The true statements about Marcus graph are:

  • The initial cost of phone service 1 is greater than the initial cost of phone service 2
  • The unit rate of phone service 2 is greater than the unit rate of phone service 2

<h3>How to determine the true statement</h3>

From the complete question, we have the following parameters:

<u>Phone service 1</u>

  • Initial cost: $40
  • Rate: $8.50 per service

<u>Phone service 2</u>

  • Initial cost: $30
  • Rate: $10.50 per service

By comparing the above parameters:

  • The initial cost of phone service 1 is greater than the initial cost of phone service 2
  • The unit rate of phone service 2 is greater than the unit rate of phone service 2

The above statements represent the true statements about the Marcus' graph

In triangle PQR, PR = 23mm, QR = 39mm, and m&lt;R = 163 degrees. Find the area of the triangle to the nearest tenth.
Schach [20]

Answer: 131.1287 square mm (approx)

Step-by-step explanation:

The area of a triangle,

A=\frac{1}{2} \times s_1\times s_2\times sin \theta

Where s_1 and s_2 are adjacent sides and \theta is the include angle of these sides,

Here PR and QR are adjacent sides and ∠R is the included angle of these sides,

Thus, we can write,

s_1 = PR= 23\text{ mm}, s_2=QR=39\text{ mm} and \theta = 163^{\circ},

Thus, the area of the triangle PQR,

A=\frac{1}{2} \times 23\times 39\times sin163^{\circ}

A=\frac{262.257419136}{2} = 131.128709568\approx 131.1287\text{ square mm}
