Answer:

B

Step-by-step explanation:

The y-axis shows the number of gallons of water left (with respect to time).

The x-axis shows the time.

Domain is the set of x-values that is allowed. Looking at the graph, we see that the water drains within 0 to 12 minutes. After 12 minutes there is no water left, so that's not feasible. Hence, the domain would be from 0 to 12.

Looking at the choices, that is B, 0 ≤ x ≤ 12

A function has y-intercept of -2 and a slope of -1. which equation below describes the function?
ozzi
The correct equation should look something like this:
y= -1x - 2

Consider the equation for a line:
y = mx + b,
Where ‘m’ is the slope
Where ‘b’ is the y-intercept.

From there you can plug in your known values for ‘m’ and ‘b’, and get the equation above. If you are still not convinced, I suggest you graph the function and observe its slope and y-intercept.

Hope this helps!

You have $380,000
lesantik [10]

Answer:

If the capitalization method is continuous, the interest obtained will be $104986.99

Step-by-step explanation:

Cn = Co * (1 + i)^n

Co = 380,000

i = 0.05

n = 5

So:

Cn =380,000 * (1+.05/1)^(1*5)

Cn = 380,000 * (1+.05)^5

Cn = 380,000 * (105)^5

Cn = 380,000 * (1.2763)

Cn = 484,986.99

Cn - Co = interest acumulated:

484,986.99-380,000 = $104986.99
