answer:Here's an expanded version of the revised paragraph: Climate change is a pressing issue, and many people believe that human activity is the primary cause. There are numerous reasons contributing to this phenomenon, one of which is our collective failure to properly care for the planet. For decades, we have been releasing large amounts of greenhouse gases into the atmosphere, depleting natural resources, and destroying ecosystems, ultimately disrupting the delicate balance of the Earth's systems. However, it's not too late to take action and mitigate the effects of climate change. By acknowledging our role in this crisis, we can begin to make amends and work towards a more sustainable future. This can be achieved through individual actions, such as reducing energy consumption, using renewable energy sources, and adopting eco-friendly lifestyles. Moreover, governments and corporations must also take responsibility and implement policies that prioritize environmental protection and sustainable practices. By working together, we can reduce our carbon footprint, preserve the natural world, and create a better future for generations to come. I expanded the original paragraph by adding a second paragraph that transitions from discussing the problem to offering solutions. The phrase However, it's not too late to take action serves as a turning point, shifting the focus from the causes of climate change to the potential for positive change. I also emphasized the importance of collective action, highlighting the need for individual, governmental, and corporate responsibility in addressing the crisis. The second paragraph provides a sense of hope and empowerment, encouraging readers to take part in creating a more sustainable future.

answer:Here's a revised version of the second paragraph with a more impactful transition phrase: Climate change is a pressing issue, and many people believe that human activity is the primary cause. There are numerous reasons contributing to this phenomenon, one of which is our collective failure to properly care for the planet. For decades, we have been releasing large amounts of greenhouse gases into the atmosphere, depleting natural resources, and destroying ecosystems, ultimately disrupting the delicate balance of the Earth's systems. But the window for change is still open, and the choices we make today will determine the course of our planet's future. By acknowledging our role in this crisis, we can begin to make amends and work towards a more sustainable future. This can be achieved through individual actions, such as reducing energy consumption, using renewable energy sources, and adopting eco-friendly lifestyles. Moreover, governments and corporations must also take responsibility and implement policies that prioritize environmental protection and sustainable practices. By working together, we can reduce our carbon footprint, preserve the natural world, and create a better future for generations to come. Instead of using However, it's not too late to take action, I opted for a more urgent and motivational phrase: But the window for change is still open, and the choices we make today will determine the course of our planet's future. This revised transition phrase emphasizes the importance of immediate action and raises the stakes, making it clear that the decisions we make now will have a lasting impact on the planet. This phrase is more impactful because it creates a sense of urgency and encourages readers to take action before the opportunity for change slips away.

answer:Here's how you can implement this: ```python def solve_iteratively(a, b, c, tolerance): def get_x(a, b, c): return (c-b)/a threshold = tolerance x = get_x(a, b, c) while abs(a * x + b - c) > threshold: x = get_x(a, b, c) return x ```

answer:To find the number of positive integers less than or equal to 1000 that are divisible by 7 but not 11, we can start by counting the total number of integers divisible by 7. The largest multiple of 7 less than or equal to 1000 is 994, so there are 994 / 7 = 142 such multiples. However, some of these numbers are also divisible by 11, and we want to exclude those. To count how many numbers are divisible by both 7 and 11, we need to find the least common multiple (LCM) of 7 and 11. Since 7 and 11 are relatively prime, their LCM is simply 7 * 11 = 77. The largest multiple of 77 less than or equal to 1000 is 924, so there are 924 / 77 = 12 multiples of 77. Therefore, the number of positive integers less than or equal to 1000 that are divisible by 7 but not 11 is 142 - 12 = 130.
