Find the 10th term of the geometric sequence 10, -50, 250, ... I need the help

Answer:  -19531250

Step-by-step explanation:

The formula for the nth terms of a geometric or exponential sequence is

 nth term = arⁿ ⁻ ¹ , where n = 10th terms, and a = 10

To find the common ratio, we divide the second term by the first term

r  = -50/10

  = -5

Now substitute for those values in the formula

T₁₀ = 10(-5)¹⁰ ⁻ 1

     =  10(-5)⁹

     =  10 x -(5)⁹

     =  10 x  -1953125

     = -19,531,250

Therefore the 10th terms of the geometric sequence

    = -19531250

If 25^x+1 = 125/5^x find the value of x
storchak [24]
  • Answer:

<em>x =1/3</em>

  • Step-by-step explanation:

<em>25ˣ⁺¹ = 125/5ˣ</em>

<em>5²⁽ˣ⁺¹⁾ = 5³/5ˣ</em>

<em>5²⁽ˣ⁺¹⁾ = 5³ : 5ˣ</em>

<em>5²⁽ˣ⁺¹⁾ = 5³⁻ˣ</em>

<em>2(x + 1) = 3 - x</em>

<em>2x + 2 = 3 - x</em>

<em>2x + x = 3 - 2</em>

<em>3x = 1</em>

<em>x = 1/3</em>

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
<span> 
it consists of a rectangle, dimensions  L = 4ft and W = 3ft = Ar = 4ft x 3ft = 12 ft^2

</span>then, you have one half of the area of the circle that has diameter  R = 3ft - radius will be r = 1.5ft the area of that half will be:

Ac = r^2 \pi/ 2
= (1.5 ft)^2 x 3.14 / 2
= 2.25 ft^2 x 3.4/2 
= 7.065 ft^2/ 2 
= 3.5325ft^2

A = Ar + Ac
A = 12ft^2 + 3.5325ft^2
A = 15.5325ft^2

<span>At the rate of $2 per square foot, the cost will be: 
$ 15.5325*2 = 31.07 </span>

svlad2 [7]

Answer:

P(t) = 10t - 400

Step-by-step explanation:

Selling price of each ticket = $10

Cost of setting up the dance= $400

Profit = Revenue - cost

Revenue = price × quantity

Revenue that will maximize profit = 10t

where t= quantity of tickets that maximises profits

Cost = $400

Profit(t) = Revenue - cost

P(t)= 10t - 400
