What is 0.91 meter equal to 1 what?
telo118 [61]

Answer:2.986

Step-by-step explanation:

0.91 meter = 2.986 feet

Formula: multiply the value in meters by the conversion factor '3.2808398950132'.

So, 0.91 meter = 0.91 × 3.2808398950132 = 2.986 feet.

0.91 METER TO THE NEAREST FRACTIONS OR INTEGER OF FOOT:

3 feet (e* = 0.48%)

The latest values above are alternative ones for 0.91 meter. They are represented in the form of usable fractions (1

2

, 1

4

, 3

4

etc.) or of an integer. We show these results, when it is possible to convert them to a fraction or integer with a small error e* which means the maximum rounding error (positive or negative).

To calculate a meter value to the corresponding value in feet, just multiply the quantity in meter by 3.2808398950131 (the conversion factor).

Here is the formula:

Value in feet = value in meter × 3.2808398950131

Suppose you want to convert 0.91 meter into feet. Using the conversion formula above, you will get:

Value in feet = 0.91 × 3.2808398950131 = 2.986 feet

Two terms of a geometric sequence are given. Find the first five terms. Please help asap
Zepler [3.9K]

Answer:

4, 8, 16, 32, 64

Step-by-step explanation:

The nth term of a geometric sequence is

a_{n} = a₁(r)^{n-1}

Given

a₇ = 256 and a₁₀ = 2048 , then

a₁ r^{6} = 256 → (1)

a₁ r^{9} = 2048 → (2)

Divide (2) by (1)

\frac{a_{1}r^{9}  }{a_{1}r^{6}  } = \frac{2048}{256}

r³ = 8 ( take the cube root of both sides )

r = \sqrt[3]{8} = 2

Substitute r = 2 into (1)

a₁ × 2^{6} = 256

a₁ × 64 = 256 ( divide both sides by 64 )

a₁ = 4

Then

a₁ = 4

a₂ = 2a₁ = 2 × 4 = 8

a₃ = 2a₂ = 2 × 8 = 16

a₄ = 2a₃ = 2 × 16 = 32

a₅ = 2a₄ = 2 × 32 = 64
