Answer:
Step-by-step explanation:
when h(t)=0
-4.9 t²+19.6t=0
4.9t(-t+4)=0
either t=0 or t=4
so domain is 0≤t≤4
for range
h(t)=-4.9t²+19.6t
=-4.9(t²-4t+4-4)
=-4.9(t-2)²+19.6
so range is 0≤h≤19.6
The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12
Answer: <em>n </em>-<em> 4 = -15</em>
<em>n </em>= -11
Step-by-step explanation:
If -15 is the same as 4 less than <em>n, </em>that means that <em>n </em>- 4 = -15
Then you add 4 to each side of the equation to get <em>n </em>by itself. (-15 + 4 = -11)
That step leaves you with <em>n</em> = -11
