Answer:
6. Bacteria tend to grow very fast in a petri dish at first because of unlimited food and then begin to die out due
to competition. In a certain culture, the number of bacteria is givenby N(f) =1f +92t+.625' where /
represents the hours since 625 bac,teriawere introduced to the Petri dish. Determine the *={TlgX9"t
of bacteria that occur in the dish.
Step-by-step explanation:
t= -92/-2(2) =23
N (23) power 2 +92(23) + 625 =1628

Answer:
A
Step-by-step explanation:
The colour keeps switching from red to blue to red, and red was last in the series. Therefore, a blue pattern should be next in the series.
Each time, a new hand is added to the pattern. Therefore, we add a hand.

Answer:
<h3>19</h3>
Step-by-step explanation:
Given the triangle WXY, with angle X and W to be equal, this shows that the triangle is an isosceles triangle. An isosceles triangle is the one which has two of its sides and its base angle to be the same.
If <X = <W, then The sides YW = XY
That is the other two sides asides from the side XW are equal.
Since YW = 19
Hence the measure of the side XY will also be 19
YW = XY = 19
Answer:
12 years.
Step-by-step explanation:
Le x represent number of years.
We have been given that type A is 8 feet tall and grows at a rate of 18 inches per year. So growth of type A in x years would be 
inches.
1 feet = 12 inches.
8 feet = 8*12 inches = 96 inches.
9 feet = 9*12 inches = 108 inches.
The total height of type A would be 
inches.
We are also told that type B is 9 feet tall and grows at a rate of 17 inches per year. So growth of type B in x years would be 
inches and total height of type B would be 
inches.
To find the years when both trees will be of the same height, we will equate height of both trees and solve for x as:
Therefore, after 12 years the height of these trees will be the same.
