Answer:

1. 3-4-5 method

2. Rope method

3. Optical square method

Step-by-step explanation:

1. A measuring tape, two ranging poles, pegs and three person's are needed.

First person holds together btw thumbs and finger the zero mark, the second person holds between thumb and finger the 3m mark on the tape and the third person holds the 8m, when all sides of the rope are stretched, a triangle is formed and angle near one is a right angle.

2. One loop of the rope is placed around peg A with a peg through other loop make a circle on the ground place peg B & C where circle crosses the base line and peg D is place half way between peg B & C, allowing peg D & A to form lines perpendicular to base line thereby forming a right angle.

3 this are simple instruments used to set out right angles and they are single and double prismatic square.

What is the pattern in the values as the exponents increase?
nirvana33 [79]

Answer:

"Multiply the previous value by 2"

Step-by-step explanation:

Let's check the first 2 terms for all the answer choices.

1. Add \frac{1}{16} to the previous value:

\frac{1}{32}+\frac{1}{16}=\frac{3}{32}

Doesn't match.

2. Subtract \frac{1}{16} from the previous value:

\frac{1}{32}-\frac{1}{16}=-\frac{1}{32}

Doesn't match.

3. Divide the previous value by 2:

\frac{\frac{1}{32}}{2}\\=\frac{1}{32}*\frac{1}{2}=\frac{1}{64}

Doesn't match.

4. Multiply the previous value by 2:

\frac{1}{32}*2=\frac{2}{32}=\frac{1}{16}

DOES WORK!

Also, doing the same thing with all the other values would give us matching answer. So this choice is right.

Answer:  \bold{-\dfrac{1}{2}}

<u>Step-by-step explanation:</u>

Average rate of change is the slope (m) between the two coordinates (-1, -1) and (1, -2).

m=\dfrac{y_2-y_1}{x_2-x_1}

m = \dfrac{-2+1}{1+1}

   =-\dfrac{1}{2}

Pls help I have no clue
suter [353]

Step-by-step explanation:

y-2 = - 3(x-3)

y - 2 =-3x +9

y -2 +2 = - 3x +9 +2

y = - 3x +11

To find the the coordinate

When x =0

y = - 3(0) +11

y= 11

When y = 0

0 = - 3x +11

Subtract 11 from both sides

-3x = - 11

x = 11/3

The y intercept is 11 so, one of your points will be at (0, 11) while the other will be at (11/3, 11).
