Can you solve this problem so that you can explain me as best as possible to understand the problem?

Alchen [17]

Answer:

Answer: 2

Step-by-step explanation:

$\frac{2}{3} (4 \frac{1}{6} - \frac{7}{6} ) \\$

express the mixed fraction into proper fraction:

${ \boxed{4 \frac{1}{6} = \frac{(6 \times 4) + 1}{6} = \frac{25}{6} }}$

then solve simplify:

$= \frac{2}{3} ( \frac{25}{6} - \frac{7}{6} ) \\$

solve the bracket:

$= \frac{2}{3} ( \frac{25 - 7}{6} ) \\ \\ = \frac{2}{3} ( 3)$

then simplify:

$= \frac{2 \times 3}{3} \\ \\ = 2$

Given the following exponential function, identify whether the change represents growth or decay , and determine the percentage

jenyasd209 [6]

Answer:

It is growth and the percentage rate of increase is 7.5%

Step-by-step explanation:

The exponential equation is as follows;

y = 550(1.075)^x

Now, I can identify that the exponential equation is that of growth.

This is because what is in the bracket i.e can be represented as 1+ 0.075

The 0.075 represents the margin of increase as we move on from one value to another

The percentage rate can be gotten by expressing 0.075 as a percentage

That would be expressing is as a fraction

This is just 7.5/100 which means what we have is 7.5%
