Answer:Speed of airplane= 43.18mi/he

Direction of the airplane relative to the ground=4.64°. Counter-clockwise rotation from west.

Step-by-step explanation: welovity/speed is represented as magnitudes of vectors.

Let A= the vector of the airplane

Let W= the vector of the wind

From the diagram,total vector F= A + w

F= 320+ 40cos45°I +0j) + (0i + 40sin46°)

F=320+28.28i+28.28j

To calculate the magnitude

/F/=root of A2 +w2

/F/=root320+40cos45°2+40sin45°2

/F/=root 1919.5168

/F/=43.18= speed

To calculate the direction of the airplane relative to the ground, use tan function because it is a right triangle as seen in the diagram

Tan x= opp/adj=40sin45/320+40cos45

Tanx=28.28/348.28

Tanx=0.091199

×=tan-1 0.091199

×=4.64

Part A

This is an arithmetic sequence with starting term a(1) = 17 and common difference d = -7.

a(n) = a(1) + d(n-1)

a(n) = 17 + (-7)(n-1)

a(n) = 17-7(n-1)

a(n) = 17-7n+7

========================================================

Part B

We have a geometric sequence here because we multiply by the same quantity (5) each time. This makes the common ratio be r = 5.

The starting term is t1 = 3

The nth term of this geometric sequence can be expressed as...

t(n) = t1*(r)^(n-1)

Answer:

  34 nickels

Step-by-step explanation:

First, consider the value if they were all dimes. That would be 61×$0.10 = $6.10. Next, realize this is more than the actual amount by 1.70. Of course, replacing one of the 61 dimes by a nickel reduces the total amount by $.05, so we must have ...

  $1.70/$0.05 = 34

nickels in the mix.

Abby has 34 nickels.

_____

Alternate solution methods

I like to solve these using number sense, as above. Equivalently, an equation can be written using n to represent the number of nickels. The total value is then ...

  .05n + .10(61 -n) = 4.40

  -.05n +6.10 = 4.40 . . . . . . eliminate parentheses

  -.05n = -1.70 . . . . . . . . . . . subtract 6.10

  n = -1.70/-.05 = 34

Hopefully, you notice some similarities between this solution and the one in words, above.

__

Often, you will see this sort of problem formulated using two equations.

  n + d = 61 . . . . . . . . . . number of coins (d=#of dimes)

  .05n +.10d = 4.40 . . . .value of coins

If we solve this by substitution, we can use d=61-n, and get ...

  .05n +.10(61-n) = 4.40 . . . . . . looks like our equation in the previous section

By creating two equations for the total value of coins and the total number of coins Abby has, we can solve for both the number of dimes and nickels she holds. After doing the required calculations, we find that Abby has 34 nickels.

The subject of this question is algebra and it involves solving a system of equations. This is a classic problem that can be solved using two equations because we have two unknowns: the number of dimes and the number of nickels.

So, Abby has 34 nickels.

Answer: his speed when skateboarding is 6 mph and when walking is 3 mph

Step-by-step explanation:

Let x represent Marlon's walking speed.

Marlins speed on his skateboard is 2 times his walking speed. This means that his skating speed would be 2x.

At 1:30 Marlon left his house to go to the beach a distance of 6.75 mi. He rode his skateboard until 2:15. This means that the total time he spent skating is 45 minutes = 45/60 = 0.75 hours

Distance = speed × time

Distance covered while skating would be

2x × 0.75 = 1.5x

He walked the rest of the way. He arrived at the beach at 3:00. This means that the time that he spent walking is 45 minutes = 0.75 hours.

Distance covered while walking would be

x × 0.75 = 0.75x

Total distance covered is 6.75 miles. Therefore

1.5x + 0.75x = 6.75

2.25x = 6.75

x = 6.75/2.25

x = 3 miles per hour

His skating speed = 2 × 3 = 6 miles per hour.

Answer:

Therefore the angle that the line through the given pair of points makes with the positive direction of the x-axis is 45°.

Step-by-step explanation:

Given:

Let

A(x₁ , y₁) = (1 , 4) and  

B( x₂ , y₂ ) = (-1 , 2)

To Find:

θ = ?

Solution:

Slope of a line when two points are given is given bt

[tex]Slope(AB)=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Substituting the values we get

[tex]Slope(AB)=\dfrac{2-4}{-1-1}=\dfrac{-2}{-2}=1\\\\Slope=1[/tex]

Also Slope of line when angle ' θ  ' is given as

The insurance costs £602.02 now.

