Answer:
1.29 s
Step-by-step explanation:
h = -490t² + 1260t
810 = -490t² + 1260t
490t² - 1260t + 810 = 0
49t² - 126t + 81 = 0
(7t - 9)² = 0
7t - 9 = 0
t = 9/7
t ≈ 1.29
13/3?
I think it is but so you put 13/3 into a proper fraction so 4 1/3
Answer: wakanda fo eva
Step-by-step explanation:
Answer:
(x - 2)/3
(x - 4)/-5 or (-x + 4)/5
Step-by-step explanation:
this is an inverse function, and to solve an inverse function you would :
swap x and g(x) without bringing the x coefficient with it, just simply swap the variables. Then, solve for g(x), and that's it
the first question's answer is :
g(x) = 3x + 2
x = 3(g(x)) + 2
x - 2 = 3(g(x))
(x - 2)/3 = g(x)
the second one is:
g(x) = 4 - 5x
x = 4 - 5(g(x))
x - 4 = -5(g(x))
(x-4)/-5 = g(x)
Answer:
Yes. You are correct.
Step-by-step explanation:
Tan(U) = opposite / adjactent
Tan(U) = 7*√3 / 7
Tan(U) = √3
Just off the top of my head, they look right.
U = Tan-1 (√3)
U = 60
Therefore tan(W) = 90 - 60 = 30
