Answer:
y = -1/4x + -6
Step-by-step explanation:
Answer:
y = 30x + 75
Step-by-step explanation:
every month you're paying 30 dollars for a fee.
the 75 dollars is simply the "down payment" so to say.
m is the constant growth or the continuous growth or the charge per month.
Answer
I think the answer is C if its not then say the answer in the comments.
Step-by-step explanation:
The answer is <span>B.154/d = 44/14
</span>
<span>In a circle, the circumference (C) and diameter (D) vary directly:
C = kD
k = C/D
Circle 1: k = C1/D1
Circle 2: k = C2/D2</span>
C1/D1 = C2/D2
C1 = 154
D1 = ?
C2 = 44
D2 = 14
154/D1 = 44/14
So, the choice B. is correct.
The solutions appear to be
{π/2, 2π/3, 4π/3}.
_____
Replacing sin(2x) with 2sin(x)cos(x), you have
2sin(x)cos(x) +sin(x) -2cos(x) -1 = 0
sin(x)(2cos(x) +1) -(2cos(x) +1) = 0 . . . . factor by grouping
(sin(x) -1)(2cos(x) +1) = 0
This has solutions
sin(x) = 1
x = π/2and
2cos(x) = -1
cos(x) = -1/2
x = {2π/3, 4π/3}
