The sequence is a geometric sequence, because there is no common difference between the 4 terms. We would multiply by \frac{1}{2} to get to the next term, therefore proving it to be a geometric sequence.

Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –2/3x +
IRINA_888 [86]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y = - ⅔x + 12

Comparing with the general equation above

Slope = -⅔

Since the lines are parallel their slope are also the same

Slope of parallel line = - ⅔

The equation of the line using point

(6, –11) and slope - ⅔ is

y + 11 =  -  \frac{2}{3} (x - 6) \\ y + 11 =  -  \frac{2}{3} x + 4 \\ y =  -  \frac{2}{3} x + 4  - 11

We have the final answer as

y =  -  \frac{2}{ 3 } x  - 7 \\

Hope this helps you

Answer:

B. 33.7 mm; 54mm^2

Step-by-step explanation:

<em><u>To find the perimeter, use the formula:</u></em>

P = a + b + c

P = 12 + 12 + 9.7

P = 33.7

<em><u>To find area, use the formula:</u></em>

A = \frac{1}{2} bh

A = \frac{1}{2} (12)(9)

A = \frac{1}{2} (108)

A = 54

I need help fast plss
Marysya12 [62]

Answer:

a = 1√6

b = -2

Step-by-step explanation:

Hello,

To solve this trigonometric problem, we need to convert this values into fractions

a).

Sin45° = 1/√2

cos30° = √3/2

Sin60° = √3/2

Sin45° / (cos30° + sin60°) = [(1/√2) ÷ (√3/2 + √3/2)]

(1/√2) ÷ (√3/2 + √3/2)

Add √3/2 + √3/2

1/√2 ÷ 2√3/2

1/√2 × 2/2√3

2/2√(2×3)

2/2√6

1/√6

b

Cos 180° = -1

Sin150° = ½

Tan135° = -1

2cos180° - 2sin150° - tan135°

(2 × -1) - (2×½) - (-1)

-2 - 1 + 1 = -2
