Answer:
<em>( 4, 11 ) , ( - 4, 27 ) </em>
Step-by-step explanation:
f(x) = x² - 2x + 3
f(x) = - 2x + 19
x² - 2x + 3 = - 2x + 19
x² - 16 = 0
( x + 4 )( x - 4 ) = 0
= - 4
= 4
f(x) =
= - 2( - 4 ) + 19 = 27
= 27
f(x) =
= - 2( 4 ) + 19 = 11
= 11
<em>( 4, 11 ) , ( - 4, 27 )</em>
Answer:
2, 120 degrees
Step-by-step explanation:
The first step in finding the polar form is finding the modulus, r
r= sqrt( x^2 + y^2)
r = sqrt( (-1)^2 + sqrt(3)^2)
r = sqrt(1+3)
r= sqrt(4)
r =2
The next step is finding the angle
theta = arctan (y/x)
theta = arctan (sqrt(3)/-1))
theta = arctan (-sqrt(3))
theta = -60
The point (-1, sqrt(3)) is in the 2nd quadrant, but our angle is in the 4th quadrant, so we add 180 degrees
theta = -60 + 180 = 120
theta = 120 degrees
Answer:
D: 768
Step-by-step explanation:
First, he divides a piece of paper in half.

He gets two pieces.
Next, he cuts each of the pieces into three parts.

Thirdly, he cuts each of the 6 pieces into 8 pieces.

Lastly, he divides each piece into 16 parts.

He has 768 pieces in the end. (D)
