Abd is a right angled triangle so by pythagoras we know
and to calculate h we need to use the sine rule
i hope this helps
The equation line passing through a point is understood to be parallel to the x-axis. In this case, the equation should be expressed as y = b where b is any number. Since y = 14 in the point (1,14), the equation of horizontal line passing through this point is y = 14.
Answer:
x + 7у = 23 3х + 14у = 48
Step-by-step explanation:
x + 7у = 23 3х + 14у = 48
You take the 4% and multiply that by eight then you get 0.32 and you multiply that by 1000 and you get 320.00
We have that
x²<span> + 7x + c
</span><span>Group
terms that contain the same variable
</span>(x² + 7x )+ c
<span>Complete
the square. Remember to balance the equation
</span>(x² + 7x+3.5² )+ c-3.5²
Rewrite as perfect squares
(x+3.5)²+ c-3.5²
so
c-3.5² must be zero
c-3.5²=0------- c=3.5²------> c=12.25
the answer isthe value of c must be 12.25
