Answer:
0.07x - 0.002x^2 - 0.3
Step-by-step explanation:
Given the expression shown (0.2x-1)+(0.3-0.01x)
Expand
(0.2x-1)+(0.3-0.01x)
= 0.2x(0.3) - 0.2x(0.01x)-1(0.3) + 1(0.01x)
= 0.06x - 0.002x^2 - 0.3 + 0.01x
= 0.06x+0.01x - 0.002x^2 - 0.3
= 0.07x - 0.002x^2 - 0.3
This gives the required expression

Line n and point P are shown on the coordinate plane. What is the equation of the line parallel to line n that passes through point P?
A: y= 3x-6
B: y= 3x-6
C: y= 3x+12
D: y= -3x+3
Answer:
X = -2 - y/3
Step-by-step explanation:
First you need to know the current equation, for that:
Notice that when Y = 0, X = 2.
When Y = 6, X = 0
Therefore the equation is X = [tex]2-\frac{y}{3}[/tex]
To move that to the left of the X axis (negative direction) you just have to reduce the X number:
[tex]x=-2 - \frac{y}{3}[/tex]
Parallel lines have the same slope.
The required equation is: [tex]\mathbf{y = -3x - 6}[/tex]
The points on line n are:
[tex]\mathbf{(x,y) = (4,-6)(2,0)}[/tex]
So, the slope (m1) of line n is:
[tex]\mathbf{m_1 =\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m_1 =\frac{0--6}{2 - 4}}[/tex]
[tex]\mathbf{m_1 =\frac{6}{-2 }}[/tex]
[tex]\mathbf{m_1 = -3}[/tex]
If the line is parallel to line n, then it has the same slope (m2) as line n.
So, we have:
[tex]\mathbf{m_2 = m_1 = -3}[/tex]
Point P is given as:
[tex]\mathbf{P = (-3,3)}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m_2(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = -3(x + 3) + 3}[/tex]
[tex]\mathbf{y = -3x - 9 + 3}[/tex]
[tex]\mathbf{y = -3x - 6}[/tex]
Hence, the required equation is: [tex]\mathbf{y = -3x - 6}[/tex]

The function F is defined by F(x)= 12/x + 1/2
Use this formula to
find the following values of the function:
F(k)
F(a/2)
F(x-1)
F(2x+3)
F(x+h)
Answer:
F(2x+3) = 12/(2x+3) +1/2
Step-by-step explanation:
Put the argument of the function where the variable is. You can simplify if you want, but the original function definition is not simplified, so we assume it is not required.
F(x) = 12/x + 1/2
Put (2x+3) where x is:
F(2x+3) = 12/(2x+3) + 1/2
12/k+1/2
24/a+1/2
12/x-1+1/2

a cylindrical oil pipe measures 4 feet in diameter and 251.2 cubic feet in volume. what is the height of the oil pipe?
Answer:
Half of 4 is 2(new radius)
(finding area)
2^2 = 4
4 x 3.14 = 12.56
Now we divide
251.2 divided by 12.56 = 20 is our height.

Answer:
x = 12
Step-by-step explanation:
The angles are supplementary and add up to 180
(8x - 20) + (8x + 8) = 180
Combine like terms
16x - 12 = 180
add 12 to both sides
16x = 192
Divide both sides by16

In the circle above, LM = 2 and KL = 6.
What is the measure of MN?
A) 16
B) 10
C) 4
D) 8
Answer:
C. 4
Step-by-step explanation:
We can use power of a point to solve this problem. From this, we can set up the equation:
MN^2 = LM x MK
MK would be the sum of LM and KL because of segment addition postulate. Therefore, we can say MK = 2 + 6 = 8
Now, we can substitute the values we have in the equation above:
MN^2 = 2 x 8
MN^2 = 16
MN = 4
