Look at some shorter periods of time to decide whether their reasonable. Do that by simplifying the fraction. . . . . 40,000 pounds / 80 years = 4,000 pounds / 8 years = 2,000 pounds (1 ton) / 4 years = 1,000 pounds / 2 years (have you decided yet ? Well, simplify it some more) 1,000 pounds / 2 years = 500 pounds per year = almost 1 and 1/2 pounds of bread every day of your life. NOW what do you think ? Make sense ?

What value must be defined for to remove the discontinuity of this function at ?
olchik [2.2K]

Answer:

Option D. 8

Step-by-step explanation:

we have

f(x)=\frac{x^{2}-16 }{x-4}

Remember that

x^{2}-16 =(x+4)(x-4)

substitute

f(x)=\frac{(x+4)(x-4)}{x-4}

Remove the discontinuity at x=4

Simplify

f(x)=(x+4)

so

Find the value of f(4)

For x=4

f(4)=(4+4)=8

I need help on all these 3 questions plz
DIA [1.3K]

Answer:

  1. Circumference
  2. Area
  3. Circumference

Step-by-step explanation:

Circumference would be if the situation is asking for the amount of something around the edge. For example, the number of tiles to be placed around the swimming pool would be asking for circumference.

Area would be if the situation is asking for the amount of something spread through the entire item. For example, the amount of water total in a swimming pool would be asking for area.

Hope it helps!
