Y=3x-26
explanation: -33+7=-26 so that would be the y-intercept
Answer:
$295.01
Step-by-step explanation:
Using the compounding continuously formula, we are looking for A. We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4. Filling in we have:
![A=190e^{(.11)(4)}](https://tex.z-dn.net/?f=A%3D190e%5E%7B%28.11%29%284%29%7D)
Simplifying that multiplication:
.
On your calculator, raise e to the .44 power to get
A = 190(1.552707219) and
A = $295.01
Answer: 25%
Step-by-step explanation:
Original price of chocolate = $48
Price taken off for Tom = $12
i.e $12 out of $48 means Tom bought the chocolate $32
Hence, percent discount = (Price taken off/Original price) x 100%
= (12/48) x 100%
= 0.25 x 100%
= 25%
Thus, the percentage discount on the chocolate is 25%
You can write both numbers as fractions:
![6.3=\dfrac{63}{10},\quad 0.9=\dfrac{9}{10}](https://tex.z-dn.net/?f=6.3%3D%5Cdfrac%7B63%7D%7B10%7D%2C%5Cquad%200.9%3D%5Cdfrac%7B9%7D%7B10%7D)
Dividing by a fraction is the same as multiplying by its inverse, so we have
![\dfrac{63}{10}\div \dfrac{9}{10}=\dfrac{63}{10}\cdot\dfrac{10}{9}](https://tex.z-dn.net/?f=%5Cdfrac%7B63%7D%7B10%7D%5Cdiv%20%5Cdfrac%7B9%7D%7B10%7D%3D%5Cdfrac%7B63%7D%7B10%7D%5Ccdot%5Cdfrac%7B10%7D%7B9%7D)
We can cross-simplify the 10's and we have
![\dfrac{63}{10}\cdot\dfrac{10}{9}=\dfrac{63}{9}=7](https://tex.z-dn.net/?f=%5Cdfrac%7B63%7D%7B10%7D%5Ccdot%5Cdfrac%7B10%7D%7B9%7D%3D%5Cdfrac%7B63%7D%7B9%7D%3D7)
I have the problem written out (in the picture below) but tell me if it is unclear and I will better explain it to you!
