What is the explicit rule for this geometric sequence?

Mathematics
1 answer:
LiRa [457]2 years ago
8 0

Answer:

Tn = 2/3^(n-1)

Step-by-step explanation:

The nth term of a geometric progression is expressed as

Tn = ar^{n-1}

a is the first term

n is the number of terms

r is t common ratio

From the sequence

a = 2/9

r = (2/3)/(2/9) = 2/(2/3) =3

Substitute

Tn = 2/9(3)^(n-1)

Tn = 2/3^(n-1)

Hence the required equation is Tn = 2/3^(n-1)

Find f(x) =32<br> f(x)=3x-1
SIZIF [17.4K]

Answer:

Given f(x)=32

So we can substitute 32 in place of 'x'

So, f(x)=3x-1

=    f(x)=3(32)-1

=    f(x)=96-1

=    f(x)=95

f(x)=3x-1 = 95

Write an equation for the parabola who’s vertex is at (3,6) and which passes through (4,4)
Gekata [30.6K]

Problem

Solution

For this case we know that the vertex is given by (3,6) and the genera equation for a parabola is given by:

y= a(x-h)^2 +k

Where h = 3, k=6 and replacing we have:

y= a(x-3)^2 +6

And we can find the value of a with the point given x= 4, y=4

4= a(4-3)^2 +6

4= a +6

a= 4-6=-2

And the correct equation would be:

d. y= -2(x-3)^2 +6

Find the perimeter of given figure:
Afina-wow [57]

Answer:

≈ 18 cm

Step-by-step explanation:

1.  Find the length of half a circle of radius 3.5 cm:

\tt \cfrac{C}{2}= \cfrac{2\pi r}{2}=\pi r=3.14\cdot3.5=10.99 \ cm

2.  Find the length of the diameter:

D = 2r = 2 · 3.5 = 7 cm

3. Find the perimeter of the figure:

P = 10.99 + 7 = 17.99 ≈ 18 cm
