Answer:
A. 2.3 sec and 5 sec
Step-by-step explanation:
We are given that start from 110 feet away, a person on a bicycle rides towards a checkpoint and then it passes it. the rider is traveling at a constant rate of 30 feet per second.
The distance between the bicycle and the checkpoint is given by the equation :
Now we are required to calculate at what times is the bike 40 feet away from the checkpoint. So, substitute d = 40 in the equation
and 
and 
and 
and 
and 
Hence at 2.3 sec and 5 sec the bike is 40 feet away from the checkpoint.
... is the length of the line perpendicular to the given line that also passes through the given point.
Answer:
El reloj está marcando:
las 4:00 horas
Step-by-step explanation:
El reloj avanzó a su mismo ritmo pero en sentido contrario a partir de las 6:45
si ahora son las 9:30 el reloj marca:
9:30 = 9horas 30minutos = 9h 30'
6:45 = 6horas 45minutos = 6h 45´
1 hora = 60'
9h 30' = 8h + 60' + 30' = 8h + 90' = 8h 90'
entonces:
8h 90'
- 6h 45'
= 2h 45
entonces el reloj está marcando 2h 45' menos que la hora en que se dañó.
por tanto:
6h 45'
- 2h 45'
= 4h 00'
El reloj ahora está marcando las
4 horas en punto.
Answer:
y= $50x + $25
Step-by-step explanation:
Slope-intercept form is y=mx+b
x is something that is constant
b is something you add on to the constant
