Answer:
Hello there! I would say the answer is C,
Step-by-step explanation:
I hope this helps!!!
length of the slide is lets say 'l' the height (h) opposite to the angle 28 is found by h=l*sin28 where sin28=0.47 approximately h=4.5*0.47 h=2.115m
Given:
The graph of a line which represents position (m) at time (s).
To find:
The slope of the line.
Solution:
Formula for slope:
From the given graph it is clear that the line passes through two points (0,0) and (1,4).
Using the above formula, we get
Therefore, the slope of the line is 4 m/s.
4.6 because you round up because the next number is less than 5
Answer:
126.
Step-by-step explanation:
This is the number of combinations of 4 cards from 9 cards:
= 9C4
= 9! / 4! 5!.
A quick way of calculating this is
9*8*7*6
----------- = 9*2*7 = 126 combinations.
4*3*2*1
