Answer:

Step-by-step explanation:

an = a1 * (-2)^(n - 1)

a1 = 4

a2 = 4 * (-2)^1

a2 = 4 * -2

a2 = - 8

a3 = 4 * (-2)^(n - 1)

a3 = 4 * (-2)^2

a3 = 4 * 4

a3 = 16

an = 4 * (-2)^(n - 1)

an = 4 * (-2)^-1 * (-2)^n

an = 4/(-2) (-2)^n

an = -2 * (-2)^n

Now this is how you know. You know that a4 = - 32. So try your modified formula

a4 = - 2 * (-2)^4

a4 = -2 * 16

a4 = - 32

Can some1 pls explain to me how to do this??! Katrina is building a deck. She cuts 3 lengths of wood from a 72-inch board. The f

uysha [10]

Rewriting the question, the given lengths that were cut from the board were 30 3/4 inches, 12 1/4 inches, and 16 1/4 inches. To obtain the remaining length of the board, all of the measurements cut are to be added and subtracted from 72 inches. This is shown below:

30 3/4 + 12 1/4 + 16 1/4 = 237/4 = 59.25 inches.

Remaining length of board = 72 - 59.25 = 12.75 inches.

Therefore, there will be 12.75 inches remaining of the board.

When measuring and recording vital signs, healthcare professionals sometimes have to convert units of measurement, especially wh

Answer:

116°F = 46.67 °C and 6 Pounds = 2721.55 grams

Step-by-step explanation:

The information given in the question is 1°F = -17.22°C

1 Kilogram = 1000 grams = 2.2 pounds

And we have to convert 116° F to degrees Celsius and Six pounds to grams.

1) We know (°F-32)×5/9 =°C

So by putting the value of °F as 116 ⇒ (116-32)×5÷9 = °C

⇒ °C = $\frac{(84)(5)}{9}$

⇒ °C = 46.67

2). ∵ 2.2 Pounds = 1000 grams

∴1 Pound = 1000/2.2 = 454.54 grams

∴ 6 pounds = 6× 454.54 grams

= 2721.55 grams

Two stores are having a sale on T-shirts.Rose spends $63 for three T-shirts from store A and one from store B. Manny spends $140

Digiron [165]

Let a and b be store A and store B, respectively. Then:
3a+b=63
5a+4b=140
So
12a+4b=252
5a+4b=140
7a=112
a=16
b=15

Is line 1 (1,5) (3,-2) and like 2 (-3,2) (4,0) perpendicular of parallel?

Lera25 [3.4K]

Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So remember that perpendicular lines have slopes that are negative reciprocals to each other and parallel lines have the same slope. To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

$\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}$

Since these slopes aren't the same nor are they negative reciprocals to each other, the lines are neither parallel nor perpendicular.
