Gavin and Brianna want to know how far a mountain peak is from their houses. They measure the angles between the line of sight to the peak and to each other’s houses and carefully make the drawing shown. The actual distance between Gavin and Brianna’s houses is 1.5 miles. a. What is the actual distance of the mountain peak from Gavin’s house? Round your answer to the nearest tenth of a mile.
b. What is the actual distance of the mountain peak from Brianna’s house? Round your answer to the nearest tenth of a mile.

Will give brainliest b. describe the function over each part of its domain. state whether it is constant, increasing, or decreasing, and state the slope over each part.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
