Answer:
Step-by-step explanation:
Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.
f(x) = 40 - 2x
For x = 0,
f(x) = 40 miles
For f(x) = 0,
0 = 40 - 2x
x = 20 minutes
This shows that helicopter traveled 40 miles in 20 minutes.
Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.
For x = 0,
f(x) = 500 miles
For f(x) = 0,
x = 100 minutes
Commercial jet traveled 500 miles in 100 minutes.
Answer:
$21.94
Step-by-step explanation:
I'm not sure how many pizzas were ordered, but let's say you just got one large pizza that was $18.
First, the sales tax - 6%
$18 + 6% = $19.08
Then you give a 15% tip.
$19.08 + 15% = $21.94
Answer:
7.30
Step-by-step explanation:
T = 2π √(L/32)
3 = 2π √(L/32)
3/(2π) = √(L/32)
(3/(2π))² = L/32
L = 32 (3/(2π))²
L ≈ 7.30
