Answer:

Flight arrived in london on 5 : 35 pm Wednesday

Step-by-step explanation:

Time = 16 h 35 min

Time difference = 7 h

Flight time  =  8am

So

     According to perth time flight reached in london is

         8 am + 16 h 35 m =  8 am + ( 12 h + 4h + 35 m) =

         8pm + 4h +35 =  12am + 35m   = 12 : 35 am

The time difference is 7 h ,so minus this from  perth time

      12 : 35 am -  7h  =   5 : 35 pm

Answer:

[tex]x=750m[/tex]

Step-by-step explanation:

[tex]Assuming[/tex] [tex]That[/tex]:

[tex]1m=3.3ft[/tex]

We can make the conversion from feet per second to meters per second with this procedure:

[tex](165 \frac{ft}{s} ) (\frac{1m}{3.3ft} )=50\frac{m}{s}[/tex]

Let [tex]x[/tex] be the amount of meters the parachutist will fall during 15 seconds of free fall

Having that in 1 second the parachutist falls 50 meters, we can calculate [tex]x[/tex] :

[tex]x=(50\frac{m}{s} )(15s)[/tex]

[tex]x = 750 m[/tex]

Answer:

32°

Step-by-step explanation:

Let the angle next to 121° be a,

a+121°=180°

a=180-121=59°

Now we have a=59°,

89° (given) and x, these threes form a triangle, therefore,

x+a+89°=180°

×+59°+89°=180°

x+148°=180°

x=180°-148°

x=32°

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

Answer:

here's your answer hope it helps you

Step-by-step explanation:

the upper bound of an interval uses the number of samples to get its value. same is said for the population standard deviation.

Answer:

a = 156°

b = 132°

c = 108°

Step-by-step explanation:

The sum of the exterior angles of a polygon equals 360°. The sum of an interior and exterior angle equals 180°. There are two missing exterior angles that you need to find the measure of so we can find the value of x.

First exterior angle is with the 82° interior angle. Subtract from 180 to find the exterior angle.

180 - 82 = 98°

The second exterior angle is with the 134° interior angle. Subtract from 180 to find the exterior angle.

180 - 134 = 46°

Now add all the exterior angles together and set them equal to 360.

x + 2x + 3x +72 + 98 + 46 = 360

6x + 216 = 360

6x + 216 -216 = 360 -216

6x = 144

6x/6 = 144/6

x = 24

No find the exterior angles then subtract each one from 180°.

To find a.

a + x = 180

a + 24 = 180

a + 24 - 24 = 180 - 24

a = 156°

To find b.

b + 2x = 180

b + 2(24) = 180

b + 48 = 180

b + 48 - 48 = 180 - 48

b = 132°

To find c.

c + 3x = 180

c + 3(24) = 180

c + 72 = 180

c + 72 - 72 = 180 -72

c = 108°

The main idea is to exploit the trigonometric identity,

sin²(θ) + cos²(θ) = 1

2. For an integral containing 16 - 81x², you might substitute x = 4/9 sin(θ) (with differential dx = 4/9 cos(θ) dθ, but without an actual integral to work with this isn't really important). Then

16 - 81x² = 16 - 81 (4/9 sin(θ))²

… = 16 - 81 (16/81 sin²(θ))

… = 16 - 16 sin²(θ)

… = 16 (1 - sin²(θ))

… = 16 cos²(θ)

so that in the root expression, we would end up with

[tex]\left(16 - 81x^2\right)^{7/2} = \left(16\cos^2(\theta)\right)^{7/2} = 2^{14} |\cos(\theta)|^7[/tex]

since [tex](ab)^c=a^cb^c[/tex] for all real a, b, and c; [tex]16^{7/2}=\left(2^4\right)^{7/2}=2^{14}[/tex]; and [tex]\sqrt{x^2}=|x|[/tex] for all real x.

The goal is to replace x with some multiple of sin(θ) that makes the coefficients factor out like they did here, which then lets you reduce 1 - sin²(θ) to cos²(θ).

And don't be discouraged by the absolute values; in the context of a definite integral, there are things that can be done to remove them or otherwise simplify absolute value expressions.

3. Substitute z = 1/√8 sin(θ) (so that dz = 1/√8 cos(θ) dθ). Then

1 - 8z² = 1 - 8 (1/√8 sin(θ))²

… = 1 - 8 (1/8 sin²(θ))

… = 1 - sin²(θ)

… = cos²(θ)

so that

[tex]\left(1-8z^2\right)^{3/2} = \left(\cos^2(\theta)\right)^{3/2} = |\cos(\theta)|^3[/tex]

Therefore option C is correct.

The Volume of the cone is 21π cubic units

The formula for calculating the volume of a cone is expressed as:

V = 1/3πr²h

where:

r is the radius = 3 units

h is the height = 7units

The volume of the cone = 1/3π(3)²*7
Volume of the cone = 3π * 7

Volume of the cone = 21π cubic units

Hence the Volume of the cone is 21π cubic units

Step-by-step explanation:

[tex]f'(x)=6x^{2}-6x-12[/tex]

So f'(x)=0:

x^2 - x - 2 = 0

(x-2)(x+1)=0

x=-1, 2

So we need to find the value of f at those critical points and also at the endpoints of the interval

f(-1)=-2-3+12+1=8

f(2)=16-12-24+1=-19

f(-2)=-16-12+24+1=-3

f(3)=54-27-36+1=-8

so the max is 8 and the min is -19

Answer:

Therefore has one solution.

explanation:

Given equations:

6x + y = -7

-24x -7y = 25

Make y the subject:

6x + y = -7

y = -7 - 6x ..............equation 1

-24x -7y = 25

-7y = 25 + 24x

y = (25 + 24x)/-7 ..........equation 2

Solve them simultaneously:

(25 + 24x)/-7 = -7 - 6x

25 + 24x = -7 (-7 - 6x)

25 + 24x = 49 + 42x

42x - 24x = 25- 42

18x = -24

x = [tex]-\frac{4}{3}[/tex]

Then y is:

y = -7 - 6x

y = -7 - 6( [tex]-\frac{4}{3}[/tex])

y = 1

Has one separate value of x and y: (  [tex]-\frac{4}{3}[/tex] , 1 ); so it has one solution.

Answer:

180m

Step-by-step explanation:

The figure shown in the picture is a right triangle.

We have two of it's sides and need to find the hypotenuse (the side in front of the right angle).

To find that we must use the Pythagorean theorem:

[tex]c^{2} = {a}^{2} + {b}^{2} [/tex]

Side a is 400m and side b is 300m.

Therefore:

[tex]c^{2} = {300}^{2} + {400}^{2} [/tex]

[tex]c = \sqrt{300 \times 300 + 400 \times 400} = 500[/tex]

Now that we know that side c is 500m we must just substract the distance between Marla and the dock with the lenght of the side to find the answer

500 - 320 = 180m
