What is the recursive formula for this geometric sequence with this explicit formula?
BabaBlast [244]

D

the n th term (explicit ) formula for a geometric sequence is

a_{n} = a_{1}(r)^{n-1}

The given explicit formula therefore has

a_{1} = 5 and r = - \frac{1}{8}

The recursive formula, allows us to find the next term in the sequence from the previous term

Here the next term in the sequence is obtained by multiplying the previous term by - \frac{1}{8}

a_{n} = a_{n-1}(- \frac{1}{8}) with a_{1} = 5

If this trapezoid is moved through the
miskamm [114]

Hi! I'm happy to help!

We can see that A's coordinates currently are -6 for x and 2 for y.

When we move x+3, it moves the x coordinate to the right 3 units. This changes it from -6 to -3. When we move y -2, we move the y coordinate down 2 units. This changes it from 2, to 0.

To sum it up: The final coordinates of A will be -3 for x and 0 for y, also written as (-3,0).

I hope this was helpful, keep learning! :D

A rectangular prism with length 12 m , width 8 m & height 15 m , find its surface area .
Irina-Kira [14]

Answer: 792\ m^2

Step-by-step explanation:

Given

The length of the rectangular prism is l=12\ m

width of the rectangular prism is w=8\ m

height of the rectangular prism is h=15\ m

The surface area of the rectangular prism is 2[wl+lh+hw]

Put the values

\Rightarrow 2[8\times 12+15\times 12+15\times 8]\\\Rightarrow 2[96+180+120]=2\times 396\\\Rightarrow 792\ m^2

The surface area of the rectangular prism is 792\ m^2

The figures are similar. Find the area.
Crazy boy [7]

Answer:

108 in

Step-by-step explanation:

The figures are similar, so if we find a relation of the area and the diagonal in rectangle 1  we can apply it to rectangle 2.

rectangle 1 :

72/x=12

x=6

therefore

72/6=12

rectangle 2:

A/x=18

A/6=18

6*18=108

A=108 in

Hope this helps

Find the lateral area of a cylinder with the given measurements. Use 3.14 for pi and round your answer to the nearest tenth.

height: 15 centimeters

radius: 9 centimeters

Question 11 options:

787.3 cm2

1356.5 cm2

847.8 cm2

889.9 cm2

So we know the formula for the lateral area of a cylinder is:

AL=2πrh

now all we have to do is put the given value in place of the correct variable then solve like so:

AL=2*3.14*9*15

AL= 847.8 cm2

so the answer is the third option

hope this helps
