64 is the answer to the question above
Answer:
210°F
110 minutes
Step-by-step explanation:
Given that :
Temperature of cake t minutes after being removed from oven :
f(x)=70+140e^-0.024t
Temperature T the timee it is removed ;
At this point, the time t = 0
f(t)=70+140e^-0.024t
f(x)=70+140e^-0.024(0)
= 70 + 140(1)
= 210°F
how long will it take for the cake to reach a temperature of 80oF
80 = 70+140e^-0.024t
80 - 70 = 140*e^-0.024t
10/140 = e^-0.024t
0.0714285 = e^-0.024t
In(0.0714285) = - 0.024t
−2.639057 = - 0.024t
t = 2.639057 / 0.024
t = 109.9607
t = 110 minutes
9.) Given that the salesperson earns a base salary of $4000 per month plus 15% commission on sales if the salesperson's commission is lowered to 5%, then <span>her monthly income g(s) is given by the function g(s)=4000 +0.05s where s is monthly sales in dollars
10) </span>Given that the salesperson earns a base salary of $4000 per month plus 15% commission on sales if the salesperson's base salary is doubled, then her monthly income h(s) is given by the function g(s)=8000 +0.15s where s is monthly sales in dollars
11) Given that the salesperson earns a base salary of $4000 per month plus 15% commission on sales <span>if the salesperson's base salary is cut in half and her commission is doubled</span>, then her monthly income k(s) is given by the function k(s)=2000 +0.3s where s is monthly sales in dollars.
