Each element is 2/3 times the previous one, so that's a geometric sequence.

6×(2/3)=4, 4×(2/3)=8/3, 8/3×(2/3)=16/9, 16/9×(2/3)=32/27

Answer: 6, 4, 8/3, 16/9, 32/27

The first three terms of arithmetic progression are -5,-1 and 3.Find the six term.​
vodomira [7]

Answer:

15

Step-by-step explanation:

The pertinent general formula for this arithmetic progression is

a(n) = a(1) + d(n - 1), where d is the common difference.  That difference is d = 4.

Here, a(n) = -5 + 4(n -1)

Therefore, a(6) = -5 + 4(5) = 15

Sorin hits a cricket ball straight up into the air. After 1.5s, the ball is falling straight down with a speed of 6.5 m/s. We wa
sveticcg [70]

Step-by-step explanation:

We have, Sorin hits a cricket ball straight up into the air. After 1.5 s, the ball is falling straight down with a speed of 6.5 m/s.

We want to find the initial vertical velocity of the ball.

The relation between initial speed, final speed, acceleration and time is given by using first equation of kinematics. Let v₀ is the initial speed. So,

v=v_o +at

Here, v = -6.5 m/s, t = 1.5 s and a = -g

v_o=v-at\\\\v_o=v+gt\\\\v_o=-6.5+9.8\times 1.5\\\\v_o=8.2\ m/s

So, the initial velocity of the ball is 8.2 m/s and the formula used is (1).

Two angles of a quadrilateral measure 200° and 50°. The other two angles are in a ratio of 4:7. What are the measures of those t
Andrews [41]

Answer:

all angles will be 200, 50 , 40 and 70 - hope this helped :)

Step-by-step explanation:

everything equals to 360 after added together

360 - 250 = 110

110 divided by 11 = 10

4:7 (x 10)

40:70

the other angels will be 40 and 70
