Answer:
The value of function at x = 2 is 8.
Step-by-step explanation:
Given : Function
We have to find the value of given function at x = 2 , that is f(2)
Consider the given function
To find the value f(2) put x = 2 in given function ,
We have,
Simplify, we have,
Simplify further, we have,
Thus, the value of function at x = 2 is 8.
I recommend using the Rational root theorem and finding the zeros through synthetic division. The first zero is x = 1, so the first factorization is (x-1). That leaves a remainder of x^2 -3x-10. Now try to factor that. That factors out to (x-5)(x+2) so the factors of that cubic are (x-1)(x-5)(x+2)
Answer:
13, -4
Step-by-step explanation:
If S is at 4, then for ST to = 8, you would add 8 to S, which you would get 13. You can also subtract 8 from S, which you would get -4.
Answer:
The temperature of the pan after 6 minutes = 40.96 ° c
Step-by-step explanation:
The temperature difference between a pan and room = 64 ° c
Temperature decreasing rate = 6 % per minute
Total temperature decrease in 6 minute = 64 × 0.06 × 6 = 23.04 ° c
The temperature of the pan after 6 minutes = 64 - 23.04 = 40.96 ° c
