The effect that 'h' have on the graph of a parabola is Horizontal shift or translation .
<h3>What is
translation?</h3>
A translation is the movement of a shape up, down , this can also be movement from side to side.
Even though there is movement, its appearance remains the same in any other way, hence, h values cause left or right movement with respect to the graph.

Answer:
answer = 12.87 km/h
Step-by-step explanation:
Given
Ship A is sailing east at 25 km/h = 
ship B is sailing north at 20 km/h =
here x and y are the sailing at t = 4 : 00 pm for ship A and B respectively
so we get x = 4 ×25 =100 km/h
y = 4× 20 = 80 km/h
let z is the distance between the ships, we need to find
at t = 4 hr
At noon, ship A is 130 km west of ship B (12:00 pm)
so equation will be


derivative first equation w . r. to t we get



![\frac{dz}{dt} =\frac{1}{z}[(x -130)\frac{dx}{dt} +y\frac{dy}{dt}]](https://tex.z-dn.net/?f=%5Cfrac%7Bdz%7D%7Bdt%7D%20%3D%5Cfrac%7B1%7D%7Bz%7D%5B%28x%20-130%29%5Cfrac%7Bdx%7D%7Bdt%7D%20%2By%5Cfrac%7Bdy%7D%7Bdt%7D%5D)


Answer:
Number of families will have both radio and television = 44
Step-by-step explanation:
Given:
Number of family have radio = 794
Number of family have TV = 187
Number of family haven't both = 63
Find:
Number of families will have both radio and television
Computation:
Number of families will have Tv or radio = 1,000 - 63
Number of families will have Tv or radio = 937
Number of family have one of them = 794 + 187
Number of family have one of them = 981
Number of families will have both radio and television = 981 - 937
Number of families will have both radio and television = 44
