Answer:
9.95+9.95+9.95= 29.85
50-29.85=20.15
I hope this was helpful <3
Answer:
Yes.
Step-by-step explanation:
If the slope between successive points have the same slope then they will form a straight line.
Slope = ( 3.5- -1) / (-2 - -8) = 4.5/6 = 3/4
Slope = (12.5 - 3.5) / (10 - -2) = 9 / 12 = 3/4
Slope = (20-12.5)/(20-10) - 7.5/10 = 3/4 .
So the answer is yes.
Well the first step would be to change each fraction into an improper fraction
8 3/4= 35/4, 2 1/2= 5/2 or 10/4, and 5 1/4= 21/4
Now multiply 35/4 by 10/4 and you get 350/16 but in simplest form it would be 175/8. Multiply that by 21/4 and you get 3,675/32 and change that into a mixed number. The answer would be 114 27/32
Answer:
Step-by-step explanation:
A) False ; R^2 is not a two dimensional subspace of R^3 because Vector R^2 will have 2 entries while vector R^3 has 3 entries
B) False : The number of variable in the equation is not equal to the Dimension because dim of Null A represents the number of free variables
C) False : This is because you can span R^3 with an infinite set of vectors but that doesn't make it infinite dimensional subspace
D) False : This is only possible when S has exactly n elements/vectors
E) True : Since R^3 is a three dimensional subspace it is spanned with 3 vectors whom are linearly independent
