Answer:

1) y intercept (0,-2)  x intercept (2,0)

2) y intercept (0,2) x intercept (2,0)

3) y intercept (0, -5)  x intercept (-1,0)

Step-by-step explanation:

An ordered pair is in the form (x,y)  The x tells me how far away from zero a point it.  If it is a positive number, then it is to the right of zero.  If it is a negative number, then it is to the left of zero.

The y tells us how far up or down the point is from zero.  A positive number is above zero and a negative number is below zero.

The point right on the x axis is our x intercept.  The point right on the y axis is our y intercept.  

I did the first three, I  think that you can do the rest.

qwelly [4]

Answer:

Step-by-step explanation:

Given that,

Cells are divided into two cell every 20mins, this implies that the half-life is 20mins

Initial population growth is 60cells

Growth rate r?

Population growth is modeled as

P(t) = Po•exp(rt)

Where,

Po is the initial growth at t= 0

Po= 60

P(t) is population at any time t.

Since the population doubles every 20mins(⅓hr)

Then, P(⅓) = 2×60 =120

Then, P(t) = 120cells

So, applying the formula

P(t) = Po•exp(rt)

120 = 60•exp(⅓r)

120/60 = exp(r/3)

2 = exp(r/3)

Take In of both sides

In(2) = r/3

Cross multiply

r = 3In(2)

r = 2.079 /hour

The growth rate is 2.079/hour.

JulsSmile [24]

Answer:

1 minute

Step-by-step explanation:

We can see that Lisa types 165 words in 3 mins.

So she types 55 words in 1 minute.

How did I work that out?

Well, all you really do is \frac {165}{3} which is equal to \frac{55}{1} if you divide top and bottom by 3. Anything divided by 1 is itself.
