Answer:

a. $4,415.25

b. $4,376.70

c. 2.27986 years

Step-by-step explanation:

A = 4,000 (1 + 0.05/2)^(2 x 2)

= $4,415.25

A = 4,000 x e^(0.045 x 2)

= $4,376.70

c. $100 more than option 2 = 4,376.70 + 100

= $4,476.70

t (in years) = ln(4,476.70/4,000) / ln(1 + 0.05/2)

= 2.27986 years

Answer:

6/5 or 1.2, they're the same value

Step-by-step explanation:

When it says "rate of change", it's really just asking for the slope. If you don't know what the slope is, essentially how much the y-value increases by whenever x increases by 1. This can be formally defined using the equation: $\frac{y_2-y_1}{x_2-x_1}$ which is essentially $\frac{rise}{run}$ . The subtraction is finding the difference between the two numbers to see how much it's changed by. Btw the order doesn't matter, I could plug in (-3, -2) as (x2, y2) or I could plug it in as (x1, y1) as long as I make sure to input it in correctly. In this example I'll just say (-3, -2) = (x1, y1) and (2, 4) = (x2, y2). Plugging these values into the equation gives you: $\frac{4- (-2)}{2- (-3)} = \frac{6}{5}$ that's the rate of change
