Answer:
the domain is equal to all real numbers greater than or equal to 0
Step-by-step explanation:
The domain is all the numbers in which the graph reaches in regards to the x axis
We can see from the graph that it starts at 0 and then moves right
THis means that the domain is equal to all real numbers greater than or equal to 0
x = 30°.
The triangle drawn inside the circle is an equilateral and equiangular triangle which means that its three sides and its internal angles (that measure 60°) are equal.
To find x°:
First, we can see from the image that the tangent line to circle with arrows is formed a right angle, the angle of one side of the equilateral triangle, and the angle formed with the other side of the equilateral triangle, this three angles has to form 180° respect to the tangent line:
90° + 60° + y° = 180°
y° = 180° + 150°
y° = 30°
Second, the line in the right side of the equilateral triangle form an angle of 180°, so:
60° + z° = 180°
z° = 180° - 60°
z° = 120°
Finally, the triangle formed by this lines its internal angles are x°, y°, and z° and its sum is 180°, then:
x° + y° + z° = 180°
x° + 30° + 120° = 180°
x° + 150° = 180°
x° = 180° - 150°
x° = 30°
Answer:
54 Minutes
Step-by-step explanation:
45 minutes/5 walls/4 people=2.25 minutes per person per wall
2.25 times 6 times 4=54 minutes
Answer:
Step-by-step explanation:
Given the equation
This equation consists of two parts. In the left part, there is a logarithmic function
In the right part, there is a linear function
To solve the equation graphically, you have to plot the graphs of these two functions and find the point of intersection of these graphs.
Hence, appropriate system is
Answer:
12 years and 36 years
Step-by-step explanation:
Woman -- 3x
Daughter -- x
12 years later, (3x + 12) and (x + 12)
Therefore,
3x + 12 = 2(x + 12)
3x + 12 = 2x + 24
x = 24 -12
x = 12
Daughter -- 12 years
Woman -- 36 years
Thenks and mark me brainliest :)
