Claire keeps track of the miles per gallon her car gets per week. she has accumulated the following data:
(1, 22.42), (2, 22.84), (3, 23.26), (4, 23.68)
what is the common difference or ratio?
a. the common ratio is 0.99.
b. the common ratio is 1.02.
c. the common difference is 0.42.
d. the common difference is 0.84.

It’s 24.6 after you round to the nearest tenths the answer should be 25.0

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
