So we know the focus and deritrix, so plug it into the distance formula

Square root all (x - 1)^2 (y- 3)^2 = (x + 5)^2 just do some algebra you will get x^2 -2x + 1 + y^2 - 6y + 9 = x^2 + 10x + 25, simplified you will get -12x - 15 = 6y - y^2. I’m pretty sure the answer is c

In both cases, the money paid is called the interest. It is usually expressed as a percent. Here we shall look at a formula for simple interest.

My last function question. Please break this down for me. Brainliest answer will be given
cupoosta [38]
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
