A scientist is studying the population growth rates of two different types of bacteria under the same laboratory conditions. The number of bacterial cells of type A is represented by the equation shown, where Prepresents the number of badenas at the end of x hours
P = 2€ + 19
The number of bacterial cells of type B is represented by the equation shown, where o represents the number of bacterial cells at the end of Xhours
O
3+ 18
Which statement is true?
O At the end of 18 hours, there will be the same number of bacterial cells of type A and type B
At the end of 3 hours, there will be the same number of bacterial cells of type A and type B
At the end of 1 hour, there will be the same number of bacterial cells of type A and type B

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.

i don't think there is enough
