Answer:

geometric
arithmetic
neither (Fibonacci sequence)

Step-by-step explanation:

If ratios are the same, it is geometric:

8/4 = 16/8 = ... = 2

If differences are the same, it is arithmetic:

-4-(-8) = 0 -(-4) = ... = 4

If neither is the case, it is neither:

3-2 ≠ 5 -3

3/2 ≠ 5/3

In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)

Which is an equation of a circle with center (-10, 6) and radius 8?

kupik [55]

An equation of a circle:

(x - a)² + (y - b)² = r²

(a; b) - a coordinates of a center
r - a radius

r = 8; (-10; 6) ⇒ a = -10 and b = 6

subtitute

(x - (-10))² + (y - 6)² = 8²

Answer: (x + 10)² + (y - 6)² = 64

1.)Painting Jane is painting one wall of her living room. The wall is rectangular, 13 feet wide by 9 feet high. What is the area

antiseptic1488 [7]

Answer:

1. $117 ft^{2}$

2. $54 ft^{2}$

3. $1,428 ft^{2}$

4. $644 ft^{2}$

5. $4,700 ft^{2}$

6. $57,600 ft^{2}$

Step-by-step explanation:

First use $A = w*l$

$w = width$

$l = length$

It doesn't have to be $A = w*l$ , it could be $A = l*w$ . It will be the same answer.

1. $3 ft * 9 ft = 117 ft^{2}$

2. $3 ft * 18 ft = 54 ft^{2}$

3. $42 ft * 34 ft = 1,428 ft^{2}$

4. $23 ft * 28 ft = 644 ft^{2}$

5. $94 ft * 50 ft = 4,700 ft^{2}$

6. $360 ft*160 ft = 57,600 ft^{2}$

If y varies directly as x and x=2 when y=−4, find y when x=−6.

kakasveta [241]

Answer:

Equation: x × -2 = y

Solution: y = 12

Step-by-step explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.
