Explanation:</h2>
Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:
So we need to find the entire interval at which this function positive. Put another way:
By using graphing tool, we get the graph shown below. As you can see:
- The function decreases from
- The function increases from
- The graph of the function is a parabola that opens up.
But what is really importan in this problem is that:
- The function is positive over the interval
At this interval the function is positive, that is,

Answer:
2 sqrt(13)
Step-by-step explanation:
We can find the hypotenuse using the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
4^2 + 6^2 = c^2
16+36 = c^2
52 = c^2
Taking the square root of each side
sqrt (52) = c
sqrt(4*13) = c
2 sqrt(13) = c
Answer:
A+6+A = 20
A = 7
Step-by-step explanation:
J = number of problems Juana completed
A = number of problems Andy completed
J+A=20
J = A + 6
Replace J with A+6 in the first equation
A+6+A = 20
2A +6 = 20
Subtract 6 from each side
2A +6-6 = 20-6
2A =14
Divide by 2
2A/2 = 14/2
A = 7
Divide 22.2 by 4 since the perimeter is the outside and there are 4 edges
