Answer:
About 30 min.
Step-by-step explanation:
Since it takes 10 min to walk a half of mile, it will take 20 min to walk a whole mile.
Since we will be walking one and a half miles, it should take about 30 minutes.
Hope this helps.
Answer:
A. -4
Step-by-step explanation:
replace x with 2 in the function:
f(2) = 4×2 - 12 ➡ 8 - 12 = -4
Answer:
15.47
Step-by-step explanation:
Since the four is in the hundrenths place you use the digit to the right of it, and if the number is greater than 5 you add one more. Thus the answer being 15.47
First find the characteristic solution. The characteristic equation is

which as one root at

of multiplicity 2. This means the characteristic solution for this ODE is

For the nonhomogeneous part, you can try a particular solution of the form

which has derivatives


Substituting into the ODE, the left hand side reduces significantly to

and it follows that

Therefore the particular solution is

and so the general solution is the sum of the characteristic and particular solutions,

Not entirely sure, but it seem the answer could be B.) It will not be spread out vertically across the entire coordinate plane because in step 5, Nancy selected an incorrect scale on the y-axis.
