Answer:
36 <127
(36,127°)
36 [ cos (127) + i sin (127)]
Step-by-step explanation:
w1 = 2 < 95
w2 = 18 < 32
w1 * w2
We multiply the magnitude and add the angles
w1 * w2 = 2*18 < (95+32)
=36 < 127
36 [ cos (127) + i sin (127)]
Answer:
9 ft
Step-by-step explanation:
<h3>a²+b²=c²</h3><h3>a²+12²=15²</h3><h3>a²+144=225</h3><h3>225-144=81</h3><h3>√81=9</h3>
Answer:
Step-by-step explanation:
Substitute with x and y with 3:-
First, Multiply -1 and 3 = -3
Subtract 7 from -3 = -10
Multiply 2 and -10 = -20

Let the width be w, then length = w + 4
Area = length x width = w(w + 4) = w^2 + 4w
f(w) = w^2 + 4w
for w = 8 in
Area = (8)^2 + 4(8) = 64 + 32 = 96 in^2
Find the mean of all values ... use it to work out distances ... then find the mean of those distances!
In three steps:
1. Find the mean of all values
2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)
3. Then find the mean of those distances
