Hello :
let : z = 4-3ii z' = -2+7i
the distance between the points 4-3i and -2+7i is : <span>|z - z' |
</span> |z - z' | = |4-3i+2-7i| = |6-10i | =√(6²+(-10)²) =√136
Answer:
630 minutes.
Step-by-step explanation:
That would be the lowest common multiple of 10, 14 and 18
10 = 2 x 5
14= 2 x 7
18 = 2 x 3 x 3
The LCM = 2 x 3 x 3 x 5 x 7
= 630.
Answer:
The linear regression model is
.
Step-by-step explanation:
The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.
From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.
The general linear regression model is

Using technology we get


Put a=-2.19 and b=-8.92 in the above equation.

Therefore the linear regression model is
.
Answer:
Y = W = 15 ft.
X= L = 60 ft.
So width is 15 and the length is 60.
