Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k
IF ME is a diameter, the length of TE is 6, and the length of MT is 8, what is the EXACT circumference of circle D?
Answer:
10π
Step-by-step explanation:
Since ME is the diameter of the circle,
angle MTE = 90° (∠ in semicircle)
By pyth. theorem we can obtain,
ME = √8² + 6²
ME = 10
The diameter of the circle is 10
The circumference of circle D is 10π
Answer:
<MTE =90°
the inscribed angle from the diameter is 90°
in triangle MTE
MT=8 unit
TE=6unit
by using Pythagoras law
D=ME=√(8²+6²)=10 unit
radius =D/2=10/2=5unit
circumference of circle D=2πr=2π×5=10π or31.4unit

Which method correctly solves the equation using the distributive property?
Negative 0.2 (x minus 4) = negative 1.7
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x minus 4 = negative 1.7.
Negative 0.2 x = 2.3. x = negative 11.5.
Negative 0.2 (x minus 4) = negative 1.7.
x minus 4 = 0.34. x = 4.34.
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x + 0.8 = negative 1.7.
Negative 0.2 x = negative 2.5. x = 12.5.
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x minus 0.8 = negative 1.7.
Negative 0.2 x = negative 0.9. x = 4.5.
Answer:
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x + 0.8 = negative 1.7.
Negative 0.2 x = negative 2.5. x = 12.5.

5. A robot that picks up tennis balls is on a straight path from (8,6) toward a ball at (-10,-5). The robot picks up a ball at (-10,-5) and then turns 90° right. What are the coordinates of appoint that the robot can move toward to pick up the last ball?
Answer:
Step-by-step explanation:
so this question is about perpendicular lines. keep in mind that a perpendicular line has a reciprocal slope of opposite sign, from the line it's perpendicular to . :) okay so what is that line the robot is on, let's first
find the slope , m
m = (y2 - y1) / ( x2 - x1)
P1 = (8,6) in the form ( x1,y1)
P2= (-10,-5) in the form (x2,y2)
then
m = (-5-6) / (-10-8)
m = -11 / -18
m = 11/ 18
and then lets use the point-slope formula with the slope we just found and one of the given points, let's pick P1
y-6 = 11/18(x-8)
y = 11/18x - 88/18 + 6
y = 11/18x -88/18 + 108/18
y = 11/18x + 20/18
now let's take the reciprocal of the slope and change the sign, then we have
y = - 18/11x +20/18 ( coordinates robot can move on )
on the graph I'm attaching the green line is the one where the robot first moves, then the purple one.. is the one it turns 90 ° on to .

Answer:
580 cm
Step-by-step explanation:
To find the surface area you just need to find the area of every side of the box and add them together.
SO- the equation for this would be
SA (Surface Area) = 2(20 x 10) + 2(20 x 3) + 2(10 x 3)
SA = 2(200) + 2(60) + 2(30)
SA = 400 + 120 + 60
SA = 520 + 60
SA = 580

Julio bought a fish tank shaped like a rectangular prism. The inside of the tank measures 24 inches in length, 10 inches in width, and 12 inches in height. The tank is filled with water to a height of 8 inches. How many more cubic inches of water are needed to fill the tank to the top? Use paper to show your work.
Answer:
[tex]Volume = 960in^3[/tex]
Step-by-step explanation:
Given
Empty Tank
[tex]Length = 24in; Width=10in; Height = 12in[/tex]
When filled with water, the height is:
[tex]Height = 8in[/tex]
Required
Determine how many more cubic inches needed
First, we calculate the difference between the height of the tank and the height of the water.
[tex]H = 12in - 8in[/tex]
[tex]H = 4in[/tex]
The volume of water to full the tank is then calculated as:
[tex]Volume = Length * Width * H[/tex]
[tex]Volume = 24in * 10in * 4in[/tex]
[tex]Volume = 960in^3[/tex]
20 points AND brainliest. Write an equation in slope intercept form to represent the table above. For example: y = 36x + 36. Please put enter a space after each term as shown in the example.
Answer:
This is a ratio table,so therefore there is always a pattern.
Step-by-step explanation:
In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is not even,or the numbers are not even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.
Convert 639 into quinary system
Step-by-step explanation:
To convert decimal number 639 to quinary, follow these steps:
Divide 639 by 5 keeping notice of the quotient and the remainder.Continue dividing the quotient by 5 until you get a quotient of zero.Then just write out the remainders in the reverse order to get quinary equivalent of decimal number 639.Using the above steps, here is the work involved in the solution for converting 639 to quinary number:639 / 5 = 127 with remainder 4127 / 5 = 25 with remainder 225 / 5 = 5 with remainder 05 / 5 = 1 with remainder 01 / 5 = 0 with remainder 1Then just write down the remainders in the reverse order to get the answer, The decimal number 639 converted to quinary is therefore equal to :

A loan of$8000 was repaid in 24 equal monthly installments of $400 . The rate of interest on the loan was
Answer:
1%
Step-by-step explanation:
24(400) = 9600 = total amt paid
9600 - 8000 = 1600 = amt of interest paid
I = PRT T = 2 yr
1600 = 8000(2)R
1600 = 16000R
1600/16000 = 1/10 = .01 = 1%

D 112 inches
Answer:
B. 56π
Step-by-step explanation:
Circumfrance = 2πr OR πd(r*2)
C = 2π(28) -> C = 56π
OR
C = π(28*2) -> C = 56π
Answer:
B (56π)
Step-by-step explanation:
Circumference = 2πr or πd
C = 2π(28) (after completing this step:) C = 56π
Thus, C = 56π

The perimeter of an equilateral triangle is 12\/3 cm. Find the radius, apothem and area of the equilateral triangle.
Answer:
Radius - 4
Apothem - 2
Area - [tex]12\sqrt{3}[/tex] or 20.8
Step-by-step explanation:
Try to draw out my explanation so you know what this looks like.
~~~~
This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...
[tex]12\sqrt{3} \div3 = 4\sqrt{3}[/tex]
Now that we know the side lengths, we can get this started!
~~~~
Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.
4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.
[tex]Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6[/tex]
By the way, the formula for the area can be either of the two:
[tex]A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS[/tex]
we can easily find the area using the first formula.
[tex]A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}[/tex]
The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...
So we can divide the big triangle into a mini triangle at the bottom left/right
The height (small leg) of that triangle would be the apothem
The hypotenuse of that triangle would be the radius.
I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius
