3948 bricks are used to build a wall as shown in diagram 1.1 . the size of each wall is given in ratio as below:
wall 1: wall 2 : wall 3
x x +5 x
solve for x if i unit of ratio is equivalent to 282 bricks.

a = 11 : 4

b = 38

c = 1 for every 6

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

y=20x

hope this

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
