Answer:

D

Step-by-step explanation:

point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.

Y-(-1) = 2(x-1)

Y+1 = 2x-2

Y= 2x-3

Hope this helps!

Answer:

4.891

its side b (opposite side of the 50 degree angle)

Step-by-step explanation:

side c = 6

angle A is 20 side a (opposite side) = 2.184

angle B is 50 side b (opposite side) = 4.891

angle C is 110 side c (opposite side) = 6

1.

get third angle

50 + 20 = 70

180 - 70 = 110

third angle C is 110

2.

get side a

sin A/a = sin C/c

a/c = sinA/sinC

a = c * sinA/sinC

a = 6 * (sin20/sin110)

get sin in degrees

a = 6 * (.342/.9397)

a = 2.184

What is the lcm of 6and 15
Maurinko [17]
LCM stands for least common multiple. We are being asked to find the lowest multiple that 6 and 15 have in common.

Multiples of a number (n) are integers that are the product of n and another number. Let's list the multiples of both 6 and 15:

6: 6, 12, 18, 24, 30, 36

15: 15, 30, 45, 60, 75, 90

The LCM of 6 and 15 is 30.

The diagram shows a right triangle and three squares. The area of the largest square is 55 units.
Keith_Richards [23]

Answer:

A

B

C

Step-by-step explanation:

Well the sides of the smaller squares have to be greater than the biggest when put together.

a + b > c

So we need to find the square root of 55.

\sqrt{55}

≅ <u>7.4</u>

<u />

Now for option A)

srt ⇒ 12 ≅3.5

srt ⇒ 43 ≅ 6.6

3.5 + 6.6 = <u>10.1</u>

So option A is correct.

Option B)

srt ⇒ 14 ≅ 3.7

srt ⇒ 40 ≅ 6.3

3.7 + 6.3 = <u>10</u>

So option B is also correct.

Option C)

srt ⇒ 16 = 4

srt ⇒ 37 ≅ 6.1

4 + 6.1 = <u>10.1</u>

So option C is also correct.

<em>Therefore,</em>

<em>all options are correct.</em>

<em />

<em>Hope this helps :)</em>
