Answer:

Step-by-step explanation:

The rule is that an arc has the same degree measure as does the central angle that cuts it off. Arc CE is cut off by angle made by C-the center of the circle-E. That angle measures 85 degrees, so arc CE measures 85 degrees. Make sure you are not confusing arc measure with arc length, which is very much NOT THE SAME!!

The same goes for arc DE. It is cut off by a central angle measuring 145, so arc DE measures 145 degrees. All the way around a circle, regardless of how big the circle is, is 360 degrees. Therefore, arc DC = 360 - 85 - 145 and

arc DC = 130 degrees.

Answer:

The angle of DC is 130°.

Step-by-step explanation:

Given tha total angle in a centre(O) of circle, is 360. So in order to find ∠DOC, you have to subtract 85° and 145° from 360° :

∠COD = 360° - ∠COE - ∠DOE

= 360° - 85° - 145°

= 130°

I NEED HELP ASAP

Maru [420]

Answer:

1x + 4y = 4 ⇒ 6x + 24y = 24

6x - 8y = 0 ⇒ 6x - 8y = 0

32y = 24

32 32

y = 3/4

x + 4(3/4) = 4

x + 3 = 4

-3 -3

x = 1

(x, y) = (1, 3/4)

The table shows the highest daily temperature in degrees Fahrenheit averaged over the month for Cosine City, where m is the numb

Bezzdna [24]

Answer:

Part A) The amplitude = 24

Part B) The period = 24

Part C) Vertical shift = 36

Step-by-step explanation:

The general equation of the sine function:

y = A sin (Bx) + C

Where A is the amplitude and B = 360°/Period and C is the vertical shift

See the attached figure which represents the graph of m and f(m)

So,

Part A:

The function has minimum at 12 and maximum at 60

The difference is = 60 - 12 = 48

So, The amplitude = 48/2 = 24

Part B:

Period: The period of a periodic function is the interval on which the cycle of the graph that's repeated in both directions lies.

We can deduce that the function completes one cycle within 24 months

So, the period = 24

Part C:

Vertical shift is obtained at m = 0

So, f(m) = 36

36 = A sin (0) + C

C = 36 ⇒ Vertical shift

So, The amplitude = 24

The period = 24

Vertical shift = 36
