Answer:

an = 4 • -1^n

Step-by-step explanation:

Substitute in the value of  n  to find the  n th term.

a 2 = 4 ⋅ ( − 1 2 )  One to any power is one.  a 2 = 4 ⋅ ( − 1 ⋅ 1 )

Multiply  − 1  by  1 .

a 2 = 4 ⋅ − 1

Multiply  4  by  − 1 .

a 2 = − 4

-1 x 4= -4

-4 x 4= -16

-16 x 4= -64

-64 x 4= -256

-256 x 4= -1024

-1024 x 4= -4096

-4096 x 4= -16384

-16384 x 4= -65536

Please help me, I know it’s not the first one but I think it’s the last one. Can somebody please confirm or deny?

Answer:

B. 2.2π m² : 3.2π m²

Step-by-step explanation:

Given:

Slant height (l) = 2.2 m

Diameter (d) = 2 m

Radius (r) = ½(2) = 1 m

Required:

Lateral area and surface area

Solution:

✔️Formula for lateral area of a cone = πrl

Plug in the values

Lateral area of the cone = π*1*2.2

Lateral area = 2.2π m²

✔️ Formula for surface area of a cone = πr(l + r)

Plug in the values

Surface area of the cone = π*1(2.2 + 1)

Surface area = π(3.2)

Surface area = 3.2π m²

The answer would therefore be:

2.2π m² : 3.2π m²

Estimate plz:<br> 137,638+52,091<br> Explain plz how to do it
IceJOKER [234]
The best way to estimate it is to do "written addition" in your head, adding 1+8, then 9+3, all the way until you get to the front. the actual answer is 189,459, so your answer should be somewhere close to that.
