Step-by-step explanation:
2x^2-2x+8x-8
2x(x-1)+8(x-1)
(2x+8)(x-1)
x=-4 x=1
Answer:
The temperature rose by 5 degrees celcius between 11 am and 4 pm
Step-by-step explanation:
Here in this question, we want to find the integer which represents the temperature change from 11 am to 4 pm.
Initially, in the morning, the temperature was -2 . By 11, it had decreased by 3 degrees. What this means is that the temperature went down further by 3 degrees.
Mathematically, the temperature at 11 will be -2-3 = -5 degrees celcius
Now at 4 pm, the temperature went from -5 to 0 degrees.
The temperature change between 11 am and 4 pm will be; 0-(-5) = 0 + 5 = 5 degrees celcius
This means that the temperature rose by 5 degrees celcius between 11 am and 4 pm
Answer:
Step-by-step explanation:
Given,
Time taken in one rotation of earth = 23 hours, 56 minutes and 4 seconds.
Since, 1 minute = 60 seconds and 1 hour = 3600 seconds,
⇒ Time taken in one rotation of earth = (23 × 3600 + 56 × 60 + 4) seconds
= 86164 seconds,
Now, the number of radians in one rotation = 2π,
That is, 86164 seconds = 2π radians
Hence, the number of radians in one second is
