The average cell phone bill per year was $650 in 2009. if the average cost each year is about 109.2% of the previous year (9.2% increase), what will a person pay total for a cell phone for 2009-2018? (round to nearest dollar.) question 26 options:

The cost of the bill would be $1,435.20

Step-by-step explanation:

To find this, we can determine the cost using an exponential equation.

P = 650(1.092)^x

In which x is the number of years. So, input 9 as the number of years.

P = 650(2.208)

P = $1,435.20

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
