1. The growth rate equation has a general form of:
y = A (r)^t
The function is growth when r≥1, and it is a decay when
r<1. Therefore:
y=200(0.5)^2t -->
Decay
y=1/2(2.5)^t/6 -->
Growth
y=(0.65)^t/4 -->
Decay
2. We rewrite the given equation (1/3)^d−5 = 81
Take the log of both sides:
(d – 5) log(1/3) = log 81
d – 5 = log 81 / log(1/3)
d – 5 = - 4
Multiply both sides by negative 1:
- d + 5 = 4
So the answer is D

Answer:
End points of the this segment are (9,1) and (2,3).
Step-by-step explanation:
The given function is
End points of the this segment are (1,9) and (3,2).
If a function is defined as
then
It means, we have to interchange x and y-coordinates of the end points.
So, end points of the this segment are (9,1) and (2,3).
Plot these point and join them by a line segment.
Answer:
x = -2
Step-by-step explanation:
3x + 2 = -2 + x Subtract x from both sides of the equation
2x + 2 = -2 Subtract 2 from both sides of the equation
2x = -4 Divide 2 from both sides of the equation
x = -2 <---- This is our answer
Hope it helped!
