Answer: x^(2)-3x-28=0
Step-by-step explanation:
The points of intersection for the two functions and round to the nearest tenth are (0.5, 1.4) and (4.85, -0.3)
<h3>System of equations</h3>
Given the following function
f(x) = - 0.5x + 2
g(x) = x^3 - 5x^2 + 3
The point of intersection is the point where f(x) = g(x)
x^3 - 5x^2 + 3 = - 0.5x + 2
x^3 - 5x^2 + 3 + 0.5x - 2 = 0
x^3 - 5x^2 + 0.5x + 1 = 0
Factorize and determine the value of x
x = 0.53 and 4.85
If x = 0.53
f(0.53) = -0.5(0.53) + 2
f(0.53) = -0.265 + 2
f(0.53) = 1.375
If x = 4.85
f(4.85) = -0.5(4.85) + 2
f(4.85) = -2.425 + 2
f(4.85) = -0.245
Hence the points of intersection for the two functions and round to the nearest tenth are (0.5, 1.4) and (4.85, -0.3)

Answer:
45350
Step-by-step explanation:
(8)(20)+(8)(6)(8)+20(8+6)(8)(20)+6
=160+(8)(6)(8)+20(8+6)(8)(20)+6
=160+(48)(8)+20(8+6)(8)(20)+6
=160+384+20(8+6)(8)(20)+6
=544+20(8+6)(8)(20)+6
=544+(20)(14)(8)(20)+6
=544+(280)(8)(20)+6
=544+(2240)(20)+6
=544+44800+6
=45344+6
=45350
