Answer:
I will do 4 questions and you can solve the rest I did.
Hope this help, thank you !!
Answer:
$84.58
Step-by-step explanation:
You would do 9.95 times 8.5 which gives you 84.575 which in money case you round to two decimal places you keep the 5 but 7 you round to 8 because "5 or more you add one more"
Hope this helps
You can obtain the graph of the function y=-2sinx-1 from the graph of the function y=sinx making such transformations:
1. <span>the multiplication by -2 increases y value twice and then symmetrically reflects the graph y=2sinx about the x-axis;</span>
2. adding -1 to the <span>y=-2sinx you translate the graph 1 unit down.
</span><span>
</span><span>On the added picture black line is a graph of y=sinx and red line is a graph of y=-2sinx-1.</span>
Check:
1. When x=0, y=-2sin0-1=-1;
2. When
![x= \frac{3\pi}{2}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20)
, then
![y=-2\sin \frac{3\pi}{2} -1=-2(-1)-1=2-1=1](https://tex.z-dn.net/?f=y%3D-2%5Csin%20%20%5Cfrac%7B3%5Cpi%7D%7B2%7D%20-1%3D-2%28-1%29-1%3D2-1%3D1)
