Which explanation justifies how the area of a sector of a circle is derived?

Mathematics

The sector of a circle is drawn by drawing two radii intercepting an arc. The area of the sector is calculated by calculating first the area of the whole circle. Then, this value is multiplied by the ratio the measure of the intercepted arc to one whole revolution. The answer to this item is the THIRD OPTION.

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7) ?
vitfil [10]
Assume that f(5)=8. So, (5, 8) is a point in the graph of f.

For g(x) to give us 8, we need x to be 12, because in that case we would have:

      g(12)=f(12-7)=f(5), which is 8. Thus, (12, 8) is a point on the graph of g.


Comparing (5, 8) in f, and (12, 8) in g, we can see that the graph of g is the graph of f shifted 7 units to the right.


Answer: <span>C) The graph of g(x) is the graph of ​f(x)​ translated 7 units right.</span>

I need help with question 3
agasfer [191]

Answer:

see explanation

Step-by-step explanation:

To find the y-intercept let x = 0, in the equation

6x - 3y = 15 → (1)

x = 0 : - 3y = 15 ⇒ y = - 5 ⇒ (0, - 5) ← y- intercept

x + 3y = - 8 → (2)

x = 0 : 3y = - 8 ⇒ y = -\frac{8}{3} ⇒ (0, - \frac{8}{3}) ← y- intercept

As soon as I knew cars purchased and driven away from the dealership it begins to lose its value or depreciate also bought a 199
balandron [24]

Answer:

  11.1%

Step-by-step explanation:

The percentage change in a value can be computed from ...

  %change = ((new value)/(old value) -1) × 100%

  = ((8500/9559) -1) × 100%

  = (0.8892 -1) × 100%

  = -11.08%

The value of the car decreased about 11.1% in the first year.

Does anyone know how to solve this?
Bezzdna [24]

Use this version of the Law of Cosines to find side b:

b^2 = a^2 + c^2 − 2ac cos(B)

We want side b.

b^2 = (41)^2 + (20)^2 - 2(41)(20)cos(36°)

After finding b, you can use the Law of Sines to find angles A and C or use other forms of the Law of Cosines to find angles A and C.

Try it....
