A car traveling at a rate of 54 miles per hour. What is the car's rate in feet per secondHow many fect will the car travel in 2
Lena [83]

The car's speed in feets per second is 79.2, Hence, it will cover a distance of 158.4 feets in 2 seconds.

Car's speed in miles per hour = 54 miles per hour

Recall :

  • 1 mile = 5280 feets
  • 1 hour = 3600 seconds

Car's rate in feet per second

  • 54 miles per hour = (54 × 5280 × 1/3600) feet per second = 79.2 feets per second.

  • Distance in 2 seconds :
  • Distance = speed × time
  • Distance = 79.2 × 2 = 158.4 feets

Therefore, the car will cover a distance of 158.4 feets in 2 seconds.

If the quadratic formula is used to solve 2x(x + 5) = 4, what are the solutions? {-1/2, -9/2}
ankoles [38]
X²+bx=c
x=[-b+√(b²+4c)]/2

2x(x+5)=4
2x²+10x=4
x²+5x=2

x=[-5+√(5²+4*4)]/2 

if b=-1/2 and c=-9/2
x= {1/2+√[(1/2)²+4*(-9/2)]}/2
