Answer:

The cost of 3 magnets is $1

The cost of 9 magnets is $3

The cost of 6 magnets is $2

Step-by-step explanation:

The cost of magnets is calculated using the equivalent ratio. If 3 magnets cost $ then the multiple used for the calculations of more magnets is 3. The ratio for every magnet price is 1 : 3 which means every dollar will be equal to 3 magnets. The cost of 3 magnets is $1, the cost of 6 magnets is $2 and cost of 9 magnets is $3.

Over what interval is the graph of f(x) = -(X + 8)2 - 1 decreasing?

Naddika [18.5K]

Answer:

Function is decreasing on (-8,infinity)

Step-by-step explanation:

The given function is $f(x)=-(x+8)^2-1$

The first derivative is given by

$f'(x)=-2(x+8)$

For the function to be decreasing, we have

$f'(x)$

Divide both sides by -2. Since, we are dividing by a negative number hence, the inequality sign will change.

$(x+8)>0$

Subtract 8 to both sides

$x>-8$

Therefore, the function is decreasing on (-8,infinity)

First option is correct.
