Answers: a = 
, b = (0, -1), c = C, d = 0
<u>Explanation:</u>
a) Add 2π 
until you get a positive value.
+ 
= , which is located on the y-axis at 270°
b) Look at the Unit Circle to find the coordinates of = (0, -1)
c) cot = 
= 
d) = 
= 0

Answer: 471.24
<u>Explanation:</u>
angular speed (w) = 
= 4π radians/hour
linear speed (v) = r * w
= 
= 150π meters/hour
≈ 471.24 meters/hour
Since (x+90) and 4x are vertical angles, and vertical angles are congruent, you can set them equal to each other.
x+90=4x
90=3x
x=30
Step-by-step explanation:
Perimeter of a Rect.= 2(l+b)
b= x
l= 2x
Equation
152= 2(2x+x)
152= 2(3x)
152= 6x
x= 25.33
2x= 50.66
Therefore length is 50.66m and breadth is 25.33m
The solution of the set of equation is
x=6.217
y=0.132
<u>Step-by-step explanation:</u>
given the set of equations
0.7x-y=4.22(1)
5-0.8x=0.2y
-0.8x-0.2y=-5 (2)
multiply (1) and(2) by 10
7x-10y=42.2(3)
-8x-2y=-50(4)
solve (3) and (4) using elimination method
⇒-40x-10y=-250(5)
(5)-(3)
-47x=-292.2
x=6.217
substituting value of x in 3
we get y=0.132
Hello there!
Your answer is D) not justifiable, because there is another variable to consider.
While Susie may gain weight during Christmas, the holiday is not magically making her gain weight. It is more likely all of those candy canes.
I hope I helped!
