Answer:
132.6 profit
Step-by-step explanation:
13 plus 30 percent
$16.9 times 40
$676
16.9 - 30%
$11.83 times 20
$236.6 plus 676
$912.6 - 13 × 60
$912.6 - $780
132.6 profit
<u>Answer</u>
48
<u>Explanation</u>
The product of the secant and the extension of the chord is normally equivalent to square of the tangent.
From the diagram given,
The length of the secant = 2+6
= 8
Length of the extension of the chord = 6
length of the tangent = x
∴ x² = 8 × 6
= 48
Given:
The equation is

To find:
The value of x.
Solution:
We have,

Isolating the variable, we get




Therefore, the value of x is 44.2.
I got C for 6 & 7. I haven't done this in a while so I don't know 8 & 9. I hope I helped!
Answer and explanation:
We know that this is in slope-intercept form. ( y = mx + b )
1/2 would be the slope (you would use this to graph the next point)
-4 would by your y-intercept (where the line crosses the x-axis)
With this information you could graph any point using the slope given, starting at -4 (x-axis) going down or up.
