Answer:
The answer is: Yes
Step-by-step explanation:
1. Substitute the 2's for the x's.
2. Substitute the 3's for the y's
3. You get 4-9= -5
4. Do the same for the second problem.
5. 8-12= -4
6. Both problems are correct once the substitutions are made, therefore the answer is "Yes".
20 and 2/3 is correct, I think
Find area
area=pir^2
d/2=r=50/2=25
A=pi25^2
a=pi625
aprox pi=3.141592
a=1963.495
that is how many square feet
multiply that by 120
1963.495 times 120=$235,619.4
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.
9 muffins per hour because 48 minus three is 45 . 45 divides by five is 9
