(2x - 1)(6x - 7)
2x(6x - 7) - 1(6x - 7)
2x(6x) - 2x(7) - 1(6x) + 1(7)
12x² - 14x - 6x + 7
12x² - 20x + 7

Find the slope given the points (-5,-3) and (2,4)
Setler79 [48]

Answer:

The slope of the line is 1.

Step-by-step explanation:

We are given two coordinate points:

  • (-5, -3)
  • (2, 4)

We can use the rate of change formula to find the slope of the points.

  • \displaystyle \frac{\triangle y}{\triangle x}

In mathematics, coordinate pairs are labeled as:

(x_1, y_1) \ \text{and} \ (x_2, y_2)

Therefore, we can relabel our points:

  • x_1 = -5
  • y_1 = -3
  • x_2 = 2
  • y_2 = 4

After we do this, we can expand the rate of change formula:

\displaystyle m = \frac{y_2-y_1}{x_2-x_1}

Now, we can use simple substitution to solve for m, or the slope.

\displaystyle m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-3)}{2-(-5)}\\\\m = \frac{7}{7}\\\\m = 1

Therefore, the slope of the line is 1.

How to determine the initial value from a table
ExtremeBDS [4]
The initial value of a function is the output value of the function when the input value is 0. For example, if your function is tracking how much money you made over a certain amount of time, then the initial value would be however much money you had to begin with on day 0.

Step-by-step explanation:

h = -4.9t^2 + 298t + 94

t = 0 seconds so it will be 3

h = -44.1 + 894 + 94

h = 943.9 m

Find the area of the surface. the part of the paraboloid z=4-x^2-y^2 that lies above the xy-plane
11Alexandr11 [23.1K]
Parameterize the surface (call it \mathcal S) by

\mathbf s(u,v)=\langle u\cos v,u\sin v,4-u^2\rangle

with 0\le u\le2 and 0\le v\le2\pi. Then the surface element is

\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|=u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv

The area of \mathcal S is then given by the surface integral

\displaystyle\iint_{\mathcal S}\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=0}^{u=2}u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv
=\displaystyle2\pi\int_{u=0}^{u=2}u\sqrt{1+4u^2}\,\mathrm du=\dfrac{(17^{3/2}-1)\pi}6\approx36.1769
