Tonya runs 8 kilometers in 60 minutes.At this rate,how long it take her to run 2 kilometers

1 answer:

8 0

15 Minutes

You have 8 km in an hour.

Divide all that by two and you'll have 4 km in 30 mins.

Then divide by two again to end up with 2 km in 15 mins.

You could alternatively divide by four from the beginning, but I find this easier.

How do I convert standard form to point slope

Fittoniya [83]

The point-slope form:

$y-y_1=m(x-x_1)$

$(x_1,\ y_1)$ - given point

$m$ - given slope

The standard form:

$Ax+By=C$

$y-y_1=m(x-x_1)$ use distributive property

$y-y_1=mx-mx_1$ add $y_1$ to both sides

$y=mx-mx_1+y_1$ subtract $mx$ from both sides

$-mx+y=-mx_1+y_1$ change the signs

$mx-y=mx_1-y_1$

A bacteria culture contains 1500 bacteria initially and doubles every hour. (a) Find a function N that models the number of bact

Tpy6a [65]

Answer: a) $N(t)=1500(2)^t$

b) 25165824000

Step-by-step explanation:

The exponential equation for growth is given by :-

$y= ab^t$ , where a= initial value , b =multiplicative growth factor and t = time.

Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.

i.e. a = 1500 and b= 2

Then, the function N that models the number of bacteria after t hours will be :

$N(t)=1500(2)^t$

To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get

$N(24)=1500(2)^{24}\\\\=1500(16777216)=25165824000$

Hence, the number of bacteria after 24 hours is 25165824000.
