Answer:
To find the cube root of a number is a bit more complicated and in our days is considered impractical, but here is a method explained. Look at the 2nd example scrolling down about 1/3 of the page
If you want to know the concept of square roots and cube roots ?
the square root of a number is that number which when multiplied by itself two times gives us that number
e.g.
√64 = x , so that (x)(x) = 64
and from our multiplication table we know that
(8)(8) = 64 , so that
√64 = 8
the cube root of a number is that number which when multiplied by itself three times gives us that number
e.g.
∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64
so ∛64 = 4
for 9 I wrote Any decimal which terminates is rational
any decimal which has a repeat is rational
any decimal which does not show any repeating decimals and which is never-ending is irrational
Step-by-step explanation:
Answer:
x > - 4
Step-by-step explanation:
Given
6x - 5 > - 29 ( add 5 to both sides )
6x > - 24 ( divide both sides by 6 )
x > - 4
Answer:
Step-by-step explanation:
A: true. Her graph goes 4 units up.
B: False. His graph goes 4 units to the left. Be sure you check this answer out.
C: True. It moved from (0,0) to (0,4)
D: Victor's graph move left in the minus direction. False.
E. True. See C.
Answer:
All except from point E's y-coordinate (which is -1.5 (found it through the equation y=-1.5 and trying to see if these coordinates are solutions to the above equation) All the others are integers, which you can find through aligning the point on the axis of the chosen (y or x) coordinate.
Step-by-step explanation:
Point C has -2 x-coordinate since it is on the x=-2 line
Similarly, point D has -2 y coordinate,
point E has 2 x-coordinate and -1,5 y-coordinate
and point F , since it's the two axis' common point has coordinates of (0,0).
Hope I helped! Further explanation can be given on request on your behalf.
Mid point elasticity formula
[change in price] / [average price] ÷ [change in quantity] / [average quantity]
change in price = $6 - $4 = $2
average price = [$ 6 +$4] / $2 = 10/ 2 = 5
[change in price] / [average price] = 2/5
change in quantity = 1000 boxes - 600 boxes = 400 boxes
average quantity = [1000 boxes + 600 boxes] / 2 = 1600 boxes / 2 = 800
boxes
change in quantity / average quantity = 400/800 = 1/2
midpoint elasticity = 2/5 ÷ 1/2 = 4/5 = 0.8
0.8 < 1 => inelastic demand (the change is demand is less than proportional to the change in price)
