Observation one

From the markings on the diagram <1 = 60o The left triangle is at least isosceles. Therefore equal sides produce equal angles opposite them.

Now we have accounted for 2 angles that are equal (each is 60 degrees) and add up to 120 degrees. The third angle (angle 2) is found from this equation.

<1 + 60 + <2 = 180 degrees.  All triangles have 180 degrees.

60 + 60 + <2 = 180

Observation 2

<2 = 60 degrees.

120 + <2 = 180

m<2 = 180 - 120

m<2 = 60 degrees.

Observation 3

m<3 = 120

<2 and <3 are supplementary.

Any 2 angles on the same straight line are supplementary

60 + <3 = 180

<3 = 180 - 60

<3 = 120

Observation 4

m<4 = 40 degrees.

All triangles have 180 degrees. No exceptions.

m<4 + 20 +m<3 = 180

m<4 + 20 + 120 = 180

m<4 + 140 = 180          

m<4 = 180 - 140

m<4 = 40

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

NeX [460]

Answer:

Step-by-step explanation:

19x-9 = 13x+15

by transposing

19x - 13x = 15 + 9

6x = 24

x = 24/6

x = 4
