There are two functions that can be used to describe the percent of people 25 years and older who have completed at least high s
Korvikt [17]

Answer:

g(15)=93.8\%

see the explanation

Step-by-step explanation:

Let

x ----> the number of years since 2008,

g(x) ----> the percent of people 25 years and older who have completed at least high school

we know that

g(x)=0.008x^2+0.42x+87.5

so

For x=15 years since 2008

substitute

g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%

That means

In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%

We can calculate the speed of the boat with (333km/7 hours) = 47.57 km/hr.

Assuming the same speed, the boat would travel (47.57 km/hr)*(6 hr) = 258 km

Which function has a graph with a vertical
raketka [301]

Answer:

f(x)=\frac{1}{x-7}-3, see the graph attached for a visual reference.

Step-by-step explanation:

Vertical asymptotes are only present in rational functions where the parent function f(x)=\frac{1}{x} has a vertical asymptote at the line x=0 and a horizontal asymptote at the line y=0. Because the vertical asymptote has to be x=7, the denominator must be x-7 in order for the denominator to equal 0. For the horizontal asymptote to be y=-3, then 3 must be subtracted from the rational function. Therefore, the function that has these asymptotes is f(x)=\frac{1}{x-7}-3.
