Answer:
Step-by-step explanation:
We are asked to find (f+g)(x). The question is essentially asking us to find the sum of f(x) and g(x).
We know that f(x) equals 3x-1 and g(x) equals x+2. Substitute the values of the functions in.
Combine the like terms.
- 3x and x are like terms (both have the variable "x"
- -1 and 2 are like terms (both without variables, also known as constants)
(f+g)(x) is equal to <u>4x+1</u> and the correct answer is A.
I gram = 0.00220462 pounds
so 14000 x 0.00220462 = 30.864717
round off answer as needed
You change the improper fraction into a mixed number. So 25/3 equals 8
Answer:
<em>It results -14 in either way</em>
Step-by-step explanation:
<u>Velocity As A Rate Of Change
</u>
The velocity of an object can be computed as the rate of change of its displacement (or position taken as a vector) over time. If we compute it as a derivative, it's called instantaneous velocity, and if computed as the slope of the function (difference quotient) at a certain point it's the average velocity
The position of the object as a function of time is
Computing the derivative
We can see it's a constant value. If we use the slope or rate of change:
Now let's fix two values for time
and compute the corresponding positions, by using the given function
Now we compute the average velocity
We get the very same result in both ways to compute v. It happens because the position is related with time as a linear function, it's called a constant velocity motion.
It takes 8 hours to drive to Joliet, and that's 6 hours more than half the time it takes to drive to Davenport. So, I did 8-6 which equals 2. So 2 hours is half the time it takes to get to Davenport, which means it takes 4 hours to get to Davenport.
