Answer:
Step-by-step explanation:
We have
<span>Va(airplane)=150
East</span>
Vw(wind)=7.1
South East
<span>
</span><span>resulting vector R</span>
airplane
Vax=150 Vay=0 it only has component x
WindVwx=7.1*cos45=5.02
Vwy=7.1*sin45=-5.02
is negative because is South direction
|R|=(Rx^2+Ry^2) ^0.5
Rx=150+5.02=155.02
Ry=0-5.02=-5.02
<span>|R|=155.10
miles/hour South East</span>
Determine angle θ
Rx=R*cos(θ)
<span>Cos(θ)=Rx/R</span>
<span>Cos(θ)=155.02/155.10=0.9995</span>
θ =arc cos Rx/R
θ =1.8119 º
Rx represents the component in the East direction of the resultant force. Your contribution is given by both, the force of the plane and the wind. The contribution of the wind makes the airplane's speed greater
Ry represents the component in the South direction of the resulting force
Its contribution is exclusive of the wind since the airplane has no component
in this direction
|R| the force resulting from the combined action of the force of the plane and the force of the wind
θ represents the angle that forms the resultant force with respect to the x axis or east direction

Answer:
Here is the complete question:
For which pair of functions is the exponential consistently growing at a faster rate than the quadratic over the interval 0<=X<=5.
Answer is C (the third option)
Step-by-step explanation:
Basically in exponential growth a quantity may increase over time. When a quantity increases of decreases by equal or same percent over equal period of times this means that the quantity increases or decreases exponentially. I have attached the image of the correct option.
Answer:
27 vertical posts and 36 horizontal rails
Step-by-step explanation:
If Max builds 1style of fence with each section having 3vertical posts and 6horizontal rails, to calculate the number of posts and rails that he need for a fence that will be 9 sections long, we will use the following equality;
For Posts:
1section = 3 vertical posts
9 sections = x
Cross multiply
x × 1 = 9× 3
x = 27
Hence Max will need 27vertical posts for a fence that is 9sections long
For the rail:
1 section = 6 horizontal rails
6 sections = y
Cross multiply
y× 1 = 6 × 6
y = 36
Hence Max will need 36 horizontal rails for a fence that is 9sections long.
In total Max will need 27 vertical posts and 36 horizontal rails for a fence that is 9sections long
