Start with x^2 + y^2 = r^2, where r signifies radius. Subst. 0 for x and 9 for y:
0^2 + 9^2 = r^2. Therefore, r = 9.
The std eqn is x^2 + y^2 = 9^2. this is a special case of
(x-h)^2 + (y-k)^2 = r^2 and is appropriate because the origin is at (0,0).
Answer:
Step-by-step explanation:
using the distributive property, the answer is -6.
Step-by-step explanation:
I need to use the fact that it has exactly one root to find the y part - do I use the quadratic formula on the last bit I have written?
I have x already and z = x+iy
Hi! I will try my best to answer your question, the wording provided is unclear.
If the 10% of the original cost of something is $1.50, then the total cost is $15.00.
Assuming this is the discounted price, which would be 90% of the original cost, the original cost would be $16.67.
