Question: Explain how you would use the result of finding the ground speed to find the course of the airplane.

Answer: 181.2

Explanation:  vertical speed of 20.78 knots  

new course is (-148 , 20.78) = inverse tan ( 20.78 / -148) = 172° or 8° N of East at 149.45 knots

New speed (- 148)² + ( 20.28)² = 149.45 knots round and you get 181.2

The ground speed of the airplane is 181.18 knots (approx).

The formula of ground speed of a airplane is given below,

[tex]v_{g} =\sqrt{}[/tex][tex](v_{a} ^{2}+v_{w} ^{2}-2v_{a} v_{w}cos\alpha)[/tex]

where, [tex]v_{g}[/tex] = Ground speed of airplane

[tex]v_{a}[/tex] = Speed of the airplane relative to the air

[tex]v_{w}[/tex] = Wind speed

[tex]\alpha[/tex] =  Internal angle

Given, [tex]v_{a}[/tex] = 160 knots, [tex]v_{w}[/tex] = 24 knots

Here, the angles increase clockwise and east is 90° heading.

The airplane is flying a heading of 90° at 160 knots speed & wind is blowing from 240° at 24 knots speed.

So, the internal angle[tex](\alpha)[/tex] = 240°-90° = 150°

∴ Ground speed, [tex]v_{g} =\sqrt{}[/tex][tex](v_{a} ^{2}+v_{w} ^{2}-2v_{a} v_{w}cos\alpha)[/tex]

⇒ [tex]v_{g}[/tex] [tex]=\sqrt{}[/tex][tex](160^{2}+24^{2}-2*160*24*cos(150))[/tex]

⇒ [tex]v_{g}[/tex] = 181.18 knots (approx)

Hence the ground speed of airplane is 181,18 knots (approx).

Answer:

(B , D) = (-2,5)

Step-by-step explanation:

The given quadratic expression is

[tex]3x^{2} -x-10[/tex]

compare the given expression with [tex]ax^{2} +bx+c[/tex]

so we have [tex]a = 3 , b = -1 ,c = -10[/tex]

now [tex]ac=3 (-10)=- 30[/tex] and [tex]b= -1[/tex]

we need to find two numbers such that their product is -30 and sum is -1

-6 and 5 are such numbers

so we have

[tex]3x^{2} -6x+5x-10[/tex]

grouping first two terms and last two terms

[tex](3x^{2} -6x)+(5x-10)[/tex]

factor out 3x from first two terms and 5 from last two terms

[tex]3x(x-2) +5(x-2)[/tex]          

[tex](x-2)(3x+5)[/tex]        ( factor out (x-2))

[tex](x+(-2))(3x+5)[/tex]

hence B =-2 and D= 5

The speed that describes how fast the car was traveling when the driver applied the brakes is 49 mph.

What was the speed?

The formula that is often used by police officers to determine the speed from a skid mark is this s = √21d.

So, in this case, the length or distance of the skid mark is 115 feet. We can substitute this value in the formula to get;

Speed of car = √21(115)

Speed of car = √2,415

Speed of car = 49.1426 approximately 49 mph.

So, the speed that describes how fast the car was traveling when the driver applied the brakes is 49 mph.

Answer: 1%

Explanation:

Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000

There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.

Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%

Divide total full time employees by 20 to find how many groups of 20 there are, then multiply that number by 3 to find total part time employees:

250,000 / 20 = 12,500

12,500 x 3 = 37,500 part time employees.

Answer:

Jayda can cut 14 slices of dough that are 3/4 inches thick.  

Step-by-step explanation:

In order to solve this problem, we need to take the total amount of dough at 10 1/2 inches and divide it by the thickness of one slide, 3/4 inches, to find the number of slices that can be made from the total amount.  You can solve this two different ways.  You can either convert your fractions to decimals so that 10 1/2 becomes 10.5 and 3/4 become 0.75 and then divide 10.5/0.75 to get 14.  However, you can also keep them as fractions converting 10 1/2 to 21/2 and dividing by 3/4.  When we divide with fractions with keep-change-flip, or keep the first fraction-change the sign to multiplication-flip the second fraction.  So, we multiply 21/2 x 4/3 and get 84/6, or 14.

