An airplane needs to head due north, but there is a wind blowing from the northeast at 50 km/hr. The plane flies at an airspeed
laiz [17]

Answer:\theta =2.415^{\circ}

Step-by-step explanation:

Using vector method to solve it

Resultant can be given by

R^2=700^2+40^2+2\times 700\times 40cos135

R^2=450,408

R=671.12 Km/hr

The angle made by resultant with 700 km/hr is \theta

using sine rule

\frac{40}{sin\theat }=\frac{R}{sin45}

sin\theta =0.0421509

\theta =2.415^{\circ}

3n+4 first the 7 terms
kiruha [24]

Answer:

4, 7, 10, 13, 16, 19, 22

Step-by-step explanation:

Not sure if there is more to this question but here is what I assume:

We want to find the first 7 terms of this equation given 3n+4

Assuming we are starting at 0 we plug 0 in for n.

3(0) + 4 → 4

So our first answer is 4

We continue by pugging in the next numbers after that to get to the first 7 terms

3(1) + 4 → 7

3(2) + 4 → 10

3(3) + 4 → 13

3(4) + 4 → 16

3(5) + 4 → 19

3(6) + 4 → 22
