Find the equation in standard form of the line passing through the points (2,-3) and (4,2)

Sonja [21]

The equation of the line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is

$\frac{x-x_1}{y-y_1} =\frac{x_2-x_1}{y_2-y_1}$ . Here $\frac{y_1-y_1}{x_2-x_1}$ is the slope of the line.

Substituting numerical values,

$\frac{x-2}{y+3} =\frac{4-2}{2+3} \\ \frac{x-2}{y+3} =\frac{2}{5} \\ 5x-10=2y+6\\ 5x-2y-16=0$

The equation of the line in standard form is $5x-2y-16=0$ .

In Exercise find the derivative of the functions.<br> f(x) = (4x - 3)(x2 + 9)

pashok25 [27]

Answer: $f'(x)=12x^2 - 6x+36$

Step-by-step explanation:

According to the product rule of derivatives.

$f'(x)=u'(x)v(x)+u(x)v'(x)$

The given function : $f(x) = (4x - 3)(x^2 + 9)$

here , $u(x) = 4x - 3$ and $v(x)=x^2 + 9$

Differentiate both sides with respect to x, we get

$u'(x) = 4+0=4$ and $v(x)=2x +0=2x$

$[\because \dfrac{d(ax)}{dx}=a\ , \dfrac{d(a)}{dx}=0 \ \&\ \ \dfrac{d(x^n)}{dx}=nx^{n-1}]$

Then, Tge derivative of withe respect to x will be :

$f'(x)=u'(x)v(x)+u(x)v'(x)$

$=4(x^2 + 9)+( 4x - 3)(2x)$

$=4x^2 +36+8x^2 - 6x$

$=12x^2 - 6x+36$

Hence, the derivative of the function is $f'(x)=12x^2 - 6x+36$ .

You invest $1300 in an account at 2% per year simple interest. The equation

myrzilka [38]

Answer:

B. $1430

Step-by-step explanation:

Put 6 in the equation for n and do the arithmetic.

A(6) = 1300 +(6 -1)(0.02·1300)

= 1300(1 +5(.02)) = 1300(1.1)

A(6) = 1430 . . . . matches choice B
