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

Question 1: x-intercept is: 2; y-intercept is: -5
Part A: x-intercept is: 30; y-intercept is: 45
Part B: In the context of the necklace and bracelet chain purchases, the best interpretation of the x-intercept is: B. If Chloe purchases 30 necklace chains, then she can purchase 0 bracelet chains.
<h3>What is the X-intercept and Y-intercept of a Function?</h3>
The x-intercept is the point on the x-axis, where the line intercepts the x-axis. At this point, the corresponding value of y is usually zero (0).
On the other hand, the y-intercept is the point on the y-axis, where the line intercepts the y-axis. At this point, the corresponding value of x is usually 0.
