Answer:
Last option
Step-by-step explanation:
<em>the unit rate is 0.8x per unit y</em>
<em></em>
the proportional relationship is y =
this means that the constant of proportionality k = = 0.8
re-writing, we have
<em>y = 0.8x</em>
<em>therefore, the unit rate is 0.8x per unit y</em>
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here equation is
x²−8x+y²+2y=5
Changing in to (x-h)²+(y-k)² = r² form
x²−8x + 16 - 16 +y²+2y+1 - 1=5
(x-4)² - 16 + (y+1)² -1 = 5
(x-4)² + (y+1)² = 22
(x-4)² + (y+1)² = 4.69²
Center is (4,-1) and radius is 4.69
Stella is correct about center and wrong about radius
Cosec <F = 73/55
In ΔEFG, the measure of ∠G=90°, GF = 48, EG = 55, and FE = 73. What ratio represents the cosecant of ∠F?
First you must know that;
Cosecant <F = 1/sin<F
Given
∠G=90°, GF = 48, EG = 55, and FE = 73.
ED ,= hyp = 73
EG = opp = 55*side facing <F
Using DOH CAH TOA
Sin theta = opp/hyp
Sin <F= 55/73
Reciprocate both sides
1/sinF = 73/55
48
{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}
(x, y)
Domain = x
Range = y
Domain = (3, 6, -1, 5, -4)
In case you need the range it is (-2, 1, 4, 9, 0).
Answer: (3, 6, -1, 5, -4)
Hope this Helps!!
