Answer:
The beach ball can hold 523.33 cubic inches of air
Step-by-step explanation:
Diameter of beach ball = 10 inches
Radius of beach ball =
We are supposed to find How many cubic inches of air can the beach ball hold
Volume of sphere =
Where r is the radius
So, volume of sphere =
Hence The beach ball can hold 523.33 cubic inches of air
The system has infinitely many solutions or has no solutions when:
.
1. k=3, then
has no solutions, because
.
2. k=-3, then
has infinetely many solutions, because
.
When
, the system has unique solution.
Answer:
pOH = 9.4
Step-by-step explanation:
Mathematically;
pH + pOH = 14
pOH = 14 - pH
But pH = -log[H3O+]
From the question [H3O+] = 2.5 * 10^-5
Thus pH = -log (2.5 * 10^-5)
pH = 4.6
Thus;
pOH = 14-4.6
pOH = 9.4
A line is undefined and can be described as a "stream" of points that has no width or depth. Because you can measure the distance between points, lines have one dimension: length. The answer is a line.
