Find the distance between Line L and Point P if Line L contains the points
(6, 4) and (3, 2) and Point P is (9, 11).
• 6.4
• 4.2
• 8.9
• 11.3
Answer:
(b) 4.2
Step-by-step explanation:
The distance from a point to a line can be found using the formula. To use it, we need the equation of the line in general form.
We notice that the coordinates of the given points have the same y/x = 2/3 ratio. This means they lie on the line y = 2/3x. The equation for that line, written in general form is ...
y = 2/3x
3y = 2x
2x -3y = 0 . . . . . . general form equation for the line through the points.
The formula for the distance from (x, y) to the line ax+by+c=0 is ...
d = |ax +by +c|/√(a²+b²)
The distance from (x, y) to our line is given by the formula ...
d = |2x -3y|/√(2² +(-3)²)
d = |2x -3y|/√13
For point P(9, 11), the distance to the line is ...
d = |2·9 -3·11|/√13 = |18 -33|/√13 = 15/√13 ≈ 4.2
The system of equations below has no solution. Which equation could represent a linear combination of the system? lm *+¿x= 15 = 42 4x + 15 y = 12 0 0 = -78 DO 15 -y=33 2 O0=0

Factor the expression: 16a + 10
Answer:
2(8a + 5)
Step-by-step explanation:
Hi there!
16a + 10
The two terms here are 16a and 10. Both of them are divisible by 2. Factor 2 out of the terms:
= 2(8a + 5)
Now, there are no more common factors between 8a and 5. Therefore, this expression is now fully factored.

Answer:
f(x) = 2e^(x^3/3) +1
Step-by-step explanation:
This is called a "separable" differential equation, because the variables can be separated:
[tex]\dfrac{dy}{y-1}=x^2\cdot dx[/tex]
Now, both sides can be integrated.
[tex]\displaystyle \int{\dfrac{dy}{y-1}}=\int{x^2}\,dx\\\\\ln(y-1)=\dfrac{x^3}{3}+c_1\\\\y-1=c_2\cdot e^{x^3/3}\qquad c_2\text{ is a free constant different from $c_1$}\\\\3=c_2e^0+1\qquad\text{apply initial condition to find $c_2=2$}\\\\\textsf{Add 1 to get y alone. Use the found value of $c_2$. Replace $y$ with $f(x)$.}\\\\\boxed{f(x)=2e^{x^3/3}+1}[/tex]

the volume of a right cone is 264 π units. if its circumference measures 12 π units, find its height
QUICK PLEASE!!
Answer:
r = [tex]\frac{12\pi }{\pi }[/tex] / 2 = 6
volume = 1/3 * π * r² * h
h = 3 * V/π * [tex]r^{2}[/tex]
h = [tex]\frac{3 * 264\pi }{\pi * 6^{2} }[/tex] = 22
The height of the right cone is 22 units.
What is a right cone?'A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.'
According to the given problem,
Radius of the right cone = [tex]\frac{\frac{12\pi }{\pi } }{2}[/tex]
= 6 units
Volume of the right cone = [tex]\frac{\pi r^{2}h }{3}[/tex]
Solving for h,
h = [tex]\frac{3*264\pi }{\pi *6^{2} }[/tex]
⇒ h = 22 units
Hence, we can conclude that the height of the right cone is 22 units.

Step-by-step explanation:
Basically, find the missing side lengths of each triangle so that you can solve for x:
1. right triangle w/ side lengths 48 and 52
48^2 + (missing side)^2 = 52^22304 + (missing side)^2 = 2704(missing side)^2 = 400(missing side) = 20 (use this for next triangle)2. right triangle w/ side lengths 12 and 20 (from previous triangle)
12^2 + (missing side)^2 = 20^2144 + (missing side)^2 = 400(missing side)^2 = 256(missing side) = 16 (will be used with next triangle's missing side)3. right triangle w/ side lengths 5 and 13
5^2 + (missing side)^2 = 13^225 + (missing side)^2 = 169(missing side)^2 =144(missing side) = 12Take right triangle w/ side lengths 12, 20, and 16 (#2) and right triangle w/ side lengths 5, 13, and 12 (#3):
the value of 12 (missing side of #3) subtracted from the #2's missing side, 16, (not its hypotenuse that equals 20 which was found from #1) will equal the missing side length that will be used to find 'x'16 - 12 = 4 ---> so the side lengths are 4, 5, and x4. Solve for the final triangle that includes x:
4^2 + 5^2 = x^216 + 25 = x^241 = x^2[tex]\sqrt{41}[/tex] = xUse the drawing tools to form the correct answer on the graph.

4 << 10
Answer:
The correct solution is f + goh = x² + 6x +1
Step-by-step explanation:
f (x) = x^2
g(x) = 3x + 1
h(x) = 2x
We are to look for f + (goh)
First we need to get the composite function goh
goh = g(h(x))
g(h(x)) = g(2x)
To get g(2x) we will substitute x in g(x) as 2x as shown below:
Given g(x) = 3x+1
g(2x) = 3(2x)+1
g(2x) = 6x+1
f + goh = x² + (6x +1)
f + goh = x² + 6x +1
Jim wrote goh as 2(3x+1) instead of 3(2x) + 1. The composite function that Jim looked for was hog not goh.
The correct solution is f + goh = x² + 6x +1

Which of the following is a factor of 5x3 - 135?
Answer:
[tex]5 (x - 3)( {x}^{2} + 3x + 9)[/tex]
Step-by-step explanation:
[tex]5 {x}^{3} - 135 \\ \\ = 5 \{ {x}^{3} - 27 \}\\ \\ = 5 \{ {x}^{3} - {(3)}^{3} \}\\ \\ = 5 (x - 3)( {(x)}^{2} + (x)(3) + {(3)}^{2} )\\ \\ = 5 (x - 3)( {x}^{2} + 3x + 9)[/tex]
Answer: If the question is asking to find the factor of 5x^3-135 then the answer is:
5(x-3)(x^2+3x+9)
Step-by-step explanation:
First, factor out the common term (x^3-27)
5(x^3-27)
Then, factor (x^3-27)
(x-3)(x^2+3x+3^2)
3^2 = 9
5(x-3)(x^2+3x+9) is the answer.
