The unit circle is defined by the equation
... x² + y² = 1
Then
... y = √(1 -x²) = √(1 -0.12²) = √0.9856
... y ≈ 0.99
<span>The answer is 25,200.
This can be solved by using proportion.
Set up the proportion as follows:
(10,800/30,000)=(x)/(70,000)
By cross multiplying you get:
(30,000)(x)=(70,000)(10,800)
x=[(70,000)(10,800)]/30,000
x=25,200 coats</span>
Answer:
<u>The correct answer is A. x = 6 + 3 √10</u>
Step-by-step explanation:
Let's solve for x:
x² - 12x + 36 = 90
Factoring this quadratic equation, we have:
(x - 6) (x - 6) = 90
(x - 6)² = 90
x - 6 = √90 (Square root to both sides of the equation)
x = 6 + √90 (Adding 6 to both sides of the equation)
x = 6 + √9 * 10
x = 6 + √3² * 10
x = 6 + 3 √10
<u>The correct answer is A. x = 6 + 3 √10</u>
25m. = 27.3403yd. of floss in the package. 27.3403yd. = 984.2508in. of floss.
If a hygenist uses 18in. of floss for each patient, 18 / 984.2508 = 54.6806 patients. Hope this helps.
Answer:
A counterclockwise rotation of 270º about the origin is equivalent to a clockwise rotation of 90º about the origin. Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.
