(a-b)
Step-by-step explanation:
a minus b whole square minus C square
Answer:
0.25D^2 π in^2.
Step-by-step explanation:
The cross section is a circle of diameter D inches, so its radius is 0.5D inches.
The area of cross section is πr^2
= (0.5D)^2 π
= 0.25D^2 π in^2.
N= - 31 over 19
alternative form
n= -1 12 over19 , n ~ - 1.63158
No greater, so max is -12
in 10 seconds
-12 times 10=-120
-120=-120
it can reach it if it goes max speed
but it says, inless than 10 seconds
it requires at least 10 seconds to reach the cave, so it CANNOT reach it in less than 10 seconds
no
I believe the answer is sometimes. The most well known Pythagorean triple is 3,4,5.
3^2+4^2=5^2
9+16=25
25=25
However this is not always the case, for example,
8,15,17
is also a Pythagorean triple, but has no positive, consecutive, integers.
