Answer:
x=-3
remember its just the opposite when it comes to the x axis . hope this helped buddy :)
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!

Answer:
Volume left = 404.32 cubic inches
Step-by-step explanation:
volume of a cylinder = 
h
volume of ice cream in the cylindrical tub =
x
x 9
=
x 25 x 9
= 707.1429
Volume of ice cream in the cylindrical tub is 707.14 cubic inches.
The ice cream scoop has a spherical volume, so that;
volume of a sphere = 


r = 
=
inches
volume of the scoop =
x
x 
=
x
x 
= 8.1845
volume of the scoop is 8.19 cubic inches.
If he scoops 37 scoops,
volume of the 37 scoops = 37 x 8.1845
= 302.8265
volume of 37 scoops is 302.83 cubic inches.
Volume of ice cream left in the tub = 707.1429 - 302.8265
= 404.3164
Volume of ice cream left in the tub is 404.32 cubic inches.
If the diameter of the cylinder's base is 10, then the radius is half that, or 5.
