You can notice that each term of the sequence has a denominator with powers of 2. The first term has 2 powered to 0, the second term has a 2 powered to 1 and so on. The numerator is always 3.

Then, for the n-th term, you have:

a_n=\frac{3}{2^{n-1}}

makvit [3.9K]

Answer:

The answer is ≈ 6214.78

(could put the sign because it wouldnt let me)

Step-by-step explanation:

Formulas:

A= {2} \pi r h + 2\pi r^{2}

V=\pi r^{2}h

V= A \frac{r}{2} -\pi r^{2} =1890 *\frac{9}{2} -\pi *9^{3} = 6214.77896

rounded= 6214.78

Dimitri is helping to plan the school talent show. Each performer for the talent show has 6 66 minutes for his or her performanc
antoniya [11.8K]
The talent show consists of introduction and talent performance. It could be written into this equation
Talent show duration= introduction + talent performance

Each performer for the talent show has 6 minutes for their show, the <span>introduction of the talent show is 24 minutes, and the total duration should be 150 minutes. Then, maximum performance count of the show would be:
</span>
Talent show duration= introduction + talent performance
<span>150 min = 24 min + (performance count * 6min)
</span>performance count = (150min - 24min) / 6 min
performance count=21

I really don't understand this and my teacher won't explain it to me
Naya [18.7K]
I don't see "equation 1."  Where is it/

Just supposing that "equation 1" were y = 2x - 3.

Then points on the graph would be (-5,-13), (-2,-7), (0, -3), (2, 1) and (5, 7).  I got the x-values from the table for equation 1.

10 POINTS!! Made myself broke with my last two questions!
Svet_ta [14]

Answer:

D

Step-by-step explanation:

The radius r is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 5, - 12)

r = \sqrt{(-5-0)^2+(-12-0)^2}

  = \sqrt{(-5)^2+(-12)^2}

  = \sqrt{25+144}

  = \sqrt{169}

  = 13 → D
