Answer:
The Heaviside step function, or the unit step function, usually denoted by H or θ (but sometimes u, 1 or ), is a discontinuous function, named after Oliver Heaviside (1850–1925), whose value is zero for negative arguments and one for positive arguments.
Step-by-step explanation:
L at time ť will meet at the point z " given by the equations : z " = - ( c + U ) t ... + B ) t = ť + t " = 2y - t = tı ( 93 ) Therefore , we do not recover the value 2t = 2L / c ... if the extinction time is not zero in equation 92 , one can verify the equality t ' + t ... the mirror located on the arm covers the distance Ut ' during the time t
Sum means to add, so you are adding a and 46 to get k. k is given as 97 so your equation used to solve for a is a + 46 = 97, choice A from above.
We'll have this following figure drawn in the picture. Since we have an isosceles trapezoid, the diagonals are congruent. According to the conditions of the problem, these diagonals are perpendicular and then we can claim that we'll have right-isosceles triangles in this case. Indeed, ∠OBC = ∠FBD = 45°. Then, in the triangle BFD. BF=FD=23. It means the height is 23 cm. Obtaining this fact, we can easily calculate the area.

You'll answer this type of quest just like you'll answer any other multi step equation. You'll work it step by step.
