What is plank's constant
Answer:
6.626068 × 10-34 m2 kg / s
Step-by-step explanation:
The Planck constant, or Planck's constant, denoted h is a physical constant that is the quantum of electromagnetic action, which relates the energy carried by a photon to its frequency. A photon's energy is equal to its frequency multiplied by the Planck constant. The Planck constant is of fundamental importance in quantum mechanics, and in metrology it is the basis for the definition of the kilogram.

Answer: C) Outside the circle
Step-by-step explanation: Ok, so we know 0,0 is the center of the circle and 5,8 is on the circle, on the border. Therefore, anything more than 5,8 is outside the circle and anything less is inside the circle.
[tex]\sqrt{-15}[/tex] = -3.87
[tex]\sqrt{-74}[/tex] = -8.60
(-3.87, -8.60)
Therefore, the answer is outside the circle...pretend the rectangle is a circle...as you can see point Z will be outside the circle.
I hope this helps!
Answer: A-Inside the Circle
Step-by-step explanation: For point Z: the coordinate is (-3.9,8.6) rounded to the nearest whole and since the center of the circle is at (0,0) and a point on the circle is (5,8) then we know that every other point will be the same distance away from the circle. If (5,8) is a point on the circle then (-5,8), (-5,-8), and (5,-8) will also be points. If you plot all of these and draw a circle outline you will see that point Z falls in the circle.

a line with the slope of -1 passes through the point 0, 3 what is the equation in slope intercept form
Answer:
y = -x + 3
Step-by-step explanation:
Slope intercept form is the form y = mx+b where m is the slope and b is the y intercept
Plugging in the values we get y=-x+3
Answer:
y = - x + 3
Step-by-step explanation:
y = mx + b
Slope m = -1.
y = - x + b
Point (0,3).
3 = 0 + b
b = 3
y = - x + 3

y=3x+1 is in-fact linear. It is not a function though as it's y-intercept is 1 not 0. If you graphed this on a graphing calculator such as Desmos, it would create a line. It also uses slope-point formula which definitely makes it a line.

Answer:
55°
Step-by-step explanation:
In circle with center O, OA and OB are radii and PA and PB are tangents drawn from external point P.
Since, tangent is perpendicular to the radius of the circle.
[tex] \therefore m\angle PAO = m\angle PBO = 90°\\
m\angle APB = 70°....(GIVEN) \\[/tex]
In quadrilateral PAOB,
[tex] m\angle PAO + m\angle PBO+ m\angle APB \\+m\angle AOB = 360°\\
\therefore 90° + 90° + 70° +m\angle AOB = 360°\\
\therefore 250° +m\angle AOB = 360°\\
\therefore m\angle AOB = 360°- 250°\\
\huge \purple {\boxed {\therefore m\angle AOB = 110°}} \\[/tex]
Since, angle subtended at the circumference of the circle is half of the angle subtended at the centre of the circle.
[tex] \therefore m\angle ACB = \frac {1}{2} \times m\angle AOB\\\\
\therefore m\angle ACB = \frac {1}{2} \times 110°\\\\
\huge \orange {\boxed {\therefore m\angle ACB = 55°}} [/tex]
You have purchased 5 lottery tickets (each with different numbers) for tonight’s Pick 4. In the Pick 4, one ball (numbered 0 – 9) is drawn from each of four cylinders. What are your odds of winning?
Please help
Answer: 0.05%
Step-by-step explanation:
Ok, you have 5 tickets with different combinations of 4 numbers of them.
Now, the total number of combinations of 4 numbers (0 to 9) can be found as:
For the first number we have 10 options.
For the second number we also have 10 options.
for the third number we also have 10 options
for the fourth number we also have 10 options.
The total number of combinations is equal to the product of the number of options for each selection, this is:
Combinations = 10*10*10*10 = 100*100 = 10,000.
So out of 10,000 possible combinations, you have 5.
Then the odds of winning is the quotient between the combinations that you have and the total number of combinations: p = 5/10,000 = 0.0005
In percentage form, this is: 0.0005*100% = 0.05%
the figure is a rectangular prism. Identify which one of the line segments in the given figure is perpendicular to BF.
Answer:
EF, FG, AB and BC are perpendicular to BF.
Step-by-step explanation:
In the figure attached, a rectangular prism has been given.
Line BF is contained in the face BCGF of the prism.
Therefore, all the faces perpendicular to the face given are,
ABFE, EFGH, ABCD and CGHD.
But the line segments contained in these faces and perpendicular to the line segment BF are EF, FG, AB and BC.
Therefore, answer is the line segments EF, FG, AB and BC are perpendicular to BF.
Line segments perpendicular to BF are:
GF, EF, AB, and CB
What is perpendicular?Perpendicular lines are the two distinct lines that intersect at each other at 90°. A perpendicular is a straight line that makes an angle of 90° with another line. 90° is also called a right angle and is marked by a little square.
Given,
In figure ABCDEFGH is a rectangular prism
BF is an edge of the prism
All faces of the rectangular prism are perpendicular to each other
Face EFGH is perpendicular to face BCGF
⇒ GF⊥BF and EF⊥BF
Face ABCD is perpendicular to face BCGF
⇒ AB⊥BF and CB⊥BF
Hence, line segments GF, EF, AB, and CB are perpendicular to BF.

