The 3rd term of a geometric sequence is -1/3 and the 8th term is 81. what is the 11th term?
shepuryov [24]

Answer: t_{11}=-2187

Step-by-step explanation:

t_{3}=-1/3

That is :

ar^{2} = -1/3 ................. equation 1

Also

t_{8}=81

that is

ar^{7}=81 ................. equation 2

divide equation 2 by equation 1 , that is

\frac{ar^{7}}{ar^{2}} = 81 / -1/3

r^{5}= 81 x -3/1

r^{5}= -243

find the fifth root of both sides

r = -3

substitute r = -3 , into equation 1 to find a , that is

a(-3^{2})= -1/3

9a = -1/3

multiply through by 3

27a = -1

a =- 1/27

To find the 11th term , the formula for the 11th term is given as :

t_{11}=ar^{10}

t_{11}= -1/27(-3^{10})

t_{11}=-2187

Find the area of the region enclosed by x(t)=t^2-2t, y(t)=sqrt(t), and the y-axis. ...?
zaharov [31]
First find the the value of t where the curve intersects the Y-axis. This is when x = 0. 

x = t^2 - 2t = 0 = t(t - 2) 


So t= 0 and t = 2 

dA = (0 - x)*dy .... Since the curve has negative x in this region 

y = SQRT(t) and dy = [(1/2)/SQRT(t)]dt 

dA = [2t - t^2][(1/2)/SQRT(t)]dt 

dA = [t^(1/2) - (1/2)t^(3/2)]dt 


Integrate to get: A = (2/3)t^(3/2) - (1/5)t^(5/2) 


Now evaluate from t= 0 to t = 2. 


Area = [(2/3)2^(3/2) - (1/5)2^(5/2)] - [0] 
<span>
Area = SQRT(2)[4/3 - 4/5] 
</span><span>
Area = SQRT(2)[8/15) = 0.754

Martin is two years younger than three times his daughter Ada’s age. The sum of their ages is 54. If Ada’s age is given by a, th
Igoryamba

Answer:

  • Martin is 40 and Ada is 14

Step-by-step explanation:

  • Martin's age = m
  • Ada's age = a

<u>Martin is two years younger than three times his daughter Ada’s age:</u>

  • m = 3a - 2

<u>The sum of their ages is 54:</u>

  • m + a = 54

<u>Solving this equation for m:</u>

  • m = 54 - a

<u>Eliminate m:</u>

  • 3a - 2 = 54 - a

<u>Solve for a:</u>

  • 3a + a = 54 + 2
  • 4a = 56
  • a = 56/4
  • a = 14

<u>Find m:</u>

  • m = 54 - 14 = 40

Martin is 40 and Ada is 14

What is the value of a in the polynomial
Alexandra [31]

Answer: a= 16

Step-by-step explanation:

We have the following expression:

(y-4)(y^2 +4y +16)

To find the value of the coefficient "a" you must use the distributive property to multiply the expression:

(y-4)(y^2 +4y +16)

until you transform it to the form:

y^3 +4y^2 +ay -4y^2 -ay-64

Then we have

(y-4)(y^2 +4y +16)\\\\(y^3 +4y^2 +16y -4y^2 -16y-64)\\\\

Therefore the value of a in the polynomial is 16
