a. Draw nABC with obtuse /C and construct its orthocenter O. Th en fi nd the orthocenters of nABO, nACO, and nBCO. What did you discover? Explain why you get this result. b. Will your conjecture be true for any acute or right nABC? Explain your reasoning.

it is a reproduction.

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

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:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
