The expression (t*s)(x) may also be written as t(x)*s(x) which means that the functions are just multiply to each other. From the given,
                           t(x)*s(x) = (4x² - x + 3)(x - 7)
Thus, the answer for this item is letter D.

Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%

Hope it helps:-)

erastova [34]

Answer:

.15  million  dollars

Step-by-step explanation:

We know that the school district's income from property taxes were estimated at 1.4 million, but then we see that the actual income was 1.25 million.

To find the actual error, we must subtract 1.25 million 1.4 million.

1,400,000 - 1,250,000 =  150,000

150,000 thousand dollars or .15 million dollars.