Step-by-step explanation:

Amount paid for car insurance = £635.71

Price reduce = 5.3%

Amount of reduce = 5.3% of amount paid

Amount of reduce = [tex]\frac{5.3}{100}*635.71[/tex]

Amount of reduce = [tex]0.053*635.71[/tex]

Amount of reduce =  £33.69263

Rounding off to two decimal place

Amount of reduce =  £33.69

Reduced price = Amount paid - Amount of reduce

Reduced price = 635.71 - 33.69 =  £602.02

The insurance costs £602.02 now.

Original price × (1 - reduction percentage) = Reduced price. £635.71 × (1 - 0.053) ≈ £602.97 (rounded to 2 DP).

let's break it down step by step:

1. Calculate the reduction amount:

  Multiply the original price (£635.71) by the reduction percentage (5.3% or 0.053).

  Reduction Amount = £635.71 * 0.053

2. Subtract the reduction amount from the original price:

  Subtract the reduction amount from the original price to find the reduced price.

  Reduced Price = £635.71 - Reduction Amount

Now, let's plug in the values:

1. Calculate the reduction amount:

  Reduction Amount = £635.71 * 0.053

                   ≈ £33.73763

2. Subtract the reduction amount from the original price:

  Reduced Price = £635.71 - £33.73763

                ≈ £602.97237

Rounded to two decimal places:

Reduced Price ≈ £602.97

So, after the 5.3% reduction, Terry's car insurance costs approximately £602.97.

The option [tex]\frac{(x+5)(x+2)}{x^3-9x}[/tex] is correct

The difference of the given expression is

[tex]\frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})=\frac{(x+5)(x+2)}{x^3-9x}[/tex]

Step-by-step explanation:

Given expression is [tex]\frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})[/tex]

To find the difference of the given expression as below :

[tex]\frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})[/tex]

[tex]=\frac{2x+5}{x(x-3)}-(\frac{3x+5}{x(x^2-9)})-({\frac{x+1}{x^2-9})[/tex]

[tex]=\frac{2x+5}{x(x-3)}-(\frac{3x+5}{x(x^2-3^2)})-({\frac{x+1}{x^2-3^2})[/tex]

[tex]=\frac{2x+5}{x(x-3)}-(\frac{3x+5}{x(x-3)(x+3)})-({\frac{x+1}{(x-3)(x+3)})[/tex]  

( using the formula [tex]a^2-b^2=(a+b)(a-b)[/tex] )

[tex]=\frac{2x+5(x+3)-(3x+5)-x(x+1)}{x(x-3)(x+3)}[/tex]

[tex]=\frac{x^2+7x+10}{x(x^2-9)}[/tex] ( by factoring the quadratic polynomial )

[tex]=\frac{(x+5)(x+2)}{x^3-9x}[/tex]

Therefore [tex]\frac{2x+5}{x^2-3x}-(\frac{3x+5}{x^3-9x})-({\frac{x+1}{x^2-9})=\frac{(x+5)(x+2)}{x^3-9x}[/tex]

Therefore the difference of the given expression is

[tex]\frac{(x+5)(x+2)}{x^3-9x}[/tex]

Therefore option [tex]\frac{(x+5)(x+2)}{x^3-9x}[/tex] is correct

Answer:

x = 1.64 in   the size of the side of the square

Step-by-step explanation:

Let call x side of the square to be cut from cornes, then:

First side of rectangular base

L = 14 - 2*x

And the other side

d = 8 -2*x

Then Volume of the box

V(b) = L*d*x

V(x) =  ( 14- 2*x ) * ( 8 -2*x)*x

V(x) = ( 112 -  28*x  -16*x + 4*x² )*x    ⇒  4*x³ - 44*x² + 112*x

Taking derivatives on both sides of the equation we get:

V´(x) = 12*x² - 88*x +112

V´(x) = 0       ⇒     12*x² - 88*x +112 = 0

A second degree equation, solvin it

3x² - 22*x +  28 = 0

x₁,₂ = [ 22 ± √484 - 336   ] / 6

x₁   =  (22 + 12,17) /6         x₂  =  ( 22 - 12.17 ) / 6

x₁   =  5.69     We dismiss this solution since it make side 8 - 2x  a negative length

 x₂  =  9.83/6      

x₂  =  1.64

Then x = x₂  = 1.64 in

The equation representing the problem is [tex]x=\frac{24\times 6}{32}[/tex].

