formula :
-3rad × 180/π = -171.9°
Step-by-step explanation:
hope that help's you :))!!
$24.99 + $12.50m = Cost for Gym Membership
$24.99 + $12.50m = $174.99
$174.99 = $24.99 + $12.50m
$174.99 - $24.99 = $24.99 - $24.99 - $12.50m
$150.00 = $12.50m
$150.00/$12.50 = $12.50m/$12.50
12 = m
This membership will last 12 months.
Answer:
answer of 11
Step-by-step explanation:
given A=30°
R.H.S=2sinA cosA
=2 * sin30° * cos30°


=sin60°
sin 2*30°
=sin2A
L.H.S=R.H.S
<span>The Range Rule of Thumb says that the range is about four times the standard deviation. (i.e. two standard deviations to the left and two standard deviations to the right of the mean).
Given that the mean is 500 and the standard deviation is 50, then
The minimum and the maximum "usual" values are given by

Therefore, the minimun "usual" value is 400 while the maximum "usual" value is 600.

Answer: a = -1 (fourth choice)</h3>
==========================================
Work Shown:
q = (-4, 1) is one vector
r = (a,3) is another vector
The resultant vector is
q+r = (-4,1)+(a,3)
q+r = (-4+a,1+3)
q+r = (-4+a,4)
Multiply both sides by 7
7(q+r) = 7*(-4+a,4)
7(q+r) = (7*(-4+a),7*4)
7(q+r) = (-28+7a, 28)
---------------
Since 7(q+r) = (-35, 28), we know that,
(-28+7a, 28) = (-35, 28)
which leads to
-28 + 7a = -35
when we equate the x components of each vector. Let's solve for 'a'
-28 + 7a = -35
7a = -35+28
7a = -7
a = -7/7
a = -1
--------------
Check:
q = (-4,1)
r = (a,3) = (-1,3)
q+r = (-4,1)+(-1,3)
q+r = (-4+(-1), 1+3)
q+r = (-5, 4)
7*(q+r) = 7*(-5, 4)
7*(q+r) = (7*(-5), 7*4)
7*(q+r) = (-35, 28)
The answer is confirmed.
