f(-2) = 2x²-4 = 2(-2)²-4 = 8-4 = 4
f(x₂) = f(4) = 2x²-4 = 2(4)²-4 = 32-4 = 28
The average rate of change = f(x₂) - f(x₁) / x₂ - x₁
= (28-4)/(4-(-2))
= 24/6
= 4
Thus, the average rate of change = 4
