Answer:
no solution
Step-by-step explanation:
when you substitute for the equation is false
how I solved this:
1. substitute for
2. distribute the 3
3. combine like terms
this is incorrect because 12 does not equal -12, so there is no solution
Answer and Step-by-step explanation:
90ft = a
55ft = b
50ft = c
Plug into equation.
29.4° is the answer.
Answer:
a. 1.13 s
b. 30.25 ft
Step-by-step explanation:
Both questions can be answered by putting the equation into vertex form.
h = -16(t^2 -9/4t) +10 . . . . factor the leading coefficient from the t terms
Complete the square by adding the square of half the t coefficient inside parentheses and the opposite of the same amount outside parentheses.
h = -16(t^2 -9/4t +81/64) +10 +81/4
h = -16(t -1.125)^2 + 30.25
This tells us the vertex of the height curve is at (t, h) = (1.125, 30.25), which rounds to ...
- t = 1.13 seconds
- h = 30.25 feet
Answer:
No, lines ℓ and k are not parallell because their slopes are not equal
