Answer:
46°
Step-by-step explanation:
Same number of rows to chairs in a row would form a square.
Use the total number of students as the area
Find the number or rows by taking the square root of student:
The square root of 7033 is 83.86
Round up to 84
Total seats would be rows x seats per row:
84 x 84 = 7,056 total seats
7056 seats - 7033 students = 23 empty seats
Let y = the length of the 3rd side
x+3 + 2x+4 + y = 6x
x + 2x + 3 + 4 + y = 6x
3x + 7 +y = 6x
7 + y = 3x
y = 3x - 7
The length of the third side in terms of x is 3x-7
ANSWER
EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form
where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.
Answer:
d = 7, 3
Step-by-step explanation:
First, you need to isolate the absolute value
-3|d - 5| = -6
divide both sides by -3:
|d - 5| = 2
break into 2 equations:
d - 5 = 2, d - 5 = -2
solve both equations and collect solutions:
d = 5 + 2, d = 5 - 2
d = 7, 3
