Answer:
Step-by-step explanation:
Ok I cannot see the figure but let me explain to you how to do this. If you see the and know the measurments, just divide all the measurements by 3 and draw the figure again. If I have a rectangle with side lengths 12 and 9, and I want to draw a 1/3 scale drawing, I would divide 12/3 = 4 and 9/3 = 3. So your new sidelengths are 4 and 3. I hoped this helped a little!!
Answer:
x=7
Step-by-step explanation:
3(2x - 5) = 9(10 - x)
6x-15=90-9x
6x+9x=90+15
15x=105
x=7
Answer:
b
Step-by-step explanation:
thats funny i just did that
Given:
The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by:

To find:
The current that will produce the maximum power.
Solution:
We have,

Here, leading coefficient is negative. So, it is a downward parabola.
Vertex of a downward parabola is the point of maxima.
If a parabola is
, then

In the given function, a=-12 and b=120. So,



Putting x=5 in the given function, we get




Therefore, 5 watt current will produce the maximum power of 300 amperes.
I hope this helps you
