Simplify (0.00243)^-2/5 x (0.0009)^1/2

   (0.00243)^-2/5 x (0.0009)^1/2

= (243/100000)^-2/5 x (9/10000)^(1/2)

= ((3/10)^5)^-2/5 x ((3/100)^2)^(1/2)

= (3/10)^-2 x (3/100)

=1/(3/10)^2 x (3/100)

= (100/9) x (3/100)

= (1/3)

Hope this helps!

1/3

Step-by-step explanation:

(0.00243)^-2/5 x (0.0009)^1/2

= 1/(0.00243)^2/5 x (0.0009)^1/2

= 1/0.3² × 0.03

= 1/0.09 × 0.03

= 1/3

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
