Which rule best describes the following pattern?
Oksanka [162]

Answer:

Add I, add 9, repeat.

Step-by-step explanation:

It is because if you look at the Add 9 subtract 8, repeat. it won't work

If you look at add 10, subtract 9, repeat. it its just like the first one, it won't work.

If you look at add 1, add 10, repeat, it also won't work from when you are getting 6 to 15.

So if you look at Add I, add 9, repeat., it works for all.

I don’t understand the question pls help
Alex_Xolod [135]

Answer:

AC = 15.6

Step-by-step explanation:

AC = AE + EC

By he Pythagorean theorem,

A² + B² = C²

12² + 5² = AE²

144 + 25 = AE²

AE = √169

AE = 13

Find Angle AED

tan Angle AED = 12/5

Angle AED = tan-1 (12/5)

= 67.38°

Angle AED = Angle BEC

tan (67.38°) = BC/1

BC = 2.4

1² + 2.4² = EC²

6.76 = EC²

EC = √6.76

EC = 2.6

AC = 13 + 2.6

AC = 15.6

Y2-y1 and y=me+b<br> Plzz help me with this
mestny [16]
Well if you have the coordinates (2,2) and (4,4) you plug in the y from the second cords for y2

So it would be 4-2/4-2 and 2/2 equals 1
1 would be the m in y=MX+b
Then plug one set of coords in y=MX+b
2=1x+b

I know it's confusing to understand but I tried lol

Find the angle of depression from the top of a lighthouse, 260 feet above water to a ship that's 270 feet offshore?
expeople1 [14]

Answer: OPTION C.

Step-by-step explanation:

Observe the triangle ABC attached.

Notice that the angle of depression is represented with \alpha.

Knowing that the top of a lighthouse is 260 feet above water and the ship is 270 feet offshore, you can find the value of  \alpha by using arctangent:

\alpha= arctan(\frac{opposite}{adjacent})

In this case you can identify that:

opposite=260\\adjacent=270

Therefore, substuting values into  \alpha= arctan(\frac{opposite}{adjacent}), you get that the angle of depression is:

 \alpha= arctan(\frac{260}{270})\\\\\alpha=43.92\°