Answer:

Divide 5.4 by 0.5

Step-by-step explanation:

It's says to find the number of laps she swam. It doesn't ask us to figure out how many laps she could have run with the amount of laps she did.

To find the number of laps Flo swam, divide the total distance Flo swam (5.4 km) by the length of one lap in the pool (0.05 km). This results in 108 laps.

To find out the number of laps Flo swam, we must take the total distance she swam and divide it by the length of one lap in the pool. According to the chart, the length of one lap in a standard-sized pool is 0.05 kilometers. Therefore, the best method would be to divide 5.4 (the total distance Flo swam in kilometers) by 0.05 (the length of one lap in kilometers).

So, we take 5.4/0.05 = 108. This means that Flo swam 108 laps in the pool. Remember, when you want to find how many times a certain distance fits into another, you should utilize division.

In the figure below :

d = 2.08, e = 5, c = 5.42 , a = 22.78°, b = 67.22°

Step-by-step explanation:

Side lengths :

[tex]2\cdot e=10\\ \Rightarrow e=5 feet\\\frac{d}{e}=\frac{5}{12}\\\Rightarrow d=\frac{25}{12}\approx 2.08 feet[/tex]

By pythagoras theorem,

[tex]c^2=d^2+e^2\\c^2=29.33\\c\approx 5.42 feet[/tex]

Now to find angles,

[tex]a+b+90^{\circ}=180^{\circ}\\\Rightarrow a+b=90^{\circ}\\\tan a=\frac{d}{e}\\\Rightarrow \tan a =0.42\\\Rightarrow a=22.78^{\circ}\\\Rightarrow b=67.22^{\circ}[/tex]

The unknown side lengths of the shed's roof are:

Angle measure at the top of the roof: 22.62 degrees

Vertical length of the roof (rise): 4.17 feet

Horizontal length of the roof (run): 5 feet

To determine the unknown angle measures and side lengths of the shed's roof, we can use the given information about the roof pitch and span.

Angle Measures

The roof pitch is 5:12, which means that for every 12 horizontal inches, the roof rises 5 inches. This corresponds to an angle of approximately 22.62 degrees.

Side Lengths

The span of the roof is 10 feet, which represents the horizontal distance from one side of the shed to the other.

Since the roof pitch is 5:12, we can calculate the rise of the roof by dividing the span by 12 and multiplying by 5:

Rise = (10 feet * 12 inches/foot) * (5/12) = 41.667 inches ≈ 4.17 feet

Therefore, the unknown side lengths of the shed's roof are:

Angle measure at the top of the roof: 22.62 degrees

Vertical length of the roof (rise): 4.17 feet

Horizontal length of the roof (run): 5 feet

c. between 0&1 and 2&3

Step-by-step explanation:

The roots of the given quadratic functions lie between 0&1 and 2&3 thus option (C) is correct.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

As per the given quadratic equation,

f(x) = 2x² - 5x + 1

The value of x will be as,

x = [-(-5) ± √((-5)² - 4 ×2 × 1)]/(2 × 2)

x = (5 ± √17)/4

x = 0.219 and x = 2.28

Answer:

c=8

Step-by-step explanation:

3c/8 = (c+4)/4

We can use cross products to solve

3c          c+4

-----  =   ----------

8             4

 3c*4 = 8 *(c+4)

12c = 8c+32

Subtract 8c from each side

12c-8c = 32

4c = 32

Divide by 4

4c/4 = 32/4

c =8

The solution to the equation 3c/8 = c+4/4 is found by first simplifying the equation to 3c = 4c + 16, then isolating 'c' gives -c = 16, and finally multiplying both sides by '-1' gives the solution, c = -16.

To solve the equation 3c/8 = c+4/4, firstly we'll simplify it, eliminating fractions by multiplication. The equation becomes 3c = 4c + 16.

Next, we rearrange the equation to isolate 'c', by subtracting '4c' from both sides which results in -c = 16.

Finally, to get the value of 'c', we multiply both sides by '-1'. Hence, the solution to the equation is c = -16.
