What evidence is there in the document that the marchers were disciplined
Answer:
The evidence is the statement made in the document where it was said: "You will be beaten but you must not resist; you must not even raise a hand to ward off any blows"
Step-by-step explanation:
The document has been attached. It was from the march by gandhi's followers to the dharasana salt works.
From the document attached, the evidence that they were disciplined is where it was said: "You will be beaten but you must not resist; you must not even raise a hand to ward off any blows"
A cylinder with a radius of 4 cm and a height of 9 cm has the same volume as a cone with a radius of 3 cm. What is the height of the cone?
Answer:
D. 48 cm
Step-by-step explanation:
Cylinder Volume:
V=πr^2h
V≈452.39
Cone Volume:
V=πr^2(h/3)
452.39 = pi(3)^2(h/3)
452.39 = pi x 9 x (h/3)
452.39 = 28.26 x (h/3)
/28.26 /28.26
16.008138712 = (h/3)
x 3 x 3
h = 48.0244161359
h = 48 cm
Please answer the question below (ABOUT VECTORS AND MAGNITUDE)
(a) v appears to have a fixed direction along the positive x-axis. If ||u|| = 150 N, ||v|| = 220 N, then when θ = 30°, you have
u = (150 N) (cos(30°) i + sin(30°) j ) ≈ (129.904 i + 75 j ) N
v = (220 N) (cos(0°) i + sin(0°) j ) = (220 i ) N
(i and j are the unit vectors in the positive x and y directions)
and their sum is
u + v ≈ (349.904 i + 75 j ) N
with magnitude
||u + v|| ≈ √((349.904)² + (75)²) N ≈ 357.851 N ≈ 357.9 N
and at angle φ made with the positive x-axis such that
tan(φ) ≈ (75 N) / (349.904 N) → φ ≈ 12.098° ≈ 12.1°
(b) Letting θ vary from 0° to 180° would make v a function of θ :
u = (150 N) (cos(θ) i + sin(θ) j ) = (150 cos(θ) i + 150 sin(θ) j ) N
Then
u + v = ((220 + 150 cos(θ)) i + (150 sin(θ)) j ) N
→ M = ||u + v|| = √((220 + 150 cos(θ))² + (150 sin(θ))²) N
M = √(48,400 + 66,000 cos(θ) + 22,500 cos²(θ) + 22,500 sin²(θ)) N
M = 10 √(709 + 660 cos(θ)) N
(c) As a function of θ, u + v makes an angle α with the positive x-axis such that
tan(α) = (150 sin(θ) / (220 + 150 cos(θ))
→ α = tan⁻¹((15 sin(θ) / (22 + 15 cos(θ)))
(d) Filling in the table is just a matter of evaluating M and α for each of the given angles θ. For example, when θ = 0°,
M = 10 √(709 + 660 cos(0°)) N = 370 N
α = tan⁻¹((15 sin(0°) / (22 + 15 cos(0°))) = 0°
When θ = 30°, you get the same result as in part (a).
When θ = 60°,
M = 10 √(709 + 660 cos(60°)) N ≈ 323.3 N
α = tan⁻¹((15 sin(60°) / (22 + 15 cos(60°))) = 23.8°
and so on.
Write a quadratic function in standard form whose graph satisfies the given conditions.
passes through
0, 0 , 2, 4 , and 4, 0
Answer:
y = -x² + 4xStep-by-step explanation:
The standard form:
y = ax² + bx + cPairs given:
(0, 0), (2, 4), (4, 0)Substitute values of x and y and work out the values of a, b and c.
1. Point (0, 0)
0 = a(0)² + b(0) + c ⇒ c = 02. Point (2, 4)
4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a3. Point (4, 0)
0 = a(4)² + b(4) ⇒ 16a + 4b = 0Substitute b and solve for a:
16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1Find b:
b = 2 - 2(-1) = 2 + 2 = 4The function is:
y = -x² + 4x
If 3000 is placed in an account at 5% interest and is compounded quarterly for 5 years.How much is in the account at the end of 5 years?
Answer:
FV= $3,846.11
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,000
Number of periods (n)= 5*4= 20 semesters
Interest rate (i)= 0.05/4= 0.0125
To calculate the Future Value, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 3,000*(1.0125^20)
FV= $3,846.11

Find the value of x. plz helpp
Answer:
x=45°
Step-by-step explanation:
180-90=90
Hence, there is 2 x so 90/2=45
Answer:
x = 45°
Step-by-step explanation:
here's your solution
=> we know that sum of all angles of traingle = 180°
=> x° + x° + 90° = 180°
=> 2x + 90° = 180°
=> 2x = 180° - 90°
=> 2x = 90°
=> x = 90°/2
=> x = 45°
hope it helps

Joe has 6 frogs, 8 hamsters, 9 goldfish, and 3 snakes. What is the ratio of Joe's frogs and snakes to hamsters?
Answer:
9:8
Step-by-step explanation:
According to the word problem, Joe has 6 frogs, 8 hamsters, 9 goldfish, and 3 snakes.
The question is asking the ratio of Joe's frogs AND snakes TO hamsters.
To find out the ratio of frogs and snakes, add how many frogs there are to how many snakes there are.
6 + 3 = 9.
The last part of the equation should be obvious.
There are 8 hamsters.
Therefore, the ratio of Joe's frogs and snakes to hamsters is 9:8.

if the ratio of type O to non-type O donors at a blood drive was 37:43. how many would be type O out of 300 donors? will try and mark brainliest . please show the work as well
Answer:
Step-by-step explanation:
Proportion of type O donors = 37/(37+43) = 37/80
300 × 37/80 = 138.75
139 donors out of 300 are type O.
A ratio shows us the number of times a number contains another number. The number of type O donors out of 300 is 139.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the ratio of type O to non-type O donors at a blood drive was 37:43. Therefore, the number of type O blood donors be represented by 37x and the number of non-type O blood donors be represented by 43x.
Now, the sum of type and non-type O donor is 300. Therefore, we can write,
37x + 43x = 300
80x = 300
x = 3.75
Further, the Number of type O donors out of 300 can be written as,
Number of type O donors out of 300 = 37x = 37(3.75) = 138.75 ≈ 139
Hence, the number of type O donors out of 300 is 139.
