First, 9.8 (Gravity) times 3 (time) equals 29.4, which is the velocity after 3 seconds. The kinematic equation for change in position that uses the variables we have is:
delta x= (v)(t) -0.5(acceleration)(time)^2
delta x= 29.4 times (3) - 0.5 (9.8) times 9
delta x= 44.1
100 minus 44.1 equals 55.9, which is the answer for part a.

PART B:
The kinematic equation for this is:
delta x= (initial velocity) times time plus 0.5 (a)(time)^2
100=(0)times(x) plus 0.5 (a)(time)^2
100=0.5(9.8)(x)^2
100=4.9x^2
100/4.9 is approxamitely 20.4.
The squareroot of this is approxamitely 4.5.

The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be
2/5 < 3/7 < 4/9
I hope the answer has helped you.
Answer:
90, 45
Step-by-step explanation:
0.3x = 27
x = 90
50% of 90 = 45
The value of angle x which is substended in the circle will be D. 342.6°.
<h3>How to calculate the circle?</h3>
From the information given, it has been depicted that the value of the angle that's facing x is 17.4°.
Therefore, the value of x which is inscribed in the circle will be:
= 360° - 17.4°
= 342.6°
In conclusion, the correct option is 342.6°.
