Answer:

Step-by-step explanation:
By definition, the tangent of a z-angle is defined as

For this case



So



Answer:
b = 0.7
Step-by-step explanation:
to solve the equation, you must isolate "b" so the variable is by itself,,
to do this, divide both sides of the equation by 8:
8b = 5.6
b = 5.6/8
now, simply divide 5.6 by 8 to get your answer,,
b = 5.6/8
b = 0.7
y = a(1-r)^×

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:
cool
Step-by-step explanation:
yo hi guys i'm African american
-1 = 3x - 7
Add +7 to each side
6 = 3x
Divide each side by 3
X = 2
f(-1) = 3 * 2 - 7
