1) x-1+5[tex]\sqrt{x-1\\}[/tex]+3=0
4) [tex]x^{4}[/tex] -64=0
Answers
Answer:
See explanation below
Step-by-step explanation:
Find the value of x in each of the following
1) x-1+5√x-1+3=0
5√x-1 = -x -2
Square both sides
25(x-1) = (-x-2)^2
25(x-1) = x^2+4x + 4
25x-25 = x^2+4x + 4
x^2 +4x + 4 - 25x + 25 = 0
x^2 - 21x + 29 = 0
x = 21±√21²-4(29)/2
x = 21±√441-116/2
x = 21±√325/2
x = 21±18.03/2
x = 21+18.03/2 and 21-18.03/2
x = 19.515 and 1.485
4) x^4-64=0
x^4 = 64
[tex]x = \sqrt[4]{64}[/tex]
x = 2.83

Total profit P is defined as total revenue R minus total cost C, and is given by the function P(x)=R(x)−C(x). Find the total profit P(x) when R(x)=126.98x−0.5x2 and C(x)=3809.40+0.7x2.
Answers
Given:
The revenue function is
[tex]R(x)=126.98x-0.5x^2[/tex]
The cost function is
[tex]C(x)=3809.40+0.7x^2[/tex]
To find:
The profit function.
Solution:
We know that, the total profit P is defined as total revenue R minus total cost C.
So, the profit function is
[tex]P(x)=R(x)-C(x)[/tex]
[tex]P(x)=126.98x-0.5x^2-(3809.40+0.7x^2)[/tex]
[tex]P(x)=126.98x-0.5x^2-3809.40-0.7x^2[/tex]
[tex]P(x)=-3682.42-1.2x^2[/tex]
Therefore, the profit function is [tex]P(x)=-3682.42-1.2x^2[/tex].

Draw a line through the point (2, 0) with a slope of 1/4
Answers
Answer:
y = 1/4 x - 1/2
Step-by-step explanation:
Remark
The general equation for a line is y = mx + b
You know that m = 1/4. The problem is what do you do about (2,0)?
Solution
y = 1/4 x + b Let x = 2 when y = 0
0 = 1/4 * 2 + b multiply 2 * 1/4
0 = 1/2 + b Subtract 1/2 from both sides
b = - 1/2
equation y = 1/4 x - 1/2
