y = a(1-r)^×
source: https://mathbitsnotebook.com/Algebra2/Exponential/EXGrowthDecay.html
y = exponential decay
a = initial amount = 78000
r = decay rate = .03
x = number of time intervals = w
Error:
b = growth/ decay factor
b = 1+r for growth
b = 1-r for decay
x = w per the above information
Sarah did not account for either of these points when creating her equation.
Correct solution:
y = 78000 (1-.03)^w
Answer:
90° CCW
Step-by-step explanation:
The angle from C to the origin to C' is a right angle when measured counterclockwise (in the usual direction).
ΔA'B'C' is a rotation of ΔABC 90° CCW.
__
This is fully equivalent to a rotation of 270° CW.
Answer:
m/_2 = 127°
m/_4 = 127°
m/_1 = 53°
m/_3 = 53°
Step-by-step explanation:
angle 2 and 4 are the same in the diagram.
to get angle 1 and 3 i did:
127°×2°=254°
360°-254°=106°
106°÷2°=53°
Answer:
The answer would be 6.32
