Answer:
1
Step-by-step explanation:
(a+b)(a−b)=a²−b²
tan²(θ)+1=sec²(θ)
(sec(θ)+tan(θ))(sec(θ)−tan(θ))
=sec²(θ)−tan²(θ)
=(tan²(θ)+1)−tan²(θ)
=1
Answer:
t = ±12
Step-by-step explanation:
t^2=144
Take the square root of each side
sqrt(t^2)=± sqrt(144)
t = ±12
Answer:
11 sets of forks
Step-by-step explanation:
First subtract 406-278 to find total amount of forks needed which is 128 forks.
Then divide 128 by 12 to see how many sets of forks you need.
You get 10.67 but because you can't buy two thirds of a set, you have to round up to 11 sets of forks.
Hope this helps :)
