Answer:

Yes

The common difference is .6

Step-by-step explanation:

Take the second term and subtract the first term

-2.2 - (-2.8)

-2.2+ 2.8 = .6

Take the third term and subtract the second

-1.6 - (-2.2)

1.6 +2.2

The common difference is .6

Answer:

Yes

Step-by-step explanation:

-2.8, -2.2, -1.6, -1.0

-2.2-(-2.8)= -1.6 - (-2.2)= -1 - (-1.6)= 0.6

This is AP with first term -2.8 and common difference 0.6

URGENT PLEASE convert y = -5/6x -9 to standard slope form

SpyIntel [72]

Answer:

6y + 5x = -54

Step-by-step explanation:

y = m x + b -> slope-intercept form

ax + by = c -> standard form

$y = - \frac{5}{6} x - 9$

6y = -5x - 54

6y + 5x = -54

What is the equation of the line that passes through the point (-4,-3) and is perpendicular to the line 2x + 3y=15?

vlada-n [284]

Step-by-step explanation:

since it is perpendicular the eqxn be

3×-2y=c

it passes through (-4,-3) so

-12+6=c

c=-6

so eqxn becomes 3x-2y+6=0

3. A)Find the next number in the sequence.

USPshnik [31]

9514 1404 393

Answer:

1/3; geometric

Step-by-step explanation:

Apparently, your sequence is ...

81, 27, 9, 3, 1, ...

The differences between these numbers vary, but the ratio of each to the one before is a constant:

27/81 = 9/27 = 3/9 = 1/3

The sequence is geometric with a common ratio of 1/3. The next number in the sequence is (1)(1/3) = 1/3.

A circle has a circumference of 34 54 cm. What is the area of the circle to the nearest whole centimeter? Use 3.14

inysia [295]

Answer:

Step-by-step explanation:

We know that the Circumference = 3454 cm

And we also know that the formula for the Circumference of Circle is,

$2\pi \times r$

So we can put the equation this way,

$3454 = 2\pi \times r$

So we can solve for 'r'

$3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r = \frac{3454}{6.28} \\ r = 550$

Now we have radius and we can solve for the area of the circle,

$\pi \times {r}^{2}$

$3.14 \times 550 \times 550 \\ = 949850$

We can convert this to meter,

9498.5 m

I am not sure if this is correct just let me know thanks :)
