Answer:
C. His estimate is incorrect; it should be closer to 12 than 11.
Step-by-step explanation:
1. 11^2 is 121, √(140^2) is 140, and 12^2 is 144.
2. Based off these numbers 140 is closer to 144, meaning that √(140) is closer to 12 than 11.
Therefore, the correct answer is C. His estimate is incorrect; it should be closer to 12 than 11.
The height of the rocket is modeled by the equation: h(t)=-16t^2+32t+10, which is a quadratic equation. Here h(t) represents the height of the rocket after t seconds. Answers are: A- The number of seconds after the rocket released. This is correct ( it is t ). B- The initial height of the rocket(also false, this is h(0)=10) C - The initial velocity of the rocket( false, there is no vi ) D - the height of the rocket after t seconds ( false, this is h(t) ).
I put the line/graph on the attached file, when you draw the line make sure it goes through some of the points that I plotted.
Answer:
B
Step-by-step explanation:
When there is only rotation and reflection, there is no change in size. A change in size occurs when there is dilation.
