First we need slope

  • C=(0,0)
  • D(7,12)

\\ \sf\longmapsto m=\dfrac{12-0}{7-0}

\\ \sf\longmapsto m=\dfrac{12}{7}

Put D co-ordinates on y=mx+b

\\ \sf\longmapsto 12=\dfrac{12}{7}(7)+b

\\ \sf\longmapsto 12=12+b

\\ \sf\longmapsto b=12-12

\\ \sf\longmapsto b=0

Now

slope intercept form.

\\ \sf\longmapsto y=\dfrac{12}{7}x

  • As b=0

Answer:

• General equation of a line:

{ \rm{y = mx + b}}

Consider end points of line CD: (0, 0) and (7, 12):

• find the slope, m:

{ \rm{slope =  \frac{y _{2} - y _{1}  }{x _{2}  - x _{1} } }} \\  \\ { \tt{m =  \frac{12 - 0}{7 - 0} }} \\  \\ { \underline{ \tt{ \:  \: m =  \frac{12}{7}  \:  \: }}}

• using end point (0, 0), find the y-intercept, b:

{ \rm{y = mx + b}} \\  \\ { \rm{0 = ( \frac{12}{7}  \times 0) + b}} \\  \\ { \tt{b = 0}}

• therefore, equation of line CD is;

{ \boxed{ \boxed{ \tt{ \:  \: y =  \frac{12}{7}x \:  \:  }}}}

Answer:

  • The diagonals of a parallelogram bisect each other.

Step-by-step explanation:

If one pair of consecutive sides of a parallelogram is congruent, then the parallelogram is a rectangle.

  • False. This is rhombus.

The diagonals of a parallelogram bisect each other.

  • True

If a quadrilateral has four right angles, then it is a square.

What is the greatest possible error if irina measured the length of her window as 3.35 feet? 0.5 0.05 0.005 0.0005
AlladinOne [14]

3.35 feet have a maximum inaccuracy of 0.005 feet.

The correct option is C.

<h3>What is error analysis?</h3>

When students consistently commit mistakes, an approach known as error analysis is frequently employed to determine the root of the problem. Reviewing student work is the first step in the process, after which misunderstood patterns are sought out. Mathematics mistakes can be conceptual, procedural, or factual, and they can happen for a variety of reasons.

<h3>Given:</h3>

The window is 3.35 feet long.

Find the biggest error you can

<h3>According to the given data:</h3>

Half of the measuring unit is considered to be the maximum amount of measurement error.

3.35 feet are calculated to the nearest centimeter, or 0.01 feet

Consequently, the largest conceivable error is equal to half of the measurement unit.

= .01/2

= .005

Therefore, the maximum inaccuracy for 3.35 feet is 0.005 feet.

The length of a rectangular park is 3 feet shorter than times its width. If the length is 123 feet, what is the width of the par
VLD [36.1K]

Answer:

Width is 120ft but may be different if the "times the width" information is given. Follow the same process.

Step-by-step explanation:

To solve the problem, write an expression that relates length and width using the information given to you. "The length of a rectangular park is 3 feet shorter than times its width" means that l = 3 + w. Since no number is given for "times its width" we disregard this portion. If you have the information then you would include it here l = 3 + _w.

So using the expression l = 3 + w, substitute l = 123. Then the width will be:

l = 3 + w

123 = 3 + w

120 = w
