Answer:
C:30π cm
Step-by-step explanation:
The formula for the circumference of a circle is
C = 2πr
Since the radius is 15 cm, this makes 2r = 2(15) = 30 cm. This makes the circumference
C = 30π cm
Answer:
B and D
Step-by-step explanation:
(2x-6):(6x-4)
you can divide everything by 2
2x÷2=x, -6÷2=-3
6x÷2=3x, -4÷2=-2
so it's B X-3:3x-2
(2x-6):(6x-4)
multiply everything by 2
2x × 2 = 2x, -6 × 2 = -12
6x × 2 = 12x, -4 × 2 = -8
so it's D (4x-12): (12x-8)
Answer:
question seems incomplete but with the limited information one can deduce that the professor was trying to investigate how students CGPA is affected by the length of period spent on video games.
A
Step-by-step exp
independent variables are constants. they do not change or depend on any other variable.
dependent variables, they do depend on other variables, we call them resulting variables..
Answer:
A = (3,-2)
reflect along the y -axis ; set x=-x
(-3,-2)
reflect along the x-axis ; set y=-y
A' = (-3,2)
Same for B,C and D
ABCD is reflected across the y-axis and then the x-axis.
