Answer:
1. 1
1. 13π.
--
20
explain:
1. 1 because any any non-zero expression raised to the power of 0 equals 1
13π.
2. --. because to convert into radian measure multiply by. π
20. ----
180°
Y=1 because on each equation it needs 1 for it to be the answer
When you move down you subtract and when you move to the right you subtract when your moving up or to the left you add
Answer:
It started from the Origin(Sine graph). It curved upwards immediately it started... Meaning graph's amplitude is gonna be positive one
The Equation for a sine graph is ASin[B(x-C)] + D
A=Amplitude
B= 2π/period
C= c value at the starting point.
D= y value at starting point
Let your Starting point be at the sinusoidal axis (Max + Min)/2.
Looking at this graph
Let's take 1cm on the y axis to be 1unit(1,2,3,4...)
On the x axis... let's take 1cm to be π units(π,2π,3π....)
To get the sinusoidal axis Max - Min/2
Since 1cm is 1unit
Max =1 (from the graph)
Min= -1
1-1/2 = 0
The axis is at the center of middle
Meaning
D=y=0(Its directly at the x axis)
From this axis at the origin... The graph goes... Intercept Maximum... intercept Minimum... Meaning its a Positive sine graph.
A=amplitude = 1cm
B=Period...(Time to complete one Oscillation)
It doesn't fall directly on an x value... It falls at the 1.9th position. or 19/10
B=2π/Period.
B=2π/19/10
B=2π x 10/19
B=20π/19
C=0
Writing the Equation
Y= 1Sin[20π/19(x-0)] +0
ie
Y = Sin [20πx/19]
My thoughts on it
Correct me if wrong... Thanks
Answer:
6:5:2
Step-by-step explanation:
We need the amounts for v to be equal, so
u:v = 12:10 v is 10
v:w = 25:17 v is 25
Multiply the first ratio by 2.5 to get an equivalent amount for v
u:v = 30:25
so u:v:w = 30:25:10
They can all be divided by 5
6:5:2
