You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
Represents the line graphed
Answer:
45
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 3 - 2 = 1, thus
= 2 + (43 × 1) = 2 + 43 = 45
So... 1 foot = 30 cm
1 pound = 2 pounds
1 cup = 250 millilitres
I hope that helps!
