The formula to find the circumference of a circle is 2 x pi (π) x radius. The radius is half of the diameter. Therefore, since the diameter is 20, the radius is 10. Pi is equal to approximately 3.14.
3.14 x 10 x 2 is 62.8.
The circumference of the circle is 62.8 m.
-4.3 g equals 25.8 solve for G

Answer:
Quadrants I and II.
O: (-2, 2)
N: (-2, 4)
M: (1, 4)
P: (1, 2)
Step-by-step explanation:
When rotating about the origin 90 degrees in a counterclockwise direction, focus on the coordinates of one point on the preimage at a time. So, the x-coordinate on the image will be the opposite of the y-coordinate of the preimage, and the y coordinate of the image will be the x-coordinate of the preimage. That sounds complicated so here is an example from the problem.
O is a point on the preimage. Its coordinates are (2, 2). To find the x-coordinate, take the opposite of the image's y-coordinate. The y-coordinate is 2, so it will be a -2 x-coordinate on the image. To find the y-coordinate on the image, take the x-coordinate of the preimage (O). The x-coordinate of O is 2, so the y-coordinate of the image will be 2. Combine those together and after a 90 degree counterclockwise rotation, you get a point of (-2, 2)
Answer:
Step-by-step explanation:
when rotate counterclock wise 90 degrees:
(x,y)⇒(-y,x)
points (2,2) (4,2) (2,-1) (4,-1)
CCW90 degrees (-2,2) (-2,4) (1,2) (1,4)
CCW 270 degrees (2,-2) (2,-4) (-1,-2) (-1,-4)
(x,y)⇒(y,-x) the shape will be in quadrant 3 and 4

15. A photoelectron experiment is performed on a sample of silicon using photons with an energy
of 1.43 x 105 kJ/mole. Photoelectrons are generated that have a kinetic energy of 1.34 x 10
kJ/mole. What was the ionization energy of these electrons?
Answer:
9.0×10^3K/moles
Step-by-step explanation:
ionization energy of these electrons = Energy of photons - kinetic energy of the electrons
Given
Kinetic energy of electron = 1.34×10^5
Energy of photons = 1.43 x 105 kJ/mole
Required
Ionization energy of these electrons
Ionization energy of these electrons = 1.43×10^5-1.34×10^5
ionization energy of these electrons = 0.09×10^5 kJ/mol
= 9.0 × 10^3 kJ/mol
Hence the ionization energy of these electrons is 9.0×10^3K/moles
The volume of a cylinder is given by the formula V=πr²h, where r is the radius of the cylinder and h is the height. Suppose a cylindrical can has the radius (x+8) and height (2x+3). Which expression represents the volume of the can?
A: πx³+19πr²+112πx+192π
B: 2πx³+35πx²+80πx+48π
C: 2πx³+ 35πx²+176πx+192π
D: 4πx³+ 44πx²+105πx+72π
Answer:
C
Step-by-step explanation:
We know that the volume of a cylinder is given by the formula:
[tex]V=\pi r^2h[/tex]
And we want to find the expression that represents the volume when the radius is (x+8) and the height is (2x+3).
So, let's substitute (x+8) for r and (2x+3) for h. This yields:
[tex]V=\pi (x+8)^2(2x+3)[/tex]
Let's expand.
Expand the square term first. We can use the perfect square trinomial pattern, which is:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
Here, our a is x and b is 8. So:
[tex]V=\pi (x^2+2(x)(8)+(8)^2)(2x+3)[/tex]
Simplify:
[tex]V=\pi (x^2+16x+64)(2x+3)[/tex]
Expand further. This time, we will use the distribute property. So:
[tex]V=\pi ((x^2+16x+64)(2x)+(x^2+16x+64)(3))[/tex]
Multiply:
[tex]V=\pi((2x^3+32x^2+128x)+(3x^2+48x+192))[/tex]
Combine like terms:
[tex]V=\pi((2x^3)+(32x^2+3x^2)+(128x+48x)+(192))[/tex]
Add:
[tex]V=\pi(2x^3+35x^2+176x+192)[/tex]
Distribute the π:
[tex]V=2\pi x^3+35\pi x^2+176\pi x+192\pi[/tex]
So, our answer is C.
And we're done!
Answer:
C
Step-by-step explanation:
V=πr²h
V=π(x^2+64)h
V=π(x^2+64)(2x+3)
V=π(2x^3+3x^2+128x+192)
C: 2πx³+ 35πx²+176πx+192π
Use the distributive property to rewrite the expression.

A. (0, −12)
B. (2, 2)
C. (4, 8)
D. (5, 13)
Answer:
Your answer option is B) (2,2)
Answer:
Step-by-step explanation:Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.
The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

Answer:

Step-by-step explanation:
Add all the numbers up, then divide it by how many numbers there are in the set.
3(x + 1) = -2(x - 1) + 6.
Answer:
x = 1
Step-by-step explanation:
first you distribute : 3(x + 1) -> 3x -2(x - 1) -> -2x + 2
next you combine like terms : 2 + 6 = 8
3x + 3 = -2x + 8
subtract 3 from both sides : 3x = -2x + 5
add 2x to both sides : 5x = 5
divide both sides by 5 and you get : x = 1

1. A rectangular field has one side fence 500 meters long, and another side fence
700 meters long
What is the length of a diagonal across the field?
b. What is the angle between the diagonal and the long side fence?
a
Answer:
[tex]d=860.23\ m[/tex]
[tex]\theta=35.54^\circ[/tex]
Step-by-step explanation:
Rectangles
The sides of the rectangular fields are 500 meters and 700 meters. The diagonal of the rectangle can be calculated as the hypotenuse of the right triangle formed by the two sides, thus:
[tex]d=\sqrt{x^2+y^2}[/tex]
Where x and y are the lengths of the sides. For the rectangular field, we have:
[tex]d=\sqrt{500^2+700^2}=\sqrt{250000+490000}=\sqrt{740000}=860.23\ m[/tex]
The angle between the diagonal and the longest side can be calculated using trigonometry. Please refer to the image attached.
[tex]\displaystyle \cos\theta=\frac{x}{d}=\frac{700}{869.23}=0.8137[/tex]
[tex]\boxed{\theta=35.54^\circ}[/tex]

Answer:
4
Step-by-step explanation:
The Significant Figures are 9 8 0 7
can someone pls help
Answer:
no, no, yes, no
Step-by-step explanation:
Starting with <EDG=43
You need to find <CDF. AB is a straight line, making it 180.
ADC=90 and FDB=20
180-90-20 to get CDF
70=CDF 70 doesnt equal 43
CDF and EDG are not congruent.
Find EDA. GC=180 ADC= 90 EDG=45
180-90-45
45
you can also see that ADC and EDG are adjacent angles and if you look, GDA makes up a right angle which is 90 so you could subtract the 45 from that to get 45 as well.
ADB=180
45+133=178
no
We already figured out that CDF=70
70+20=90 so yes.
BDG is obviously a right angle but looks can be deceiving so math wise
AEG is 90 and AB is 180
180-90=90
so BDG is 90
20+90+43=180
155=180
no

What is Slope?
describe what slope is,
Use at least TWO sentences!
Answer:
BET LETS GO
Step-by-step explanation:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between any two distinct points on a line.
