Answer:

Step-by-step explanation:

If the graph has a filled-in dot on the starting number, that means the inequality is either ≥ or ≤; because these signs mean "greater/less than or equal to"

If the graph does not have a filled-in dot on the starting number, that means the inequality is either > or <; because these signs mean "greater/less than"

If 0 is greater than X, then X could be any number lower than 0; or all negative numbers.

If 0 is less than X, then X could be any number higher than 0; or all positive numbers.

The table below represents an exponential function. what is the missing value?

Blababa [14]

Answer:

The missing value is 128

Step-by-step explanation:

we know that

The equation of the exponential function is of the form

$f(x)=a(b^{x})$

where

a is the initial value (value of the function when the value of x is equal to zero)

b is the base

r is the rate

b=(1+r)

In this problem , looking at the table, we have that the number of bacteria is doubled every second

$r=100\%=100/100=1\\b=1+r=1+1=2\\a=8$

substitute in the formula

$f(x)=8(2^{x})$

where

f(x) is the number of bacteria

x is the time in seconds

For x=4 sec

substitute

$f(4)=8(2^{4})$

$f(4)=128\ bacteria$

Jeanette wants to raise $3,200 in a marathon fundraiser. Her sponsers will donate

rosijanka [135]

Total amount she wants to raise = $3200

Amount she'll get for each kilometer = $35

So, number of kilometers she need to run

= Total amount she wants to raise/Amount she'll get for each kilometer

= $3200/$35

= 91.42....

Since her sponser is will donate only for whole kilometers she'll have to run 92 km.
