Answer:
C
Explanation:
Please refer to the picture attached.
To find the solution for the polynomial, since the highest power of the equation is 2, u can use the formula as stated in the picture to solve the equation to find the 2 solutions.
In the options above, only C matched one of the 2 answers of this equation.
Answer:
When non metals such as nitrogen and phosphorus are solids, they tend to be very dull and brittle which is due to the tendency of elements to revert to their original form.
The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.
<h3>How to calculate the volume of a cylinder?</h3>
Mathematically, the volume of a cylindrical tank can be calculated by using this formula:
V = πr²h
Where:
Differentiating with respect to h, we have:
dV/dt = πr²(dh/dt)
3 = 3.142 × 5² × dh/dt
3 = 78.55dh/dt
dh/dt = 78.55/3
dh/dt = 26.18 m/mn.
