Answer:
The answer is C. -2
Step-by-step explanation:
The formula for slope is referred to "rise over run". So in this case you rise 2 over one (2/1) That gives you 2. But since the line is going down is -2
Answer:
R = 3.6
A = 2
Step-by-step explanation:
R is inversely proportional to A
....which means that....
; R = k/A.....(where k is a constant that does not change)....
;If R = 12 and A = 1.5....then k = 18..
obtain k,by substituting the values into the equation...k = RA
a) If A = 5....then R = 18/5....
; Ans..., R = 3.6
b) If R = 9....then A = 18/9
;Ans..., A = 2
First, we multiply 2.5 feet per second by the amount of seconds we are given.
2.5 * 5 = 12.5 feet
Now, let's subtract that number from 270 to find the height after 5 seconds.
270 - 12.5 = 257.5 feet above the ground.
After 5 seconds, the block is 257.5 feet above the ground.
Hope that helped!
