Answer:
see below
Step-by-step explanation:
When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

-Angle AQA' is 60 degrees.
-Triangles ABC and A'B'C' are congruent.
-Angle ABC is congruent to angle A'B'C'. (<em>this is one of the angles of the congruent triangles</em>)
-Segment BC is congruent to segment B'C'
-Segment AQ is congruent to segment A'Q.
Answer:
hope it helps
Step-by-step explanation:
The given inequality is
The sign of inequality is ≤, it means the points on relation line lie in the solution set.
The related equation of the inequality is
At x=0,
At x=1,
Plot the points (0,0) and (1,-2) on a coordinate plane.
The sign of inequality is ≤, it means we have shade below the line.
The point (-2,4) and (3,-6) are in solution set because,
(True)
(True)
Therefore option A is correct.
The points (1,2) and (1,3) are not in the solution set because,
(False)
(False)
<u>Answer:</u>
106 items
<u>Step-by-step explanation:</u>
We know that:
revenues > costs
7.5x – 100 > 79.86 + 5.8x
7.5x - 5.8x > 79.86 + 100
1.7x > 179.86
x > 179.86 / 1.7
x > 105.8
This means that the company will need to sell at least 106 items (the smallest integer greater than 105.8) to make a profit.
The inequality which will determine the number of least items that need to be sold to make a profit is x ≥ 106
Answer:
Step-by-step explanation:
an equation of this tangent is : y = f'(4)(x-a)+f(4)
a = f'(4)
f(x) = - x²
a=4
f'(x) = -2x
f'(4) = -2(4) = -8
f(4) = -(4)² = -16
so : y = - 8 (x-4)-16
y = - 8x +16
