Let B be the basis of P3 consisting of the Hermite polynomials in Exercise 21, and let p.t / D 7 ! 12t ! 8t 2 C 12t 3. Find the

Anastasy [175]

To calculate the relative vector of B we have to:

$P_B=\left[\begin{array}{ccc}3\\3\\-2\\3/2\end{array}\right]$

The coordenates of:

$p(t)= 12t^3-8t^2-12t+7$ , with respect to B satisfy:

$C_1(1)+C_2(2t)+C_3(-2+4t^2)+C_4(-12t+8t^3)= 7-12t-8t^2+12t^3$

Equating coefficients of like powers of t produces the system of equation:

$\left \{ {C_1-2C_3=7} \atop {2C_2-12C_4=-12} \right. \\\left \{ {{4C_3=-8} \atop {8C_4=12}} \right.$

After solving this system, we have to:

$C_1=3\\C_2= 3\\C_3= -2\\C_4= \frac{3}{2}$

And the result is:

$P_B=\left[\begin{array}{ccc}3\\3\\-2\\3/2\end{array}\right]$

Can some please help me do this? Thanks

Slope intercept form is y=MX+b.
M is the slope, x is the x intercept, and b is the y intercept

the slope is
$\frac{ - 2}{1}$
An intercept is where the formula crosses the axis. therefore, the x intercept is .5, and the y intercept is 1
so the point slope formula is
$y = \frac{ - 2}{1} 0.5 + 1$

Completely simplify the rational expression LaTeX: \frac{7x}{3y} + \frac{12x}{9y}

irina [24]

Answer:

$\frac{11x}{3y}$

Step-by-step explanation:

$\frac{7x}{3y} + \frac{12x}{9y}$

To add the two fractions, you need a common denominator. In this case, the lowest common denominator (LCD) is 9y. That's because 9y is divisible by both 3y and 9y.

The first fraction must be changed so that its denominator is 9y. Do this by multiplying both numerator and denominator by 3.

$\frac{7x}{3y}\cdot\frac{3}{3}+\frac{21x}{9y}=\frac{21x}{9y}+\frac{12x}{9y}\\=\frac{21x+12x}{9y}\\=\frac{33x}{9y}$

Finally, this answer can be simplified ("reduced") by dividing both numerator and denominator by 3, their greatest common factor.
