Which of the following could be true if y ≤ -75?
ch4aika [34]

Hello!

Lets go through each choice, and determine if it is correct.

So, the symbol ≤, means less than or equal to. So our answer must be less than -75 or -75 on the dot.

A: y = 75

Okay, so we can tell this one is wrong off the bat. 75 is much more than -75. (Make sure you notice the symbol!) So it cannot be equal to said answer. A is wrong.

B: y =-74

Another trick question! When you are in the negatives, less is more! So -74 is actually greater than -75. This is also incorrect!

C: y > -75

This one is straight forward. Our equation up top strictly says <em>less than or equal too</em>, while C says greater than. Incorrect!

D: y = -75

The last answer! We see that the symbol in our equation up top says less than or equal too, and y = -75 is equal. This is the correct answer.

Our correct answer is D: y = -75

A cell of some bacteria divides into two cells every 10 minutes.The initial population is 3 bacteria. (a) Find the size of the p
mars1129 [50]

Answer:

(a) P_{t}=3(2)^{6t}

(b) 3(2)^{42}

(c) 28.07 minutes

Step-by-step explanation:

A cell of some bacteria divides itself into 2 cells in every 10 minutes and initial population of the bacteria was 3.

That means sequence formed will be 3, 6, 12, 24............

We can easily say that this sequence is a geometric sequence having common ratio (r) = \frac{T_{2}}{T_{1}}=\frac{6}{3}

r = 2

Now we know the explicit formula of a geometric sequence is given by

P_{t}=P_{0}(r)^{\frac{60t}{10}}=P_{0}(r)^{6t}

Where a = Initial population = 3 bacteria

r = common ratio = 2

and t = time in hours

So explicit formula will be P_{t}=3(2)^{6t}

(a) Now we have to calculate the size of population after t hours

P_{t}=3(2)^{6t}

(b) We have to find the size of population after 7 hours or 420 minutes

P_{t}=3(2)^{6\times7}

= 3(2)^{42}

After 7 hours bacteria population will be 3(2)^{42}

(c) Time to reach population as 21

By the explicit formula

21=3(2)^{6t}

2^{6t}=\frac{21}{3}=7

Now we take log on both the sides of the equation

log(2^{6t})=log(7)

6t log2 = log 7

6t(0.301) = 0.845

t(1.806) = 0.845

t = \frac{0.845}{1.806}=0.468 hours

Or t = 0.468×60 = 28.07 minutes

Therefore, after 28.07 minutes bacterial population will be 21
