Answer:
$800
Step-by-step explanation:
We first need to turn 8% into a decimal:
8% ->
-> 0.08
Next, multiply 10,000 by 0.08:
![x=10,000(0.08)](https://tex.z-dn.net/?f=x%3D10%2C000%280.08%29)
![x=800](https://tex.z-dn.net/?f=x%3D800)
The salesperson earned $800 worth of commission this month.
Answer: A: Whole Number B:Integer and C: Rational are all correct.
For the question: In the figure, AB is divided into equal parts. The coordinates of point A are (2, 4), and the coordinates of point B are (10, 6). Match each pair of coordinates to the corresponding point on AB.
Answer:The coordinates of the point are (6 , 5).
For the question: Imani and Abedi drive to work. Imani drives 66 miles in 1.5 hours. Abedi drives 56 km in 1 hour 15 min. Work out the difference between their average speeds in km/h. 1 mile = 1.6 km
Answer:25.6 km/h
I couldn't help you on all of them, but I helped you on some. Hope this helps :D
So, here we have an exponential function.
Remember that an exponential function has the form:
![y=a(b)^x=a(1\pm\frac{r}{100})^x](https://tex.z-dn.net/?f=y%3Da%28b%29%5Ex%3Da%281%5Cpm%5Cfrac%7Br%7D%7B100%7D%29%5Ex)
Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that
![\begin{gathered} a=40 \\ b=1+\frac{13}{100}=1.13 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a%3D40%20%5C%5C%20b%3D1%2B%5Cfrac%7B13%7D%7B100%7D%3D1.13%20%5Cend%7Bgathered%7D)
So,
![f(x)=40(1.13)^x](https://tex.z-dn.net/?f=f%28x%29%3D40%281.13%29%5Ex)
For city B:
![\begin{gathered} a=40 \\ b=1+\frac{16}{100}=1.16 \\ g(x)=40(1.16)^x \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a%3D40%20%5C%5C%20b%3D1%2B%5Cfrac%7B16%7D%7B100%7D%3D1.16%20%5C%5C%20g%28x%29%3D40%281.16%29%5Ex%20%5Cend%7Bgathered%7D)
But something different happens with city C. This is not an exponential function, this is a linear function.
So,
![h(x)=40+10x](https://tex.z-dn.net/?f=h%28x%29%3D40%2B10x)
To figure out the cost per cookie, divide $2.49 by 3. The cost per 1 cookie (column 1) would be .83 cents.
To figure out the cost of 20 cookies, multiply 20 x .83 cents. The answer is 20 cookies would cost $16.60
To figure out how many cookies would cost $145,25, divide $145.25 by .83 cents. The answer is 175 cookies would cost $145.25
