Give the center, radius, and equation of the circle in the graph.

centre= (2,-3)

radius=2

equation= (x-2)^2+(y+3)^2= 4

Step-by-step explanation:

equation is found by the co-ordinates and the length of the radius

if the co-ordinates (2,-3)

x=2

y=-3

r= 2

so the equation will be like

=(x-2)^2+(y+3)^2=2^2

=(x-2)^2+(y+3)^2=4

Thankyou ^^

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
