Answer:
I can help with Q "4" as -
It uses triangle congruence test - here we use - SAS, as
one side is equal as it is given
both the angles are 90 degree
and they share a same side
so -
8x = 6x + 5
8x - 6x = 5
2x = 5
x = 2.5
RU = 6x+ 5 = 6 (2.5) + 5 = 20
( I am not so sure but I think this is the answer )
Answer:
The work done is 202.50Nm
Step-by-step explanation:
Given
Required
The work done
First, we calculate the spring constant (k)
So:
The work done using Hooke's law is:
This gives:
Rewrite as:
Integrate
This gives:
Convert to Nm
Yesssssssssssssssssssssssssssssssssssssssssssssssssssssssssss
Answer:
my best advice: look at the y-intercepts!
Step-by-step explanation:
when the equations are set out like this, the last number (in this case "+4" and "-2"), represents where they cross the y axis. this gives you a great place to start.
if you plot (0, 4) for the first equation, you can then move right one square and down one square to get the next point in the equation.
the next one starts with (0, -2) and goes right one square and up two
Answer:
16
Step-by-step explanation:
use the formula (b/2)^2 to find what number to add to each side of the equation
