1. Obtén la pendiente de las siguientes rectas, grafícalas y determina si las rectas L1 y L2, cuyas ecuaciones son 3x+4y-2=0 y 3x+4y+6=0, son paralelas o no.
Answers
Queremos obtener la pendiente de dos lineas dadas, y en base a eso, determinar si son paralelas o no.
Las pendientes son para ambas lineas igual a -3/4, como ambas lineas tienen la misma pendiente y diferente ordenada al origen, podemos concluir que son paralelas.
-----------------------------
Una línea en general se escribe como:
y = a*x + b
Donde a es la pendiente y b es la ordenada al origen.
En este problema se nos dan las líneas:
3*x + 4*y - 2 = 0
3*x + 4*y + 6 = 0
Comencemos por reescribir esas líneas en la forma más general, para hacer esto, debemos aislar y en ambas ecuaciones:
y = (-3/4)*x + 2/4
y = (-3/4) - (6/4)
Aqui podemos ver que ambas pendientes son iguales a -3/4
Al final de la respuesta puedes ver el gráfico de ambas líneas.
Como ambas líneas tienen la misma pendiente, pero distintas ordenadas al origen, podemos concluir que son paralelas.
Esto mismo se puede observar en el gráfico de abajo.

Jackson is starting an exercise program.The first day he will spend 30 minute on a treadmill by 2 minutes each day.Write an equation for t(d),the time,in minutes,on the treadmill on day d
Answers
Answer:
For the d day Jackson exercised for t(d)= 30 + 2d where d is the number of day.
t(d)= 30 + 2d
Step-by-step explanation:
Let the total time on the treadmill be given by y each day and let x take the values of number of the days exercised . For the first day x= 0 and so on.
Therefore
For the first day Jackson exercised for 30 minutes
y= 30 + 2x
y= 30 + 2(0)
y= 30 minutes
For the second day Jackson exercised for (x=1) 32 minutes
y= 30 + 2x
y= 30 + 2(1)
y= 32 minutes
For the third day Jackson exercised for (x=2) 34 minutes
y= 30 + 2x
y= 30 + 2(2)
y= 34 minutes
For the fourth day Jackson exercised for (x=3) 36 minutes
y= 30 + 2x
y= 30 + 2(3)
y= 36 minutes
For the d day Jackson exercised for (x=d) 30 + 2d where d is the number of day.
y= 30 + 2x
y= 30 + 2(d)
y= 30 + 2d

What is the volume of a hemisphere with a radius of 4.9 ft, rounded to the nearest
tenth of a cubic foot?
Answers
The volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.
Hemisphere
A hemisphere is gotten when a sphere is cut into two equal halves.
The volume of a hemisphere is expressed as;
V = (2/3)πr³
Where r is the radius and π is pi ( π = 3.14 )
Given the data in the question;
Radius of the hemisphere r = 4.9ftVolume of the hemisphere V = ?To determine the volume of the hemisphere, we substitute our values into the expression above.
V = (2/3)πr³
V = (2/3) × π × (4.9ft)³
V = (2/3) × π × 117.649ft³
V = 246.4ft³
Therefore, the volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.
