Step-by-step explanation:
first you have to figure out how much room is in the classroom
then you are going to have measure 2 mters apart of each table
Answer: 10
Step-by-step explanation:
See the attached figure to better understand the problem
we know that
in the triangle ABC
tan(alfa/2)=AC/BC----> 5/3
so
(alfa/2)=arctan (5/3)---------> 59.0362°
alfa=2*59.0362--------> alfa=118.07°
alfa+beta=180°----------> because are supplementary angles
beta=180-118.07-------> beta=61.93°
the answer is
the angles are
alfa=118.07°
beta=61.93°
Answer:
Yes, the following equation is a quadratic function in vertex form
Step-by-step explanation:
we know that
The <u>quadratic function</u> of the vertical parabola into <u>vertex form</u> is equal to
where
(h,k) is the vertex of the parabola
If the <u>coefficient</u> a is > 0 ----> the parabola open upward (vertex is a minimum)
If the coefficient a is < 0 ----> the parabola open downward (vertex is a maximum)
in this problem we have
The <u>squared term</u> contain the x-coordinate of the vertex
The <u>constant term</u> is the y-coordinate of the vertex
The vertex is the point (2,6)
The coefficient is equal to
----> open upward (vertex is a minimum)
