<h2><u>Full Question:</u></h2>

Which definition for a ligament did you think was better? Explain. 1- A ligament is made up of tissue that forms a band. 2- A ligament is a band of tough tissue connecting bones or holding organs in place.

<h2><u>Answer:</u></h2>

A ligament is a band of tough tissue connecting bones or holding organs in place is the better definition.

Option B

<h3><u>Step-by-step explanation:</u></h3>

Ligament is a type of connective tissue which develops from the mesoderm. Its actually a tough band containing mostly collagen tissue. Ligament joins two bones which forms a joint.

Ligament is formed of collagen fibres which run parallel to each other and this forms a band. It's very tough and this is why, it can hold bones together.

Ligaments that hold organs are actually pseudo ligaments which are actually folds of peritonium that holds the organs in place.

Tiffany started a doggle daycare where she offered a variety of services, including grooming. She charges an hourly rate of
puteri [66]

The linear function in slope-intercept form for the cost of a visit of x hours is given as follows:

C(x) = 9x + 31.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, the rate means that the slope is of m = 9. When x = 3, C(x) = 58, hence the y-intercept is found as follows:

C(x) = 9x + b

58 = 9(3) + b

b = 31.

Hence the equation is:
C(x) = 9x + 31.

What are the solutions of x^2-3x+3=0
deff fn [24]

<em><u>The solutions to quadratic equation are:</u></em>

x = \frac{3 + i \sqrt{3}}{2}\\\\x = \frac{3 - i \sqrt{3}}{2}

<em><u>Solution:</u></em>

<em><u>Given is:</u></em>

x^2 - 3x + 3 = 0

We have to find the solutions to quadratic equation

\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\\\x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\mathrm{For\:}\quad a=1,\:b=-3,\:c=3:\\\\x=\frac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\cdot \:1\cdot \:3}}{2\cdot \:1}

x=\frac{3 \pm \sqrt{\left(-3\right)^2-4\cdot \:1\cdot \:3}}{2\cdot \:1}\\\\x = \frac{3 \pm \sqrt{-3}}{2}\\\\x = \frac{3 \pm i \sqrt{3}}{2}

<em><u>We have two solutions :</u></em>

x = \frac{3 + i \sqrt{3}}{2}\\\\x = \frac{3 - i \sqrt{3}}{2}
