Answer:
The best prediction for the number of years it will take for the population to reach 200,000 is 9.41
Step-by-step explanation:
Year Population
1 11,920
2 16,800
3 23,300
4 33,000
5 45,750
6 64,000
Substitute the values
Divide 1 and 2
The exponential function that passes through the points (1, 11920) and (2, 16800) is
Now we are supposed to find the best prediction for the number of years it will take for the population to reach 200,000
t = 9.41
Hence the best prediction for the number of years it will take for the population to reach 200,000 is 9.41
Answer:
(5, -2)
Step-by-step explanation:
You have to reverse it.
Up 2 units and right 6 units gets you to your original position.
275+180+120=575 or <span>275+180+120=120+180+250 (commutitative property of addition)</span>
Answer:
10.92
Step-by-step explanation:
1. Find all side lengths of this tetrahedron.
A to B is 2 units
A to C is 2 units
A to D is 2 units
B to C is square root of 8
B to D is square root of 8
C to D is square root of 8
See 3D distance formula attached below to get the answers above.
2. Find the area of the triangles
Triangle ACD can be calculated using Heron’s formula, which is also attached below.
Area of Triangle ACD is 2 units squared.
Area of Triangle ABD is congruent to the previous one so it is also 2 units squared.
Area of Triangle CBD is roughly 3.46 units squared.
Area of Triangle ABC is congruent to Triangle CBD so it is also 3.46 units squared.
Adding them altogether is 2 + 2 + 3.46 + 3.46 = 10.92
