Trapezoid ABCD and efgh are similar. The area of ABCD is 2.25 times that of efgh given the information below calculate the perimeter of efgh. To the upside down trapezoid e to F is 18 the normal standing trapezoid b-to-c on top is 24 cm the right side C to D is 21 cm the bottom a to d is 57 cm A to B is unknown

m a t h w a y. c o m

step-by-step explanation:

answer: the answer is e

step-by-step explanation:

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:

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.
