Step-by-step explanation:
there are 31 days in January 5 of those are prefect squares (1,4,9,16,25)
Answer:
1. The missing value is 9
2. The missing value is 81
Step-by-step explanation:
1. To find the missing value of a perfect square you divide the center term (-6 as is -6x) by two to get 3 then square the three to get 9
To check this write it as the simplified form (x-3)^2 and multiply it out again using foil. x times x is x^2, -3 times x is -3x ( this happens twice adding up to the -6x), and -3 times -3 is 9 making it x^2 -6x +9
2. Follow the steps for the previous problem to get the same answer for this one. Divide 18 (middle term) by 2 making 9. Then square the 9 making 81.
Answer:
The velocity of the ball relative the racquet is 15 m/s.
Step-by-step explanation:
Given;
velocity of the tennis ball, 
= 30 m/s
Velocity of the racquet swung in opposite direction, 
= 15 m/s
The velocity of the ball relative the racquet (
) is calculated as;
Therefore, the velocity of the ball relative the racquet is 15 m/s.
