The answer is 14.4 because if the last number is 5 or higher you round up if not you round down. Then, you should get 14.40 but, the 0 isn't necessary so the answer is 14.4.
Answer:
6 degrees
Step-by-step explanation:
-3 + 9 is 6. To check this answer you can subtract 9 from 6
Answer:
540 ft^2.
Step-by-step explanation:
The area of the trapezoid = h/2 (10 + 18) = 14h.
By Pythagoras the height h = √(5^2 - 4^2) = 3.
So the area of the 2 trapezoidal bases = 2 * 14*3
= 84 ft^2.
Now we calculate the area of the four lateral rectangular sides:
= 10*12 + 18*12 + 2*5*12
= 456 ft^2.
Total area = 456 + 54
= 540 ft^2.
Do you want to solve for x and y?
What is the objective?
Answer:
![(x-7)^2+(y-2)^2=130](https://tex.z-dn.net/?f=%28x-7%29%5E2%2B%28y-2%29%5E2%3D130)
Step-by-step explanation:
The standard form of a circle is
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
where x and y are points on the circle, h and k are the center, and r is the radius. We have what we need to fill in everything but the radius, but we will solve for that like this:
![(-2-7)^2+(-5-2)^2=r^2](https://tex.z-dn.net/?f=%28-2-7%29%5E2%2B%28-5-2%29%5E2%3Dr%5E2)
Simplifying gives you
![(-9)^2+(-7)^2=r^2](https://tex.z-dn.net/?f=%28-9%29%5E2%2B%28-7%29%5E2%3Dr%5E2)
and
![81+49=r^2](https://tex.z-dn.net/?f=81%2B49%3Dr%5E2)
so ![r^2=130](https://tex.z-dn.net/?f=r%5E2%3D130)
That means the equation for this circle is
![(x-7)^2+(y-2)^2=130](https://tex.z-dn.net/?f=%28x-7%29%5E2%2B%28y-2%29%5E2%3D130)
