Answer:
58.995 round to the nearest whole number is 59 miles per hour
Step-by-step explanation:
1 kilometer/hr = 0.62 miles per hour
Therefore 100 km/hr = 100 × 0.621
= 62 miles per hour
95 km/hr = 95 × 0.621
= 58.995 miles per hour
58.995 round to the nearest whole number is 59 miles per hour

Answer: x = f/k + 1
Step-by-step explanation:
Answer:
x = 2 ± 2 sqrt(5)i
Step-by-step explanation:
(x – 2)^2 + 20 = 0
Subtract 20 from each side
(x – 2)^2 + 20 -20=0 -20
(x – 2)^2 =- 20
Take the square root of each side
sqrt((x – 2)^2) =±sqrt(- 20)
x-2 = ±sqrt(- 20)
We know sqrt(ab) = sqrt(a) sqrt(b)
x-2 = ±sqrt(- 1) sqrt(20)
We know the sqrt (-1) = i
x-2 = ±i sqrt(4*5)
x-2 = ±i sqrt(4) sqrt(5)
Add 2 to each side
x-2+2 = 2 ±i sqrt(4) sqrt(5)
x = 2 ±i 2 sqrt(5)
x = 2 ± 2 sqrt(5)i
