Calculate the distance between (-2 - 5i) and (1 + 3i)

d = sqrt(73)

d is approximately 8.544003745

Step-by-step explanation:

To find the distance we use the formula

d = sqrt ( (x2 -x1)^2 + (y2-y1)^2)  

where x are the real coordinates and y is the imaginary coordinates

d = sqrt ( (1--2)^2 + (3--5)^2)  

d = sqrt ( (1+2)^2 + (3+5)^2)

d = sqrt ( (3)^2 + (8)^2)  

d = sqrt( 9+64)

d = sqrt(73)

d is approximately 8.544003745

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

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)
