Answer:
Linear equations
Step-by-step explanation:
An easy and simple equation. F(t) = -15t +300
The formula for this is A= a + b/2 x h.
140 degrees because an angle of a circle is 360 degrees and you can subtract these angles from it to get 140 degrees
Vertical angles are congruent, so their measures are equal.
Set the angle measures equal and solve for x.
2x + 2 = 3x - 52
-x = -54
x = 54

The answer is inside a box.
<span>68=-16t2+64t+8
16t2-64t+60=0
4t2-16t+15=0
(2t-5)(2t-3)=0
t=5/2 or 3/2
The object is at 68 feet after 3/2 secs, and returns to 68 feet after another second..</span>
