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]

Area = SQRT(2)[4/3 - 4/5]

Area = SQRT(2)[8/15) = 0.754

Igoryamba

Answer:

Martin is 40 and Ada is 14

Step-by-step explanation:

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

Martin is two years younger than three times his daughter Ada’s age:

m = 3a - 2

The sum of their ages is 54:

m + a = 54

Solving this equation for m:

m = 54 - a

Eliminate m:

3a - 2 = 54 - a

Solve for a:

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

Find m:

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
