Step-by-step explanation:
1. The product of the third power of a and the fourth power of b =
.
The 'third power of a' means 'a to the power 3' and 'fourth power of b' means 'b to the power 4'.
2. Six less than three times the square of Y means
.
Here, 'three times the square of Y' means 'product of 3 and Y to the power 2', and 'six less than' means 'subtract 6 from the expression'.
3. The sum of a and b increase by the quotient of b and a means
.
Here, 'quotient of b and a' means 'b divided by a'.
4. Four times the sum of r and a increased by twice the different r and s means
.
Here, 'increased by' means 'addition' and 'different r and s' means 'r minus s'.
5. Triple the difference of 55 and cube of w means
.
Here, triple means 3 times. (Answer)
Cross multiplication
420/18 357/x
420*x = 357*18
420x=6426
/420 /420
x=15.3 gallons
By definition we have that the average rate of change of the function is given by:
![AVR = \frac{f(x2) - f(x1)}{x2 - x1} ](https://tex.z-dn.net/?f=AVR%20%3D%20%20%5Cfrac%7Bf%28x2%29%20-%20f%28x1%29%7D%7Bx2%20-%20x1%7D%0A%20)
Substituting values we have:
![AVR = \frac{100 - 50}{2 - 0}](https://tex.z-dn.net/?f=AVR%20%3D%20%5Cfrac%7B100%20-%2050%7D%7B2%20-%200%7D%20)
Rewriting we have:
Answer:
If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.
