Answer:
Three points are: (-2,0) , (0,1) , (2,2)
Step-by-step explanation:
Given: -x+2y=2
Put x=0 into -x+2y=2
2y=2
y=1
Point: (0,1)
Put x=-2 into -x+2y=2
2+2y=2
y=0
Point: (-2,0)
Put x=2 into -x+2y=2
-2+2y=2
y=2
Point: (2,2)
Three points are: (-2,0) , (0,1) , (2,2)
Plot the points on graph and join them.

The magnitude of a right angle is 90°.
we are asked to find a fraction of 90°.
one sixth as a fraction is 1/6.
therefore to find 1/6th of a right angle we can calculate as follows
1/6 of 90
when we have the 'of' function it means to multiply
numerators are multiplied by numerators and denominators multiplied by denominators
angle is 15°
therefore 1/6th of right angle is 15°

Answer:
La elevación de la carretera es de aproximadamente 0.999 metros.
Step-by-step explanation:
Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:
La elevación de la carretera se determina mediante la función seno:
(1)
Donde:
- Elevación de la carretera, medida en metros.
- Longitud de la carretera, medida en metros.
Si sabemos que y
, entonces la elevación de la carretera es:
La elevación de la carretera es de aproximadamente 0.999 metros.
