8) BRAINLIEST + 15+ POINTS! :)<br><br> Which of the following is a graph of y=1/2 x +1
LuckyWell [14K]

Answer:

D

Step-by-step explanation:

We can rule out the second and third because the y intercept in those graphs are not 1

Now lets look at the point 2,5 on graph a

y=1/2x+1

so 5=1+1 but that is false

D is the answer by elimination

Use what you've learned in this unit to model the population of Western
nekit [7.7K]

The population function of the Western Lowland Gorillas can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

y = a(1 \pm r)^x

Where:

  • (a) represent the initial value i.e. the initial population of the Western Lowland Gorillas
  • (r) represents the rate at which the population increases or decreases.
  • (x) represents the number of years since 2022
  • (y) represents the population in x years

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

y = 2000 * 0.98^x

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

Carl earns $5.25 per hour walking his neighbors dogs. He walks them 2/6 of an hour in the morning and 1/2 of an hour in the afte
DIA [1.3K]
2/6 = 1/3 = 20 minutes
1/2 = 30 minutes
20 + 30 = 50 minutes

50 minutes x 7 = 350 minutes = 5 hours and 50 minutes
5 x $5.25 = $26.25
50 minutes = 5/6
5/6 of $5.25 = 4.375

Add $26.25 to the total for 50 minutes to get your answer. :)
