Crank

The volume of given cube is: $4.29 * 10^{-5}$ cubic meters

Step-by-step explanation:

Volume of a cube is given by:

$V = a^3$

Given

Edge of the cube = $3.5*10^{-2}$

Putting the value of edge

$V = (3.5*10^{-2})^3\\V = 42.875 * (10^{-2})^3\\V = 42.9 * 10 ^{-2*3}\\V = 42.9 * 10^{-6}\\V = 4.29 * 10 * 10 ^{-6}\\V = 4.29 * 10^{-5}\ cubic\ meters$

The volume of given cube is: $4.29 * 10^{-5}$ cubic meters

3. Try It #3 Write the point-slope form of an equation of a line with a slope of -2 that passes through the point (-2,2). Then r

vova2212 [387]

Answer:

Point-slope form of equation given as $y-2=-2(x+2)$ .

Slope-intercept form of equation is given as $y=-2 x-2$ .

Step-by-step explanation:

In the question, it is given that the slope of a line is -2 and it passes from (-2,2).

It is asked to write the point-slope form of the equation and rewrite it as slope-intercept form.

To do so, first find the values which are given in the question and put it in the formula of point-slope form. Simplify the equation to rewrite as slope-intercept form.

Step 1 of 2

Passing point of the line is (-2,2).

Hence, $x_{1}=-2$ and

$y_{1}=2 \text {. }$

Also, the slope of the line is -2.

Hence, m=-2

Substitute the above values in point-slope form of equation given by $y-y_{1}=m\left(x-x_{1}\right)$

$\begin{aligned}&y-y_{1}=m\left(x-x_{1}\right) \\&y-2=-2(x-(-2) \\&y-2=-2(x+2)\end{aligned}$

Hence, point-slope form of equation given as y-2=-2(x+2).

Step 2 of 2

Solve y-2=-2(x+2) to write it as slope-intercept form given by y=mx+c.

$\begin{aligned}&y-2=-2(x+2) \\&y-2=-2 x-4 \\&y=-2 x-4+2 \\&y=-2 x-2\end{aligned}$

Hence, slope-intercept form of equation is given as y=-2x-2.

Step-by-step explanation:

(49.90)(20%)(6%)

20%= $9.98

49.90+9.98 =59.80

(59.80)(6%)

6%= $3.58

59.80+3.58=63.38
