27. the y intercept is 2

28. the y intercept is -3

29. I cant answer because it is cut off in the picture...

Step-by-step explanation:

These equations follow a simple formula- the slope formula

Why is the answer A ?<br>why can't D work?
attashe74 [19]
The negative in a = -2 for answer A represents a reflection over the x-axis.
What does the cosine graph usually look like?.....It goes through point (0,1) and decreases.
The graph shown goes through point (0,-2). Since there are no vertical or horizontal shifts, the graph has an amplitude of 2 and reflects over the x-axis.

a=2 for answer D does not represent the reflection over the x-axis.

The length of a rectangular field is 4 m longer than its width.
Artyom0805 [142]
We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12

The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.

Park service personnel are trying to increase the size of the bison population of a large park. If 140 bison currently live in t
natali 33 [55]

Answer:

y(t) = 140 (2.7)^{0.01t}

Where t represent the time in years

For this case this model follows the general model given by:

y = a b^t

Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate

For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:

y(30) = 140(2.7)^{0.01*30} = 188.598

And if we round to the nearest whole number we got 189 bisons after 30 years

Step-by-step explanation:

For this case we have the following function given:

y(t) = 140 (2.7)^{0.01t}

Where t represent the time in years

For this case this model follows the general model given by:

y = a b^t

Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate

For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:

y(30) = 140(2.7)^{0.01*30} = 188.598

And if we round to the nearest whole number we got 189 bisons after 30 years
