Answer:
we're is the graph I need the graph then I could help you out
Answer:
a⁴ + 20a³ + 150a² + 500a + 625
Step-by-step explanation:
(a + 5)⁴
₄C₀ a⁴ 5⁰ + ₄C₁ a³ 5¹ + ₄C₂ a² 5² + ₄C₃ a¹ 5³ + ₄C₄ a⁰ 5⁴
a⁴ + 4 a³ 5 + 6 a² 25 + 4 a 125 + 625
a⁴ + 20a³ + 150a² + 500a + 625
Answer:
Biosphere 2 is a unique facility that allows scientists to research ecosystems and environmental effects in a controlled environment. The controlled environment of the biosphere allows researches to obviate uncontrolled variables that might have an unintended effect on their research. This allows for specific hypothesis about the environment to be tested with a higher degree of certainty. They can study how the ecosystem is affected when there are artifically induced limiting factors. The ability of the scientists to control factors in the ecosystem lets them model almost any environment on earth.

Step-by-step explanation:
Properties of a circumcenter;
1). Circumcenter of a triangle is a point which is equidistant from all vertices.
2). Point where perpendicular bisectors of the sides of a triangle meet is called circumcenter of the triangle.
From the picture attached,
9). AG = GB = GC = 21
10). BC = 2(DC)
= 2×16
= 32
11). By applying Pythagoras Theorem in ΔGFB,
GB² = GF² + FB²
(21)² = GF² + (19)²
441 = GF² + 361
GF² = 441 - 361
GF =
GF = 8.9
12). By applying Pythagoras theorem in ΔGDB,
GB² = DG² + BD²
(21)² = (DG)² + (16)² [BD = DC = 16]
DG² = 441 - 256
DG = √185
DG = 13.6
