The answer is 24 ways.
Answer:
Yes, it will fit snugly in a 90º corner
Step-by-step explanation:
To do this, we simply need to check if the given sides of the shelf is right-angled.
So, we have:
To check for right-angle triangle, we make use of:
This gives:
This shows that the given sides of the shelf is a right-angled triangle.
Hence, it will fit the wall
Answer:
and
Step-by-step explanation:
The standard equation of a circle is where the coordinate (h,k) is the center of the circle.
Second Problem:
- We can start with the second problem which uses this info very easily.
- (h,k) in this problem is (-2,15) simply plug these into the equation.
.
- We can also add the radius 3 and square it so it becomes 9. The equation.
- This simplifies to
.
First Problem:
- The first problem takes a different approach it is not in standard form. But we can convert it to standard form by completing the square.
first subtract 37 from both sides so the equation is now
.
to both the x and y portions of this equation you can complete the squares.
and
which equals 49 and 4.
- Add 49 and 4 to both sides and the equation is now:
You can simplify the y and x portions of the equations into the perfect squares or factored form
and
.
- Finally put the whole thing together.
.
I hope this helps!
