There both 4 and there are the 4th number
Answer:
Step-by-step explanation:
given,
radius of sphere = 3
volume of cone:
r is the radius of circular base
h is the height of the cone
here r = x and h = 3 + y
now, volume in term of x and y
Applying Pythagoras theorem
x² + y² = 3²
differentiating both side
for maxima 
y² + 2 y - 3 = 0
(y+3)(y-1)=0
y = 1,-3
y cannot be negative so, volume at y = 1
Hence, the largest cone which can be inscribed in the spheres of the radius 3 has volume
Answer: A
Step-by-step explanation:
The base determines it, as if the base is less than 1, it is decreasing, and if its greater than 1, it increases
Answer:
4. 8 5/12
Step-by-step explanation:
4 2/3 + 3 3/4 =
= 4 + 2/3 + 3 + 3/4
= 4 + 3 + 8/12 + 9/12
= 7 + 17/12
= 7 + 12/12 + 5/12
= 7 + 1 + 5/12
= 8 5/12
Answer:
$557.51
Step-by-step explanation:
A financial calculator tells you the payments are ...
on $80,000 at 4.75%: $417.32
on $20,000 at 7.525%: $140.19
Then the total monthly payment is ...
$417.32 +140.19 = $557.51
_____
You can use the amortization formula to find the payment (A) on principal P at interest rate r for t years to be ...
A = P(r/12)/(1 -(1+r/12)^(-12t))
I find it takes fewer keystrokes to enter the numbers into a financial calculator. Both give the same result.
