Find the sum and product of the roots of each equation of <img src="https://tex.z-dn.net/?f=2x%5E%7B2%7D" id="TexFormula1" title

vlada-n [284]

Answer: Sum (b) = -4

Product (c) = 4

<u>Step-by-step explanation:</u>

In the quadratic equation ax² + bx + c

b represents the sum of the roots
c represents the product of the roots

2x² - 8x + 8 = 0

2(x² - 4x + 4 = 0)

↓ ↓

b= -4 c= 4

Through: (2,5), perp. to y =- 2/3x +3

chubhunter [2.5K]

Find the equation of line passes through point (2, 5) and perpendicular to line having equation y =- 2/3x +3

<h3><u>Answer:</u></h3>

The equation of line passes through point (2, 5) and perpendicular to line having equation y =- 2/3x +3 in slope intercept form is $y = \frac{3}{2}x + 2$

<h3><u>Solution:</u></h3>

Given that line passes through (2, 5) and perpendicular to line having equation $y = \frac{-2}{3}x + 3$

Let us first find slope of original line

<em><u>The slope intercept form of line is given as:</u></em>

y = mx + c ------ eqn 1

Where "m" is the slope of line and "c" is the y - intercept

On comparing the slope intercept form y = mx + c and given equation of line $y = \frac{-2}{3}x + 3$ we get

$m = \frac{-2}{3}$

Thus slope of given line is $m = \frac{-2}{3}$

We know that product of slopes of given line and slope of line perpendicular to given line is always -1

Slope of given line x slope of line perpendicular to it = -1

$\begin{array}{l}{\frac{-2}{3} \times \text { slope of line perpendicular to it }=-1} \\\\ {\text { slope of line perpendicular to it }=\frac{3}{2}}\end{array}$

Let us find equation of line with slope $m = \frac{3}{2}$ and passes through (2, 5)

Substitute $m = \frac{3}{2}$ and (x, y) = (2, 5)

$5 = \frac{3}{2} \times 2 + c\\\\5 = 3 + c\\\\c = 2$

<em><u>Thus the required equation of line is:</u></em>

Substitute $m = \frac{3}{2}$ and c = 2 in eqn 1

$y = \frac{3}{2}x + 2$

Thus the equation of line perpendicular to given line is found out

lilavasa [31]

Answer:

575.8 cubic cm

Step-by-step explanation:

V(cone) = 1/3· π · r² · h

V = 1/3 · π · 25 · 12

V = 4(25)π or 100π = 314

V(half-sphere) = (4/3 · π r³)/2

V = (4/3π · 125) = 261.8
