This equals to 10% of the surveyed people which are 50 people
Since the radius for either the quarter or the whole circle is the same the radius of the circle shall be divided into 4 parts
Please refer to the photograph to know more about the answer
Answer:
(4x -3yi) (4x+3yi)
Step-by-step explanation:
We have a^2 + b^2
Over the complex number, this is equal to
(a-bi) (a+bi)
(4x -3yi) (4x+3yi)
The correct statement are the first and the second
=======================================
The first statement:
y = (-2/3) x - (13/3)
slope = -2/3 and passing through (4,-7) because (-2/3) *4 - (13/3) = -7
the slope of the parallel line = -4/6 = -2/3
============================================================
The second statement
y = (-7/2) x - (5/2)
slope = -7/2 and passing through (-3,8) because (-7/2) *-3 - (5/2) = 8
the slope of the perpendicular line = 2/7
the multiplication of the two slopes = -7/2 * 2/7 = -1
============================================================
The third is false
because the lines are parallel not perpendicular
the fourth is false
because the lines are perpendicular not parallel
1) So writing in terms of x, we have: y=30,000-2000x or f(x) = -2000x +30,000
Hence, the y intercept is the point 30,000 ( 0, 30000) and the slope is -2000 for it is a decreasing function.
2) Identifying the variables we have, setting a table
