Hi. Good?
15x + 25 = -20
15x = -20 - 25
15x = -45
x = -45/15
x = -3
Thanks, I hope I have helped.
Answer:
The solutions are t = 0 and t = 1. Since starting time is 0, the arrow is in the air for 1 second.
Step-by-step explanation:
Set the equation equal to zero.
−2t(8t − 8) = 0
Apply the Zero Product Property.
−2t = 0 or 8t − 8 = 0
Solve each equation for t.
t = 0 or 8t = 8
t = 1
Answer:
Sine is equal to opposite over hypotenuse in right triangles. Let's say we have a 3-4-5 right triangle, the side opposite the 90° angle is 5, and 5 is also the hypotenuse. 5/5 = 1
Therefore, in all right triangles, the side opposite the 90° angle is equal to the hypotenuse, and anything over itself is equal to one.
(Not sure if this is a mathematically correct way to explain it, but it makes the most sense to me.)
