Demoss graphing calculator
From what I think;
8.216secs - 1 wheel; 3.652- 1 hood
for I toy car with a wheel and hood the total time is 8.216+ 3.652 = 11.868secs
let x secs be the total time taken to put a wheel and hood for 42 cars
x secs = 42 cars × the total time for one car
x secs = 42× 11.868
x secs= 498.456 secs
Answer:
x
Step-by-step explanation:
Using the trigonometric identities
1 + tan²x = sec²x and 1 - sin²x = cos²x
secx = 
Given

= 
= 
= cos²x × cos²x
=
x
31 divided by 9548 is 0.00324675
