A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ______ units. The point (-7, ______) lies on this circle.How would I do this?
Answers
circle formula (x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r=radius
to find the radius we are given one of the points and the center distnace from them is the radius distance formula D= points (-3,2) and (1,5) D= D= D= D= D=5
center is -3,2 r=5 input (x-(-3))^2+(y-2)^2=5^2 (x+3)^2+(y-2)^2=25 is equation radius =5 input -7 for x and solve for y (-7+3)^2+(y-2)^2=25 (-4)^2+(y-2)^2=25 16+(y-2)^2=25 minus 16 (y-2)^2=9 sqqrt y-2=+/-3 add 2 y=2+/-3 y=5 or -1
the point (-7,5) and (7,-1) lie on this circle
radius=5 units the points (-7,5) and (-7,1) lie on this circle
A human red blood cell is 7.5 micrometers in diameter.1 centimeter = 10,000 micrometers What is the diameter in centimeters?
Answers
To solve this question, we do cross multiplication.
1 cm = 10,000 micrometers 7.5 micrometers.
? Cm = 7.5 micrometers X 1 centimetre/10000 micrometers.
? Cm = 0.00075 cm So 7.5 micrometers = 0.00075 centimetres.
