Exponential model word propiems
Of all eligible voters in your county, 70% are currently registered to vote.
A recent poll predicts that the relationship between V, the percentage of all eligible voters who are registered to
vote, and t, the number of years from now will be modeled by the following equation.
V = 100 - 30.e-0.047
In how many years will 80% of all eligible voters in your county be registered to vote?
Give an exact answer expressed as a natural logarithm.
years

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
