Use the formula for the volume of a triangular pyramid: V=13Ah , where A = area of the triangular base, and H = height of the pyramid.
Answer:
π/8
Step-by-step explanation:
∫₂°° dx / (4 + x²)
If x = 2 tan u, then dx = 2 sec²u du.
When u = π/4, x = 2. As u approaches π/2, x approaches ∞.
∫ (2 sec²u du) / (4 + 4 tan²u)
½ ∫ (sec²u du) / (1 + tan²u)
½ ∫ (sec²u du) / sec²u
½ ∫ du
½ (π/2 − π/4)
π/8
Legally speaking? No. When you go to the bank to open up an account, you need a birth certificate, social security card, etc. There's a process to it. Many banks will not allow you to open an account without your needed information, even if they do know you personally (my mom worked at a bank...)
Answer:
b)
Step-by-step explanation:
<u>Step(i)</u>:-
Given quadratic equation ax² + bx + c = 0
<u>step(ii)</u>:-
ax² + bx = -c
<u>Step(iii):</u>-
Dividing 'a' on both sides , we get
<u><em>Step(iv)</em></u>:-
Adding 
on both sides , we get
