A woman wishing to know the height of a mountain measures the angle of elevation of the mountaintop as θ1 = 11.6°. After walking d = 0.81 km closer to the mountain on level ground, she finds the angle to be θ2 = 13.7°. a. Draw a picture of the problem, neglecting the height of the woman's eyes above the ground. b. Select variable names for the mountain height (suggestion:y) and the woman's original distance from the mountain(suggestion: x) and label the picture. (Do this on paper. Your instructor may ask you to turn in this work.)c. Using the labeled picture and the tangent function, write two trigonometric equations relating the two selected variables. (Dothis on paper. Your instructor may ask you to turn in thiswork.)d. Find the height y of the mountain by first solving one equation for x and substituting the result into the other equation.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
