Im need help cos(θ) = x / R tan(θ) = y / x sec(θ) = R / x sin(θ) = y / R cot(θ) = x / y CSC(θ) = R / y
R = √(x2 + y2)

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

many reason,

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

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
