Answer:
20. 300π m³
21. 457 1/3 π cm³
Step-by-step explanation:
20. r = 10 ÷ 2 = 5
V = 5² × 12 × π = 25 × 12π=300π m³
21. r = 14 ÷ 2 = 7
V = 457 1/3 π cm³
Answer:
Step-by-step explanation:
The given equation is in the form
We have to evaluate the correct system of equations which can be used to find the roots of the equation.
We can find the root of the equation by plotting the graph of the equations. In order to graph, we can assume the left and right hand side of the given equation as two separate equations.
Therefore, we have
Now, we plot the graph of these two equations in the same coordinate plane. The intersection point (s) would be the roots of the given equation.
Hence, the system of equation that we can use to find the root of the given equation is
Last option is correct.
Answer:
The product is positive, thus it is
Step-by-step explanation:
The full question in proper notation is:
"Find the product. If the result is negative, enter "-". If the result is positive, enter "+".
"
We have to work with it using Order of operations know as well as PEMDAS, thus expression inside parenthesis go first and exponents.
On this expression we have to work with exponents
Thus we get
Lastly we can work with multiplication and remembering that the multiplication of two negative signs becomes positive.
So the final simplified expression is
