Answer:
Step-by-step explanation:
30t - 5t² = 10
5t² - 30t + 10 = 0
t = [30 ± √(30² - 4 ⋅ 5 ⋅ 10)] / [2 ⋅ 5]
= [30 ± √700] / 10
= [30 ± 10√7] / 10
= 3 ± √7
≈ 0.35 seconds and 5.65 seconds
The answer to the question is equal to 16
Answer:
2
Step-by-step explanation:
2/2+6=7
The median drawn from a vertex of a triangle intersects the opposing side at the mid point.
The three medians of a triangle intersect in a point named centroid, but that is another story.
B 7.50 reason total spent=4+.50(7)——-> 4+3.50———->$7.50
