What is the equation of the graph below? On a coordinate plane, a curve crosses the y-axis at y = 1. It has a maximum of 1 and a minimum of negative 1. It goes through 1 cycle at 5 pi. y = cosine (StartFraction x Over 0.4 EndFraction) y = cos(5x) y = cos(0.4x) y = cosine (StartFraction x Over 5 EndFraction)

range is infinite on both x and y axis positive and negative

step-by-step explanation:

the answer is 13 cm

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
