Answer:
1. -2
2. add 25/4
3. sub 25/2
4. 5/2
Step-by-step explanation:
we conclude that the graphed equation is:
y = 4*cos(pi*x)

</h3><h3>
Which trigonometric equation is the one in the graph?</h3>
First, we can see that the graphed function is even, so we know that it wiill be a cosine.
We also can see that the maximum is 4 and the minimum is -4, so the amplitude is 4.
Then we have something like:
y = 4*cos(b*x)
To find the value of b, we can use the fact that the zeros of the function are at x = ±1/2
Then:
b*1/2 = pi/2
b = pi
Finally, we conclude that the graphed equation is:
y = 4*cos(pi*x)

Answer: $384.13 ( rounded)
Original number: $384.125
Step-by-step explanation:
Find 9.75% of Paul's original stock, to find out how much it increased.
9.75*350/100=34.125
Add $34.125 to his original stock.
$384.125
The 3 is in the one-thousandths place.
You can call this number "zero point zero zero three."
Since the 3 is in the thousandths place, this number can also be called "three thousandths."
Use the name of the number to find the ratio.
"three thousandths" means 3 out of 1000.
The ratio is 3:1000 or 3/1000.
