Answer:
A 190-pound person would burn 285 calories at the same rate.
Step-by-step explanation:
<em>Calories burn depends on the weight</em>
<em>Weight of first person = 160</em>
Calories burn for 160 pounds in 30 mins = 237
Calories burn rate for 1 pound in 30 mins = = 1.5
<em>Calories burn for 190 Pound person would be:</em>
Weight of second person = 190
Calories burn for 190 pounds in 30 min:
As the burn rate of calories is same for the two persons:
= rate × weight
= 1.5 * 190
= 285 calories

The equation of a parabola that has intercepts of x=-2 and x=6 and passes through point (8,6) is f(x) = 3/10(x+2)(x-6)
<h3>Equation of a parabola</h3>
The standard equation of a parabola is in the form f(x) = (x-a)(x-b)
where a and b are the intercepts of the graph. Given the parabola that has intercepts of x=-2 and x=6, the resulting equation will be:
f(x) = a(x-(-2))(x-6)
f(x) = a(x+2)(x-6)
If the parabola passes through (8, 6), then;
6 = a(8+2)(8-6)
6 = a(20)
a = 6/20
a = 3/10
Substitute
f(x) = 3/10(x+2)(x-6)
Hence the equation of a parabola that has intercepts of x=-2 and x=6 and passes through point (8,6) is f(x) = 3/10(x+2)(x-6)

Step-by-step explanation:
Let x denote the time (in hours) that Yolanda spends doing cardiovascular work. Let y denote the time (in hours) that she spends on weight training.
1. Each week, she exercises for at least 10 hours. Thus,
2. She spends at most 6 hours doing cardiovascular work. So,
3. She spends at most 8 hours on weight training. Then,
Note that times x and y are always no less than 0, so
