Answer:
[tex]\frac{2}{k+2}[/tex]
Step-by-step explanation:
Given the expression:
[tex]\frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}[/tex]
We are to find the product as shown:
[tex]= \frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{k^2-2^2} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{(k-2)(k+2)} * \frac{k-2}{2k+1}\\\\= \frac{2}{k+2} * 1\\\\= \frac{2}{k+2}[/tex]
Hence the required function is [tex]\frac{2}{k+2}[/tex]

Answer:
x = 12
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 81 = 15²
x² + 81 = 225 ( subtract 81 from both sides )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12

Which ordered pair represents a solution to both equations
Answer: (-3,3)
Step-by-step explanation:Answer: (-3,3)
Step-by-step explanation: P= IRT solve for T To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side. IRT means that I and R are multiplied by T. To get rid of them we must do the opposite of multiply, which is divide. But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side. So if we divide the right side by IR, we must also divide the left side by IR

Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hundredth.
Given:
For cylinder P: radius = 4.25 in. and height = 14 in.
For cylinder Q: radius = 7 in. and height = 8.5 in.
To find:
The volume of each cylinder.
Solution:
Volume of a cylinder is
[tex]V=\pi r^2h[/tex]
where, r is radius and h is height. Use 3.14 for [tex]\pi[/tex].
Using the above formula, the volume of cylinder P is
[tex]V_P=(3.14)(4.25)^2(14)[/tex]
[tex]V_P=794.0275[/tex]
[tex]V_P\approx 794.03[/tex]
Using the above formula, the volume of cylinder Q is
[tex]V_Q=(3.14)(7)^2(8.5)[/tex]
[tex]V_Q=1307.81[/tex]
Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
The volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.
What is the volume of a right circular cylinder?Suppose that the radius of the considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The given information is
For cylinder P:
radius = 4.25 in. and height = 14 in.
For cylinder Q:
radius = 7 in. and height = 8.5 in.
To find the volume of each cylinder.
The volume of a cylinder
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
where r is radius and h is height.
Using the above formula,
the volume of cylinder P
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
[tex]V = 3.14 \times (4.25)^2 \times 14 \: \rm unit^3\\\\V = 794.03[/tex]
The volume of cylinder Q
[tex]V = \pi r^2 h \: \rm unit^3\\\\V = 3.14 \times 7^2 \times 8.5 \: \rm unit^3\\\\V =1307.81[/tex]
Therefore, the volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.

Add 2 mn, -4 mn, 8 mn, -6 mn
Answer:
0
Step-by-step explanat
Answer:
0 mn
Step-by-step explanation:
First you would write the equation 2+(-4)+8+(-6)
Now let’s solve starting from the left.
2+(-4) = -2
This is the equation so far: -2+8+(-6)
Then you would solve the right side 8+(-6) = 2
Now we have -2 + 2 which equals 0.
PS. You can also do in another way like 2-4+8-6. It’s the same method and concept.
Hope this helps!

write an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4
Answer:
We conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
Step-by-step explanation:
Given the line
y+2x=4
converting into the slope-intercept form y = mx+b where m is the slope
y = -2x+4
comparing with the slope-intercept form
Thus, the slope is: m = -2
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2
The slope of the new line perpendicular to the given line = – 1/m
= -1/-2 = 1/2
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/2 and the point (-3, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=\frac{1}{2}\left(x-\left(-3\right)\right)[/tex]
[tex]y-5=\frac{1}{2}\left(x+3\right)[/tex]
Add 5 to both sides
[tex]y-5+5=\frac{1}{2}\left(x+3\right)+5[/tex]
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
Therefore, we conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

origin?
What is the slope of the line shown in the graph? (4 points)
Answer:
a. or [tex]\frac{3}{-2}[/tex]
Step-by-step explanation:
Slope is equal to y1-y2 over x1-x2.
So the equation would be:
[tex]\frac{2-(-1)}{-3-(-1)}[/tex]
2-(-1)=2+1=3
-3-(-1)=-3+1=-2
So the answer is:
