Given f ( x ) = 1 x + 10 , find the average rate of change of f ( x ) on the interval [ 8 , 8 + h ] . Your answer will be an exp

son4ous [18]

Answer: 1

Step-by-step explanation:

$f(8+h)=8+h+10=18+h\\\\f(8)=8+10=18$

So, the average rate of change is:

$\frac{(18+h)-18}{(8+h)-8}=\frac{h}{h}=\boxed{1}$

The question is wrong, the expression will not be in terms of h since it is a linear function.

find three consecutive negative integers such that six times the largest is equal to the twice sum of the two smaller integers.

Oksana_A [137]

Answer:

The consecutive negative integers are -3, -4 and -5.

Step-by-step explanation:

Let the three consecutive negative integers be k, (k-1) and (k -2)

Now, according to the question:

6(Largest Integer) = 2( Sum of smaller two Integers)

or, 6 (k) = 2( (k-1) + (k-2))

⇒ 6k = 2(2k -3)

or, 6k = 4k - 6

or, 6k - 4k = -6

or, 2k = -6 ⇒ k = -3

Hence, the largest negative integer = -3

The next two consecutive negative integer are (k-1) and (k-2) = (-3-1) and (-3-2)

= -4 and -5

Hence, the consecutive negative integers are -3, -4 and -5.

Given H = f(t) where H is the height in meters of an object and t is the time in seconds since it was launched, which of the fol

dangina [55]

Answer:

Recall that the height of the object, in meters, is a function of elapsed time, in seconds. Thus what $f(8)=12$ means is that the object is at a height of 8 meters when 12 seconds have passed since its launch.
