Answer:

1000 * 3^{9} Bacteria after 18 hours,

Step-by-step explanation:

The condition given in the problem is that the number of bacterial triple after every 2 hours.

So, after 2 hours, total bacteria= 1000 * 3

So, after 4 hours, total bacteria= 1000 * 3 * 3

Therefore, the general format for the number of bacteria is 1000 * 3^{n}, where n is the number of times the bacteria has tripled.

In 18 hours, there are \frac{18}{2} ties that the bacteria has tripled.

Therefore, the no. of bacteria after 9 hours= 1000 * 3^{9}

Help SOS pretty please ​

Answer:

x = 12

Step-by-step explanation:

Recall: the secant-tangent rule states that when a secant and a tangent meet at an external point of a circle, the product of the secant and the external segment is equal to the square of the tangent segment

(x)(3) = 6² (secant-tangent rule)

3x = 36

Divide both sides by 3

3x/3 = 36/3

x = 12

which of the following the range of function includes -4? A. y=sqrt(x)-5 B. y=sqrt(x)+5 C. y=sqrt(x+5) D. y=sqrt(x-5)
Ede4ka [16]
All of the equations contain -4 in their range.
A) -4 = sqrt(x) - 5
1 = sqrt(x)
x = 1; valid
B) -4 = sqrt(x) + 5
-9 = sqrt(x)
x = 81; valid
C) -4 = sqrt(x + 5)
16 = x + 5
x = 11; valid
D) -4 = sqrt(x - 5)
16 = x - 5
x = 21
I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.
