Answer:
x = 2 or x = 1 or x = 0 or x = -1 or x = -2
Step-by-step explanation:
Solve for x:
x^5 - 5 x^3 + 4 x = 0
The left hand side factors into a product with five terms:
x (x - 2) (x - 1) (x + 1) (x + 2) = 0
Split into five equations:
x - 2 = 0 or x - 1 = 0 or x = 0 or x + 1 = 0 or x + 2 = 0
Add 2 to both sides:
x = 2 or x - 1 = 0 or x = 0 or x + 1 = 0 or x + 2 = 0
Add 1 to both sides:
x = 2 or x = 1 or x = 0 or x + 1 = 0 or x + 2 = 0
Subtract 1 from both sides:
x = 2 or x = 1 or x = 0 or x = -1 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 2 or x = 1 or x = 0 or x = -1 or x = -2
Answer:
0+40+32=72. 0 is the smallest number for it unless your trying to use decimals. a=0 for the smallest

20 golf balls can fit in the can.
<u>Step-by-step explanation:</u>
Given:
Height (h) = 10 Inches
Volume of 15.625 Pi inches cube.
To Find:
How many balls can be filled in that can.
Solution:
Diameter of the golf ball [as per standard value] = 1.68 in
Radius of the golf ball = 
Volume of the golf ball = 
= 
= 
Volume of the can = 
Now we have to divide the volume of the can by the volume of the golf ball, we will get = 
balls
Thus we can conclude that approximately 20 balls can be filled in that can.
Answer:
10.1%
Step-by-step explanation:
The first thing we should do is calculate the total volume of the solution when mixing them would be:
0.7 + 0.3 = 1
Now, we have that the resulting concentration (x) would be equal to the sum of the multiplications between the volumes and the concentrations to be mixed, as follows:
x * 1 = 0.7 * 0.05 + 0.3 * 0.22
x = 0.035 + 0.066
x = 0.101
That is, the concentration of the resulting mixture would be 10.1% (0.101 * 100)
