1. We cannot pick both of the positive numbers 4 and 5 because the third one would be negative, and the overall product negative.
2. So we pick 5, the largest of (4, 5) and 2 negative numbers
3. Since the multiplication of the 2 negative numbers is positive, we pick the ones with larger absolute value, so -3 and -2
Answer: 5*(-3)*(-2)=5*6=30

Answer:
8√3 ≈ 13.86 ft
Step-by-step explanation:
The light source is usually placed at the focus, so the focus-vertex distance is p=3 ft. The equation for the parabola with its vertex at the origin is ...
y = 1/(4p)x^2
y = 1/12x^2
The opening for some y-value extends ±x from the axis of symmetry, so is a total of 2x in width.
For y=4, the corresponding value of x is ...
4 = 1/12x^2
48 = x^2
√48 = x = 4√3
Then the width of the searchlight opening is ...
2(4√3 ft) = 8√3 ft ≈ 13.86 ft
Answer:
We know the distance (d) equation in terms of rate (r) and time (t) as:
d=rt
Step-by-step explanation:
We have given d=336 km and t= 12 hours, so we have: 336 km = 12t <-- this is our equation.
Divide each side by 12 to solve for t:
12t/12=336/12
t= 28 km/ hour
Answer:
AB = 9
Step-by-step explanation:
Given that line, l is a perpendicular bisector of line segment AC. It intersects line segment AC at point B.
So, we can conclude that AB = BC ............ (1)
Also given that the length of line segment BC is 9.
Now, from equation (1) we can say that, AB = 9.
Therefore, the length of segment AB is 9. (Answer)
So first you would divide 1950/6 to find the amount for one year of their age.
Then you would multiply that by the ages, which should get you 4 numbers, then you all those numbers together. Try 9750.
