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
the the negative angle is -(2π-π/4)= -\frac{7 \pi }{4}
Well, don't you already have the t value ,-7.
Answer:
3
Step-by-step explanation:
Slope of a line parallel to y = 3x + 5 is equal to 3.
