Which exponential function is represented by the graph?

Jericho is a botanist and is researching about a particular species of plant. He found that the number of plants in his testing

yarga [219]

Answer:

Step-by-step explanation:

Let initial number of plants =100

Increase I year 60

Number after 1 year 160

Increase IIyear 60% 96

Number after II year 256

Increase in III year 60% 153.6

and so on

In general if t is number of years and N number of plants after n years

the expression would be

$N(t)=N_{0} (1.06)^t$

In other words, the expressions wouldbe the same as amount after t years of compound interest.

I had a summer job cooking two items at a bbq place. I sell burgers for $9.00 and sell chicken sandwiches for $11.25. Because I

pishuonlain [190]

Answer:

He sold 180 chicken sandwiches and 150 burguers.

Step-by-step explanation:

Since 330 items were sold, then the amount of burguers and chicken sandwiches sold must be equal to this value. From this information we have:

burguers + sandwiches = 330

We know that each burguer cost $9 and each chicken sandwich cost $11.25 and that we made a total of $3,375. So we have:

9*burguers + 11.25*sandwiches = 3,375

From the first equation we have:

burguers = 330 - sandwiches

Applying it on the second equation:

9*(330 - sandwiches) + 11.25*sandwiches = 3,375

2,970 - 9*sandwiches + 11.25*sandwiches = 3,375

2.25*sandwiches = 3,375 - 2,970

2.25*sandwiches = 405

sandwiches = 405/2.25 = 180

So,

burguers = 330 - 180 = 150

He sold 180 chicken sandwiches and 150 burguers.

|7| What does this mean?

Elza [17]

Absolute value of 7. Any real numbers in the absolute sign would equal to the positive value.

Definition

$\large \boxed{ |x| = \begin{cases} x \: \: \: \: (x \geqslant 0) \\ - x \: \: \: \: (x < 0) \end{cases}}$

If we substitute x = 7 in. Answer by using the definition of absolute value. Note that we only substitute x = 7 in x and not -x since 7 is greater than 0 and not less than 0.

$\large{ |7| = 7 \: \: \: \: (x \geqslant 0)}$

You may also be wondering what will happen if we substitute x = any negative numbers.

$\large{ | - 7| = - ( - 7) \: \: \: \: (x < 0)} \\ \large \boxed{ | - 7| = 7}$

Because -7 is less than 0. We substitute in -x and not x. This is the definition of absolute value. But to understand it easily, any numbers in absolute value have to equal to their positive value.

Conclusion

|7| means the absolute value of 7.
|7| is 7.
|x| is x when x ≥ 0 but -x when x < 0

Let me know if you have any doubts regarding the absolute value through comment!

13^-11x13^16x13^-3x13^^4x13^-5

Since the bases are all 13, keep the base and add the powers.
13^(-11 + 16 + -3 + 4 + -5)
13^1 = 13
