20,10,5, ...<br> Find the 9th term.
iren [92.7K]

Answer:

0.078125.

Step-by-step explanation:

This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.

nth term = a1 r^(n -1) so here:

9th term = 20(0.5)^(9-1)

= 20(0.5)^8

= 0.078125.

The graph below shows the velocity f(t) of a runner during a certain time interval:
Snezhnost [94]
When graphs are plotted, graphs as in the .jpeg image in attachment are obtained.
First graph is line going through ordered pair (point) (0,6) and pair (6,8).
The second graph is line going through ordered pair (6,8) and pair (8,0).
Intercept of these graphs is point (ordered pair) (6,8).
You see from the .jpeg image that the following is true:
Initial velocity of the runner is 6 meters per second (runner starts with this velocity), for a while he runs, velocity grows, then in the 6th second (time=6), runner starts to slow down and velocity starts to decrease, and runner stops totally at time = 8.
So runner stops after 8 seconds.
The 4th claim (sentence) is correct.

Mark's dad is three times older than Mark. Mark's sister is 2 years younger than Mark. (3m) The sum of their ages is 48. How old
nataly862011 [7]

Answer:

Age of Mark =10 years

Age of Mark's dad =30 years

Age of Mark's sister =8 years

Step-by-step explanation:

Let age of Mark be x years.

Mark's dad is three times older than Mark

Age of her Mark's dad =3x

Mark's sister is 2 years younger than Mark

Age of Mark's sister =(x-2) years

The sum of their ages is 48.

x+3x+x-2=48\\5x-2=48\\5x=50\\x=10

Age of Mark =x=10 years

Age of Mark's dad =3x=3(10)=30 years

Age of Mark's sister =x-2=10-2=8 years

What is the solution to the equation: 2 ∣ x + 1 ∣ + 3 = 11 ?
iren [92.7K]
Use inverse operations. 11 minus 3 is 8. 8 divided by 2 is 4. 4 minus 1 is 3.

(NOT SURE) x COULD equal 3, but the lines, as far as I know. relate to absolute value. So it could be |-3 + 1| and that would equal 4.

and if you put a variable next to a number, you multiply. so you multiply 2 by 3 plus 1, or 2 times 4, which equals 8. 8 plus 3 equals 11.

there :)
