Two functions f and g are given. Show that the growth rate of the linear function is constant and that the relative growth rate
joja [24]

Answer:

  linear function growth rate: 8.5

Step-by-step explanation:

The growth rate of the linear function is the coefficient of t: 8.5. (It is a constant.)

__

The growth rate of g(t) is its derivative: g'(t) = (1/8)(160e^(t/8)) = 20e^(t/8). Then the relative growth rate is ...

  g'(t)/g(t) = (20e^(t/8))/(160e^(t/8)) = 20/160 = 1/8

It is a constant.

If a = 12 and 120% of a is equal to 80\% of bthen what is a + b ?
Novosadov [1.4K]

Answer:

The answer is 30

Step-by-step explanation:

First you have to find 120% of a (12).

\frac{12}{1}  \times  \frac{120}{100}  = 14.4

Therefore; 14.4 is 80% of b, and we are trying to find 100% of b

14.4 = 80\% \\ x = 100\%

we do not know what is 100% therefore we call it *x*. In order to find this unknown value *x* we cross multiply.

14.4 \times 100\% = 80\% \times x

This is the same as saying;

14.4  \times 1 = x \times  \frac{4}{5}

100% percent would be 1 because it is the whole number we are trying to find. The 80% would be 4/5. To get 4/5 you can simply break down 80/100 ( this is 80% as a fraction).

so the new equation is: 14.4= 4/5x

We divide both sides by 4/5. Then we will get x tobe equal to 18. Therefore b is 18. We were asked to find (a + b) so.<em> </em><em>1</em><em>8</em><em>+</em><em>1</em><em>2</em><em> </em><em>=</em><em> </em><em>30</em>
