Answer:

A. -4

Step-by-step explanation:

Use the gradient formula (y2-y1)/(x2-x1)

Use the coordinates so (-2,17) = (x2, y2) and (-1, 13) = (x1, x2)

so 17-13/-2--1

= -4

A regular 18-sided polygon is rotated with the center of rotation at its center. What is the smallest degree of rotation needed

dem82 [27]

It will be easier to explain how to solve this question in a square. If you rotate 4-sided square from the centre, you need to rotate it 90 degrees. The formula for this would be: 360 ° /the side count. In a square, it would be 360° /4= 90°.

In 18-sided polygon, the calculation would be: 360°/ 18 side= 20°

hichkok12 [17]

Answer: His total rental cost will be $164.75.

Step-by-step explanation:

Since we have given that

Cost of per day = $30

Cost of per mile after the first 100 miles = $0.65

According to question, he was travelling 215 miles in 3 days.

So, it becomes,

$30\times 3+0.65\times (215-100)\\\\=90+0.65\times 115\\\\=90+47.75\\\\=\$164.75$

Hence, his total rental cost will be $164.75.
