Answer:
D) Vertex = (0,-1), y-intercept = (0,-1), x-intercepts = (-3,0) and (3,0), axis of symmetry is x = 0
Step-by-step explanation:
The vertex is the y-intercept. Its coordinates are (0, -1).
The axis of symmetry is the vertical line through the vertex. Its equation is x=0.
These observations are sufficient for you to choose the correct answer (D).
Answer: x=0 hope this helps
Answer:
Force, F = 68.93 pounds
Step-by-step explanation:
Given that,
Mass of the astronaut, m = 80.70 kg
Acceleration due to gravity on Mars,
The force acting on him is given by using second law of motion as :
F = 306.66 N
Since, 1 newton = 0.224 pound
F = 306.66 N = 68.93 pounds
So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.
Answer:
3*45=135 minutes.
Step-by-step explanation:
Hello there!
Start by seeing if there is an equal rate in the qmount of people that we are working with.
27/9=3 (so there's one)
3*45 (the amount of time when 9 people are in line)= 135 minutes
Have a great day!
