Answer:

Step-by-step explanation:

first we turn ur mixed number into an improper fraction

1 1/4 = 5/4

the reciprocal of 5/4 can be found by just flipping it....so the reciprocal is gonna be 4/5

so 1 1/4 subtracted from its reciprocal is :

4/5 - 5/4 =

16/20 - 25/20 =

- 9/20 <====

I believe it’s -9/20. It’s based on reciprocals.

h(x)=x 2 −1h, left parenthesis, x, right parenthesis, equals, x, squared, minus, 1 Over which interval does h hh have a negative
Semenov [28]

Answer:

(C)−3 ≤ x ≤ 1

Step-by-step explanation:

The average rate of change of function h over the interval a \leq x\leq b, is given by this expression:

\dfrac{h(b)-h(a)}{b-a}

Given the function h(x)=x^2-1 on the interval:− 3 ≤ x ≤ 1

h(1)=1^2-1=0\\h(-3)=(-3)^2-1=9-1=8

The average rate of change:

\dfrac{h(b)-h(a)}{b-a}=\dfrac{0-8}{1-(-3)}=\dfrac{-8}{4}=-2

Therefore, the function has a negative average rate of change over the interval − 3 ≤ x ≤ 1.

CHECK:

(A)Average rate of change of h(x) over the interval − 3 ≤ x ≤ 5=2

(B)Average rate of change of h(x) over the interval 1 ≤ x ≤ 4=5

(D)Average rate of change of h(x) over the interval − 1 ≤ x ≤ 5=4

Light travels at the speed of approximately 3.0 × 108 meters per second. Find the time in minutes required for light to travel f
expeople1 [14]
Speed = distance / time => time = distance / speed
speed = 3x10^8 x 60 = 180x10^8 m per minute
time = 1.5x10^11/180x10^8 = 150x10^9/180x10^8 = 5/6x10 = 8,3 minutes

Given g(x)=3x+6 on what interval is the function negative
iris [78.8K]

Step-by-step explanation:

A number that is negative is less than 0, so

3x + 6 < 0

3x <  - 6

x <  - 2

So this function is negative, when x is less than -2
