Dale is spreading grass seed over the putting green on a golf course. The circular green is centered about the cup with a radius of 30 feet. If each bag of grass seed covers 315 ft^2, how many bag(s) of grass seed does Dale need? QUESTION FROM MATH NATION!!!

9 bags

Step-by-step explanation:

We need to find the area of the putting green with a radius of 30 ft

A = pi r^2

A = 3.14 (30)^2

A =2826 ft^2

Each bag will cover 315 ft^2

Divide the area by 315 ft^2 to determine the number of bags

2826/315 =8.971428571 bags

Rounding up to the nearest bag

9 bags

9 bags

Step-by-step explanation:

Total area = 3.14 × 30²

= 2,826

No. of bags:

2,826/315

= 8.9714285714

To cover the area, he needs 9 bags

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
