Step-by-step explanation:
Given that : 
Let 
then our equation become;
.....[1]
A quadratic equation is of the form:
.....[2] where a, b and c are coefficient and the solution is given by;

Comparing equation [1] and [2] we get;
a = 2 b = -1 and c =-1
then;

Simplify:

Basic Power Rule:
- f(x) = cxⁿ
- f’(x) = c·nxⁿ⁻¹
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² + x³
<u>Step 2: Find Derivative</u>
- Basic Power Rule: f'(x) = 2 · 3x²⁻¹ + 3 · x³⁻¹
- Simplify: f'(x) = 6x + 3x²
<u>Step 3: Analyze</u>
We see that our derivative is the graph of some sort of parabola. The parabola would be opening upwards.
Therefore, the maximum value of the derivative would be ∞, as the parabola's output <em>y</em> infinitely increases.
For sp3d hybridized central atoms, the only possible molecular geometry is trigonal bipyramidal.
Hybridisation (or hybridization) is a process of mathematically combining two or more atomic orbitals from the same atom to form an entirely new orbital different from its components and hence being called as a hybrid orbital.
In this case, if all the bonds are in place, the shape is also trigonal bipyramidal.
In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid.
Bond angle(s): 90°, 120°
Coordination number: 5

Answer:
the answer is D.
Step-by-step explanation:
(2s-5+4s-13)*2=108
(6s-18)*2=108
12s-36=108
12s=108+18
s=12
2*12-5=24-5=19 mi
4*12-13=48-13=35 mi
The percent of increase is 20%.
In order to solve this problem you have to solve this equation:
18-15/15
