What is the 8th term in a geometric sequence where the first term is equal to 4 and the common ration is 2?
DochEvi [55]

Answer:

512

Step-by-step explanation:

1st term =a

common ratio = r

a*r with the exponent n-1

a=4    r=2 n=8

8th term    4*(2 at the seventh power)= 512

OR

1st term  :4

2nd term = 4*2=8

3rd term 8*2=16

4th term  12*2=32...............8th term 256*2=512

Line segments JK and JL in the xy-coordinate plane both have a common endpoint J (-4,11) and midpoints an M1 (2,16) and M2 (-3,5
Arisa [49]

Answer:

12.1  

Step-by-step explanation:

The dashed line joining M₁ and M₂ is the hypotenuse of a right triangle as shown in red below.

The base of the triangle is

x₂ - x₁ = 2 - (-3) = 2+ 3 = 5

The height of the triangle is

y₂ - y₁ = 16 - 5 = 11

We can now use Pythagoras' theorem to calculate distance between the two midpoints.

x² = 5² + 11² = 25 + 121 = 146

x = √146 = 12.1

The distance between M₁ and M₂ is 12.1.

What is the slope?<br> Write it as an integer ,improper fraction or proper fraction
skelet666 [1.2K]

Answer:

-3/2

Step-by-step explanation:

pick any 2 points on the graph. I chose (80,10) and (60, 40) because they are easy to identify.

<u>40- 10 = 30</u>

60-80 = -20

slope = -30/20 or -3.2
