Step-by-step explanation:

So technically, your replacing the x, with -8, 4, 12, 20. So bassically it would be 2*-8, 2*4, 2*12, 2*20. And those answers you get will get you, your range, so 2*-8 would be -16, 2*4= 8, 2*12=24, 2*20=40

So your ranges would be, -16, 8, 24 and 40.

Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%
gizmo_the_mogwai [7]

Answer:

Step-by-step explanation

Note that

Interest is represented by I=1326

The principal is represented by P=47,600

Rate is R =4%

And Time is year

Interest is calculated using the formulae,

I =PRT/100

From the above formulae, time can be calculated as

T=100I/PR

T= 100×1326/(47600×4)

T= 132600/190400

T= 0.6964 years

To convert to days, multiply by 365(since those no of days make a year)

T= 0.6964×365=254 days

This was approximated to the nearest day

Answer is 254 days

Write the equation for an exponential function that triples ever year, x, when the original amount is 4.
Citrus2011 [14]

Answer:

y = 4(3)^x

Step-by-step explanation:

Here, we want to write the exponential equation

From the question, we have the equation tripling in x value every year and the original amount is 4

The exponential equation is of the form;

y = a(b)^n

In this case;

a = 4 , b = 3 and n = x

So we have the equation as;

y = 4(3)^x
