Ideal timeline of the dance routine = 4 minutes = 4 × 60 seconds = 240 seconds
Variation allowed in the dance routine timeline = +- 5 seconds
Let the timeline of the dance routine be T
⇒ 240 seconds - 5 seconds < T < 240 seconds + 5 seconds
⇒ 235 seconds < T < 245 seconds
⇒ 
minutes < T < 
minutes
⇒ 3.92 minutes < T < 4.08 minutes
So the least possible time of the dance routine can be 3.92 minutes (or 235 seconds) and the greatest possible time of the dance routine can be 4.08 minutes (or 245 seconds)
Answer:
hi! you can use desmos graphing calculator to help you graph these- just look it up and plug the equation in. its nice for future use as well.
Step-by-step explanation:
and no , (5,10) isn't a solution to the equation because it falls under x≥2 but not under y<x+3. Hope this helps !
The answer is 2.25 square inches or 7.065 square inches.
Answer:
the volume of the basketball when the radius is r
Step-by-step explanation:
V(r) is a function name V and argument list (r). Often the letter of the function name is a reminder of what the function computes. Here, V is chosen as the name because it computes Volume. The function uses r (for radius) as its independent variable. That is why r is listed in parentheses next to the function name.
So, V(r) represents a function that computes the volume of a sphere with radius r.
