The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the quadratic function intersecting a linear function at points (1, 0) and (3, 4)
This means that this points lie on both functions.
y = x² - 2x + 1 and 2x - y = 2
For point (1, 0):
y = 1² - 2(1) + 1 = 0; 2(1) - 0 = 2
For point (3, 4):
y = 3² - 2(3) + 1 = 4; 2(3) - 4 = 2
The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)

Hello :
x= r cos<span>θ
y= r sin</span><span>θ
r = 4 and </span>θ =<span> −3π/4
cos( </span> −3π/4 ) = cos( 3π/4 ) = cos ( π - <span>π/4) = - cos (</span><span>π/4)= - </span><span>√2/2
</span>sin( −3π/4 ) = - sin( 3π/4 ) = - sin ( π - π/4) = -sin (π/4)= - √2/2
x = - 2 √2
y = - 2 √2
Answer:
AD=DC
Step-by-step explanation:
I just took the test, and it said that this is the correct answer.
1) Calculate the whole arc (complete circumference):
Circumference = 2π*radius
radius = 6 foot
=> Circumference = 2 * 3.14 * 6 foot = 37.68
2) Calculate the time to make a whole round, by making a proportion with the two ratios:
ratio 1 = x / 37.68 =
ratio 2 = 3 / 14.13
ratio 1 = ratio 2 =>
x 3s
---------- = -----------
37.68 ft 14.13 ft
=> x = 3 * 37.68 / 14.13 = 8 s
3) Calcuate the angular velocity as the 2π rad (which is the total angle of a circle) divided by the time.
So the angular velocity is 2π rad / 8 s = 2*3.14 foot / 8 s = 0.785 rad / s
Answer: 0.785 rad / s
