Answer:

Neither

Step-by-step explanation:

y - 4 = 7(x - 6)

y - 4 = 7x - 6

+4 +4

y = 7x - 2

______________

y = 5

x = 4

5 = 7(4) - 2

5 = 28 - 2

5 = 26

______________

y = 5

x = 6

5 = 7(6) - 2

5 = 42 - 2

5 = 40

Hope this helped! Have a nice day! Plz mark as brainliest!!! :D

Use the fact that the world population was 2560 million in 1950 and 3040 million in 1960 to model the population of the world in

zimovet [89]

Answer:

The populaton in year 1991 will be of 5178.9 million of people

and the population in year 2020 will be of 8524.60 million of people

Step-by-step explanation:

We measure the time t in years and let t=0 in the year 1950.

We measure the population P(t) in millions of people, then P(0)=2560 and P(10) = 3040.

Since we are assuming that dp/dt=kP, this theorem gives the following.

$P(t) = P(0)e^{kt}= 2560e^{kt}$

$P(10) = 2560 e^{10k} = 3040$

$k=\frac{1}{10} ln (3040/2560) = 0.0171$

The relative growth rate is about 1.7% per year and the model is

$P(t) = 2560e^{0.017185t}$

Year 1991 is equal in our formula to 41 and year 2020 is equal to 70. Replacing,

$P(41) = 2560e^{0.017185(41)}=5178.89$

$P(70) = 2560e^{0.017185(70)}=8524.60$

Therefore the populaton in year 1991 will be of 5178.9 million of people and the population in year 2020 will be of 8524.60 million of people

romeo ordered a bouquet of roses for his girlfriend. each rose cost $2.95. and the delivery charge was $8.50. if the total cost

LenaWriter [7]

Okay first you should subtract 8.50 from 61.60 because the delivery charge doesn't count. 61.60-8.50=53.1. now divide 53.1 by 2.95. 53.1÷2.95=18. Romeo ordered 18 roses for his girlfriend.
