Answer:
A) x^2 + 2x+ y^2 - 4y + z^2 - 2z - 63 = 0
B) radius = 5
center = (4,-1,-3)
Step-by-step explanation:
A ) Determine the curve in which the sphere intersects the yz-plane
determine the radius ( r ) = √((6-(-1))2+(-2-2)2+(3-1)2) = √69
next the equation of the sphere ( curve in which the sphere intersects the yz-plane )
x^2+2x+y^2-4y+z^2-2z-63 = 0
B) determine the center and radius of the sphere
X^2 + y^2 + z^2 -8x + 2y +6z + 1 = 0
(x-4)2+(y+1)2+(z+3)2 = 25 = 52
radius = 5
center = (4,-1,-3)
Answer: I do not know but i asked my parents it is the 3 one

Answer:
799/5
Step-by-step explanation:
143+34(3)/5+(13)(3)4/+(11)(3/)5
=143+9/45+(13)(3)/4+(11)(3)/5
=143+9/20+(13)(3)/4+(11)(3)/5
=2869/20+(13)(3)/4+(11)(3)/5
=2869/20+394+(11)(3)/5
=766/5+(11)(3)5
=766/5+33/5
=799/5
Answer:
200 in^2
Step-by-step explanation:
First step- the first square shows the lenght and the bottom shows the width and 10 times 10 is 100
step 2- so the first is 100 double it and 100 times 2 is 200
Step 3- so 200 inches^2 is your anwser.
Try doing A, 2/3 Hopefully it helps you, I'm not good with fractions.
