Answer:
period = 2
Step-by-step explanation:
The period is the measure of 1 complete cycle of the wave
The wave enters at x = 0 , y = - 0.5
After 1 cycle the wave is at x = 2, y = - 0.5
period = 2 - 0 = 2
Answer:
4096
Step-by-step explanation:
<em><u>Simplify:</u></em>
=((−4)3)2
=((−4)3)*((−4)3)
=((−4)*(−4)*(−4))*((−4)*(−4)*(−4))
=(−4)*(−4)*(−4)*(−4)*(−4)*(−4)
=(−4)6

Answer:
It will measure 75 millimetres on the plan.
Step-by-step explanation:
Given:
Scale on the plan = 1:100
Length of the fence = 7,500 mm
To find:
how many millimetres will it measure on the plan
Solution:
As the ratio on the plan is 1: 100, the for 7500 the ratio will
x : 7500
Now by cross multiplication we get
x = 75
The x-coordinates need to be subtracted and the y-coordinates need to be subtracted.
The x-coordinates are 6 and 2.
Their subtraction is 6 - 2.
Kendra did this correctly.
The y-coordinates are 8 and -3.
Their subtraction is 8 - (-3) = 8 + 3 = 11.
Kendra did this incorrectly. She should have had 8 - (-3) = 8 + 3 = 11.
Then she'd square 11.
Instead, she subtracted 8 and -3 incorrectly and got 8 - 3 = 5.
Then she squared 5 when she should have squared 11.
