Newton's cooling model is ΔT = ΔTo * e ^ (-k t)
ΔTo = 200°F - 70°F = 130°F
k = 0.6
t = 2 hours
=> ΔT = 130 * e ^ (-0.6 t) = 130 * e^ (-0.6 * 2) = 130 * e ^ (-1.2)
ΔT = 39.15°F
ΔT = T - Tenvironment => T = ΔT + Tenvironment = 39.15°F + 70°F = 109.15°F ≈ 109 °F.
Answer: T = 109 °F
Answer:
FIFTY - FIVE THOUSAND FIVE HUNDRED AND FIFTY-FIVE
Step-by-step explanation:
Answer:
3 to 9
second is 2.5 to 15
Step-by-step explanation:
Answer:
n = 3
Step-by-step explanation:
Ratio from Triangle A to Triangle B is 2:1.
n+2 = 5
n = 3
5 and 4 are two in inequalities because they make 5 bigger then 13
