The First One Answer is
x•(1+xy+x^2y)
Answer:
Volume = 35185.8 
Step-by-step explanation:
Recall the formula for the volume of a cone: 
Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)
And h stands for the height of the cone (in your case 21 km)
We replace such in the formula and calculate its final value:
We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:
Volume = 35185.8
Answer:
18x+y=-52
Step-by-step explanation:
we all know and love(being 100% sarcastic here)the standard form as
ax+by=c
y=-9(x+3)*2+2----This is weird and not so nice
so lets make it nice by distributing the 9::::
y=(-9x-27)2+2
and now the 2:
y=-18x-54+2
y=-18x-52
oops this is NOT in S.F we got to switch the -52 and y
52=-18x-y
-18 cant be neg. so we have to divide by -1 on both sides
-52=18x+y
18x+y=-52

Answer:
Step-by-step explanation:
First find the number of liters needed to go 12500 km
Fuel = 12500 km * (8.85 L / 100 km)
Fuel = 1106.25 Liters
Now that we know the number of liters we need, we can find the cost.
1106.25 L * 158 c / L
174787.5 cents.
I fear going any further because I don't know where you reside. If you live in a place where they have dollars, then you can divide by 100 to get the dollar amount
1747875 / 100 = 1747,88 dollars
