Answer:
(x +2)^2 + (y +2)^2 = .5625
Step-by-step explanation:
(x - h)^2 + (y - k)^2 = r^2
(x + 2)^2 + (y + 2)^2 = .75^2
2n+9+5n=30 combine like terms on left side
7n+9=30 subtract 9 from both sides
7n=21 divide both sides by 7
n=3
Im not exactly sure but i think:
r^2+6r+2
________
5r^2-5r-25
remember IM NOT SO SURE
Answer: is that a high school math it looks hard to me
Step-by-step explanation??
Ts temperature as a function of time is given by T(t)=a(1-e^kt)+b
the values of a and b area = 50 Fb = 350 F
this is very evident to equation the b is the initial temperatre of the oven which is 350 F
and also a is the initial temperature of the potato because it is the term multiplied by the exponent term which will indicate the temperature increasse of the potato