Answer:
8
Step-by-step explanation:
2×2×2=8
Answer:
8
Step-by-step explanation:
Point A is at (-8, 5) and point M is at (-1.5, 1). If M is the midpoint of line segment AB, what are the coordinates of point B?
Answer:
(5,-3)
Step-by-step explanation:
If point A is 6.5 on the x axis away from point M, then point B must be the same distance away. -1.5+6.5=5. If point A is 4 on the y axis away from point M then point B must also be the same distance away. 1-4=-3.
So the answer must be (5,-3)

What is a Circle?
A circle is a round-shaped figure with all the points on one plane, the distance between the center and all the points on the circumference is the same.
Thre arc mBC inscribes angle BDC
According to the theorem, the angle made by the arc on the center is double that made at the circumference.
mBDC = (1/2) * mBC
mBDC = (1/2) * 118 = 59°
It is also known from the secant theorem that, the angle made by the two secants is equal to half of the angle inscribing the arc.
mA = (1/2) * (mBC - mDE)
35 = (1/2) * (118 - mDE)
70 = 118 - mDE
The measure of DE = 48°
The sum of all the arcs in a circle is 360°
So,
mBC + mCD + mDE + mBE = 360
mCD = 360 - 118 - 48 - 76 = 118°
The angle CBD is inscribed by the arc mCD
mCBD = (1/2) * mCD = (1/2) * 118 = 59°
The angles CBD and BDC are equal, so the triangle is isosceles.

8 Batman cards, 12 Superman cards, and 5 captain America =25 cards
P( batman) = 8/25
no replacement since he hands them out
7 Batman cards, 12 Superman cards, and 5 captain America =24 cards
P( batman) = 7/24
P(batman, no replacement, batman) = 8/25 * 7/24 = 7/75

Answer:
A handyman need 34 rows of 18 tiles.
How many total tiles does he need?
lets start off by saying that each row has 18 tiles
and there are supposed to be 34 rows
so you can multiply the number of tiles in each row (18) by the number of rows (34)
34 x 18 = 612
the handyman needs a total of 612 tiles to cover the floor.

Triangle C and Triangle D
Step-by-step explanation:
If you look closely at all of the different triangles, you can see that there are two pairs of congruent triangles.
Triangle A and Triangle E are congruent, both being right triangles and approximately the same size.
Triangle B and Triangle F are congruent, as both of them are isosceles triangles, and again, the same size.
The two that remain, Triangles C and D, are both scalene triangles, but they are not congruent to one another. Triangle C clearly has a smaller obtuse angle than Triangle D.

Step-by-step explanation:
1) 1 mile = 5280 ft.
Area of both sides = 5280 ft × 8 ft × 2 sides = 84480 ft²
Since 1 person for each 4.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{4.5}[/tex]
the size of a crowd = [tex]\frac{1}{4.5} *84480=18773.33[/tex] ≈ 18700
2) 1 mile = 5280 ft, therefore 2 mile = 10560 ft (5280 × 2)
Area of both sides = 10560 ft × 10 ft × 2 sides = 211200 ft²
Since 1 person for each 4.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{4.5}[/tex]
the size of a crowd = [tex]\frac{1}{4.5} *211200=46933.33[/tex] ≈ 46900
3) 1 mile = 5280 ft, therefore 2 mile = 10560 ft (5280 × 2)
Area of both sides = 10560 ft × 10 ft × 2 sides = 211200 ft²
Since 1 person for each 2.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{2.5}[/tex]
the size of a crowd = [tex]\frac{1}{2.5} *211200=84400[/tex] ≈ 84500
4) 1 yard = 3 ft, therefore 100 yard = 300 ft (100 × 3)
Area of both sides = 300 ft × 50 ft × 2 sides = 30000 ft²
Since 1 person for each 2.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{2.5}[/tex]
the size of a crowd = [tex]\frac{1}{2.5} *30000=12000[/tex]
