I think you want me to solve for k
expanding, you get
24k-9=-42+24k
which is clearly no solution
Answer:
B. 
Step-by-step explanation:
Given:
A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters.
diameter of Sphere = 20 centimeters
hence radius = half of diameter = 
Hence we need to find the volume of sphere.
Volume of sphere = 
Here r is the radius of the circle.
Hence Volume of sphere = 
Hence Option B
is the correct answer.
First thing to do with this problem is to plot the given data in MS excel. We can see in the graph that the minima (lowest point of the graph) is at (4,-2) and the maxima is at (2,3). The critical points are points which the direction changes from one side to another.
Answer:50°
Step-by-step explanation:
2(x+10)=3x-30
2x+20=3x-30
50°=x
