Answer:
10
Step-by-step explanation:
Because 6+4 is 10. When u do these look at the number u know and add them together to get the first number
There are three things you have to know:
- A function is convex when its second derivative
- A function is concave when it second derivative
- The derivative of a power,
, is 
So, the first derivative is
and the second derivative is
This implies that the second derivative of a parabola is constant, and of course that 2 doesn't change the sign of 
.

Answer:
No The correct Answer is "G"
Step-by-step explanation:
First lets find 300% as a number which is 3 ok so now
increase 10 by 300%
so 100%+300%=400%
and half of 400 which is 200%
so H is no correct g is
This is a distance problem so we can use distance = rate x time.
Given: the distance to the telephone is the same as the distance back from the telephone. We also know the two speeds and the total time for the trip.
But first let's convert 15 minutes into seconds: 15*60 = 900 seconds.
So: d = 5(t1) (t1 is the time he took to run to the telephone)
d = 4(t2) (t2 is the time he took to come back from the telephone
t1 + t2 = 900 or t1 = 900 - t2
Now use substitution:
5t1 = 4t2
5*(900 - t2) = 4t2
4500 - 5t2 = 4t2
4500 = 9t2
500 = t2
So therefore t1 = 400
So the distance to the telephone is 5*400 = 2000 meters
