1.Find the answer:

A Little League baseball "diamond" is actually a square, 60 feet on a side (see the gure). What is the distance directly from rst base to third base (the diagonal of the square)? The distance directly from rst base to third base is approximately D feet. (Type an integer or decimal rounded to two decimal places as needed.) Find an equation of the line containing the centers of the two circles whose equations are given below. x2+y2-2x+8y+1=0 x2+y2+8x+2y+16=0 The equation of the line is D. (Simplify your answer. Use integers or fractions for any numbers in the equation.) Earth is represented on a map of a portion of the solar system so that its surface is the circle with equation x2 + y2 + 2x + 4y - 4895 = 0. Aweather satellite circles 0.7 unit above Earth with the center of its circular orbit at the center of Earth. Find the general form of the equation for the orbit of the satellite on this map. The general form of the equation for the orbit of the satellite on this map is D. (Simplify your answer. Type an equation) Solve the system of equations. If the system has no solution, say that it is inconsistent. = 10 X 6 2 = 44 X Hint: Let u = = and v=
