Write the base four representation for 18 to 23 inclusive
seraphim [82]
\dfrac{18}4=4+\dfrac24

which means 18 can be divided by a higher power of 4 to get a quotient smaller than 4. Indeed,

\dfrac{18}{4^2}=\dfrac{18}{16}=1+\dfrac24

Now divide the remainder by 4 gives

\dfrac24=0+\dfrac24

and so

18_{10}=102_4

Now the next four numbers are easy to find.

19_{10}=103_4
20_{10}=110_4
21_{10}=111_4
22_{10}=112_4
23_{10}=113_4

Find the average rate of change from x = 3 to x = 15 for the function f(x) = 0.01(2)x
julsineya [31]
The average rate of change for this is the slope of the secant line that connects those 2 points (3, y) and (15, y).  What we need for the slope formula of change in y over change in x are the y values which are unknown as of right now. We can find them though! Don't worry! The equation is y = .01(2)^x. Using that equation, let's sub in both the 3 and the 15 and find the corresponding y values. Subbing in first a 3 gives you y = .01(2)^3, and y = .08.  Subbing in a 15 gives you y = .01(2)^15 and y = 327.68. Now we have the coordinates we need to find the slope of the secant line connecting those 2 points: (3, .08) and (15, 327.6). Fitting those into the slope formula gives us (327.68-.08)/(15-3). Simplifying that is 327.6/12 which divides out to 27.3

At the end of 8 years, Anna paid $400 interest for a loan. If the simple annual interest rate was 4%, how much did Anna borrow?
antiseptic1488 [7]

$1250

Use the formula i = prt

In this case, we don't know P or Principal amount

i = 400

r = .04 *found by diving 4/100*

n = 8

Set formula to solve for P like: P= i/r(n)

P=400/.04(8)

P= 400/.32

P = 1250
