Answer:

a) (0.555, 0) and (6, 0)

b) r = -3 and r = 1.8

c) (0.875, 0.676)

d) (0, 1.235)

Step-by-step explanation:

Set each term in the numerator and denominator equal to 0 and find r.

In the numerator:

r = 7/8, 5/9, or 6

In the denominator:

r = 9/5, 7/8, or -3

Zeros in the numerator that aren't in the denominator are r-intercepts.

Zeros in the denominator that aren't in the numerator are vertical asymptotes.

Zeros in both the numerator and the denominator are holes.

a) (0.555, 0) and (6, 0)

b) r = -3 and r = 1.8

c) Evaluate m(r) at r = 7/8. To do that, first divide out the common term (-8r + 7) from the numerator and denominator.

m(r) = (-9r+5)² (r−6)² / ( (-5r+9)² (r+3)² )

m(⅞) = (-9×⅞+5)² (⅞−6)² / ( (-5×⅞+9)² (⅞+3)² )

m(⅞) = (-23/8)² (-41/8)² / ( (37/8)² (31/8)² )

m(⅞) = (-23)² (-41)² / ( (37)² (31)² )

m(⅞) = 0.676

The hole is at (0.875, 0.676).

d) Evaluate m(r) at r = 0.

m(0) = (-9×0+5)² (0−6)² / ( (-5×0+9)² (0+3)² )

m(0) = (5)² (-6)² / ( (9)² (3)² )

m(0) = 1.235

The m(r)-intercept is (0, 1.235).

The equation of a hyperbola is $x^{2}$ /9 - $y^{2}$ /4 = 1

What are the steps to Hyperbola equation ?

To find the equation of hyperbola, the following steps must be taken. You need to identify;

The coordinate of the center

The coordinate of the vertices

The coordinate of the foci

The general equation of a hyperbola can be expressed as

$x^{2}$ / $a^{2}$ - $y^{2}$ / $b^{2}$ = 1

From the graph, we have the following parameters

a = 3

$a^{2}$ = $3^{2}$ = 9

b = 2

$b^{2}$ = $2^{2}$ = 4

The equation of a hyperbola can be expressed as

$x^{2}$ /9 - $y^{2}$ /4 = 1

The vertices = V(+/-a,0) = (+/-3,0)

The center = C(0,0)

The focus = F(+/-C, 0)

Where $C^{2}$ = $a^{2}$ + $b^{2}$

C = $\sqrt{9 + 4}$

C = $\sqrt{13}$

Focus = F(+/- $\sqrt{13}$ , 0)

The general equation for asymptote = +/- b/a X

= +/-2/3X

Therefore, the equation of a hyperbola can be expressed as

$x^{2}$ /9 - $y^{2}$ /4 = 1

Find the perimeter and area of length 3cm and width 5 cm

Anni [7]

L = 5 and w = 3

Perimeter = 2(l + w)
P = 2(5 + 3)
P = 2(8)
P = 16 cm

Area = l*w
Area = 5*3
Area = 15 cm^2
