The focus it the point, so all you have to do is plot the focus on a graph. Then, draw a line to the point of origin and calculate the equation. This equation in slope intercept form would be y=-x+0
Answer:
-7/2
Step-by-step explanation:
![\sqrt{2y} +3=11](https://tex.z-dn.net/?f=%20%5Csqrt%7B2y%7D%20%2B3%3D11)
![\sqrt{2y} =11 -3](https://tex.z-dn.net/?f=%20%5Csqrt%7B2y%7D%20%3D11%20-3)
square both sides
2y = 64
∴ y = 64/2 = 32
The answer is option D. y = 32
6%
You want to calculate the interest on $12000 at 6% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $12000.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.06 × 5 to get that:
The interest is: $3600.00
