Determine the real roots of f (x) = −0.6x2 + 2.4x + 5.5:(a) Graphically.(b) Using the quadratic formula.(c) Using three iterations of the bisection method to determinethe highest root. Employ initial guesses of xl = 5 and xu = 10.Compute the estimated error εa and the true error εt after eachiteration.
The three methods used to find the real roots of the function are,
graphically, the quadratic formula, and by iteration.
The correct vales are;
(a) Graphically, the roots obtained are; x ≈ -1.629, and 5.629
(b) Using the quadratic formula, the real roots of the given function are; x ≈ -1.62589, x ≈ 5.62859
(c) Using three iterations, we have; the bracket is [tex]x_l[/tex] = 5.625, and [tex]x_u[/tex] = 6.25
Reasons:
The given function is presented as follows;
f(x) = -0.6·x² + 2.4·x + 5.5
(a) The graph of the function is plotted on MS Excel, with increments in the
x-values of 0.01, to obtain the approximation of the x-intercepts which are
the real roots as follows;
[tex]\begin{array}{|c|cc|}x&&f(x)\\-1.63&&-0.00614\\-1.62&&0.03736\\5.62&&0.03736 \\5.63&&-0.00614\end{array}\right][/tex]
Checking for the approximation of x-value of the intercept, we have;
[tex]x = -1.63 + \dfrac{0 - (-0.00614)}{0.0376 - (-0.00614)} \times (-1.62-(-1.63)) \approx -1.629[/tex]
Therefore, based on the similarity of the values at the intercepts, the x-
values (real roots of the function) at the x-intercepts (y = 0) are;
x ≈ -1.629, and 5.629
(b) The real roots of the quadratic equation are found using the quadratic
formula as follows;
The quadratic formula for finding the roots of the quadratic equation
presented in the form f(x) = a·x² + b·x + c, is given as follows;
[tex]x = \mathbf{ \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}}[/tex]
Comparison to the given function, f(x) = -0.6·x² + 2.4·x + 5.5, gives;
a = -0.6, b = 2.4, and c = 5.5
Therefore, we get;
[tex]x = \dfrac{-2.4\pm \sqrt{2.4^{2}-4\times (-0.6)\times 5.5}}{2\times (-0.6)} = \dfrac{-2.4\pm\sqrt{18.96} }{-1.2} = \dfrac{12 \pm\sqrt{474} }{6}[/tex]
Which gives
The real roots are; x ≈ -1.62859, and x ≈ 5.62859
(c) The initial guesses are;
[tex]x_l[/tex] = 5, and [tex]x_u[/tex] = 10
The first iteration is therefore;
[tex]x_r = \dfrac{5 + 10}{2} = 7.5[/tex]
[tex]Estimated \ error , \ \epsilon _a = \left|\dfrac{10- 5}{10 + 5} \right | \times 100\% = 33.33\%[/tex]
[tex]True \ error, \ \epsilon _t = \left|\dfrac{5.62859 - 7.5}{5.62859} \right | \times 100\% = 33.25\%[/tex]
f(5) × f(7.5) = 2.5 × (-10.25) = -25.625
The bracket is therefore; [tex]x_l[/tex] = 5, and [tex]x_u[/tex] = 7.5
Second iteration:
[tex]x_r = \dfrac{5 + 7.5}{2} = 6.25[/tex]
[tex]Estimated \ error , \ \epsilon _a = \left|\dfrac{7.5- 5}{7.5+ 5} \right | \times 100\% = 20\%[/tex]
[tex]True \ error, \ \epsilon _t = \mathbf{\left|\dfrac{5.62859 - 6.25}{5.62859} \right | \times 100\%} \approx 11.04\%[/tex]
f(5) × f(6.25) = 2.5 × (-2.9375) = -7.34375
The bracket is therefore; [tex]x_l[/tex] = 5, and [tex]x_u[/tex] = 6.25
Third iteration
[tex]x_r = \dfrac{5 + 6.25}{2} = 5.625[/tex]
[tex]Estimated \ error , \ \epsilon _a = \left|\dfrac{5.625- 5}{5.625+ 5} \right | \times 100\% = 5.88\%[/tex]
[tex]True \ error, \ \epsilon _t = \mathbf{\left|\dfrac{5.62859 - 5.625}{5.62859} \right | \times 100\%} \approx 6.378 \times 10^{-2}\%[/tex]
f(5) × f(5.625) = 2.5 × (0.015625) = 0.015625
Therefore, the bracket is [tex]x_l[/tex] = 5.625, and [tex]x_u[/tex] = 6.25

Answer:
Un motor de paso es un motor eléctrico CC sin escobillas que divide una rotación completa en varios pasos iguales. Rota una distancia incremental específica por cada paso. El número de pasos que se ejecutan controla el grado de rotación del eje del motor.
Los motores de paso tienen cierta capacidad inherente para controlar la posición, ya que tienen pasos de salida integrados. Pueden controlar con gran precisión cuán lejos y cuán rápido rotará el motor de paso. El número de pasos que ejecuta el motor es igual al número de comandos de pulsos del controlador. Un motor de paso rotará una distancia y a una velocidad proporcional al número de la frecuencia de sus comandos de pulso.

A cube of edge 4 inches is cut by a plane containing 2 diagonally opposite edges
of the cube find the area of the section formed.
Answer:
So its area A = 4 * 4sqrt(2) = 16sqrt(2) inches^2
Explanation:
In order to find the area of the section, we need to find the length of one of the diagonals.
Using the Pythagorean Theorem, a^2 + b^2 = c^2, we pick any side of the cube which in
itself is a square with sides 4 inches each. The length of the diagonal of the square is
2(4^2) = c^2 or c = 4sqrt(2).
To calculate the area of the section, we must first determine the length of one of the diagonals. Using the Pythagorean Theorem, [tex]\bold{a^2 + b^2 = c^2}[/tex], one selects any side of the cube which in its a square with four-inch sides.
The diagonal of a square has a length:[tex]\to 2(4^2) = c^2 \\\\ \to c = 4\sqrt{(2)}[/tex]
A section is now a rectangle with sides 4 and [tex]4\sqrt{(2)}[/tex]. So its area[tex]\to A = 4 \times 4\sqrt{(2)} = 16\sqrt{(2)}\ inches^2[/tex]
Therefore, the answer is "[tex]\bold{ 16\sqrt{(2)}\ inches^2}[/tex]".

charging method .Constant current method
Answer:
There are three common methods of charging a battery; constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit.
Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage. The current will then taper down to a minimum value once that voltage level is reached. The battery can be left connected to the charger until ready for use and will remain at that “float voltage”, trickle charging to compensate for normal battery self-discharge.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries. The battery must be disconnected, or a timer function used once charged.
Constant voltage / constant current (CVCC) is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level. The current then reduces as the battery becomes fully charged. The lead acid battery uses the constant current constant voltage (CC/CV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation.

engineering infrastructure decay, who is to be blamed?
President Donald Trump is expected to discuss infrastructure in his State of the Union address on Tuesday, but how exactly he plans to do so is unclear.
The Washington Post reports that White House press secretary Sarah Sanders told CNN on Tuesday that infrastructure could be an area of compromise for Democrats and Republicans, but according to The Wall Street Journal, Trump Administration officials pushed for the removal of a call for Congress to pass Trump’s infrastructure plan from an early draft of his State of the Union address.
Trump reportedly "hates" major parts of the infrastructure plan he unveiled in 2018, which proposed $200 billion in federal funding designed to finance new projects and repairs while incentivizing private investment.
No matter what Trump says about infrastructure during his State of the Union address, one thing is clear: America's infrastructure is in dire need of repairs.
According to the American Society of Civil Engineers' 2017 Infrastructure Report Card, which is published every four years, US infrastructure gets a D+ grade. It got the same grade in 2013.
The ASCE estimates the US needs to spend some $4.5 trillion by 2025 to improve the state of the country's roads, bridges, dams, airports, schools, and more.
The report breaks down the state of infrastructure in 16 different categories. Here's a look at each category's final grade, according to the organization.
