b- the 50% markdown is taken off the marked up price
Answer:
A ) 6
Step-by-step explanation:
The formula for Average rate of change is:
Aroc = change in y / change in x.
Aroc = y2-y1 / x2 - x1
The first point will be (x1,y1), and second will be (x2,y2).
x1 is 0, and when the x value is at 0, the y value is at -7, so the coordinate point is (0, -7).
For the second point, x = 2, and the corresponding y value is 5. So you just simpliy plug everything into the formula to find AROC:
= 5 - (-7) / 2 - 0
= 12 / 2
= 6
Answer:36.23
Step-by-step explanation:
No, they forgot to switch variable labels after solving for the independent variable...
y=-8x+4
y-4=-8x
(y-4)/-8=x
Now that you have solved for the independent variable x, you switch the variable labels...
y=(x-4)/-8
f^-1(x)=(x-4)/-8 which should really be rewritten as:
f^-1(x)=(4-x)/8 :P
Answer:
Step-by-step explanation:
Here, the region of the triangle with a base 4 cm and a level 3 cm.
That is, the region of a triangle=
1/2 × Base × Level
=1/2 × 4 × 3
=6 sq cm
The region of a square shape with a length 5 cm and a breadth 4 cm
The region of a square shape = Length × breadth
=5 × 4 =20 sq cm
The region of a square shape with a length 4 cm and a width 3 cm
=4 × 3 =12 sq cm
The region of a square with the side 4 cm.
The region of a square = side²=4²=16 sq cm
The absolute surface of the given polyhedron =6 + 6 + 20 + 12 + 16
=60 sq cm
From the above estimation, it is distinguished as a region of the triangle that is determined incorrectly.
