Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt
Question
1 answer:
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
John gets a new job and receives a $800 signing bonus. After that, he makes $400 a day. [x = the number of days y = total earnings]
y = 400x + 800
[John earns $400 per day(x) plus a signing bonus(initial payment before working) of $800 = total amount of money he earns]
The slope is 400 or
The y-intercept is 800
