Answer:
64π
General Formulas and Concepts:
<u>Geometry</u>
Area of a Circle Formula: A = πr²
<u>Pre-Calculus</u>
Center-Radius Form: (x - h)² + (y - k)² = r²
- (h, k) is center
- <em>r</em> is radius
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
(x - 9)² + (y - 3)² = 64
↓ Compare to Center-Radius Form
Center (9, 3)
Radius² = 64
<u>Step 2: Find Area</u>
- Substitute in variables [Area of a Circle Formula]: A = π(64)
- Multiply: A = 64π
Answer:
1) a 2) b
Step-by-step explanation:
Answer:
(f+g)(x) = 7x -1 (Answer C)
Step-by-step explanation:
Rewrite these two functions, one above the other, for ease in adding:
f(x) = 5x - 2
+g(x) =2x + 1
------------------
(f+g)(x) = 7x -1
There 7 blocks of hundreds which means each such block is equivalent to 100.
There are 5 blocks of tens, which means each such block is equivalent to 10.
There are 8 blocks of ones, which means each such block is equivalent to 1.
The total of these blocks will be = 7(100) + 5(10) + 8(10) = 758
We can make several two 3-digit numbers from these blocks. An example is listed below:
Example:
Using 3 hundred block, 2 tens blocks and 4 ones block to make one number and remaining blocks to make the other number. The remaining blocks will be 4 hundred blocks, 3 tens blocks and 4 ones blocks
The two numbers we will make in this case are:
1st number = 3(100) + 2(10) + 4(1) = 324
2nd number = 4(100) + 3(10) + 4(1) = 434
The sum of these two numbers is = 324 + 434 = 758
i.e. equal to the original sum of all blocks.
This way changing the number of blocks in each place value, different 3 digit numbers can be generated.
Use the
Binomial expansion theorem to find and simplify each
term.
Man that was a lot to type out, hopefully i helped, and Gosh I hope I get a brainly for all that freaking typing. hehe~ ^.^
