Step-by-step explanation:
area of square = 1
area of a circle in square =
bu estimate
b) if n tend to infinity

Answer:
48
Step-by-step explanation:
u • w
= (i + 6j ) • (9i - 2j )
= (1 × 9 ) + (6 × - 2 )
= 9 + (- 12)
= 9 - 12
= - 3
v • w
= (5i - 3j ) • (9i - 2j )
= (5 × 9) + (- 3 × - 2)
= 45 + 6
= 51
Then
u • w + v • w
= - 3 + 51
= 48
A = 1/2 bh = 1/2 (3)(4) = 12/2 = 6
answer is B. 6 square units
Answer: y=-2/3x-2/3
Step-by-step explanation:
concept to know: two lines that are perpendicular has opposite reciprocal slopes.
y=-2/3x+b
in order to find b or the y-intercept, we need to plug in a point
3=-2/3(-4)+b
3=8/3+b
b=-2/3
y=-2/3x-2/3
Hope this helps!! :)
Answer:
Step-by-step explanation:
2/3x(-4)=20
2/3x*4=20
8/3x=20
8/3x/8/3= 20/8/3
0.83 but 3 is repeting
