I think it’s C but what grade is this
Answer:
= 2n + 3
Step-by-step explanation:
This is an arithmetic sequence with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 2 , then
= 5 + 2(n - 1) = 5 + 2n - 2 = 2n + 3
The length of the tangent from point D to point B can be calculated by adding the length of BC to the length of BD.
We are given that:
BC = 2 units
CD = 2 units
Therefore:
BD = BC + CD
BD = 2 + 2
BD = 4 units
(5,-1) and (2,-4) the solution is where the lines meet
Divide 45 by 5 and 5 hours by 5 so it’s 9 miles per hour. So the equation would be: m = 9/h (a fraction)
