The long way to obtain the ratio would be to calculate the circumference of each circle and them compare them to find the ratio. However, that is not necessary. The formula for circumference …

Explanation: #cos t = sqrt2/2# Trig table and unit circle give 2 solutions --> #t = +- pi/4# Note that #t = (7pi)/4# is co-terminal to #t = (-pi/4)#. Therefor the 2 answers are: #t = pi/4 + 2kpi#, and #t …

The circles do not overlap. Smallest distance between them is 4 If you find the distance between centres then directly compare it to the sum of the radii you can determine if they do overlap or …

Circle A has a center at # (7 ,-5 )# and a radius of #1 #. Circle B has a center at # (4 ,2 )# and a radius of #4 #. Do the circles overlap? If not, what is the smallest distance between them?

If the ratio of its length to its width is 3:2, find the length of the rectangle? How do you combine like terms in # (6n ^ { 3} - 7+ 6n ^ { 2} ) + ( 4- 7n ^ { 2} - 6n ^ { 4}) + (8n^4 - 8n )#? What is a …

Circle A has a center at # (1 ,8 )# and an area of #15 pi#. Circle B has a center at # (5 ,3 )# and an area of #25 pi#. Do the circles overlap? GeometryAnalytic GeometryDistance between Points

Circle A has a radius of #1 # and a center at # (3 ,3 )#. Circle B has a radius of #3 # and a center at # (1 ,7 )#. If circle B is translated by #<2 ,4 >#, does it overlap circle A? If not, what is the …

May 9, 2017 · The domain is (-oo, oo) and the range is (0, oo). Given: y = 2^(-x) First note that this is well defined for any real value of x. So the domain is the whole of RR, or in interval …

How do you find the roots, real and imaginary, of h = − − t2 + 16t − 4 using the quadratic formula? Algebra Quadratic Equations and Functions Quadratic Formula

Before calculating d we require to find the new centre of B under the given translation which does not change the shape of the circle only its position.
