The picture shows a triangular island:

A right triangle is shown with an acute angle equal to 45 degrees. The length of the side of the triangle opposite to the acute angle is a. The length of the side of the triangle adjacent to the acute angle is b. The length of the hypotenuse is c.

Which expression shows the value of c?

b over tan 45 degrees
b over cos 45 degrees
a cos 45°
a tan 45°

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
