Answer:
EF = 7 units
AD = 3 units
BC = 11 units
Step-by-step explanation:
Since it is an isosceles trapezoid and the midsegment is x, the sum of the bases divided by 1/2 is the value of the midsegment, x.
x = 1/2(x-4 + 2x-3)
x = 1/2x - 2 + x - 1 1/2
x = 1 1/2 x - 3.5
-1/2 x = -3.5
x = 7 units
EF = 7 units
AD = 7-4 = 3 units
BC = 2(7) - 3 = 11 units
Answer:
Inverse of f(x)
Step-by-step explanation:
<u> Explanation</u>:-
<u>Step(i)</u>:-
Given the function
Given function is one-one and onto function
Hence f(x) is bijection function
now cross multiplication, we get
( 8+x)y = 3 x
8 y + x y = 3 x
8 y = 3 x - x y
taking Common 'x' we get
x (3 - y) = 8 y
<u><em>Step(ii)</em></u>:-
The inverse function
The inverse function of x
<u><em>Final answer</em></u>:-
Inverse of f(x)
Step-by-step explanation:
A = 12.25cm2
P perimeter 14cm
<span>-ends of diameter: (-17,-9) & (-19,-9)
-- The distance between the ends of the diameter is 2,
so the radius is 1.
-- The center of the circle is the midpoint of the diameter ... (-18, -9) .
<em> (x+18)² + (y+9)² = (1)²</em>
-ends of diameter: (-3,11) & (3,-13)</span>
<span>-- The distance between the ends of the diameter is √612,
so the radius is (1/2) √612 = √153 .
-- The center of the circle is the midpoint of the diameter ... (0, -1) .
<em> (x)² + (y+1)² = 153</em></span>
