Answer:
Step-by-step explanation:
t=(-2.74 + sqrt(2.74^(2)-4*-4.9*(-10))) / -2*-4.9
t=(-2.74 + sqrt(7.5076-4*+49))/9.8
t=(-2.74 + sqrt(7.5076+45))/9.8
t=(-2.74 + sqrt(52.5076))/9.8
t=(-2.74/9.8)+(sqrt(52.5076))/9.8
this is simplest form, next will be rounded answers
t=0.45981763305
Step-by-step explanation:
- 1⅔ < -¼

Answer:
Height of rectangular prism = 11 inches
Step-by-step explanation:
Given that:
Volume of rectangular prism = 572 cubic inches
Length of prism = 4 inches
Width of prism = 13 inches
Volume of prism = Length * Width * Height
572 = 4 * 13 * h
572 = 52h
52h = 572
Dividing both sides by 52

Hence,
Height of rectangular prism = 11 inches
Jenny won the race as she finished the race much more quickly and has greater average speed than Lester.

Jenny: distance/time = 100/15.2 = 6.58 m/s = 6.6 m/s
Lester: distance/time = 100/15.7 = 6.37 m/s = 6.4 m/s
