Number 4 the answer is C and number 5 is A
3 cups of baking soda, 1 1/2 cups of table salt, and 6 cups of vinegar
<span>The rule that applies to the following number:0÷7=0 is: "</span>Zero divided<span> by any number (except </span>0<span>) equals </span>zero"
Division by zero on the other hand is undefined, which means there is no solution to the operation : N:0.
Answer:
We have the function cos(x)*(cos(x) + 1) = 0
Here we have two sides of an equation:
if cos(x) = 0, then the equation is equal to zero (because this therm is multiplicating the whole equation), so the values pi/2, 3pi/2, etc, are solutions.
And if the parentheses is zero, (cos(x) + 1) = 0 then the equation is also zero
Then when cos(x) = - 1 is another solution
This means that x = pi, 3pi, etc.
