Answer:
30 minutes will it take to reach its specified operating temperature from 25°C.
Step-by-step explanation:
Initial Temperature of oven = 25°C
Time taken by oven to reach 85°C temperature = 15 minutes
We have to find time taken by oven to reach at temperature of 145°C
Increase in temperature in 15 minute = 85 - 25 = 60°C
So, Time take by oven to increase 60°C temperature = 15 min
Time take by oven to increase 1°C temperature = 
Temperature we have to increase = 145 - 25 = 120°C
Time take by oven to increase 120°C temperature = 
Therefore, 30 minutes will it take to reach its specified operating temperature from 25°C.
The answer is 2,652 because when you multiply 27 5/8 by 96 you get this answer
60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles
part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles
total is 180mi+140mi=320miles
Answer: 6w^3 - 16w^7
Explanation:
2w^3(3 - 8w^4)
= 6w^3 - 16w^7
Answer:
y = cos (2x + 2π) - 5/2
Step-by-step explanation:
y = a cos (bx + c) +d
a = Amplitude =1
period = 2π/b =π
b= 2
phase shift c/b = π
c/2 =π
c =2π
vertical translation = 5/2 units
d = -5/2 downwards
therefore substituting the values
y=1 cos (2x +2π) - 5/2
y = cos (2x + 2π) - 5/2 ;equation for the function
