Let the sides of the triangle be a, b, 10 where a \leq b < 10
By the triangle inequality,
a + b > 10
\implies a + b + 10 > 20
ie\,\, P > 20
\implies \boxed{(C),\, (D)}
So there are three parts to this question. Firstly you must find the point C, then find the equation of the line BC, then use the perpendicular distance formula. Note that it says that ABCO is a parallelogram. This means that AO is the 'same' as BC.
To get from A to O you must go 2 units to...
There are 2 ways to show that the approximation underestimates the integral. Firstly you could differentiate the function and show that it is concave down for the domain from 0 to 2. Or you could graph the logarithmic function and mearly show that its concave down for the aforementioned domain...
Im going to start a bachelor of Psychology next year and a bachelor of Mathematics the year after and when i finish high school i will go on to doing a doctorate in mathematics/ theoretical physics.
To find out just grab the nearest "General Relativity" book and read it. But you would first have to read up on tensor calculus, geodesics, manifolds, and a little topology just to get a basic understanding of the derivation of this formula.
This is absolutely ridiculous, i might miss out on a state rank just because i had the flu when i was doing my trial, and i will now miss out on a state rank because of it (most likely) =(
So basically what you are saying is even if i get 100% in the HSC mathematics exam, whether or not i get a state rank depends on how well the no. 1 person goes?
