Answer:
We'd need to know the coordinates of the line segment.
3x + 2
since x + x + x is 3x.
Or you can be creative
(6x+4)/2
im just trying to hit the 20 chac minimum.
Im guessing the largest side of the triangle, i mean cmon. its the largest.
Answer:
Step-by-step explanation:
a) the equation representing the parabola is expressed as
h = -16t² - 4t + 20
c) to determine the height after 25 seconds, we would substitute 25 for t into the given equation. It becomes
h = -16(25)² - 4(25) + 20
h = - 10000 - 100 + 20
h = - 10080
d) when the coin lands on the ground, the height would be 0. Therefore,
-16t² - 4t + 20 = 0
Dividing both sides of the equation by 4, it becomes
- 4t² - t + 5 = 0
- 4t² - 5t + 4t + 5 = 0
- t(4t + 5) + 1(4t + 5) = 0
- t + 1 = 0 or 4t + 5 = 0
t = 1 or t = - 5/4
Since t cannot be negative, then t = 1 second
30 because 5x6= 30. All you have to do if the fractions are already simplified, is multiply the denominators together.
