Answer:

<h2>height=16 cm</h2>

solution

$let \: height \: be \: h \: cm \\ volume \: of \: rectangular \: prism \\ = > \: \: 128 = l \times b \times h \\ area \: of \: base = l \times b \\ = > 8 = l \times b \\ now \\ 128 = 8 \times h \\ \\ or \: h = \frac{128}{8} \\ h = 16 \: cm$

hope this helps....

Answer:

16 cm

Step-by-step explanation:

V= 128 cm³

b= 8 cm²

A line, y = mx + b, passes through the point (10, 3) and is parallel to the line 2x+5y=12.

slava [35]

We have been given that a line $y=mx+b$ passes through the point (10, 3) and is parallel to the line $2x+5y=12$ . We are asked to find the y-intercept of the line.

First of all we will rewrite our given equation in slope-intercept form as:

$2x-2x+5y=12-2x$

$5y=-2x+12$

$\frac{5y}{5}=-\frac{2}{5}x+\frac{12}{5}$

$y=-\frac{2}{5}x+\frac{12}{5}$

We know that slope of parallel lines is equal, so slope of parallel line to our given line would be $-\frac{2}{5}$ .

Now we will use slope-intercept form of equation to find y-intercept.

$y=mx+b$ , where,

m = Slope,

b = The y-intercept.

Let us substitute $m=-\frac{2}{5}$ and coordinates of point $(10,3)$ in above equation as:

$3=-\frac{2}{5}(10)+b$

$3=-2(2)+b$

$3=-4+b$

$3+4=-4+4+b$

$7=b$

Therefore, the y-intercept is 7 and our required equation would be $y=-\frac{2}{5}x+7$ .
