A plane travels 2,000 kilometers at a a speed of 900 kilometers per hour (kph) with no wind. When a tailwind is present, the pla

ne’s speed increases by x kilometers per hour. The time it takes the plane to travel the same distance with the tailwind, t(x), is defined by the function t(x)= 2,000/900+x. What is the meaning of the y-intercept for this function?

Answer:

The meaning of the y-intercept is the time needed for the plane to cover 2,000 kilometers at a a speed of 900 kilometers per hour (kph) with no wind.

Step-by-step explanation:

The time it takes the plane to travel 2,000 kilometers with the tailwind, t(x), is defined by the function

t(x)=\dfrac{2,000}{900}+x,

where x is the increase in speed when the plane travels with the wind (tailwind).

The y-intercept is at x = 0, then

t(0)=\dfrac{2,000}{900}+x\\ \\t(0)=\dfrac{20}{9}=2 \dfrac{2}{9}\ hours

The meaning of 2 \dfrac{2}{9} hours is the time needed for the plane to cover 2,000 kilometers at a a speed of 900 kilometers per hour (kph) with no wind.

Radda [10]

Answer:

a=567 km+900 km

a=1,467 km

b=567 km+169 km

b=736 km

x^2/a^2+y^2/b^2=1

x^2/(1,467)^2+y^2/(736)^2=1

Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, projvu u=(-8,8) , v= (
Jobisdone [24]

Answer:

none of the given options is true

Step-by-step explanation:

Given: u=(-8,8) , v= (-1,2)

To find: vectors w_1,w_2 such that u=w_1+w_2

Solution:

A vector is a quantity that has both magnitude and direction.

proj_vu=\frac{u\cdot v}{\left | v \right |^2}(v)\\=\frac{(-8,8)\cdot (-1,2)}{(\sqrt{ (-1)^2+2^2})^2}(-1,2)\\=\frac{8+16}{5}(-1,2)\\=\frac{1}{5}(-24,48)\\=(-4.8,9.6)

Let w_1=(-4.8,9.6)

So,

w_2=u-w_1\\=(-8,8)-(-4.8,9.6)\\=(-8+4.8,8-9.6)\\=(-3.2,-1.6)

So, u = (-4.8,9.6)+(-3.2,-1.6)

So, none of the given options is true
