Really, you just need to find out how many ways 14 can be divided. It can be divided into 7 groups of 2, or 2 groups of 7.
Answer: 34.25
Step-by-step explanation:
If a function wouldn't represent area of a circle its domain would be all real numbers. For any number r we can calculate f(r)
But since radius of circle cannot be negative and it also doesnt make sense that it is 0 the answer would be all positive real numbers
Answer is a.
The critical points of <em>h(x,y)</em> occur wherever its partial derivatives and vanish simultaneously. We have
Substitute <em>y</em> in the second equation and solve for <em>x</em>, then for <em>y</em> :
This is to say there are two critical points,
To classify these critical points, we carry out the second partial derivative test. <em>h(x,y)</em> has Hessian
whose determinant is . Now,
• if the Hessian determinant is negative at a given critical point, then you have a saddle point
• if both the determinant and are positive at the point, then it's a local minimum
• if the determinant is positive and is negative, then it's a local maximum
• otherwise the test fails
We have
while
So, we end up with
Answer:
1. $12
2. 3 boxes
3. 2 boxes
Step-by-step explanation:
1. You first need to find the dollar amount each of them sold. To do this, you need to find the lowest common multiple for 4 and 6. The lowest common multiple is 12.
2. Kevin sells boxes of cookies for $4 each so, you need to find the value of X in this equation: 4 . X = 12. The value of X is 3.
3. Laura sells boxes of cookies for $6 each so we need to find the value of X in this equation: 6 . X = 12. X = 2 because that is the only answer that makes since.
