Answer:
Sqrt 80 = 8.94
Step-by-step explanation:
d = sqrt[(x-x)^2 + (y-y)^2]
d = sqrt [(6-2)^2 + (-9 - - 1)^2]
d = sqrt [(4)^2 + (-8)^2]
d = sqrt (16 + 64)
d = sqrt 80
d = 4 sqrt 5 = 8.94

Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a

Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula



Next, is to determine the formula using:

<em>Considering :When x = 0; y = 39000, we have</em>
<em />
<em />
<em />
<em />
<em>Make y the subject of formula</em>
<em />
<em />
<em />
<em>Express y as a function of x</em>
<em />
<em />
Solving (b): Income in 2005
<em>In 2005, x = 15</em>
So:
becomes


Answer:
m∠A = 65°
Step-by-step explanation:
<em>Opposite angles of the quadrilateral add up to 180</em>.
This means x + 148 = 180 -> <em>x = 32</em>.
m∠A = 2x + 1 -> 2(32) + 1
m∠A = 65°.
