If f(x) = 1/9 x - 2, what is f-1 (x)

1 answer:

$f(x) = \frac{1}{9} x - 2 \\$

$f( - 1) = \frac{1}{9} ( - 1) - 2 \\$

$f( - 1) = - \frac{1}{9} - 2 \\$

$f( - 1) = - \frac{1}{9} - \frac{18}{9} \\$

$f( - 1) = - \frac{19}{9} \\$

Step-by-step explanation:

∠B = arcsin(b·sin(A)a)

= 0.67513 rad = 38.682° = 38°40'56"

∠C = 180° - A - B = 0.89566 rad = 51.318° = 51°19'4"

c = a·sin(C)sin(A) = 31.22499

Jamie says that if she knows only the measure of one angle in an isosceles triangle, she can always determine the measures of th

lozanna [386]

Answer:

Jamie is correct

Step-by-step explanation:

Jamie is correct.

Example: isosceles triangle ABC AB=AC

∠B = ∠C ∠A + ∠B + ∠C = 180°

if ∠A = x ∠B = ∠C = 1/2 * ( 180° - x)

if ∠B or ∠C = x ∠A = 180° - 2x

The radius,r , of a sphere is 4 . 3m Calculate the sphere's volume,v . Use the value 3.14 for sqaure, and round your answer to t

kotykmax [81]

Answer:

V(s) = 332,9 m³

Step-by-step explanation:

The volume of a sphere is:

V(s) = (4/3)*π*r³

if we know r = 4,3 m then

V(s) = (4/3)*3,14*(4,3)³

V(s) = 332,8693 m³

Rounding the answer to the nearest tenth

V(s) = 332,9 m³
