Answer:
14 Bracelets
Step-by-step explanation:
1/10 is 6 minutes
1/4 is 15 minutes
6+15=21 minutes
60 minutes x5 is 300 minutes
300/21 = 14.3 but you cannot leave one in the middle so the answer is 14

<span>1. circle
2. parabola
3. ellipse
4. hyperbola
Let's look at each equation and see what they are:
1. x^2 + y^2 - 4x + 6y - 5 = 0
* There's a lot of crud in this equation, but the thing to note is that the x^2 and y^2 terms have the same scaling factor (which is 1). This should scream "circle" to you.
2. x^2 - 6y = 0
* Key thing to note here is that the y term isn't squared, but the x term is squared. This is a key sign that the equation is a parabola.
3. 4x^2 + 9y^2 = 1
* Here we have the sum of an x squared term and a y squared term. That kinda sounds like a circle, but there's those 2 coefficients scaling the results. And they're different. So we're looking for a closed curve that kinda looks like a circle, but it's stretched out a bit. And that's an ellipse.
4. 7x^2 - 9y^2 = 343
* Here we have a couple of squared terms for x and y. But we're not adding them together, we're subtracting. And that indicates a hyperbola.</span>
M can be any positive real number.
Explanation:
From f(x) = √(mx) ; if x is posive m has to be positive; if x is negative m has to be negative; if x is cero m can have any value, and the range will always be 0 or positve
From g(x) = m √x; x can only be 0 or positive and the range will have the sign of m.
Given we concluded that the range of f(x) can only be 0 or positive, then me can only be 0 or positive.
