Start with x^2 + y^2 = r^2, where r signifies radius. Subst. 0 for x and 9 for y:
0^2 + 9^2 = r^2. Therefore, r = 9.
The std eqn is x^2 + y^2 = 9^2. this is a special case of
(x-h)^2 + (y-k)^2 = r^2 and is appropriate because the origin is at (0,0).
Answer:
1. <u>+12x</u> and <u>15</u>
2. <u>14x</u>
3. <u>2</u>
Step-by-step explanation:
Step 1: Distribute -3
To distribute -3, you would multiply both -4x and -5 by -3, changing them to 12x and 15
Step 2: Combine 12x and 2x
Then you would combine like terms, meaning that you would add 12x and 2x, creating 14x.
Step 3: Combine 15 and -13
You would finish combining like terms by adding 15 to -13, creating 2

Step-by-step explanation:
Part A: the sum of Side 1 and Side 2= 5x^2+7x-4
Part B all you have to do is the same thing, but subtract the sum of side 1 and 2 from the total. 5x^3-0x^3=? 4x^2-5x^2=? -x-7x=? -3-4=?
Part C:The closure property states that one polynomial plus another polynomial is also a polynomial. It is the same for addition, subtraction, multiplication, and division
Answer: X=5
Step-by-step explanation:
-8=(X+11)/-2
* start by multiplying both sides by -2
16=X+11
*subtract 11 from both sides
5=X
Answer:
To find the answer consider that this is a right triangle and we can use the tangent function in order to find the value of x
remember the acronym soh cah toa.
to use the tangent function we divide the opposite and adjacent side that is what the oa stands for in toa
setting it up looks like this
tan 72° = 
solving for x gives us x= 8×tan 72°
which is about 24.62
