This doesn’t make sense if x=9 it’s not in between any of these
P is the principal amount, $12000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 3....month(s) time periods.
Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.
Do this by dividing your time, 3- month(s), by 12, since there's 12 months in 1 year.
So, t is 0.25....year time periods.
To find the simple interest, we multiply 12000 × 0.05 × 0.25 to get that:
The interest is: $150.00
Usually now, the interest is added onto the principal to figure some new amount after 3 month(s),
or 12000.00 + 150.00 = 12150.00. For example:
If you borrowed the $12000.00, you would now owe $12150.00
If you loaned someone $12000.00, you would now be due $12150.00
If owned something, like a $12000.00 bond, it would be worth $12150.00 now.
Answer:
−13x^3+2y
Step-by-step explanation:
−4x3+2y−9x3
=−4x3+2y+−9x3
=−4x3+2y+−9x3
=(−4x3+−9x3)+(2y)
=−13x3+2y
Y=x+7
Step-by-step explanation: because your slope is the x value and in the coordinates the y value is 7 and you put it in the form y=Mx+b
Consider this option:
the equation of ellipse is:
x²/a² + y²/b² = 11. if focuses are (6;0) and (-6;0), it means, that 2c=6-(-6)=12, ⇒ c=6.
2. c²=a²-b², it means, that a²-b²=36 - this is the 1st equation.
3. if c/a=3/5, it means, that c²/a²=9/25, ⇒ (a²-b²)/a²=9/25 - this is the 2d equation.
4. the 1st and the 2d equations are the system of two equations:
![\left \{ {{a^2-b^2=36} \atop { \frac{a^2-b^2}{a^2}= \frac{9}{25}}} \right. \ =\ \textgreater \ \ \left \{ {{a^2=100} \atop {b^2=64}} \right.](https://tex.z-dn.net/?f=%20%5Cleft%20%5C%7B%20%7B%7Ba%5E2-b%5E2%3D36%7D%20%5Catop%20%7B%20%5Cfrac%7Ba%5E2-b%5E2%7D%7Ba%5E2%7D%3D%20%5Cfrac%7B9%7D%7B25%7D%7D%7D%20%5Cright.%20%5C%20%3D%5C%20%5Ctextgreater%20%5C%20%20%5C%20%20%5Cleft%20%5C%7B%20%7B%7Ba%5E2%3D100%7D%20%5Catop%20%7Bb%5E2%3D64%7D%7D%20%5Cright.%20)
5. the required equation of the ellipse is:
