Tcecarenko [31]

Is there a list of statements? if not i would reason that if
Kayla’s puppy’s weight=k
and we know k=5 (pounds)
and Manuel’s puppy’s weight=m
then your equation would be something like 5*65=m
which means that m=325

Vlada [557]

$f(x) - g(x) = 9 {x}^{3} + 2 {x}^{2} - x + 4 - 5 {x}^{3} - 7x + 4 \\ = 4 {x}^{3} + 2 {x}^{2} - 8x + 8$

What is the sixth term of this sequence 1, 7, 49, 343, , 16,807?

bixtya [17]

Sequence: 1,7,49,343,??,16807, 7th term, 8th....

we notice that:

1st term = 1 or 7^0

2nd term = 7 or 7^1

3rd term =49 or 7^2

4th term = 343 or 7^3

5th term = ?? or 7^4 (=2401)

6th term = 16807 or 7^5

7th term = 117 647 or 7^6

nth term = (7)^(n-1)

Which function below would have the smallest Average rate of change From X =0 to x=2

babymother [125]

Answer:

See answer below

Step-by-step explanation:

Hi there,

To get started, recall the average rate of change formula (essentially the same thing as slope):

$Rate_{avg} = \frac{f(b)-f(a)}{b-a}$

So, just determine the average rate for each function between points [0,2] (a and b for the formula above, respectively).

To make it less time consuming, you do not need to do the division portion as it is same for all of them and (2-0) is greater than 1:

$f(2)-f(0)= \frac{1}{4} (2^{2} -0^{2} ) = 1 \\g(2)-g(0)= 5(2-0)= 10\\h(2)-h(0)= 2^{2} - 0^{2} =4$

Without even doing the divison of (b-a), we can already see that the function with smallest average rate of change between [0,2] is f(x).

thanks,
