Elias purchases a home for $38,900. The value of the home, in thousands of dollars, since his purchase is shown in the table. Find an exponential function that models the data. Round numerical values to the nearest hundredth. Let x be the number of years since the purchase. The function f(x) =()x models the data. Use the model to predict the home’s value. After 12 years, the home’s value will be about $thousand. After 35 years, the home’s value will be about $thousand.

2. Another machine is used to make 10 mm long bolts. For this machine, the bolts must have an error of less than 0.1 mm to be accepted. This can be represented by |x – 10| < 0.1.a. Write this inequality as a compound inequality without absolute value bars.b. Solve the compound inequality.c. Graph the solutions on a number line.d. What do the solutions of the inequality mean for the bolt?3. Special precision bolts are made by another machine. These are for jobs that require more exact measurements. The bolts must be within 0.01 mm of 8 mm. This is represented by |x – 8| < 0.01. a. Write this inequality as a compound inequality without absolute value bars.b. Solve the inequality.c. Graph the solutions on a number line.d. What do the solutions of the inequality mean for the bolt?4. Suppose 1.5-inch long bolts are made by another machine and have to be within 0.125 inches of 1.5 inches.a. Write an absolute value inequality to represent this tolerance.b. Rewrite the absolute value inequality as a compound inequality without absolute value bars.c. Solve the compound inequality.d. What does the solution mean for the bolts?30 points!!! need help asape.

Line segment AB is shown on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment AB is shown with A as ordered pair 1, 3 and B as ordered pair 5, 3. The line segment is rotated 270 degrees counterclockwise about the origin to form A'B'. Which statement describes A'B'? A'B' is parallel to AB. A'B' is half the length of AB. A'B' and AB are equal in length. A'B' is greater than twice the length of AB.
