Is 3.
3×3=9
Hope this helps!
Average speed = (1/2) (beginning speed + ending speed)
= (1/2) ( 13 m/s + 30 m/s )
= (1/2) ( 43 m/s )
= 21.5 m/s
The final answer will be a 3x3 matrix. So you'll have 3 rows and 3 columns.
Along row one, the values are: 10, 15, 20
Along row two, the values are: 45, -5, -35
Along row three, the values are: 55, 25, -15
all of which make up the final answer. Each value in bold is the result of multiplying the outer 5 by each value inside the original matrix given. In a sense, it's like using the distributive property, though we wont be adding any of the values (everything stays separated).
Answer:
see below
Step-by-step explanation:
In decimal, the values of the fractions are ...
-0.2 = -0.200
-3/7 = -0.429
-2/8 = -0.250
So, in a, b, c order, they are ...
a = -3/7
b = -2/8
c = -0.2
