Answer:

First drawing - answer is:  D: DG, FG and DE

Second drawing - answer is:  π (pi)

Third drawing - answer is:  70° ( If you mean on measure of central angle which is corresponing to the arc CB)

Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )

Step-by-step explanation:

For the second drawing

arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π

For the third drawing

∠CAB is peripheral angle of the central angle ∠CFB.

∠CFB= 2·∠CAB= 2· 35° = 70°

Good luck!!!

Study the geometric sequence {-4, -84, -1764, -37044, ...}.
Nonamiya [84]

Answer:

              \bold{a_n=(-4)21^{n-1}}

Step-by-step explanation:

a_1=-4\,,\ a_2=-84\,,\ a_3=-1764\,,\ a_4=-37044\quad\implies\ \ r=21

{-84:(-4)=21 and -1764:(-84)=21 and -37044:(-1764)=21}

geometric sequence formula:   a_n=a_1r^{n-1}

a_1=-4\quad and \ \ r=21

a_n=(-4)21^{n-1}

How can undefinable terms be used to create precise mathematical definitions?
chubhunter [2.5K]

Answer:

This is done by stating descriptions of these terms.

Step-by-step explanation:

Undefinable terms are terms with no formal definitions. Formal definitions are obtained when specific words are used to define a term. In mathematics, specifically, Geometry words like line, point, and plane have no definite definition, So descriptions are used to identify them.

For example, in describing a point, we note that a point has no dimensions, it is usually denoted with a capital letter, and it indicates a position. Also in a coordinate plane, it is denoted with descriptions such as  (u,v). Corresponding descriptions are given of other undefinable terms.
