The amplitude of the function y = sin 5лx is found as 1.
What is defined as the amplitude of function? The maximum deviation of a variable out of its mean value is referred to as its amplitude. The amplitude formula aids in the calculation of the cosine and sine functions. A is the symbol for amplitude. The amplitude formula can also be conveyed as the average of the sine or cosine function's maximum and minimum values.The sine (or cosine) function can be written as,
x = A sin (ωt + ϕ) or x = A cos (ωt + ϕ)
x = displacement of wave (meter)A = amplitudeω = angular frequency (rad/s)t = time periodϕ = phase angleTo find the variables used to calculate the amplitude, use the formula;
y = asin(bx - c) + d.
Where a is the amplitude.
The given equation of function is y = sin 5лx.
Comparing the function with the standard form
a = 1
Thus, the amplitude of the function y = sin 5лx is found as 1.

how many nonzero complex numbers zz have the property that 0, z,0,z, and z^3,z 3 , when represented by points in the complex plane, are the three distinct vertices of an equilateral triangle?
Consequently, there exist four numbers z:
√3/2 ± I 1/2
-√3/2 ± I 1/2
The three unique vertices of an equilateral triangle are 0, z, and z3: (z^3=0)= e ^iπ/3(z -0 ) ⇔ z^3=e^(±iπ/3)z
=(z^2-e^±iπ/3)z=0⟺z=0
or z^2=e^±iπ/3
Since we have z[tex]\neq[/tex]0, z=e^±iπ/6= ±(√3/2 ± I 1/2 )
There are thus four numbers in z:
√3/2 ± I 1/2

A bottle of maple syrup in Wayne’s freezer needs to be warmed for breakfast. Sitting on the kitchen counter, the bottle temperature will go up a steady 9.6° C every hour. If the bottle temperature begins at the freezer temperature of –16° C, how many hours will it take to reach 20° C?
Change in temperature: (20 – (–16)) = 20 + 16 = 36
It will take the bottle of maple syrup 3 hours 45 minutes to reach 20° C from –16° C.
How to get the temperature changegiven data
the bottle temperature will go up a steady 9.6° C every hour
freezer temperature = –16° C
final temperature = 20° C
The temperature rise from –16° C to 20° C
from –16° C to 0° C = 16° C
from 0° C to 20° C = 20° C
adding both increments gives = 20 + 16 = 36° C
if every hour we have 9.6° C then how many hours will give 36° C
1 hour = 9.6° C
? hour = 36° C
we cross multiply to have
= 36 * 1 / 9.6
= 3.75
This is 3 hours then a fraction of some minutes, the fraction is gotten by
0.75 * 60 = 45
Therefore the time to reach 20° C is 3 hours 45 minutes

A pair of shoes usually sells for $68 if the shoes are 40% off and sales tax is 6% what is the total price of the shoes including tax
Usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.
As given in the question,
Given that:
Usual selling price of shoes = $68
Discount on shoes =40%
Discounts an amount or percentage from something that they are selling, they take the amount or percentage off the usual price.
so, remove 40% from the price and you have left 60%
reduced price = 60% of $68
=60/100 * 68 = $40.8
Sales tax is 6% of reduced price= 6% of $40.8
=$2.448 upto 3 decimal digits
Now , price including tax =$40.8+$2.448 =$43.248
Hence, total price including tax= $43.248
Therefore, usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.

Answer:
x<-5.5 or x<-11/2
Step-by-step explanation:
2(4x+1)<3(2x-3)
1. First we need to expand the brackets
8x+2<6x-9
2. get the x on one side so we would -6x and -2 on each side
2x<-11
3. divide by 2 on each side as we want to get the value of x which gives
x<-11/2
the fraction can also be written as a decimal
x<-5.5
4) so, the final answer is
x<-5.5 or <-11/2

increase by 68m 2. Find the original dimensions.
The original dimensions are 12 m and 20 m.
What is area of rectangle?
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.
The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle.
Let x be the width of the rectangle.
Length of the rectangle = x+8
Area of the rectangle = x(x+8)
According to question, new width= x+2
New length = x+2+8 = x+10
New area = (x+2)(x+10)
Area increased = (x+2)(x+10) – x(x+8)
x^2+12x+20-x^2-8x=68
4x-20=68
4x=48
x=12
Hence, the width = 12m and length = 12+8 = 20 m

⚠URGENT!!!⚠The larger prism has had two identical holes carved out of it, each of which is a rectangular prism. Find the volume of the remaining solid, writing your answer correct to 2 decimal places. Note that all measurements are in meters.
Volume=_____m^3
The volume of the remaining solid correct to 2 decimal places is 3634.60 m³
Calculating VolumeFrom the question, we are to determine the volume of the remaining solid
Volume of the remaining solid = Volume of the larger prism - Volume of the rectangular prisms carved out
First, we will determine the volume of the larger prism
Volume of the larger prism = 17 × 17 × 17
Volume of the larger prism = 4913 m³
Now, we will determine the volume of one of the rectangular prism that was carved out
Volume = 4 × 9.4 × 17
Volume = 639.2 m³
∴ Volume of the two identical holes carved out = 2 × 639.2 m³
= 1278.4 m³
Thus,
Volume of the remaining solid = 4913 m³ - 1278.4 m³

Based on the equation of the line that is parallel to the first line, the equation of the line in slope-intercept form is y = 3/4x - 6³/₄
How to write the equation?First, find the slope of 3x + 4y = 7:
( 3x + 4y = 7) x 1/4
3/4x + y = 7/4
The slope is therefore 3/4x.
Lines that are parallel to each other have the same slope. You can therefore use this slope to find the formula of the other line by first solving for the y-intercept:
y = Slope(x) + y-intercept
