Answer:

The required number of plants is 10.

Step-by-step explanation:

Nursery P charges $15 per plant plus a $50 delivery fee on any order. Nursery Q charges $20 per plant and no delivery fee.

If x number of plants that must be delivered for the total cost to be the same at both nurseries, then

15x + 50 = 20x

⇒ 5x = 50

⇒ x = 10

Therefore, the required number of plants is 10. (Answer)

A pile of coal is stored in a barrel-shaped bin whose base has a radius of 3 meters. the height of the pile measures 1.5 meters.
Aleksandr-060686 [28]

42.41 cubic meters    
The volume of a cylinder is bh where b is the area of the base and h is the height of the cylinder. And since the area of a circle is pi r^2, we have this equation for the volume of a cylinder  
V = pi*r^2*h    
Now substitute, the known values for r and h, then calculate the result:  
V = pi*r^2*h  
V = 3.14159*3^2*1.5  
V = 3.14159*9*1.5  
V = 42.411465  
V = 42.41   
 So the volume of the coal pile is 42.41 cubic meters.

Answer:

(a) Local Maximum (x,y) = (0,12)

    Local Minimum (x,y) = (-9,6) (smaller x-value)

    Local Minimum (x,y) = (6,3) (Larger x-value)

(b) Increasing = (-9,0)\cup (6,\infty)

    Decreasing = (\infty,-9)\cup (0,6)

Step-by-step explanation:

(a)

Local Maximum: The function gives maximum value in small neighborhood.

From the given graph it is clear that the maximum value of the function is 12 at x=0. So,

Local Maximum (x,y) = (0,12)

Local Minimum: The function gives minimum value in small neighborhood.

It is clear that the minimum value of the function is -6 and 3 at x=-9 and x=6. So,

Local Minimum (x,y) = (-9,6) (smaller x-value)

Local Minimum (x,y) = (6,3) (Larger x-value)

(b)

The function is increasing on -9<x<0 and after 6.

Increasing = (-9,0)\cup (6,\infty)

The function is decreasing on 0<x<6 and before -9.

Decreasing = (\infty,-9)\cup (0,6)

The change in the value of a stock is represented by the rational number -5.90 describe in words what this means
xxMikexx [17]

We are given : A stock is represented by -5.90.

The given number is a negative number.

Note: When a stock is given by a negative number, it represents the decrease in stock and when a stock is given by a positive number, it represents the increase in stock.

As we are given number is a negative number, we can just say that

" The stock value is being decrease by 5.90".
