Aboat at anchor is bobbing up and down in the sea. the vertical distance, y, in feet, between the sea floor and the boat is given as a function of time, t, in minutes, by y=15+sin(2πt).
(a) find the vertical velocity, v, of the boat at time t.
(b) make rough sketches of y and v against t.

Step-by-step explanation:

Given

(a)Vertical velocity v at time t

graph of y is similar to sin x but is it shifted by a unit of 15 units and repeat itself after 1 s

Graph of v(t) is similar to cos x but it is amplified by a factor of

answer: sensy

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
