Answer:
D sqrt( A ) sqrt(pi) / pi = r
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
To find r
Divide each side of the equation by pi
A / pi = pi r^2 /pi
A / pi = r^2
Take the square root of each side
sqrt(A / pi )= sqrt( r^2)
sqrt(A / pi )= r
We do not like leaving square roots in the denominator, so multiply by sqrt(pi)/sqrt(pi))
sqrt(A / pi ) *sqrt(pi)/sqrt(pi))
sqrt( A ) sqrt(pi) / pi = r
Step-by-step explanation:
Angle 1 2 and 3 are angles that are in a triangle and all the angles in a triangle always add up to 180
so <1 +<2 +<3=180
Hope that helps :)
Answer:
10
Step-by-step explanation:
2 divided by 0.5 is 4 and 3 divided by 0.5 is six so the answer is 10
Here is how to find the answer for this problem.
We know that the formula for getting the area of the rectangle is A = Length x Width. Given that the area is 37.5 inches squared and the length is 15 inches, let us just plug in the values. Let w be width.
35.7 in^2 = 15 in x w
Next, we divide both sides by 15 and this is the result
w = 2.5 inches.
Therefore, the answer would be 2.5 inches.
Hope this answer helps. Thanks for posting your question.
Step-by-step explanation:
B: The x axis is the horizontal one. If we look at the graph, there are actually two spots where the line crosses the x axis. It looks to be between -2 and -1 as well as 1 and 2
D: For vertical parabolas such as this, the axis of symmetry is the x coordinate of the vertex. The vertex is essentially the middle point, that, for this graph, is at the bottom. The axis of symmetry is x=0 as that is the x coordinate of the vertex.
E: f(x), in 2D graphs, is typically y, as is the case here. As this parabola opens upward, the minimum point is the vertex, which seems to be -3 for this graph. As the graph seems to be x²-3 or something like that, there is nothing limiting x from being infinity, and when x is equal to infinity in this function, y is as well. Thus, the maximum is infinity.
