Answer:
D. Nine months
Step-by-step explanation:
Simple interest=principal×rate×time
Principal=$1800
Rate=4.5%
Time=?
Interest=$60.75
Simple interest=principal×rate×time
60.75=1800×4.5×t/100
60.75=8100t/100
60.75=81t
t=60.75/81
t=0.75 year
0.75 years=9 months
Answer:
The height of the cylinder is h≈2.55cm
Total of $33.53 with tax included without tax is $31.26
Since the graph is a linear function, we're going to use the slope formula solve this:
Note I am replacing m with k
![k= \frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }](https://tex.z-dn.net/?f=k%3D%20%5Cfrac%7B%20y_%7B2%7D-%20y_%7B1%7D%20%7D%7B%20x_%7B2%7D-%20x_%7B1%7D%20%7D%20)
Inserting 2 points from the graph, let's use (1,8) and (2,16).
![\frac{16-8}{2-1} ](https://tex.z-dn.net/?f=%20%5Cfrac%7B16-8%7D%7B2-1%7D%0A%0A%20)
k=8