Mr. Patel used 5 bags of seeds.

Step-by-step explanation:

Given:

Number of times bird feeder refilled =24

Number of cups of seeds used each time = 6 cups

Number of seeds each bag holds = 32 cups.

We need to write the equation to represent the problem.

Solution.

Let the total number of bag of seed be 'x'.

First we will find the Total number of cups of seeds used.

Now we can say that;

Total number of cups of seeds used can be calculated by multiplying Number of times bird feeder refilled by Number of cups of seeds used each time.

framing in equation form we get;

Total number of cups of seeds used = [tex]24\times6 \ cups[/tex]

Now We know that;

1 bag holds = 32 cups

Total number of bags required = [tex]24\times6 \ cups[/tex]

So we can say that;

Total number of bags required is equal to Total number of cups of seeds used divided by number of seed hold by each bag.

framing in equation form we get;

[tex]x=\frac{24\times 6}{32}[/tex]

Hence the equation representing the problem is [tex]x=\frac{24\times 6}{32}[/tex].

On solving we get;

[tex]x=4.5[/tex]

Since bags cannot be bought in half or in decimal value.

Hence we can say Mr. Patel used 5 bags of seeds.

Answer:

The initial temperature of the soda is 16°C

The temperature of the soda after 18 minutes is -12°C

Step-by-step explanation:

T(x) = -12+28e^-0.38x

When x = 0

T(0) = -12+28e^-0.38(0) = -12+28e^0 = -12+28(1) = -12+28 = 16°C

Initial temperature of the soda is 16°C

When x = 18

T(18) = -12+28e^-0.38(18) = -12+28e^-6.84 = -12+28(0.0011) = -12+0.0308 = -11.9692°C = -12°C (to the nearest degree)

The temperature of the soda after 18 minutes is -12°C

  y = 2sin((π/7)x)

Step-by-step explanation:

The graph goes through (0, 0) and has a range of ±2. This matches a sine function with an amplitude (A) of 2 and a vertical offset (C) of zero.

The half-period is 7, so the value of k is such that 7k = π, or k = π/7.

The desired function is y = 2·sin((π/7)x).

Answer:

1. Ernest has $82.5 and Gene has $117.5

2. c) 125x + 1500 = $20000

Step-by-step explanation:

If we mark Gene's half dollars with x, then it is given that Ernest has 8 more, which is x+8.

It is also given that Ernest has no quarters, but Gene has them as many as Ernest has half dollars, which is x+8.

And it is given that they both have 45 dimes each, which is $4.5 each.

Now, let's add up all these numbers:

Ernest: (x+8)•0.5 + 0•0.25 + 4.5 = 0.5x + 8.5

Gene: x•0.5 + (x+8)•0.25 + 4.5 = 0.75x + 6.5

They collected $200 together which means:

0.5x + 8.5 + 0.75x + 6.5 = $200

1.25x + 15 = $200

If we want to avoid decimal number, we can multiply whole equation with 100:

125x + 1500 = $20000

so, the correct answer is C.

Finally, to find x:

125x = 18500

x = 148

Ernest had 0.5x + 8.5 which is $82.5

Gene had 0.75x + 6.5 which is $117.5

Answer:

100 students play only basketball.            

Step-by-step explanation:

We are given the following information in the question:

Total number of students in school = 240

Number of students that play soccer =

[tex]\dfrac{1}{3}\times \text{Total number of students}\\\\=\dfrac{1}{3}\times 240 = 80[/tex]

n(S) =80

[tex]n(S\cap B) = 44[/tex]

[tex]n(S'\cap B') = 60[/tex]

Formula:

[tex]n(S\cup B) = \text{Total} - n(S' \cap B')\\n(S\cup B) = n(S) + n(B) - n(S\cap B)[/tex]

Putting the values, we get,

[tex]n(S\cup B) =240-60=180\\n(S\cup B) = 180 = 80 - 44 + n(B)\\n(B) = 180 - 80 + 44= 144[/tex]

Thus, 144 students play  basketball.

Out of these 144, 44 plays soccer as well.

[tex]\text{Student only playing basketball} = 144 -44 = 100[/tex]

Thus, 100 students play only basketball and not soccer.
