1st
I need to find out what percentage is left after 1 minute
100 - 5.7 = 94.3% (0.943)

2nd plug into the formula A =  A_{0}  r^{t}

A0 = 310
r = 0.943
t = 9

A = 310(0.943)^{9} \\ A = 310(0.58966) \\ A = 182.8 g

NEED HELP ASAP Which of the following equations describe the line shown below?
bagirrra123 [75]
(-1,6)(2,-6)
slope = (-6 - 6) / (2 - (-1) = -12/3 = -4

y = mx + b
slope(m) = -4
(-1,6)...x = -1 and y = 6
sub and find b, the y int
6 = -4(-1) + b
6 = 4 + b
6 - 4 = b
2 = b

so the equation is : y = -4x + 2 <=== here is one

y - y1 = m(x - x1)
slope(m) = -4
(-1,6)...x1 = -1 and y1 = 6
sub
y - 6 = -4(x - (-1) =
y - 6 = -4(x + 1) <=== here is one

y - y1 = m(x - x1)
slope(m) = -4
(2,- 6)...x1 = 2 and y1 = - 6
sub
y - (-6) = -4(x - 2) =
y + 6 = -4(x - 2) .... here is one, but it is not an answer choice
