not too sure but i think it’s right

Answer:
distance = 1.5 miles(approx.)
Step-by-step explanation:
given,
speed of sound = 1130 ft/s
1 ft = 0.3048
1130 ft/s = 0.3048 × 1130 m/s
= 344.424 m/s
time = 7 second
distance = speed × time
distance = 344.424 × 7
distance = 2410.968 m
1 m = 0.0006214 miles
2410.968 m = (0.0006214 × 2410.968) miles
distance = 1.498 miles
distance = 1.5 miles(approx.)
Answer:
x = 5/2
y = -2
Step-by-step explanation:
(1+i)² (x+yi) = 4+5i
(1+2i+i²)(x+yi) = 4+5i
(1+2i-1)(x+yi) = 4+5i
2i(x+yi) = 4+5i
2i²y + 2xi = 4+5i
-2y + 2xi = 4 + 5i
By comparing both sides,
-2y = 4
y = -2,
2x = 5
x = 5/2
