What is the volume of a hemisphere with a radius of 9.2 cm, rounded to the nearest tenth of a cubic centimeter?
Answer:
volume of the hemisphere ≈1577.5 cm³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
= [tex]\frac{4}{3}[/tex]πr³ ÷ 2
=[tex]\frac{2}{3}[/tex] πr³
WHERE r is the radius
from the question given, radius= 9.2 cm
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the equation
volume of a hemisphere = [tex]\frac{2}{3}[/tex] πr³
= [tex]\frac{2}{3}[/tex] × 3.14 ×9.2³
= [tex]\frac{2}{3}[/tex] × 3.14 ×753.571
≈1577.5 cm³ to the nearest tenth of cubic centimeter
volume of the hemisphere ≈1577.5 cm³

Come up with your own system to measure angles. What would you call your unit of measure and how would it work. Describe your system and give some examples of typical angle measures like the corner of a room or a slice of pizza.
Answer:
You can try a picture memory method to help students
An example write down notes of what the triangle laws are for angles.
Then interpret them into your picture measurement theory.
Example could be the perpendicular measures of a right angle can be used
to find an area would be the M but as we are finding angles we could use the Big A instead of degrees sign.
We could provide pictures of cars to represent trigonometry
Where back wheels opposite angles and sides from slant are both the unit measure used in Side/sin( A) x sin (B) so this way you label the car wheel angle above of the square boot 'side on' and this angle is A
The B is the one above it linking the slant to find the other measure.
You are asked to design a theme around measuring angles so you need to look at other sin cos and tan calculus to design a picture that can create an image like i've given to find slant.
You need to one that finds angles.
However if you do find a car can help you can always call it square boot as in square root, considering 2/3 of sin cos and tan are square root measures.
Step-by-step explanation:
See the attached ideas and trigonometry
Picture memory Trigonometry
Picture 1. Sunrise Ah side looks for side measure.
The number above is the hypotenuse
A/H = cos ( ) x hyp =base A/H = cos ( ) x hyp = side
Picture 2.Sunrise Soh looks for side measure.
The number above it is the hypotenuse
O/H = sin ( ) =p (for product) take the p x hyp.
Picture 3 Sunrise Toast (Toa) looks for side measure = O/A
Tan ( lower angle ) x base = side
Picture 4 Side of car (Soh) with window as hypotenuse.
Two wheels are the 2 angles given and the back seat is perpendicular to both wheels =
so the triangle structure looks like this /00|7
so you type in 7/sin ( 1st wheel) x (2nd wheel) = hypotenuse.
Both angles given or worked out this is when this is used.
Picture 5 Electric mast looking for slope SIN =S/P = O/A
Angle at top
We have the side at 70 and looking for the slope
Sin( top angle) = p then side/p = hyp
Picture 6
Top angle and base given creates a T this means half both of them before dividing.
To find hypotenuse
Half = 1/2 base / sin (1/2) = hypotenuse
Picture 7
Top angle and base given creates a T this means half both of them before dividing.
To find height =
Half = 1/2 base /Tan 1/2) = Triangle height.
Key checker after pictures are drawn is;
sunrise = low angle x side or low angle x base = hypotenuse.
car = backseat x wheels = hypotenuse always remember when car on side the first
wheel first, second wheel 2nd first in the calculator. The wheels are the 2 angles that
make the car when flipped.
Half = 1/2 base / sin (1/2) = hypotenuse
Half = 1/2 base / tan (1/2) = height
Just take care with top angle and lower angle key words in the drawing descriptions and then the pictures will help.

