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

Explanation:

The degree of separation from the two cities is 30-7 = 23 degrees.

Let's say the point C is at the center of the earth. This would mean angle BCA is 23 degrees.

Any longitude line helps form what is known as a great circle or orthodrome. This is a math term that describes a circle that is centered at the same location as the sphere's center. Imagine that you can wrap a string around the earth and this string only follows this particular longitude line. This string is effectively a vertical equator in a way. The question is: what is the length of this string?

Well that would be the circumference of the circle with radius 3960 miles because the longitudinal circle has the same radius as the sphere.

That approximates to...

C = 2*pi*r

C = 2*pi*3960

C = 24,881.4138164311

C = 24,881.41

So a bit less than 25 thousand miles. I used the calculator's stored version of pi rather than something like 3.14 to get the best accuracy possible. This is the full string's length if we want to travel the entire distance around the globe but stay entirely on this particular longitude line

We don't want the full string's length. Instead, we want just a fractional portion of it. Specifically, we want 23/360 of it because of the central angle of 23 degrees. This will give us the distance between the two cities.

So (23/360)*24,881.4138164311 = 1,589.64588271642

This then rounds to 1589.65 when rounding to the nearest hundredth.

The distance between the two cities is approximately 1589.65 miles

This is comparable to the driving distance from Los Angeles, CA to Houston, TX (approximately 1547 miles).

2)8-y

Answer:

MN = 11

Step-by-step explanation:

M___A___Z___N

MZ =MA+AZ

MZ = 5x + 3x -2 = 8x - 2

MZ = AN

8x - 2 = 6(2x-1)

8x - 2 = 12x - 6

12x - 8x = 6 -2

4x = 4

x =4/4

x =1

MA= 5x = 5(1) = 5

AZ = 3x-2 = 3(1) - 2 = 3 -2= 1

MZ = 8x -2 = 8(1)-2= 8-2=6

AN = 12x - 6 = 12(1)-6 = 12 - 6 = 6

MN = MA + AN = 5 + 6 = 11

Answer:

y = -26

Step-by-step explanation:

[y = 2 - 2x] + [y = -16 + 2(x - 3)^2​]

y = -16 + 2x - 6^2

y = -16 + 2x - 6^2 + 2 - 2x

y = (+2x - 2x) - 16 - 6^2 + 2

y = -16 - 6^2 + 2

y = -16 - 12 + 2

y = - 28 + 2

y = -26

Answer:

after 6 years

Step-by-step explanation:

thats when the lines intersect, (6,300)

There will be equal enrollment in Spanish and French classes after 6 years from now.

The red line shows the number of students enrolled in French class each year from now and blue line shows the number of students enrolled in Spanish class each year from now.

The point of intersection of the lines is the point which lies in both the line.

So, it represents the point or time when there are same number of students enrolled in both French and Spanish classes.

From the graph, we can see that the two lines at a point [tex](6,300)[/tex]. The value on the [tex]x[/tex]-coordinate shows the years from now. So, we can say that there will be equal number of students enrolled in two classes after 6 years.

Answer:

Loss Amount: 175; Price: 3325

Step-by-step explanation:

You can multiply 3500 by 0.05 (which is 5% in decimal) to find how much is the loss. Then, you subtract the loss from the base price to find the new price.

Answer:

Loss =175, sold = 3325

Step-by-step explanation:

He bough at 3500

So 100 percent is 3500

And they said he had a 5% loss

So in other words, he sold it to Alex at 95% of the price he bought

So

3500 x 95%

3500 x 95/100

=3325

This is the price when Hitler sold it to alex

Now how much did Hitler lose?

3500 - 3325

=175

Answer: 8x = $39.62 - $6.74

Step-by-step explanation:

Cost of 1 bag of lemons = $x

Cost of 8 bags of lemons = 8*x = 8x

Cost of 8 bags of lemons = Total cost - cost of the egg

8x = $39.62 - $6.74

Step-by-step explanation:

Q1 . (f+g)(x) = f(x) + g(x)

=4x-4 +2x^2 -3x

= 2x^2 + x -4

Q2. (f-g)(x) = f(x) - g(x)

= 2x^2−2 - (4x+1)

= 2x^2 -2 -4x -1

= 2x^2 - 4x -3

Q3. h(x)=3x−3 and g(x)=x^2+3

(h.g)(x) = h(x) × g(x)

= (3x-3) × (x^2 + 3)

=3x^3 -3x^2 + 9x -9

Q4.f(x)=x+4 and g(x)=x+6

(f/g)(x) = f(x) ÷ g(x)

= x+4 / x+6

the domain restriction is x>-6

x<-6

x doesn't equal (-6)

If the two function f(x) and g(x) are to be combined, use basic arithmetic rules,

(f + g)(x) = f(x) + g(x)

(f - g)(x) = f(x) - g(x)

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

(f . g)(x) = f(x) × g(x)

Question 1

f(x) = 4x - 4 and g(x) = 2x² - 3x

[tex](f+g)(x)=f(x)+g(x)[/tex]

Therefore, [tex](f+g)(x)=(4x-4)+(2x^2-3x)[/tex]

                                   [tex]=2x^2+x-4[/tex]

Question 2

f(x) = 2x² - 2 and g(x) = 4x + 1

Since, (f - g)(x) = f(x) - g(x)

Therefore, (f - g)(x) = (2x² - 2) - (4x + 1)

                               = 2x² - 2 - 4x - 1

                               = 2x² - 4x - 3

Question 3

h(x) = 3x - 3 and g(x) = x² + 3

Since, (h - g)(x) = h(x) - g(x)

Therefore, (h - g)(x) = (3x - 3) - (x² + 3)

                                = 3x - 3 - x² - 3

                                = -x² + 3x - 6

Question 4

F(x) = x + 4 and g(x) = x + 6

Since, [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

Therefore, [tex](\frac{f}{g})(x)=\frac{x+4}{x+6}[/tex]
