A Strong wind blows to the west at a speed of 38.7 mph relative to the ground causing a commercial plane to change course. What should be the plane's velocity in order to maintain a southward direction at a constant speed of 452 mph relative to the ground?

Answers

Answer 1

The speed of the plane is the rate of change of distance over time

The speed of the plane should be 453.65 mph southwest

The speed of the wind is given as:

[tex]\mathbf{S_w = 38.7mph}[/tex]

The expected speed of the plane is:

[tex]\mathbf{S_s = 452mph}[/tex]

So, the actual speed is calculated using the following Pythagoras theorem

[tex]\mathbf{S_{sw}^2 = S_w^2 + S_s^2}[/tex]

This gives

[tex]\mathbf{S_{sw}^2 = 38.7^2 + 452^2}[/tex]

[tex]\mathbf{S_{sw}^2 = 205801.69}[/tex]

Take square roots of both sides

[tex]\mathbf{S_{sw} = 453.65}[/tex]

Hence, the speed of the plane should be 453.65 mph southwest

I need answer for this quick please

Answers

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 1, 4 ] , then

f(b) = f(4) = 4³ - 6(4)² - 4 = 64 - 96 - 4 = - 36

f(a) = f(- 1) = (- 1)³ - 6(- 1)² - (- 1) = - 1 - 6 + 1 = - 6 , then

average rate of change = [tex]\frac{-36-(-6)}{4-(-1)}[/tex] = [tex]\frac{-36+6}{4+1}[/tex] = [tex]\frac{-30}{5}[/tex] = - 6

Find the 52nd term of the arithmetic sequence -8 -12 -16

Answers

Answer:

a₅₂ = - 212

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 8 and d = a₂ - a₁ = - 12 - (- 8) = - 12 + 8 = - 4 , then

a₅₂ = - 8 + (51 × - 4) = - 8 - 204 = - 212

ASA Criterion for Congruence

ASA Criterion stands for Angle-Side-Angle Criterion. Under ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.

Here Angle Q and Angle S are 90  

and side QR = RS

and Angle QRP = Angle SRT (Vertically opposite angles)

23=r+11

r=23-11

r=12

Answer:

r=12

Step-by-step explanation:

We are given the equation 23=r+11. To solve for r, one side of the equation needs to be r, so we will isolate r by subtracting 11 on both sides:

23-11=r+11-11

12=r

Because the +11 and -11 cancel out, we are left with r on the right side of the equation and 12 on the left side. Therefore, the value of r is 12, or r=12.

Answers

Answer: x = 4

Step-by-step explanation:

To solve this problem, make use of the fact that you may add anything to an equation, as long as you do it to both sides.

Simply add 4x to both sides to get:

13 = 1 + 3x

Then simply add -1 to both sides to get:

12 = 3x

Then, divide both sides by 3 to get:

4 = x

She measure the length of the trees shadow ( on the ground) which was 42 meters. Then she positioned the ladder. Which was 2.4 meters high, and measured its shadow. The ladders shadow ( on the ground) was exactly 3 meters

Answers

Answer:

The tree was 33.6 meters tall.

Step-by-step explanation:

So the question is "How tall is the tree?" I take it.

tree height/shadow length = ladder height / shadow length

Notice that the heights are both in the numerator. A proportion should always do this. It should have the same units on either the two denominators or the 2 numerators.

x / 42 = 2.4 / 3                  Multiply both sides by 42

x = 42 * 2.4 / 3

x = 100.8 / 3

x = 33.6

Answer:

33.6

Step-by-step explanation:

x/42 = 2.4/3

x = 2.4/3 x 42

x = 2.4/1 x 14

x = 33.6/1

x = 33.6
