Answer:
y = 57
Step-by-step explanation:
y α x
y = kx ; k = Constant of proportionality
81 = k* 54
k = 81/54
k = 1.5
Value of y when x = 38
y = kx
y = 1.5 * 38
y = 57
Hence, y = 57 when x = 38

Answer:
d=5.656854
Step-by-step explanation:
d=√ ( 4 − 8 ) 2 + (− 7 − (− 3 ) ) 2
d=√ ( − 4 ) 2 + ( − 4 ) 2
d= √ 16 + 16
d= √32
d=5.656854

Answer:
π/4 radians
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle (in radians).
Here, r = 8 inches and s = arc length = 2π inches. We need to find the central angle, Ф. The formula given above is s = rФ, or, equivalently,
Ф = s/r.
Here, the central angle is Ф = s/r = 2π/8, or π/4 radians.
