Intersecting chord rule:
DK x KB = AK x CK
12 x 4x+1 = 14 x 3+3x
Simplify:
48x +12 = 42x +42
Subtract 12 from each side:
48x = 42x + 30
Subtract 42x from each side:
6x = 30
Divide both sides by 6:
x = 5
Now find the length of KB: 4x +1 = 4(5) +1 = 20 +1 = 21
Now add KB and AK:
21 + 14 = 35
The answer is D. 35
Answer:
x = 5.200
Step-by-step explanation:
Given equation is,
x³ - 4.6x² - 7.03x = -20.332
x³ - 4.6x² - 7.3x + 20.332 = 0
By graphing this equation with the help of a graphing calculator,
Solutions of the equation are the points where y = 0.
In other words, x intercepts are the solutions.
Solutions for the given equation are,
x = -2.3, 1.7 and 5.2
Therefore, solution for the given equation in the interval [4, 7] is x = 5.200
