Two people are standing in a field. One person is flying a kite with a string that is 300 ft long. When the kite is directly above the second person, the cosine value of
the angle made by the string and the ground is :
How far apart are the two people?

Two parallel lines are crossed by a transversal.what is value of x

Find the volume of the described solid.the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x.a) 441b) 147c) 864d) 882

Write the summation to estimate the area under the curve y = 1 + x2 from x = -1 to x = 2 using 3 rectangles and right endpoints
