Answer: 38
Step-by-step explanation:
14 - 2xy
(substitute x and y)
14 - 2 (-6) (2)
14 + 24
38
It's 4. Y=in(x)-5
Formula: Y= +/- a( x - h) + k
K= up/down
h= Right/left

Answer:
4.647 to the nearest thousandth.
Step-by-step explanation:
The formula for the length of an arc between x = a and x = b is
a
∫ √( 1 + (f'(x))^2) dx
b
Here f(x) = √x so
we have ∫ (√( 1 + (1/2 x^-1/2))^2 ) between x = 0 and x = 4.
= ∫ ( √( 1 + 1/(4x)) dx between x = 0 and x = 4.
This is not easy to integrate but some software I have gives me the following
length = √17 + 1/8 log(33 + 1/8 √17)
= 4.647.
t=0, d=0 so ans B is wrong
t=0, dd/dt <0 as it is propelled downward so ans C is wrong
ang vel = 2
/ period
= 2 / 4.5
= 4 / 9
so D is the correct answer
