Answer:

Step-by-step explanation:
To solve this problem, we can use the area of a circle formula:

<em>A = area</em>
<em>r = radius</em>
Lets plug the values into the equation:
Calculate 
Multiply
and 9 together

The area of the truck wheel is 
Area =bh
36in2=b(9)
——— ——
9 9
36
—— =4
9
Base= 4
Note that if

, then

, and so we can collapse the system of ODEs into a linear ODE:


which is a pretty standard linear ODE with constant coefficients. We have characteristic equation

so that the characteristic solution is

Now let's suppose the particular solution is

. Then

and so

Thus the general solution for

is

and you can find the solution

by simply differentiating

.
Seven tenths
Forty seven and nine tenths
Eighteen and eight one hundredths
One hundred twenty five and twenty three thousandths
One hundred and twenty six thousandths
One hundred fifty and seventy five thousandths
1) 0.07 zeros only matter if there is a non-zero digit, as well as the decimal to the left of it
2)90,000 it would have been 89000 if the 972 had been an 872
3).00420 must include the last zero, it is considered significant because of the reason in number one
