What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?

fenix001 [56]

Step-by-step explanation:

$\to 1,728 \times {10}^{9}$

$= 1,728 \times {10}^{9}$

$= 1,728 \times 1.000.000.000$

$= 1.728.000.000$

$1,728 \times {10}^{9} = 1.728.000.000$

$\:$

$\to 4,8 \times {10}^{6}$

$= 4,8 \times {10}^{6}$

$= 4,8 \times 1.000.000$

$= 4.800.000$

$4,8 \times {10}^{6} = 4.800.000$

A line includes the points (4,1) and (8, 2). What is its equation in slope-intercept form?

Alisiya [41]

Answer:

$y = \frac{1}{4} x$

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula $m= \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of the given points into the formula and solve:

$m = \frac{(2)-(1)}{(8)-(4)} \\m = \frac{2-1}{8-4}\\m = \frac{1}{4}$

Thus, the slope is $\frac{1}{4}$ .

2) Now, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation in point-slope form (from there we can convert it to slope-intercept). Substitute values for $m$ , $x_1$ , and $y_1$ .

Since $m$ represents the slope, substitute $\frac{1}{4}$ for it. Since $x_1$ and $y_1$ represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, the end result will be the same) and substitute its x and y values into the formula as well. (I chose (4,1), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the answer.

$y-(1) = \frac{1}{4} (x-4)\\y-1 = \frac{1}{4} x-1\\y = \frac{1}{4} x+0\\y=\frac{1}{4}x$
