Answer:
58+40e−t/2458+40e−t/24
step by step explanation:
Normally, the temperature of a corpse is the temperature of the surrounding environment.
This is done by losing or gaining heat to equilibrate to that of the surrounding.
Let's assume that the final temperature of the corpse is after t hrs.
Then the temperature of the surrounding in degree Fahrenheit is equal to 58+40e−t/2458+40e−t/24
Answer:
A)15x+30=weekly income
B)8 hours
Step-by-step explanation:
15x+30= weekly income
The 15 multiplies because it says per hour
The 30 is constant because she only earns it once (per week)
15x+30=150
minus 30 from both sides
15x=120
divide by 15
x=8
Answer:
22 for num 5
Step-by-step explanation:
Step-by-step explanation:
log <base a> b = x
means
a^x = b
So
3^2 = x^2+7x+21
x^2 + 7x + 21 - 9 = 0
x^2 + 7x + 12 = 0
(x+3)(x+4)
x = -3 or -4
