If you can exchange 104.51 us dollars for 1,322.14 mexican pesos, what is the exchange rate of the us dollar to the mexican peso, to three decimal places?
a.
1: 12.650
b.
1: 1.427
c.
1: 0.079
d.
1: 0.008

 Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Amount he exchange in US dollars = 104.51

Amount he exchange for Mexican pesos = 1322.14

So, exchange rate of the US dollar to the Mexican pesos, to three decimal places is given by

Hence, the exchange rate of the US dollar to Mexican peso is

1:12.650.

Therefore, Option 'a' is correct.

step-by-step explanation:

b and c

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
