Answer:
THe answer is D
Step-by-step explanation:
The graph shows that x never becomes < 0. In other words the point (-1,0) is not part of the graph. So D is your only answer.
Answer:
Option D is correct.
Step-by-step explanation:
Given: A graph.
We know that The domain of a function is the complete set of possible values of the independent variable.
From given graph x is independent variable.
Generally Domain for the Square root function is all non negative real numbers.
So, from given graph and general domain.
Domain of given graph = x ≥ 0
Therefore, Option D is correct.
x = r sin θ cos Ф
x² = r² sin² θ cos² Ф
y = r sin θ sin Ф
y² = r² sin² θ sin² Ф
z = r cos θ
z² = r² cos² θ
x² + y² + z²
= r² sin² θ cos² Ф + r² sin² θ sin² Ф + r² cos² θ
= r² sin² θ (cos² Ф + sin² Ф) + r² cos² θ
= r² sin² θ + r² cos² θ
= r² (sin² θ + cos² θ)
= r² √
The number of people rides the Ferris wheel in 2 hours is 270.
The basic explanation of multiplication is adding a number, with respect to another number, repeatedly.
Given, Ferris wheel can accommodate 54 people in 24 minutes
number of people can ride in 1 minute = 54/24
number of minute in 2 hours is 2 x 60 = 120 minutes
no. of people can ride in 2 hours or 120 minutes is
54/24 x 120 = 270
Hence, the 270 people could ride the Ferris wheel in 2 hours.
