Reason Abstractly During a test flight, Jeri's rocket reached a height of 18 yards above the ground. This was 7 yards less than the height that Devon's rocket reached. Did Devon's rocket reach a height greater than 23 yards? Explain. Choose the best answer and explanation. A) no; If I solve the equation $x-7=18$ to find the height that Devon's rocket reached, I find that Devon's rocket reached a height of $18-7$ , or 11 yards. Because $11<23$ , Devon's rocket did not reach a height greater than 23 yards. B) no; If I solve the equation $x+7=18$ to find the height that Devon's rocket reached, I find that Devon's rocket reached a height of $18-7$ , or 11 yards. Because $11<23$ , Devon's rocket did reach a height greater than 23 yards. C) yes; If I solve the equation $x-7=18$ to find the height that Devon's rocket reached, I find that Devon's rocket reached a height of $18+7$ , or 25 yards. Since $25>23$ , Devon's rocket did reach a height greater than 23 yards. D) yes; If I solve the equation $x+7=18$ to find the height that Devon's rocket reached, Ifind that Devon's rocket reached a height of $18+7$ , or 25 yards. Because $25>23$ , Devon's rocket did reach a height greater than 23 yards.

Figure it thomure 6
In Figure 1, a person uses a pulley to lift a bell. The person pulls down on the rope at a constant speed. Power $P_{1}$ is delvered to the bell and it moves upward at a constant speed. In Figure 2, the person uses a double pulley. The person pulls down on the rope at the same constant speed. The bell again moves upward at a constant speed, but the speed of the bell is half the speed of the bell in Figure 1 . The power delivered to the bell in Figure 2 is $P_{2}$ . Which of the following correctly compares $P_{2}$ to $P_{1}$ and provides a valid justification? (A) $P_{2}<P_{1}$ , because in Figure 2 the force exerted on the bell is the same but it is moving with less speed than in Figure 1. (B) $P_{2}<P_{1}$ , because in Figure 2 the force exerted on the bell is less than in Figure 1. (C) $P_{2}=P_{1}$ , because in Figure 2 the speed is half that in Figure 1 , but the force on the bell is twice that in Figure 1. (D) $P_{2}=P_{1}$ , because in Figure 2 the person is doing the same amount of work on the bell as in Figure 1.
