First off, we'd convert the mixed fraction to "improper" and then proceed,

\bf \stackrel{mixed}{2\frac{5}{8}}\implies \cfrac{2\cdot 8+5}{8}\implies \stackrel{improper}{\cfrac{21}{8}}\\\\
-------------------------------\\\\
\cfrac{7}{12}\div \cfrac{21}{8}\implies \cfrac{7}{12}\cdot \cfrac{8}{21}\implies \cfrac{\underline{7}}{3\cdot \underline{4}}\cdot \cfrac{2\cdot \underline{4}}{3\cdot \underline{7}}\implies \cfrac{2}{9}

Consider the function f(x) = ex and the function g(x), which is shown below. How will the graph of g(x) differ from the graph of
SIZIF [17.4K]

Answer: Option C

Step-by-step explanation:

If the graph of the function g(x)=f(x) +b  represents the transformations made to the graph of y= f(x)  then, by definition:

If b> 0 the graph moves vertically upwards.

If b the graph moves vertically down

In this problem we have the function g(x)=e^x+5 and our parent function is f(x) = e^x

therefore it is true that b =5 > 0

Therefore the graph of f(x)=e^x is moves vertically upwards by a factor of 5 units.

The answer is the Option C:  "The graph of g(x) is the graph of f(x) shifted up 5 units"

What is four over nine equal A over 45
QveST [7]
Answer: A = 20


How to Solve:

Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.

4/9 x 5

4 x 5 = 20
— -—
9 x 5 = 45

So A would be 20.


Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:

4 x 45 = 180

Then divide 180 with the 1st equation’s denominator.

180 / 9 = 20

A = 20

Which product has 4 zeros after the digit 3? 0.03 times 10 with the power of 5. 0.3 times 10 with the power of 4 0.03 times 10 w
sweet [91]

Answer:

0.3 * 10^5

Step-by-step explanation:

0.3

 ^ You need to move the three before the decimal place and leave 4 empty digits (0) between

0.3

3.0

30.0

300.0

3000.0

30000.0

A total of 5 moves.

Each move is equivalent to x, the preceding value, times 10. x * 10

Repeated multiplication times the same factor equates to exponentiation, so for a total of 5 moves, it is notated as 10^5, giving you an expression of:

0.3 * 10^5