Math problem: You are enlarging a photo on your computer screen. The photo starts at 3 centimeters wide. Each time you enlarge the photo, its width is doubled. You enlarge the photo four times. What is the final width of the photo on your screen?
Answer:
48 centimetres wide
Step-by-step explanation:
you are at 3
you enlarge it and you get 6
second enlargement you get 12
third enlargement you get 24
fourth enlargement you get 48
if you times 3 by 4 you are not doubling the width each time you enlarge the photo
so it is easier to double it each time you enlarge it

Consider the following graph of function f.
Which transformations will change function f into function g given below.
Answer:
2nd and 6th options
Step-by-step explanation:
y = |x+4| - 4 has a vertex of (-4, -4), and the vertex of the given graph is (3, 1). The shift between the first and second points given is 7 units to the left (6) and 5 units down (2)
The transformation that will change from f to g will be
the verical shift down 5 unitsthe horizontal shift left 7 unitsWhat is corner of a function?Corner point of a function is the point where continuous function will not be differentiable.
here the function in the graph has the corner point at (3,1).
so now we have to transform the function f to function g where
g(x)= |x+4|-4
in the function g(x) the corner point will be the point where the value changes sudddenly.
so the corner point will be x+4=0
⇒x=-4
at x=-4, the value of the g(x)=|-4+4|-4=-4
so the corner point of function g will be (-4,-4).
Now the corner point of function f is (3,1).
Therefore to trnsform function f to g we have to first displace (3,1) to (-4,-4).
in x direction the displacement will be = -4-3 =-7 i.e. horizontal shift left 7 units
in y direction the displacement will be =-4-1=-5 i.e. verical shift down 5 units
Therefore the transformation that will change from f to g will be
the verical shift down 5 unitsthe horizontal shift left 7 unitsLearn more about corner point

There are 20 cars competing in a race. In how many ways can the cars be awarded first, second, and third place?
826,880
6,840
1140

Please help me!
Answer:
6,840
Step-by-step explanation:
The total number of possible ways in which the position can be awarded are 1140.
What is the formula to expand the combination function f(n, r) = C(n, r)?We can write the combination expansion formula as -
f(n, r) = C(n, r) = n!/(n - r)!r!
Given is that there are 20 cars competing in a race. We have to find in how many possible ways can the cars be awarded first, second, and third place.
Total number of cars = {n} = 20
Total number of positions = {r} = 3
Total number of ways in which the position can be awarded -
C(20, 3) = 20!/(20 - 3)!3!
C(20, 3) = 20!/17!3!
C(20, 3) = (20 x 19 x 18 x 17!)/(17! x 3 x 2)
C(20, 3) = (20 x 19 x 18)/6
C(20, 3) = 20 x 19 x 3
C(20, 3) = 1140
Therefore, the total number of possible ways in which the position can be awarded are 1140.

What is the area of this shape?
Answer:
272 ft^2
Step-by-step explanation:
The lower rectangle is 10 ft by (12+8) or 20 ft
The area is
A = l*w = 10 *20 = 200 ft^2
The upper rectangle is 8 ft by (19 -10) or 9 ft
A = l*w = 8* 9 = 72 ft^2
The total area is 200 + 72 = 272
F and H are sets of real numbers defined as follows.
F={w | w>3}
H={w | w>6}
Write FUH and Fn H using interval notation.
If the set is empty, write Ø.
Answer:
[tex](a)F \cup H=(3, \infty)\\(b)F \cap H=(6, \infty)[/tex]
Step-by-step explanation:
Given the sets F and H of real numbers defined as given:
F={w | w>3}
H={w | w>6}
To write a set in interval notation, we use these brackets, ( ) for < or > while we use [ or ] for [tex]\leq $ or \geq[/tex].
Since our sets are defined by strict inequalities(< or >)
In interval notation
[tex]F=(3,\infty), H=(6,\infty)[/tex]

Its x-coordinate is 4
Write down the coordinates of this point.
Answer:
(4, 10)
Step-by-step explanation:
It gives the x coordinate of 4. The y coordinate is found when you plug the x value into the equation. This makes it y = 3(4) - 2. This equals y = 10. So the y coordinate is 10
Answer:
the coordinates are (4,10)
Step-by-step explanation:
y = 3(4) - 2
y = 10
x = 4
