Step-by-step explanation:
im not sure... did you figure it out?!?!
Answer:
a7 = 12, a11= 47
Step-by-step explanation:
768, 384, 192, 96, 48, 24, 12
a(n) = 768 / (2∧X - 1)
a(7) = 768 / 2∧6 = 768 / 64 = 12
7, 11, 15, 19 23, 17, 31, 35, 39, 43, 47
a(n) = 7 + 4 * (X-1)
a(11) = 7 + 4 * (11-1) = 7 + 40 =47
The answer is B because the y is clearly shows the intercept is 1
<h2><u>Circle Equations</u></h2>
<h3>Write the equation of a circle in standard form for the following:</h3><h3>x² − 14x + 49 + y² + 4y = 0</h3>
To write the general form of a circle into standard form, use the formula
<em>(x - h)² + (y - k)² = r²</em>
Where,
<u>(h, k)</u> is the center; and
<u>r</u> is the radius
To transform general form to standard form, group the terms that has the same variables. Replace 0 with the constant term.
- x² - 14x + 49 + y² + 4y = 0
- (x² - 14x) + (y² + 4y) = -49
Next step is to complete the square of each equation inside the parentheses.
- (x² - 14x) + (y² + 4y) = -49
- (x² - 14x - 49) + (y² + 4y + 2) = -49 - 49 + 2
Then factor each equation inside the parentheses.
- (x² - 14x - 49) + (y² + 4y + 2) = -49 - 49 + 2
- (x - 7)² + (y + 2)² = √2
- (x - 7)² + (y + 2)² = 4
<u>Answer:</u>
- The standard form of the circle is <u>(x - 7)² + (y + 2)² = 4</u>.
