Pluto has been hard to measure from earth because of its atmosphere. in 2007 young, young, and buie measured pluto as having a diameter of 2322 km. in 2015 the new horizons probe reached pluto and measured it up close and we now know the actual diameter is 2372 km. what was the percent error of the 2007 measurement?

2.15% was the percent error of the 2007 measurement.

Step-by-step explanation:

To calculate the percentage error, we use the equation:

We are given:

Experimental value of diameter of Pluto ,2015= 2372 km

Theoretical value of diameter of Pluto, 2007 = 2322 km

Putting values in above equation, we get:

Hence, 2.15% was the percent error of the 2007 measurement.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
