Answer:
95 m
Step-by-step explanation:
If the graph shows the height of the balloon after t minutes from beginning of descent, look to when t = 0. At t=0 it has not yet begun it's descent because no minutes have passed. At that point on the graph the height is 95 m (the point is (0,95))
Here's the given:
P=$400
i=7.5%
A=$8500
The formula used for this problem is:
A = P(1+i)^t
Manipulating the equation to arrive at t, we have:
t = ln(A/P) / ln(1+i)
Plugging in values:
t = ln($8500/$400) / ln(1+0.075)

B-8. This is because -4 to 0 is 4 and then 0-4 is 4. 4+4=8
Answer:
-6
Step-by-step explanation:
substitute for x and y in the given equation
x=0
y=-6
let the unknown number be 'b'
y = -4x + b
-6 = 4*0 + b
b = -6
