Answer:

f(x)=2\cdot 3^x has fastest rate for increasing value of x

Step-by-step explanation:

Given:

g(x)=10x+15

h(x)=5x^2+x+10

f(x)=2\cdot 3^x

We are given three function to choose fastest rate for increasing value of x .

\text{Linear: }g(x)=10x+15

g(x) is linear function because the power of x is 1.

\text{Quadratic: }h(x)=5x^2+x+10

h(x) is quadratic function because power of x is 2

\text{Exponential :}f(x)=2\cdot 3^x

f(x) is exponential function because x as power.

Order of rate of increasing of growth function for increasing value of x

Exponential > Quadratic > Linear

  f(x) > h(x) > g(x)

Please see the attachment for increasing order of function.

Hence, f(x)=2\cdot 3^x has fastest rate for increasing value of x

it took heather 2/3 of an hour to read 20 pages in her library book. how long did it take her to read one page
NNADVOKAT [17]
2/3 hour .      1 hour = 60 minutes.

2/3 hour = (2/3) * 60

               = 40 minutes.

20 pages took  (2/3) hour = 40 minutes.

20 pages took her 40 minutes to read.

1 page = 40/20 = 2 minutes.

1 page took her 2 minutes to read.

Justin lives 3 2 5 miles from his grandfather's house. Enter the mixed number as a fraction greater than one. 3 2 5 =
elena-s [515]

Answer: \dfrac{17}{5} miles

Step-by-step explanation:

We can express a mixed fraction as an improper fraction.

The process is as follows:

a\dfrac{b}{c}=\dfrac{ac+b}{c}

The given mixed number = 3\dfrac25 miles

This can be represented as

3\dfrac25=\dfrac{3\times5+2}{5}\\\\=\dfrac{15+2}{5}\\\\=\dfrac{15+2}{5}\\\\=\dfrac{17}{5}>1

Hence, the required fraction= \dfrac{17}{5} miles
